Description

  The present invention is a bath shower, bathtub, oil-water separation, aquatic sacrifice, plant cultivation, washing machine, dishwasher, oral washer, drinking water generating device, cancer cell growth suppression, flush toilet, water purification device, car wash device, The present invention relates to an apparatus for generating gas microbubbles in a liquid used in an oil / water separator, a component washing apparatus, and the like.

  In the conventional microbubble generator, air is sucked by the suction side of the electric pump, the gas-liquid mixed flow is pumped by the electric pump, water is injected into the tank using a nozzle, and the gas-liquid mixed water is injected into the tank. Then, the crushed gas-liquid mixed water was released into water close to atmospheric pressure through a nozzle to supply microbubbles. Even if water is another liquid and air is another gas, gas microbubbles are supplied into the liquid based on the same principle.

As Comparative Example 1, Japanese Patent Application Laid-Open No. 2007-190466 is illustrated in FIG. FIG. 20 shows a conventional microbubble generator used for a bathtub. The flow of water and air is indicated by arrows. A gas-liquid mixing venturi 102 is provided on the suction side of the electric pump 101, and air is self-sucked through the gas inlet 103. The conventional microbubble generator is characterized in that air is self-sucked by utilizing the negative pressure on the suction side of the electric pump 101 in this way. The water is sucked from the suction pipe 104 that sucks the water in the bathtub and creates a gas-liquid mixed flow in the venturi 102. A gas-liquid mixed flow is injected into the tank 106 through the provided injection nozzle 107. The jetted gas-liquid mixed flow collides with the collision plate 1013 located immediately below the water surface 1014. The flow rate of the gas-liquid mixed flow ejected from the ejection nozzle 107 is adjusted using a water surface control device (not shown) so that the water surface 1014 is always at a fixed position in the tank 106.
As a result of this adjustment, the gas-liquid mixed flow always collides with a certain thin water layer between the collision plate 1013 and the water surface 1014 and collides with the collision plate with the same impact pressure. In this way, air is dissolved in water in the tank. The discharge port 108 is provided in the lower part of the tank, and the gas-liquid mixed flow in the tank is discharged from the discharge port 108, but the collision plate 1013 restricts the flow rate of the gas-liquid mixed flow discharged from the separate discharge port 108. I do not have the function to do. Therefore, the collision plate 1013 does not have a function of increasing the pressure in the tank 106.
As a result, the microbubbles generated in the water layer between the water surface 1014 and the collision plate 1013 and the water in which the air is dissolved naturally flow down to the lower part of the tank 106 and are discharged from the discharge port 108.
Water and microbubbles in which air is dissolved are supplied to the bathtub 1010 through the discharge port 108 and the decompression nozzle 109 and become microbubbles (fine bubbles) in the bathtub 1010 to precipitate in the water, and the water 1011 becomes cloudy. Reference numeral 1012 denotes a suction port for sucking water 21 from the bathtub 20.
The above is a so-called pressure-decompression microbubble generator, but other microbubble generators include a gas-liquid shearing method using a swirling flow (not shown), a venturi tube, etc. Microbubbles can be generated only in water to which is added.
There are devices that supply water and air to exceptionally powerful gear pumps, shear and stir the water and air with gear pumps, and then release them into the water to produce cloudy microbubble water. A pump must be used.

A conventional microbubble generator using a pressure-reducing method uses the electric pump 101 as described above, and the venturi 102 is provided on the suction side of the electric pump 101.
For this reason, for example, when used for bathing, a microbubble generator having electric wiring is brought into the bathroom, and there are safety problems such as electric shock and electric leakage.
In order to avoid this difficulty, the electric pump 101 shown in FIG. 20 may be taken out of the bathroom. However, a large-scale bathroom remodeling work is required and the price is increased.
An object of this invention is to provide the microbubble generator which does not use an electric pump in view of said difficulty.

In order to achieve the above object, the present invention uses a Venturi tube or aspirator 11 in which a check valve 15 is provided at the gas inlet 14 as shown in FIG. A check valve 13 may or may not be provided at the liquid (water) inlet 12 of the venturi tube or aspirator 11. However, a check valve 15 is provided at the gas inlet 14. Even when the check valve 13 is not provided at the liquid (water) inlet 12, the pressure in the semi-sealed tank 17 can be increased from the water pressure. This is because the gas-liquid mixed flow injected into the semi-sealed tank causes a known water tank effect and increases the pressure in the tank.
Of course, when the check valve 13 is provided at the liquid (water) inlet 12, the pressure in the semi-sealed tank 17 can be further increased as compared with the case where the check valve 13 is not provided. This is the principle of a water hammer pump.
For this reason, when the check valve 13 is provided, the pressure-resistant strength of the semi-sealed tank 17 is strengthened, and in the unlikely event that the pressure in the semi-sealed tank 17 increases excessively, mass producers should avoid accidents such as rupture and destruction. It is essential that mass producers conduct sufficient mass production tests and confirm safety. In addition, if the pressure in the semi-sealed tank 17 is excessively increased by providing the check valve 13, mass producers are sufficient to prevent the hose connected to the tank from rupturing or the screw part from coming off and causing an accident. It is essential for mass producers to confirm safety by conducting mass production tests. Otherwise, the check valve 13 must not be provided.

  Here, the structure of a known venturi tube is defined. If the middle part of the integrated liquid flow path is narrowed and the cross-sectional area of the flow path is reduced, the liquid pressure in the constricted part decreases according to Bernoulli's law. And gas are mixed to create a gas-liquid mixed flow.

Also, the structure of a known aspirator is defined. A rectifying pipe is provided at the entrance of the liquid flow path, and a liquid discharge nozzle and a receiving pipe for the discharged liquid close to the tip of the nozzle are provided along the liquid flow path downstream thereof. A rectifier pipe is a pipe that has the role of adjusting the flow of inflowing liquid and creating a spiral laminar flow or a straight laminar flow.
A plurality of holes are formed in the rectifying pipe along the liquid flow path, and the plurality of holes are twisted to each other, and the plurality of stream lines of the liquid that have passed through the rectifying pipe draw a spiral with each other. It is sent to the ejection nozzle. As a result, the liquid sent to the liquid jet nozzle while drawing a spiral with each other is well mixed with the gas, resulting in a gas-liquid mixed flow.
Further, the plurality of holes opened along the liquid flow path of the rectifying pipe do not necessarily have to be twisted with each other. In this case, the plurality of holes in the rectifying pipe are opened in parallel to each other, and the liquid stream lines are formed into a plurality of stream lines parallel to each other, and the spiral is not drawn and sent to the liquid ejection nozzle. Depending on the flow rate of the liquid, the holes in the rectifying tube may be parallel to each other.

The high-speed liquid ejected from the liquid ejecting nozzle entrains the gas in the gap between the liquid ejecting nozzle and the receiving tube to form a gas-liquid mixed flow and injects it into the receiving tube.
The difference between the Venturi tube and the aspirator is the aspirator in which the liquid ejection nozzle and the receiving tube are separated, and the venturi tube in which the gas inlet is perpendicular to the constricted portion of the integral flow path without being separated.

