Description

  The present invention relates to a nanobubble-containing water production apparatus and a nanobubble-containing water production method for producing nanobubble-containing water containing nanobubbles.

  Bubbles having a small diameter can be classified into microbubbles, micronanobubbles and nanobubbles according to their sizes. The bubbles are known to have various physiological actions, and at present, attention is being paid to techniques for producing such bubbles and their effects.

  For example, conventionally, a bathtub that uses fine bubbles to absorb useful substances into the body through the skin has been used (see, for example, Patent Document 1). The bathtub includes a container that contains a liquid containing a useful substance and a fine bubble generator that generates fine bubbles in the liquid in the bathtub. The fine bubble generator generates fine bubbles in the hot water in the bathtub. Let And the microscopic bubble is utilized and the percutaneous absorption of the useful substance in bath water is promoted.

  Conventionally, a waste liquid treatment apparatus using microbubbles (ozone microbubbles) made of ozone gas has been used (see, for example, Patent Document 2). In the waste liquid treatment apparatus, microbubbles made of ozone gas are produced by mixing ozone gas produced by an ozone generator and waste liquid using a pressure pump. Then, the microbubbles chemically react with the organic matter in the waste liquid, so that the organic matter in the waste liquid is oxidatively decomposed.

  Further, conventionally, a method for producing nanobubbles using a liquid as a raw material is known (see, for example, Patent Document 3). In the liquid, the production method includes 1) a step of decomposing and gasifying a part of the liquid, 2) a step of applying ultrasonic waves to the liquid, or 3) a step of decomposing and gasifying a part of the liquid A step of applying ultrasonic waves to the liquid. It is described that an electrolysis method or a photolysis method can be used as a step of decomposing and gasifying a part of the liquid.

Conventionally, methods for using nanobubbles and various devices using nanobubbles are known (see, for example, Patent Document 4). More specifically, in Patent Document 4 described above, nanobubbles have a surface active action and a bactericidal action by reducing buoyancy, increasing surface area, increasing surface activity, generating a local high-pressure field, or realizing electrostatic polarization. It is described to show. Furthermore, Patent Document 4 describes a technique for cleaning various objects and a technique for purifying polluted water using the surface-active action and bactericidal action of nanobubbles. Furthermore, Patent Document 4 describes a method for recovering fatigue of a living body using nanobubbles. In Patent Document 4, nanobubbles are produced by electrolyzing water and applying ultrasonic vibration to the water.

  However, in the conventional nanobubble generator and nanobubble generation method, the nozzle diameter for discharging nanobubbles is small. Therefore, if there is a floating substance in the liquid used to generate the nanobubbles, the floating substance adheres to the nozzle outlet as the nanobubbles are generated, and as a result, the nozzle outlet is blocked. Has a point. If the discharge port of the nozzle is blocked, a prescribed amount of nanobubbles cannot be generated, and thus there is a problem that various effects possessed by the nanobubbles cannot be sufficiently exhibited.

  The present invention has been made in view of the above-described conventional problems, and the object thereof is a nanobubble-containing water production apparatus and a nanobubble-containing water production in which the nozzle outlet is not blocked even if nanobubbles are ejected for a long time. It is to provide a method.

  As a result of intensive studies in view of the above problems, the present inventors have found the following 1) to 4) and have completed the present invention.

  1) Since the microbubble has a negative charge, it easily adheres to the suspended matter, and the suspended matter-microbubble complex in which the microbubble adheres to the suspended matter can be removed by floating the microbubble-containing water. What you can do.

  2) Gas bubbles and liquids can be mixed if nanobubbles are produced using microbubbles generated by a microbubble generator and floating in the microbubble-containing water without floating in the microbubble-containing water because of its small size. The lifetime of the circulation pump is increased and the production efficiency of nanobubbles is increased.

  3) The optimum amount of microbubbles to be supplied to the nanobubble generator can be controlled by controlling the electromagnetic flow meter.