In FIG. 1, the liquid (water) flowing from the water supply 118 through the hose 117 passes through the check valve 13, flows into the liquid inlet 12, and passes through the narrow diameter portion of the venturi pipe or the aspirator 11. Since the pressure decreases, the gas (air) is self-absorbed from the gas inlet 14, and the gas (air) and the liquid (water) are mixed in the venturi tube or the aspirator 11 to form a gas-liquid mixed flow, and the injection hole 16 is sprayed from the top of the semi-sealed tank to the semi-sealed tank 17 and collides with the liquid (water) surface 19 in the semi-sealed tank and then the collision plate 111 at the bottom. As a result, the gas-liquid mixture in the semi-sealed tank is agitated. Further, since the collision plate 111 is provided in the vicinity immediately above the liquid discharge port 112, it has a function of limiting the flow rate of the gas-liquid mixed flow discharged from the liquid discharge port 112. Further, when the gas-liquid mixed flow collides with the collision plate 111, a water tank effect is generated by the impulse, and the pressure in the tank increases more than the water pressure. Therefore, although the pressure in the semi-sealed tank increases, the pressure in the tank 106 does not decrease below a certain value due to the effect of limiting the discharge amount of the gas-liquid mixed flow of the collision plate 111, and the gas (air) compared to the first comparative example. Dissolves in liquid (water) with greater solubility.
Reference numeral 111 denotes a collision plate provided in the vicinity immediately above the liquid discharge port 112 to the outside of the semi-sealed tank provided at the bottom of the gas-liquid mixing / semi-sealed tank 17.
This collision plate 111 promotes gas-liquid mixing of the liquid (water) 110 exiting from the gas-liquid mixing / semi-enclosed tank 17, resulting in finer bubbles, and the collision plate 111 is located in the vicinity immediately above the liquid discharge port 112. Therefore, the flow of the liquid discharged from the liquid discharge port 112 is restricted by the collision plate 111, and there is an effect of preventing the liquid pressure in the semi-sealed tank from being lowered below a certain level. Therefore, the pressure in the gas-liquid mixing / semi-sealed tank 17 is maintained at a predetermined pressure or higher. Not only that, the action of the collision plate 111 makes it difficult for large gas bubbles to exit the liquid outlet 112.

Conventionally, there has been an invention in which a gas-liquid mixed flow collides with a collision plate to cause cavitation, and fine bubbles are generated and released into a free water tank under atmospheric pressure.

Patent 1487118 (filed on Aug. 7, 1984) FIG. 1. This patent is shown in FIG.

However, this invention can only generate very low concentration of fine bubbles.
The cause is that the gas-liquid mixed flow ejected from the gas-liquid mixer 4 in FIG. 41 can collide with the collision plate 18 to cause cavitation, but the generated fine bubbles 22 are immediately generated as shown in FIG. Since it is discharged into the free water tank 16 under the atmospheric pressure, the air in the form of fine bubbles is not easily dissolved in the water 15 in the free water tank under the atmospheric pressure, and only a part of the air is dissolved. As a result, only a very low concentration of fine bubbles could be generated.

The inventor of the present invention made a prototype of the device shown in FIG. 1 of the above-mentioned Patent 1487118 “Micro Bubble Injector” and confirmed that very few fine bubbles were released into the free water tank under atmospheric pressure. It was confirmed that the water in the free water tank did not become cloudy, was transparent in appearance, and could only be a very low concentration microbubble generator.

For this reason, the above-mentioned patent 1487118 cannot be put into practical use as a microbubble generator, and its rights are canceled on July 14, 1993 due to non-payment of pension.

The object of the present invention is to solve the problem of the above-mentioned Patent 1487118 shown in FIG. 41 and to generate fine bubbles which become cloudy at a high concentration.
Therefore, in the present invention, the aspirator 11 as a gas-liquid mixer is attached above the semi-sealed tank 17 in FIG. 1 under a pressure higher than the atmospheric pressure, and the gas-liquid mixed flow ejected from the aspirator 11 is sent to the lower part of the semi-sealed tank 17. The gas is collided with a collision plate 111 provided in the vicinity immediately above the fluid discharge port 112 to break up the gas-liquid mixed flow to generate finer fine bubbles (microbubbles), and the pressure in the semi-sealed tank 17 is atmospheric pressure. Utilizing the higher pressure, the solubility of the gas in the liquid was improved and a large amount of highly concentrated and cloudy microbubbles were successfully generated.

When the water supply 118 is connected to the aspirator or the venturi tube 11 which is a gas-liquid mixer, when the water supply pressure is 2 kgf / square centimeter, the pressure in the semi-sealed tank 17 can be increased to 3 kgf / square centimeter or more.

The reason why such pressurization can be performed only with water pressure is as follows.
That is, the gas-liquid mixed flow that has passed through the aspirator or the venturi tube 11 serving as a gas-liquid mixer becomes a high-speed jet water flow due to the orifice effect, so that the so-called water tank effect occurs due to the impact effect and the pressure in the semi-sealed tank 17 increases. To do.

Therefore, the first feature of the present invention is that the pressure in the semi-enclosed tank 17 is adjusted by using the aspirator which is a gas-liquid mixer attached to the upper part of the semi-enclosed tank 17 and the water tank effect by the jet water flow ejected from the Venturi tube 11. Further, the gas-liquid mixed flow is crushed by the collision plate 111, and the pressure drop in the tank 17 is prevented by the effect of restricting the discharge flow rate of the collision plate 111, and the gas-liquid mixing effect is increased by making the microbubbles finer. Then, the increased pressure in the semi-sealed tank 17 is used to improve the solubility of the gas microbubbles in the liquid, and the liquid in which many gases discharged from the semi-sealed tank 17 are dissolved is provided downstream of the discharge port 112. It was ejected from the provided ejection nozzle 116, and it was confirmed that a fine microbubble can be generated by precipitating the gas as if it were a cider from the liquid in which the gas was dissolved.

There are almost no microbubbles in the semi-sealed tank 17, and there is a liquid in which many gases are dissolved. This gas is molecular and dissolved in the liquid, and since the pressure is reduced when ejected from the ejection nozzle 116 provided downstream of the discharge port 112, the gas is deposited like a cider. Therefore, extremely fine bubbles can be generated. The above is a big difference between the comparative example 1 and the example 1 of FIG.

As described again, a microbubble having a large diameter is generated in the tank 106 of Comparative Example 1, and is discharged through the discharge port 108. Observing that a transparent window is actually being attached to the wall surface of the tank 106 of Comparative Example 1, it can be seen that microbubbles having a large diameter are always present in the tank 106.
However, in the first embodiment shown in FIG. 1, although microbubbles are transiently generated in the tank 17, the pressure in the tank is high, so that the liquid is dissolved in the liquid immediately and many gases are dissolved in the tank 17. There is always at all times.
This can be confirmed by observing a transparent window attached to the wall surface of the tank 17.

The second feature of the present invention is the collision plate 111 provided in the vicinity of the liquid discharge port 112 to the outside of the semi-sealed tank of FIG. The collision plate 111 crushes the gas-liquid mixed flow that collides with the collision plate 111 to further refine the microbubbles. Another role of the collision plate 111 is to crush the gas-liquid mixed flow that has collided and limit the flow rate of the gas-liquid mixed flow discharged from the fluid discharge port 112 of the tank so that the pressure in the tank is below a certain value. It also has a role to prevent the deterioration. This is because the collision plate 111 is provided in the vicinity immediately above the liquid discharge port 112, so that the flow rate of the gas-liquid mixed flow discharged from the liquid discharge port 112 can be limited. The degree of restriction of the flow rate can be freely changed by changing the distance of the gap between the liquid discharge port 112 and the collision plate 111. This is a feature of the collision plate 111 of the present invention.
For this reason, the tank of the present invention is referred to as a “semi-sealed tank”.

However, as an example of a collision plate used in a conventional microbubble generator, there is a collision plate 1013 shown in FIG.
The collision plate 1013 is a collision plate used in the tank 106, and is provided immediately below the liquid surface 1014. As in the present invention, the collision plate 1013 is a gas-liquid mixed flow discharged from the tank. There is no effect of restricting the flow rate, and therefore there is no effect of keeping the pressure in the tank 106 below a certain value. This is the difference between the collision plate 111 of the present invention shown in FIG. 1 and the conventional collision plate 1013 of FIG.
That is, since the collision plate 111 of the present invention shown in FIG. 1 is provided in the vicinity immediately above the liquid discharge port 112, the flow rate of the liquid discharged from the liquid discharge port 112 is limited to some extent by the collision plate 111, and the semi-sealed tank The pressure in 17 does not drop below a certain value, and the gas solubility in the semi-sealed tank increases due to the effect of the collision plate 111. However, since the collision plate 1013 in FIG. 20 does not have the effect of limiting the flow rate of the liquid discharged from the liquid discharge port 108 unlike the collision plate 111, the pressure in the tank 106 in FIG. It is much lower than the pressure in the semi-sealed tank 17. This is the difference between the present invention of FIG. 1 and the conventional apparatus shown in FIG.

Further, FIG. 32 shows the aspirator 11 used in FIG. The rectifying pipe 3206 provided at the liquid inlet of the aspirator according to the present invention is characterized in that a plurality of holes 3213 in the rectifying pipe 3206 are twisted and formed.
For this reason, the liquid flow ejected from the aspirator becomes a liquid flow drawing a spiral with each other, and the gas from the gas inlet 3208 is sufficiently entrained to improve the gas-liquid mixing efficiency.

  An aspirator itself having a rectifying tube with a plurality of holes that are twisted and pierced with each other has been known for more than 30 years, and has been used as an aspirator for more than 30 years. MS-1 from Tokyo Glass Instrument KK is typical.

In addition, a patent using an aspirator having a plurality of rectifying pipes having a plurality of holes twisted and drilled as described above as an ejection nozzle for a free liquid tank under atmospheric pressure is disclosed in Japanese Patent No. 3264714 (November 14, 1992). (Japanese application) “Bubble generator”.

However, since this patent uses an aspirator as a jet nozzle into a free water tank under atmospheric pressure, a jet gas-liquid mixture jetted from an aspirator or a venturi tube is jetted into a semi-enclosed tank as in the present invention. Therefore, the water tank effect increases the pressure in the semi-sealed tank and does not improve the gas solubility. Moreover, if the liquid flow that draws a spiral from the aspirator is discharged into a free liquid tank under atmospheric pressure, the liquid flow drawing the spiral is diffused by centrifugal force, so the effect of mixing the gas and liquid is diminished. Mixing efficiency decreases.
However, when the liquid flows drawing a spiral are injected into a semi-sealed tank having a pressure higher than the atmospheric pressure, the liquid flows drawing a spiral do not diffuse due to centrifugal force, and the liquid flow drawing a spiral contracts due to the pressure in the tank. However, the gas-liquid in the liquid flow that draws a spiral is well mixed, and the gas is easily dissolved in the liquid. Fine microbubbles can be obtained by colliding a liquid flow that draws a spiral in which gas is well dissolved against the collision plate.
In addition, even if liquid flows that are parallel to each other without drawing a spiral are used, the same effect can be obtained to some extent by omitting the rectifier tube and using a liquid flow having a single streamline. It can be considered that the embodiment is the same as the embodiment having a straight hole.

Therefore, the aspirator or the venturi tube of the present invention is completely different from the aspirator used in Japanese Patent No. 3264714.

Further, a fourth feature of the present invention is shown in FIG. A liquid in which a large amount of gas discharged from a semi-sealed tank (not shown) is dissolved is led to the second venturi pipe or aspirator 3701, and at least a hose connected to at least the gas inlet 3705 is connected to the second venturi pipe or aspirator 3701. Immerse it in a free liquid tank under atmospheric pressure or immerse the entire venturi pipe or aspirator 3701, and let the fine bubbles in the free liquid tank self-suck from the gas inlet 3705 of the second venturi pipe or aspirator 3701. The sucked fine bubbles are further refined and discharged by the orifice in the second venturi tube or aspirator 3701.
Since this cycle is repeated endlessly, it was confirmed that the fine bubbles in the free water tank rapidly increased in concentration and could be further refined.

The fifth feature of the present invention is shown in FIG. A liquid in which many gases discharged from a semi-sealed tank (not shown) are dissolved is guided to the second venturi pipe or aspirator 3801, and the second venturi pipe or aspirator 3801 is not necessarily immersed in a free liquid tank under atmospheric pressure. A part of the gas-liquid mixed flow immediately before being ejected from the gas-liquid mixed outlet of the second venturi tube or aspirator 3801 is self-primed from the gas inlet 3805.
The self-primed fine bubbles are further refined by the orifice in the second venturi tube or aspirator 3801 and discharged.
Since this cycle is repeated endlessly, it was confirmed that the fine bubbles in the free liquid tank rapidly increased in concentration and could be further refined.
At this time, since the liquid containing impurities existing in the free liquid tank is not sucked, a new gas-liquid mixed flow is always supplied to the second venturi tube or the aspirator 3801 and the impurities are not clogged.

Returning to the description of the first embodiment shown in FIG.
In FIG. 1, when liquid (dissolving water) in which gas is dissolved is supplied from the liquid discharge port 112 to the shower head 114 via the hose 113, liquid is ejected from the outlet 116 of the shower head 114. At this time, the pressure of the liquid approaches the atmospheric pressure and decreases immediately before the outlet 116, so that the gas dissolved in the liquid becomes microbubbles and precipitates in the liquid.
Reference numeral 115 denotes a flow rate adjusting valve provided in the shower head 114.
When the flow regulating valve 115 is fully opened, the pressure drop is too rapid, so that the generation of microbubbles is relatively small, and low-concentration type microbubbles and a large excess of millibubbles are generated. When the flow control valve 115 is not fully opened but is throttled to some extent, the degree of pressure drop is appropriate, and the liquid (water) coming out from the outlet 116 of the shower head 114 is a medium-concentration type or high-concentration type microbubble. It became cloudy and it was confirmed that 10 to 50 μ microbubbles were generated. (Non-Patent Document 1)
The number of high-concentration type microbubbles is several thousand / mL, and the number of low-concentration type microbubbles is several hundred / mL. This number meets the criteria for high-concentration type and low-concentration type microbubbles shown in P.4 of Non-Patent Document 1 “Latest Microbubble Technology”. It was confirmed that the microbubble generator can generate any of the bubbles.

Also, when the capacity of the semi-sealed tank is around 1 liter and the water pressure of the water supply is about 2 kgf / square centimeter, after the state where the flow control valve 115 has been throttled to some extent for more than 10 minutes, Since it is completely filled with liquid and gas can no longer be self-primed from the venturi or aspirator, less gas is dissolved in the semi-sealed tank and gas microbubble generation begins to decline.
Therefore, if the flow control valve 115 is fully opened every 10 minutes for about 4 seconds, the liquid in the semi-sealed tank can be discharged and the liquid can be prevented from filling up in the semi-sealed tank, and the gas self-priming starts again. Can generate microbubbles.
Repeating the above cycle can permanently generate microbubbles.