  That is, when introducing many microbubbles into the nanobubble generator, if a large amount of liquid is caused to flow based on the measurement value of the electromagnetic flow meter, the flow velocity between the partition plates in the second tank described later becomes faster, As a result, the microbubbles are introduced into the nanobubble generator without rising, and it is possible to manufacture larger-sized nanobubbles among the nanobubbles. And, when introducing a small number of microbubbles into the nanobubble generator, if a small amount of liquid is flowed based on the measured value of the electromagnetic flow meter, the flow rate between the partition plates in the second tank, which will be described later, is slowed. , Large-sized microbubbles rise and disappear, and only small-sized microbubbles are introduced into the nanobubble generator, making it possible to produce a large amount of smaller-sized nanobubbles among nanobubbles. To become a.

  4) The size and the amount of nanobubbles produced by the nanobubble generator can be indirectly controlled by adjusting the discharge amount of the transfer pump (transfer pump 9 described later) with an electromagnetic flow meter. That is, the discharge amount of the transfer pump and the size and amount of nanobubbles are in a proportional relationship.

  In order to solve the above problems, the nanobubble-containing water production apparatus of the present invention is a microbubble-containing water preparation means for producing microbubble-containing water by bringing floating substance-containing water into contact with microbubbles, Removal means for removing suspended matter-microbubble complex adhered to suspended matter in suspended matter-containing water, and nanobubbles by shearing the microbubble-containing water after the suspended matter-microbubble complex is removed by the removal means And nanobubble-containing water preparation means for preparing the contained water.

  According to the above configuration, the microbubble-containing water is prepared by bringing the floating-substance-containing water and the microbubbles into contact with each other by the microbubble-containing water preparation means. At this time, since the microbubble has a negative charge, at least a part of the microbubble adheres to the suspended substance in the suspended substance-containing water to form a suspended substance-microbubble complex. Since buoyancy acts on the floating substance-microbubble complex, the floating substance-microbubble complex floats in the water containing microbubbles and is separated by the removing means. And if the microbubble containing water after a floating substance-microbubble composite_body | complex is removed is sheared, nanobubble containing water can be produced efficiently.

  In the nanobubble-containing water production apparatus of the present invention, the microbubble-containing water after the floating substance-microbubble complex is removed by the removing means is introduced, and the bubbles floating on the water surface of the microbubble-containing water are It is preferable to have a bubble selection means for removing from the microbubble-containing water.

  According to the said structure, microbubble containing water is introduce | transduced in a bubble selection means, and microbubble containing water is hold | maintained in a bubble selection means only after desired time after that. Therefore, the large bubbles contained in the microbubble-containing water are released from the surface of the microbubble-containing water while being held. As a result, small bubbles are selectively contained in the microbubble-containing water. And if nanobubble containing water is produced using the microbubble containing water containing the said small bubble, the size of the nanobubble contained in the said nanobubble containing water can be made small.

  In the nanobubble-containing water production apparatus of the present invention, it is preferable that the removing means sucks at least the surface layer of the microbubble-containing water in the microbubble-containing water preparation means.

  According to the above configuration, the suspended matter-microbubble complex floats near the surface layer of the microbubble-containing water, so that the suspended matter-microbubble complex can be efficiently removed.

  In the nanobubble-containing water production apparatus of the present invention, the microbubbles are preferably produced by an underwater pump type microbubble generator or an ultra-high speed swirl type microbubble generator.

  According to the said structure, a microbubble can be easily generated with a microbubble generator. In addition, since the submersible pump type microbubble generator can produce many microbubbles, if it is used when the suspended matter concentration in suspended matter-containing water is high, it will separate many suspended matter-microbubble complexes. be able to. Also, the submersible pump type microbubble generator can be easily installed because it can generate microbubbles only by putting the main body into the water tank, except for a small blower. On the other hand, the ultra-high speed swirl type micro bubble generator has a smaller size of the generated micro bubbles than the submersible pump type micro bubble generator. Therefore, if it is used when the suspended matter concentration in the suspended matter-containing water is low, the suspended matter-microbubble complex can be more reliably separated.