Further, in the industrial / agricultural microbubble generating apparatus, a drain needle valve 3006 shown in FIG. If the part is discharged from the draining needle valve 3006 as indicated by an arrow 3007, the liquid flow discharged from the semi-sealed tank increases and the tank can be prevented from being filled with liquid.
If such a drain / parallel needle valve 3006 is provided, microbubbles can be generated permanently. The same applies to FIG. 37 provided with a similar drainage needle valve (not shown).
The diameter of the microbubble was determined by measuring the rising speed of the microbubble according to Stokes' law.
The lifting speed of air microbubbles with a diameter of 20 μm in water is 0.05 mm / second.
A check valve 13 provided at the liquid inlet 12 prevents the gas-liquid mixed flow from flowing back to the water supply when the pressure in the semi-sealed tank increases, and increases the pressure in the semi-sealed tank by the water tank effect. Has the effect of causing
The check valve 15 provided at the gas inlet 14 has an effect of preventing the gas-liquid mixed flow from flowing backward to the gas inlet when the pressure in the semi-sealed tank increases.
The check valve 13 can be omitted depending on the water pressure of the water supply 118.
However, the check valve 15 provided at the gas inlet 14 cannot be omitted.

"The latest technology of microbubbles" Publisher: NTT Co., Ltd. Author: Masayoshi Takahashi (National Institute of Advanced Industrial Science and Technology, Senior Researcher) The citation is described below from page 4 above; There are two types of bubble generators: a high-concentration type and a low-concentration type, which can measure the bubble distribution in real time by using a kind of in-liquid particle counter. 15 μm is the central particle size and the concentration is several thousand pieces / mL.The low concentration type has a diameter of 20 to 40 μm and the central particle size is several hundred pieces / mL.In appearance, the high concentration type is like milk The low-concentration type is a little cloudy, and the apparent whiteness reflects the state of bubbles, so a device that discharges clear water is an excellent microbubble generator. However, add salt and surfactant. That if, appearance tends to be white situation, many may not be said to be micro-bubble. "

As described on page 4 above, the microbubbles of the microbubble generator of the present invention are white microbubbles such as milk as shown in the actual photograph using only water shown in FIG. Therefore, it did not float very fast like ordinary millibubbles and could not be played on the surface of the water, and ascending speed according to Stokes' law was observed as described above. Thus, the microbubble generator of the present invention belongs to a high concentration type microbubble generator.
FIG. 22 is an actual photograph in which the microbubble generator shown in Example 1 of the present invention is applied to a bath shower apparatus. The size of the semi-sealed tank in the photograph is 90 mm in outer diameter and 150 mm in height, and the actual photograph of the microbubbles generated from this microbubble generator is the photograph in FIG.

Comparison between Comparative Example 1 shown in FIG. 20 and Example 1 shown in FIG. 1 will describe the effect of the present invention.
In Comparative Example 1, the negative pressure generated on the suction side of the electric pump 101 when the water (hot water) from the bathtub 1010 is sucked by the electric pump 101, and the gas (air) is sucked from the gas inlet 103 using the venturi 102. is doing.
Therefore, even if the pressure in the tank 106 increases, the gas-liquid mixed flow does not flow backward from the injection nozzle 107 toward the hose 105. Therefore, the gas inlet 103 has an advantage that it is not necessary to provide a check valve. In the case of a microbubble generator for a bath, which requires a half-surface electric pump 101, there is a risk of electric shock or leakage if a commercial power source is pulled into the bathroom.

The apparatus of Example 1 in FIG. 1 generates microbubbles using only water pressure, and does not circulate water (hot water) in the bathtub as in Comparative Example 1 in FIG. Hot water) is used, so that clogging due to dirt does not occur, and maintenance of the apparatus is unnecessary.
When the apparatus of Example 1 is used as an apparatus for generating microbubbles in a bathtub without using it as a shower, only 60% of water is placed in the bathtub in advance, and the water is heated to 38 ° C. in a bath tub, and then a water heater When the shower head 116 of the apparatus connected to the first embodiment is put in the bathtub and microbubbles of hot water are generated in the bathtub to enter the bathtub, the hot water in the bathtub becomes a temperature suitable for bathing and the amount of water used is increased. You don't have to.
In addition, since microbubbles of new water are always added to the bathtub, there is no clogging as when circulating and no electricity is used, which saves energy.

Since microbubble generators other than those for bathing are also used around water, it is important not to use electricity again because there is no risk of leakage or electric shock. In addition, all that can be completed with only water pressure makes the equipment simple, not just a shower for baths, a bathtub, but oil and water separation, aquatic sacrifice, plant cultivation, washing machine, dishwasher, oral washer, drinking water generator The present invention is also effective for flush toilets, water purification devices, car wash devices, and the like.
However, in the microbubble generating apparatus used for industrial and agricultural purposes, water charges can be saved by using well water by pumping up well water, so an electric pump for well water may be used. Although the well water electric pump uses electricity, if it is handled like the water pump of the Waterworks Bureau, it can be regarded in the same way as the above-mentioned microbubble generator using only water pressure.

Also, the liquid inlet of the apparatus of the present invention similar to the embodiment 1 of FIG. 1 is not connected to the water supply, but is connected to the discharge port of a pump (not shown), and the liquid discharged from the apparatus of the present invention and accumulated in the liquid tank is supplied to the pump. It is also possible to suck from the suction port, and supply and circulate again to the liquid inlet through the pump. At this time, in order to prevent clogging, the diameter of the orifice inside the aspirator or venturi which is the gas-liquid mixer of the apparatus of the present invention is increased, the gas-liquid mixer is paralleled, and the gas flowing into the gas inlet May be pumped using a gas pump or a cylinder (not shown).

  Examples of the present invention will be described.

  Example 1 has already been described above in conjunction with FIG.

As a second embodiment, as shown in FIG. 2, a venturi tube or aspirator 21 in which a check valve is provided in each of the gas inlet 24 and the liquid inlet 22 is used. A check valve 23 may be provided at the liquid (water) inlet 22 of the venturi tube or aspirator 21. A check valve 25 is also provided at the gas inlet 24.
The liquid (water) flowing from the water supply 218 through the hose 217 flows into the liquid inlet 22 through the check valve 23 and passes through the narrow diameter portion of the venturi pipe or the aspirator 21, so that the pressure of the fluid decreases. Therefore, the gas (air) is self-absorbed from the gas inlet 24, and the gas (air) and the liquid (water) are mixed in the venturi tube or the aspirator 21 to form a gas-liquid mixed flow, and the gas-liquid mixing / semi-sealing The gas-liquid mixed flow is injected from the lower part of the tank 27 toward the inner ceiling of the semi-sealed tank 27 through the injection hole 26, and the gas-liquid mixed flow collides with the inner ceiling of the semi-sealed tank 27, whereby the gas-liquid mixed flow is stirred. . And since the pressure in the semi-sealed tank increases, the gas (air) 28 is dissolved in the liquid (water) 210.
Reference numeral 211 denotes a collision plate provided in the vicinity immediately above the liquid discharge port 212 provided at the bottom of the gas-liquid mixing / semi-sealed tank 27.
The collision plate 211 limits the flow rate of the liquid (water) 210 exiting from the gas-liquid mixing / semi-enclosed tank 27, and the pressure in the gas-liquid mixing / semi-enclosed tank 27 is maintained above a certain level. ) The gas (air) 28 is dissolved in 210. Not only that, the action of the collision plate 211 makes it difficult for large gas bubbles to come out to the liquid discharge port 212.

When the liquid (water dissolving the air) dissolving the gas is supplied from the liquid discharge port 212 to the shower head 214 via the hose 213, the liquid is ejected from the outlet 216 of the shower head 214. At this time, since the pressure of the liquid is close to the atmospheric pressure and decreases immediately before the outlet 216, the gas dissolved in the liquid becomes microbubbles and precipitates in the liquid.
Reference numeral 215 denotes a flow rate adjusting valve provided in the shower head 214.
The function of the check valve 23 is to prevent the gas-liquid mixed flow from flowing backward from the semi-hermetic tank 27 toward the hose 217 when the internal pressure of the gas-liquid mixing / semi-hermetic tank 27 increases. The check valve 23 can be omitted depending on the water pressure of the water supply 218.
The function of the check valve 25 is to prevent the gas-liquid mixed flow from flowing backward from the semi-sealed tank 27 through the gas inlet 24 into the atmosphere when the internal pressure of the gas-liquid mixing / semi-sealed tank 27 increases. Therefore, the check valve 25 cannot be omitted.
The reason why microbubbles are used in the bath shower is that the microbubbles have a dirt cleaning effect. (Non-patent document 6)
When using this equipment with hot water from a gas water heater with a mixing tap for bath, a mixing tap with a check valve must be used.
The gas water heater must also have a check valve, and the electric water heater should not be used because the water pressure is weak. Also, the shower head with the flow control valve 215 must not be able to completely shut off the water flow. If the flow control valve 215 is not a leaking water flow type / shower with a flow control valve, a small amount of water flows even when the flow control valve 215 is at the stop position. Don't be. The level of the leaked water flow from which a small amount of water flows is the level of the leaked water flow that blows up to a height of about 10 cm or more when the water flow of the shower head 214 is directed upward. If for any reason the water does not blow up to a height of about 10 cm or more, use must be stopped immediately. Otherwise, the internal pressure of the semi-sealed tank 27 may increase too much, and the tank may burst or break, the hoses connected to the tank may burst, or the screw part may come off, resulting in an accident.
Also, if the water flow does not blow up to a height of about 10 cm or more due to some reason, the internal pressure of the semi-sealed tank 27 increases and the mixing faucet connected to the semi-sealed tank 27 In the case of mixing with hot water, some types of mixed taps may cause a back flow to the water heater and cause trouble.
For this reason, in the apparatus of the present invention, any type of mixing faucet must be used in such a state that only hot water is discharged and water is not mixed. Or it must be used only in water. The same applies to the embodiment of FIG. This is not limited to the apparatus of the present invention, and is the same as common sense for all devices that supply only water pressure.

If the water flow of the leaking water flow type / shower head with flow control valve is completely interrupted due to some reason, this device should not be used. Replace the leaking water flow type / shower head with flow control valve with a new one. There must be.

When using hot water from a gas water heater even with a mixed water tap with a check valve, set the temperature of the gas water heater to the desired temperature, and use this device to supply hot water from only the gas water heater. Used, the cold water cock must be closed. Even in the case of a mixing faucet in which the mixing ratio of hot water and cold water can be changed with one lever, the device must be used with the lever set only at the position of hot water or cold water.
When used under conditions other than those mentioned above, there may be a problem with PL, so a business operator who produces and sells the device of the present invention should thoroughly inform the user of the above.
The same applies to the embodiment of FIG.

As a third embodiment, a venturi tube or aspirator 31 provided with check valves at the gas inlet 34 and the liquid inlet 32 as shown in FIG. 3 is used. A check valve 33 is provided at the liquid (water) inlet 32 of the venturi tube or aspirator 31. A check valve 35 is also provided at the gas inlet 34.
When the liquid (water) flowing from the water supply 318 through the hose 317 passes through the check valve 33 and flows into the liquid inlet 32 and passes through the narrow diameter portion of the venturi or the aspirator 31, the pressure of the fluid decreases. Therefore, the gas (air) is self-absorbed from the gas inlet 34, and the gas (air) and the liquid (water) are mixed in the venturi tube or the aspirator 31, and become a gas-liquid mixed flow from the gas-liquid mixed outlet. The gas-liquid mixed flow is injected through the injection hole 36 toward the inner ceiling of the semi-sealed tank through the check valve 321 of the gas-liquid mixed flow inlet at the lower part of the semi-sealed tank 37, and the gas-liquid mixed flow is applied to the inner ceiling of the semi-sealed tank 37. The gas-liquid mixed flow is stirred by the collision. And since the pressure in the semi-sealed tank increases, the gas (air) 38 is dissolved in the liquid (water) 310.
Reference numeral 311 indicates a collision plate provided in front of the liquid discharge port 312 provided at the bottom of the gas-liquid mixing / semi-sealed tank 37.

A valve chamber 319 having a drain valve 320 is provided opposite to the gas-liquid mixed outlet of the venturi pipe or aspirator 31, and when the drain valve 320 is closed by the pressure of the gas-liquid mixed flow flowing into the valve chamber, Due to the impulse, the pressure of the gas-liquid mixed flow in the valve chamber 319 increases, and the gas-liquid mixed flow is injected into the semi-sealed tank 37 via the check valve 321 to increase the pressure in the semi-sealed tank. The liquid and gas in the semi-sealed tank with increased pressure do not flow back to the valve chamber 319 by the check valve 321. This principle is the principle of a known water hammer pump.

"Water hammer pump production guide book" Kenichi Kagami published by Power Co., Ltd. The water hammer pump is for pumping water, not for gas-liquid mixed flow, but it can be applied to gas-liquid mixed flow. For example, even when the water pressure of the tap water is low, the internal pressure of the semi-sealed tank 37 can be increased to several times the tap pressure without using electricity, so that more gas can be dissolved in the liquid in the semi-sealed tank. Further, a collision plate 311 is provided at the liquid discharge port to the outside of the semi-sealed tank, and the flow velocity of the gas-liquid mixed flow flowing out from the lower part of the semi-sealed tank is limited by the collision plate.

FIG. 13 shows a variation of Example 3. It is the Example which connected the exit of the drain valve 320 of the water hammer pump of FIG.

The shower head for baths to be produced can also be configured. Reference numeral 617 denotes a collision plate provided at the gas-liquid mixed outlet of the venturi tube or the aspirator 61. The collision plate 617 can be omitted. Moreover, the apparatus of Example 7 can only generate microbubbles having a lower concentration than those of Examples 1, 2 and 3 using a semi-sealed tank.

As an eighth embodiment, a liquid inlet of an apparatus for generating gaseous microbubbles in a liquid or an inlet of a check valve provided at the liquid inlet is connected to water, and water from the water is used as the liquid. When the gas passes through the venturi tube or the aspirator through the check valve, air is sucked from the gas inlet of the venturi tube or the aspirator, and the gas microbubbles are put into the liquid. A collision plate is provided at the liquid outlet to the outside of the semi-sealed tank of the device to be generated, and the flow velocity of the gas-liquid mixed flow exiting from the lower half of the semi-sealed tank is limited by the collision plate, and the flow velocity is limited by the collision plate.

As Example 9, as shown in FIG. 7, the apparatus is downsized, the faucet 70 is accommodated in the faucet 70, the faucet 70 is connected to the water supply, and the reverse provided in the liquid outlet 72 of the stop cock 715 of the faucet 70. When the liquid flowing in through the stop valve 73 passes through the venturi pipe or aspirator 71, air is self-primed from the gas inlet 74 of the venturi pipe or aspirator 71, and the venturi pipe Alternatively, a collision plate 711 is provided at the liquid discharge port of the semi-sealed tank 77 in the faucet provided at the outlet of the aspirator to the outside of the semi-sealed tank so that the flow velocity of the gas-liquid mixed flow flowing out from the semi-sealed tank 77 can be reduced.