  In the nanobubble-containing water production apparatus of the present invention, the microbubbles are preferably formed of air, ozone gas, carbon dioxide gas, oxygen gas, or nitrogen gas.

  According to the said structure, the nanobubble containing water containing the nanobubble which uses air, ozone gas, carbon dioxide gas, oxygen gas, or nitrogen gas as a component can be produced. For example, since air exists in large quantities, the material cost of nanobubbles can be kept low, and a configuration for generating microbubbles can be manufactured at low cost. Moreover, for example, ozone gas has a strong oxidizing power, so that nanobubble-containing water having a strong oxidizing power can be produced. Moreover, since nanobubbles containing ozone gas as a component can exist in the nanobubble-containing water for a long time, a desired substance can be completely oxidized. In addition, for example, nanobubble-containing water containing nanobubbles containing carbon dioxide as a component has a cleaning action, a blood flow rate and an insulin-like growth factor increasing action, and thus the nanobubble-containing water can be used as bath water. In addition, for example, nanobubble-containing water containing nanobubbles containing oxygen gas as a component can increase dissolved oxygen in the water, so it should be used for wastewater treatment, aquaculture, live fish farming, and live fish transport using oxygen gas. Can do. In addition, for example, nanobubble-containing water containing nanobubbles containing nitrogen gas as a component has an antioxidant action, and thus can prevent oxidation of objects and products that are vulnerable to oxidation.

The first shearing is performed on the contained water, and the second gas shearing unit is configured to perform the second shearing on the microbubble-containing water after the first shearing, and the third The gas shearing part is preferably one that performs the third shearing on the microbubble-containing water after the second shearing.

  According to the said structure, since microbubble containing water can be sheared 3 times, refinement | miniaturization of a bubble progresses further and, as a result, the quantity of the nanobubble in nanobubble containing water can be increased.

  In the nanobubble-containing water producing apparatus of the present invention, the cross section of the inside of the first gas shearing part is an ellipse or a perfect circle, and the inside of the first gas shearing part is formed by mirror finishing. preferable.

  According to the above configuration, the microbubble-containing water can be swirled at a high speed and the microbubble-containing water can be efficiently sheared, so that many nanobubbles can be generated.

  In the nanobubble-containing water production apparatus of the present invention, the first gas shearing unit includes an inlet for taking microbubble-containing water before shearing into the first gas shearing unit, and microbubble-containing water after shearing. It is preferable that the diameter of the discharge port is 50 to 80% of the diameter of the introduction port.

  According to the said structure, a microbubble can be stably generated in the said 1st gas shearing part. And if the said micro bubble is used, a nano bubble can be stably generated in the said 2nd gas shear part and a 3rd gas shear part. In general, in order to stably generate microbubbles, it is necessary to increase the discharge pressure of water containing microbubbles. According to the above configuration, the discharge pressure of the microbubble-containing water is such that the diameter of the discharge port is smaller than the diameter of the introduction port, specifically, the diameter of the discharge port is 50 to 80% of the diameter of the introduction port. As a result, microbubbles can be generated stably.

  In the nanobubble-containing water production apparatus of the present invention, it is preferable that two or more grooves are provided inside the first gas shearing portion.

  According to the said structure, the turning motion of the microbubble containing water in the inside of the 1st gas shearing part can be controlled by the said groove | channel. That is, according to the said structure, generation | occurrence | production of the turning turbulent flow inside a 1st gas shear part is controllable. As a result, a large amount of microbubbles can be stably generated by the first gas shearing portion. And if the said micro bubble is used, a nano bubble can be stably generated in the said 2nd gas shear part and a 3rd gas shear part.

  In the nanobubble-containing water production apparatus of the present invention, the first gas shearing section discharges 1.5 liters to 120 liters of microbubble-containing water per minute toward the second gas shearing section. The microbubble-containing water discharged per minute preferably contains 0.3 to 1.5 liters of microbubbles.

  According to the said structure, a lot of nanobubble containing water can be manufactured stably.