Here, the gas-liquid mixing outlet 806 of the gas-liquid mixing pipe 801 such as an aspirator or a venturi pipe is connected to the semi-sealed tank 805 to inject the gas-liquid mixed flow into the semi-sealed tank 805. A gas-liquid mixing tube 803 is also connected downstream of the liquid mixing outlet 807, the gas-liquid mixing flow in the semi-sealed tank is guided to the gas-liquid mixing tube 803, and the gas from the gas inlet 808 is again sent to the gas-liquid mixing tube 803.

As Example 21, as shown in FIG. 19, a car wash device characterized by using microbubble water generated by the device for car wash water such as a vehicle can be configured. (Non-patent document 6)

As Example 22, a check valve was attached only to the gas inlet of the venturi tube or the aspirator, and the check valve attached to the liquid inlet was omitted, depending on the liquid pressure at the liquid inlet or the water outlet water pressure. An apparatus that generates microbubbles in a liquid can also be configured.

In addition, each device in Example 10 to Example 22 is a gas-liquid mixed flow containing microbubbles exiting from the liquid outlet to the outside of the semi-sealed tank of Example 1 to Example 5. It can comprise by supplying to the microbubble water supply port of each apparatus in 22.

Further, in common with all of the above embodiments, water or hot water from the tap water may be used as a liquid supply source, and the liquid or hot water may be disposable without being circulated. Also, for example, in the case of a bathtub, a certain amount of water from the tap is stored in the bathtub, and a certain amount of water or hot water stored in the bathtub is sucked up from the bathtub and circulated using a pump similar to the electric pump 101 in FIG. The gas-liquid mixing / semi-enclosed tank of the above embodiment is supplied using a venturi tube or an aspirator, and the pressure in the semi-enclosed tank is used to dissolve the gas in the liquid. To generate microbubbles.

In addition, the gas may be a gas containing at least one of air, chlorine, ammonia, nitric oxide, carbon dioxide gas, ozone, hydrogen, oxygen, bromine, and sulfurous acid gas in common to all the above embodiments.
These gases supplied to the gas inlet are pumped by a known gas pump (not shown), gas in a cylinder (not shown), or gas generated from a chemical reaction tank (not shown) is supplied. You can also. For example, carbon dioxide can be generated by adding water to quicklime, but can also be generated by adding water to sodium bicarbonate.
Chlorine can also be generated from crawl chalk. Hydrogen can also be generated by reacting organic and inorganic acids with metals. Ozone can be generated using a known ozone generator. Oxygen can also be generated using a known oxygen concentrator. All known gas generation methods (not shown) use known methods.

When gas microbubbles are generated in a liquid, the gas dissolution efficiency is dramatically improved by the microbubbles and the huge total surface area.
In the so-called aeration in which the same gas is supplied in the form of millibubbles or centimeter bubbles, the gas in the bubbles escapes from the liquid surface, and the gas does not reach the saturation solubility in the liquid unless it is aerated for a long time. Until then, many gases have escaped from the liquid surface, and the gas utilization efficiency is extremely poor.
However, when microbubbles are used, the gas dissolves in the liquid very quickly and the utilization efficiency of the gas is very high.
For example, when air is aerated, the air can be dissolved at 9 mg / L for the first time after aeration for 30 hours, whereas when microbubbles are injected, the same air can be dissolved in only 4 hours. (Non-patent document 6)

It is obvious that by generating these gas microbubbles and supplying them to the chemical reaction tank, the gas can be dissolved in the liquid much faster than simple aeration.
The liquid contains water, acid, alkali (for example, potassium hydroxide), or an organic solvent, and the air, chlorine, ammonia, nitric oxide, carbon dioxide, ozone, hydrogen, oxygen, It is also possible to inject a microbubble containing a gas such as bromine or sulfurous acid gas to form a chemical reaction tank that quickly performs a gas-liquid reaction. (Non-patent document 6)
In addition, when microbubbles of air are generated in water containing potassium hydroxide or ultra-alkaline ion water, it can be used as an industrial cleaning device because it can dissolve and remove oil from machine parts contaminated with oil. .

In the case of ozone, its sterilizing power and deodorizing power can be used, and in the case of carbon dioxide, it can also be used as carbon dioxide rich water supplied to plants. In the case of air, it can also be used as oxygen-rich water supplied to plants. In the case where the gas is hydrogen, hydrogen-rich water in which hydrogen is dissolved is produced, so that it can be used as drinking water, cosmetic lotion, water for suppressing cancer cell growth, and the like.

Recently, when cancer cells are cultured in hydrogen-rich water, experimental results have shown that the growth of cancer cells is lower than that of normal water. (Non-patent document 3, Non-patent document 4) However, when the liquid generated from this apparatus is used for a human body or an animal, it must be approved by the Pharmaceutical Affairs Law.

When air, carbon dioxide, hydrogen, ozone, or other gas is generated in water as microbubbles, it floats slowly while shrinking in water due to the strength of the surface tension of the bubbles, which is the nature of gas microbubbles. The so-called hot spot is formed. And it is known that gas converged on one point is expelled explosively and dissolved in water. (Non-Patent Document 5)
Compared to this, conventional millibubbles and centimeter bubbles rise while rapidly expanding, hop on the surface of the water, and released into the atmosphere, so the gas dissolution effect is extremely small.
In addition, when making microbubbles, such as ozone, a carbon dioxide, hydrogen, etc. other than air, well-known ozone generators, a carbon dioxide cylinder, a hydrogen cylinder, or a hydrogen generator etc. which are not shown in figure are shown in FIG.1, FIG.2, FIG.3. What is necessary is just to connect to the check valves 15, 25, 35 of the inflow ports 14, 24, 34.

FIG. 23 shows an embodiment 23 of the aspirator. When liquid is injected from the liquid inlet 2301 of the aspirator and injected into the receiving pipe 2304 through the rectifying pipe 2308 in the nozzle 2303, the gas flowing in from the check valve 2306 passes through the gas inlet 2305 and passes through the nozzle. The air is sucked from the gap between 2303 and the receiving pipe 2304, sent to the mixing pipe 2307, gas-liquid mixed, and discharged from the gas-liquid mixing outlet 2302.

FIG. 24 shows an embodiment 24 of the venturi tube. Since liquid is injected from the liquid inlet 2401 of the venturi tube 2406 and passes through the constriction 2403, the pressure is reduced, so that the gas flowing in from the check valve 2405 passes through the gas inlet 2404 and is sucked into the constriction 2403. It is sent to the mixing tube 2406 to be gas-liquid mixed and discharged from the gas-liquid mixing outlet 2402.

FIG. 25 shows a twenty-fifth embodiment of a venturi tube. Since the liquid is injected from the liquid inlet 2501 of the venturi tube 2506 and is reduced in pressure when passing through the constriction 2503, the gas flowing in from the check valve 2505 passes through the gas inlet 2504 provided immediately downstream of the constriction 2503. Passed and sucked, sent to the mixing tube 2506, gas-liquid mixed, and discharged from the gas-liquid mixing outlet 2502. The gas inlet 2504 provided immediately downstream of the constriction 2503 is also under reduced pressure.

FIG. 26 shows check valves used in all the examples. When the gas is sucked from the gas inlet 2601 of the check valve 2605, the spring 2604 is pushed and contracts, the gas stopper 2603 moves downward, the gas flows as shown by an arrow 2602, and is sent to a gas inlet (not shown). .
FIG. 26 (a) shows the above state, and FIG. 26 (b) shows a state where the gas stopper 2603 moves upward when the gas inlet (not shown) has a high atmospheric pressure, and the backflow of gas is prevented. An arrow 2602 is a gas flow.
The check valve that can be used in all the embodiments is not limited to the check valve shown in FIG. 26, and is a known check valve in which a stainless steel ball (not shown) blocks the tapered gas inlet and prevents the reverse flow. It is obvious that it is good.

FIG. 27 is an embodiment showing a semi-hermetic tank 2703 that can be used in all embodiments.
When the gas-liquid mixed flow is injected into the semi-sealed tank 2703 from the wall surface of the semi-hermetic tank 2703, if the gas-liquid mixed outlet 2701 is provided at a position away from the center of the semi-hermetic tank 2703, the gas-liquid mixed flow is a vortex 2704. In this way, it flows along the inner wall surface of the semi-hermetic tank 2703 while swirling. For this reason, the center of the vortex has a negative pressure, and the gas in the gas-liquid mixed flow becomes fine bubbles and is deposited at the center of the vortex and is discharged from the gas-liquid mixed outlet 2702 of the semi-sealed tank. The collision plate is 2711.

FIG. 28 shows a twenty-eighth embodiment. FIG. 28 shows an example of a semi-sealed tank 2803 that can be used in all the examples.
When the gas-liquid mixed flow is injected into the semi-sealed tank 2803 from the wall surface of the semi-sealed tank 2803, if the gas-liquid mixed outlet 2801 is provided at a position away from the center of the semi-sealed tank 2803, the gas-liquid mixed flow is a vortex 2804. In this way, it flows along the inner wall surface of the semi-hermetic tank 2803 while swirling. For this reason, the center of the vortex becomes negative pressure, and the gas in the gas-liquid mixed flow becomes fine bubbles and deposits at the center of the vortex and is discharged from the gas-liquid mixed outlet 2802 of the semi-sealed tank. The collision plate is 2811.
Here, instead of providing the gas-liquid mixture outlet 2801 at a position away from the center of the semi-sealed tank 2803, the gas-liquid mixed stream can be injected into the semi-sealed tank from the center position of the semi-sealed tank indicated by reference numeral 2806. At this time, the gas-liquid mixed flow is discharged from the gas-liquid mixed outlet 2802 while winding the vortex 2804 by the force of Coriolis.
For this reason, the center of the vortex becomes negative pressure, and the gas in the gas-liquid mixed flow becomes fine bubbles and precipitates at the center of the vortex. However, since the negative pressure is not as large as in Example 27, the diameter and number of fine bubbles are Slightly less than Example 27. The diameter and number of microbubbles will also vary depending on the capacity, diameter and height of the semi-closed tank.

FIG. 29 shows the structure of a cylindrical sprinkler tap that can be used at the gas-liquid mixing outlet of the gas-liquid mixing tube used in common in all the embodiments.
The gas-liquid mixed flow 2901 passes through the center of the inner pipe 2902 of the water spigot, passes through the hole 2904 in the inner pipe wall surface provided downstream of the inner pipe 2902, and goes to the outer pipe 2907 outside the inner pipe 2902. It passes through a gap 2902 between the tube 2902 and the outer tube 2907 and collides with a conical collision body 2906 to be ejected as a fine jet 2905.
At this time, when the outer tube 2907 is rotated in the direction of the arrow 2909, the outer tube 2907 rotates according to the pitch of the screws 2910. As a result, the relative position of the collision body 2906 between the outer tube 2907 and the inner tube 2902 changes, and the state of the jet 2905 changes, resulting in a dome-like jet or a direct jet.
If such a water spigot is provided at the gas-liquid mixing outlet of the gas-liquid mixing tube and sprayed into the semi-sealed tank, the state of gas-liquid mixing can be varied. The relative position between the inner tube 2902 and the outer tube 2907 may be rotated by rotating the dial 2908.

The photograph in Fig. 42 shows the fact that the fabric cannot be dyed unless the paste / polyvinyl alcohol (PVA) remaining on the fabric is cleaned / removed. It is a photograph which shows the state of the water after washing | cleaning.
As shown in the photo, a lot of polyvinyl alcohol floated on the surface of the water, and it was confirmed that it was well cleaned and removed.
This polyvinyl alcohol was tested using NP-05F · PVA manufactured by Denka KK, which is most often used in textile factories. NP-05F / PVA dissolves in water only at 60 ° C. or higher, so that a certain amount of water dissolved in water at 60 ° C. or higher is infiltrated into cotton, and then the dried cloth is washed with microbubble water at 25 ° C. did.
However, at 25 ° C., NP-05F · PVA should not dissolve, but it was eluted in large quantities by microbubbles. This is an experimental result showing how great the microbubble surface active effect of this device is.

FIG. 43 shows a photograph of washing cotton impregnated with NP-05F · PVA with the same water pressure as in FIG. 42 using only tap water without using microbubble water.
As shown in the photograph, it was confirmed that the washing water was transparent and NP-05F · PVA was not eluted.

FIG. 31 shows a new aspirator having a variable structure that can be commonly used in all the embodiments.
When the liquid is injected from the liquid inlet 3101 of the aspirator and injected into the receiving pipe 3105 through the rectifying pipe 3106 in the liquid jet nozzle 3103, the inflowing gas passes through the gas inlet 3108 and passes through the nozzle tip 3104. And the receiving pipe 3105 are sucked from the gap and sent to the mixing pipe 3109 to be gas-liquid mixed and discharged from the gas-liquid mixing outlet 3102. When the liquid ejection nozzle 3103 is rotated in the circumferential direction, the relative position between the liquid ejection nozzle 3103 and the outer tube 3113 is changed by a screw 3107 provided on the outer wall of the liquid ejection nozzle 3103, and the gap between the nozzle tip 3104 and the receiving tube 3105 is changed. Can be changed. A screw 3111 is provided on the outer periphery of the liquid ejection nozzle 3103, and the position of the liquid ejection nozzle 3103 can be fixed by tightening the nut 3112.
In this way, the amount of gas to be gas-liquid mixed can be varied, so that the diameter and number of microbubbles can be varied.

FIG. 31B is an enlarged top view of the rectifying tube 3106 viewed from the top. The rectifying tube 3106 is originally a cylindrical block, and has three or four holes 3110 in the length direction of the cylinder. Here, an example of three holes 3110 is shown.
The holes 3110 may be formed along the length direction of the cylindrical block, or the three holes may be formed by twisting each other. When twisted apart, the liquid flow swirls toward the nozzle tip 3104 and mixes well with the aspirated gas in the receiving tube 3105. At this time, the generation of negative pressure is large, and a large amount of gas is sucked from the gas inlet 3108. Therefore, the diameter of the microbubbles increases and the number increases.
When the three holes 3110 are not twisted with respect to each other and are made parallel to the length direction of the liquid ejection nozzle 3103, the swirling of the liquid is not so large and the negative pressure is relatively small, so the diameter and number of microbubbles are small. I know.
A rectifying tube similar to the rectifying tube 3106 can also be used upstream of the gas-liquid mixing tube, that is, the nozzle of the aspirator or the venturi tube, or the constriction in all the embodiments.

FIG. 32 (a) shows an example of an aspirator used in this apparatus. The liquid flow that has passed through the plurality of holes 3210 in the rectifying pipe 3206 passes through the liquid ejection nozzle 3204 and is mixed with the gas that has flowed in from the gas inlet 3208 in the receiving pipe 3205 to form a gas-liquid mixed flow. The plurality of holes 3210 in the rectifying pipe 3206 may be drilled in parallel with each other like the hole 3210 in FIG. 32B, or may be twisted with each other like the hole 3213. If the rectifying tube 3206 is omitted, the liquid becomes a single streamline without twisting. However, this still has a certain gas-liquid mixing effect, so the rectifying tube 3206 may be omitted depending on the flow rate. If the rectifying pipe 3206 is omitted, it is obvious that the single liquid flow that can be generated is the same as the single liquid flow in the case of using the rectifying pipe having one large hole without twisting.

  In FIG. 33, an aspirator 3312 is attached to the upper part of the semi-sealed tank 3317, and the gas-liquid mixed flow ejected from the gas-liquid mixed outlet of the aspirator 3312 collides with a collision plate 3311 provided immediately above the discharge port at the lower part of the semi-sealed tank. It is the figure made to become a fine microbubble. The collision plate 3311 also has a role of keeping the internal pressure of the semi-sealed tank at a certain level or more because it restricts the discharge speed of the gas-liquid mixed flow.

  FIG. 34 shows an embodiment in which a gas-liquid mixed flow ejected from an aspirator 3412 attached to the upper part of the semi-sealed tank is collided with a collision plate 3411 provided immediately above the discharge port at the lower part of the semi-sealed tank to form fine microbubbles. The collision plate 3411 is doubled, the upper portion is a fine mesh plate, and the lower portion is made of a plate made of plastic or metal. There is a gap of several mm between the two collision plates. If it does in this way, the gas-liquid mixed flow which collided with the upper net | network board will be crushed with a net | network plate, will collide with the board below a net | network board, and will become a finer microbubble.

FIG. 35 shows an embodiment in which a gas-liquid mixed flow ejected from an aspirator 3512 attached to the upper part of the semi-sealed tank is collided with a collision plate 3511 provided immediately above the discharge port at the lower part of the semi-sealed tank to form fine microbubbles. The collision plate 3511 is a conical or pyramidal collision plate. In this way, the gas-liquid mixed stream is well stirred.

FIG. 36 shows a sketch of the collision plate 3311 used in FIG. Reference numeral 3611 denotes a collision plate.

FIG. 37A shows a Venturi tube 3701. The gas inlet of the venturi tube is 3705.
In FIG. 37 (b), in which at least the gas inlet is immersed in the liquid tank in the Venturi tube 3701, the microbubbles contained in the gas-liquid mixed flow ejected from the gas-liquid mixed outlet of the Venturi tube 3701 as indicated by the arrows are It is naturally sucked by 3705 which is a gas inflow port, and again passes through the narrowed portion of the Venturi tube 3701 to become finer microbubbles.
Here, only a hose (not shown) connected to the gas inlet 3705 may be immersed in the liquid tank. In this way, the same effect can be obtained as when the entire venturi tube 3701 is immersed as shown in FIG.
Since this cycle is repeated endlessly, the microbubbles in the liquid tank rapidly become highly concentrated, and the effect of cleaning an object to be cleaned in the liquid tank is increased.
The cleaning effect of the above-mentioned residual textile paste / PVA was also measured using the embodiment shown in FIG. The photograph is the photograph of FIG.
The venturi tube 3701 of FIG. 37 (a) can also be replaced by the aspirator shown in FIG.
Further, the gas / liquid mixed flow supplied to the liquid inlet of the venturi tube or the aspirator may be a gas / liquid mixed flow discharged from the semi-sealed tank of the present invention, or a gas / liquid generated from a known microbubble generating device (not shown). A mixed stream may be supplied.

FIG. 38 shows another embodiment different from FIG.
A part of the gas-liquid mixed flow sucked from the suction port 3802 provided at a part of the gas-liquid mixed outlet of the venturi tube 3801 without immersing the venturi pipe 3801 in the liquid tank is originally a gas suction port 3805. , And again passes through the narrowed portion of the Venturi tube 3801 to become finer microbubbles. Since this cycle is repeated endlessly, the microbubbles in the liquid tank rapidly become highly concentrated, and the effect of cleaning an object to be cleaned in the liquid tank is increased. In addition, the embodiment of FIG. 38 does not necessarily immerse the Venturi tube 3801 in the liquid tank, so that the impurities in the liquid tank are not sucked, and new liquid is always sucked. Therefore, the narrow portion of the Venturi tube 3801 may be clogged with impurities. Absent.
The venturi tube 3801 of FIG. 38 is also replaced with an aspirator having a structure similar to that of the venturi tube shown in FIG. 40, that is, an aspirator (not shown) that self-sucks a part of the gas-liquid mixed flow from the gas-liquid mixed outlet at the gas inlet. it can.
Further, the gas / liquid mixed flow supplied to the liquid inlet of the venturi tube or the aspirator may be a gas / liquid mixed flow discharged from the semi-sealed tank of the present invention, or a gas / liquid generated from a known microbubble generating device (not shown). A mixed stream may be supplied.

FIG. 39 shows a Venturi tube 3901 used in FIG. A gas suction port is indicated by 3905, and a gas-liquid mixed outlet is indicated by 3902.

FIG. 40 shows a Venturi tube 4001 used in FIG. A gas suction port 4005 and a suction port 4003 for sucking a part of the gas-liquid mixed flow at the venturi tube outlet 4002 are shown.

FIG. 41 shows a technique for generating fine bubbles of a French company, which has been described in detail above.

Similar effects can be obtained by using the aspirator shown in FIG. 32A instead of the Venturi tubes shown in the above embodiments.

Prof. Nobuhiko Miwa of Hiroshima Prefectural University of Life and Environmental Studies; http://www.water-institute.org/news/20060131.html (Chinese newspaper, February 9, 2006) At the “Japan Pharmaceutical Association” held in May, a group of Prof. Nobuhiko Miwa from the Prefectural University of Hiroshima Life and Environmental Sciences has been found to have anticancer effects and active oxygen suppression effects on new high-concentration dissolved hydrogen water The research results are announced. When normal water and water with high dissolved hydrogen were added to human tongue cancer cells and cultured, cancer cells continued to grow in normal water, but the growth was reduced to one third in water with high dissolved hydrogen. Suppressed. It is an interpretation that active oxygen, which is thought to be the cause of carcinogenesis, was erased by dissolved hydrogen. ”

Achievement of Prof. Naruo Ota of Nihon Medical University Graduate School; (May 8, 2007 / Yomiuri Shimbun) Hydrogen is effective in treating cerebral infarction, confirmed by the Nippon Medical University team in animal experiments; “Reactive oxygen causing arteriosclerosis, Prof. Naruo Ota, a professor at Nihon Medical University Graduate School, has confirmed in an animal experiment that the effect of removing hydrogen and reducing brain damage caused by cerebral infarction to less than half. It is expected to develop a therapeutic agent for cerebral infarction, etc. The research results will be published in the scientific journal Nature Medicine (electronic version) on the 8th. Although effective, it is said to be the “rust” of the body, and is considered to be a masterpiece of aging, especially in cerebral infarction, when a clogged blood flow resumes, a large amount of active oxygen is generated and damages the brain. The professors made an artificial stroke One rat was given 2% hydrogen gas, and the other was given no blood, and blood flow was resumed without giving anything, and as a result, the degree of brain damage in rats given hydrogen gas was given nothing. There were several types of active oxygen, and hydrogen was found to act only on the most oxidizing “hydroxyl radical”. Prof. Ota says, "Hydrogen does not act on good active oxygen. It is more promising and promising than existing treatments for cerebral infarction." ”