  In the nanobubble-containing water production apparatus of the present invention, the material of the first gas shearing part is preferably stainless steel, plastic, or resin.

  According to the said structure, the material of a said 1st gas shearing part can be selected according to the intended purpose of nanobubble containing water. For example, in the pharmaceutical industry, it is necessary to prevent impurities such as metals from being mixed into the medicine. In this case, if it is the said structure, since possibility that the material of a 1st gas shear part will mix is low, manufactured nanobubble containing water can be used for manufacture of a pharmaceutical, ie, pharmaceutical.

  In the nanobubble-containing water production apparatus of the present invention, it is preferable that the material thickness of the first gas shearing part is 4 mm to 5 mm.

  According to the said structure, since the material of a 1st gas shear part is formed thickly, a 1st gas shear part does not vibrate. That is, even if the microbubble-containing water swirls inside the first gas shearing portion, the first gas shearing portion does not vibrate thereby. Accordingly, the fluid kinetic energy of the microbubble-containing water swirling inside the first gas shearing portion is not propagated and lost to the outside (for example, external gas) as vibration, so the microbubble-containing water is While being able to rotate, the shear energy of microbubble containing water can be maintained. As a result, microbubbles can be efficiently generated at the first gas shearing portion.

  In the nanobubble-containing water producing apparatus of the present invention, the second gas shearing section and the third gas shearing section have an elliptical shape or a true circular cross section, and the inner surfaces of the second gas shearing section and the third gas shearing section. It is preferable that a hole is formed in the hole and the hole diameter of the hole is 4 mm to 9 mm.

  According to the above configuration, the swirling motion of the bubble-containing water inside the second gas shearing portion and the third gas shearing portion can be controlled. That is, according to the said structure, generation | occurrence | production of the turning turbulent flow inside the said 2nd gas shearing part and a 3rd gas shearing part is controllable. As a result, nanobubbles can be stably generated by the second gas shearing portion and the third gas shearing portion.

  In the nanobubble-containing water production apparatus of the present invention, the amount of suspended matter contained in the suspended matter-containing water is preferably 1 ppm or less.

  According to the said structure, since the quantity of the floating substance contained in floating substance containing water is 1 ppm or less, a floating substance-microbubble composite_body | complex can be formed efficiently. That is, microbubbles adhere to most of the suspended matter contained in the suspended matter-containing water to form a suspended matter-microbubble complex. As a result, most of the suspended matter contained in the suspended matter-containing water can be separated. And since nanobubble containing water is produced using the microbubble containing water with little content of a suspended | floating matter, the water containing nanobubble can be manufactured efficiently.

  In the nanobubble-containing water production apparatus of the present invention, the submersible pump-type microbubble generator or the superbubble generator is prepared so that the microbubble-containing water is supplied to the nanobubble-containing water preparation means 60 seconds after the start of preparation of the nanobubble-containing water. It is preferable to provide a sequencer for adjusting microbubble production in the high-speed swirl type microbubble.

  According to the above configuration, nanobubbles can be generated stably by preventing damage to the impeller of the gas-liquid mixing circulation pump.

A removal step of removing suspended matter-microbubble complex attached to suspended matter in suspended matter-containing water, and nanobubbles by shearing the microbubble-containing water after removing the suspended matter-microbubble complex in the removal step And a nanobubble-containing water production step for producing the contained water.

  According to the above configuration, the microbubble-containing water is produced by bringing the floating substance-containing water into contact with the microbubbles in the microbubble-containing water production step. At this time, since the microbubble has a negative charge, at least a part of the microbubble adheres to the suspended substance in the suspended substance-containing water to form a suspended substance-microbubble complex. Since buoyancy acts on the floating substance-microbubble complex, the floating substance-microbubble complex floats in the water containing microbubbles and is separated by the removing step. And if the microbubble containing water after a floating substance-microbubble composite_body | complex is removed is sheared, nanobubble containing water can be produced efficiently.

  In the nanobubble-containing water production method of the present invention, the bubble selection step of removing bubbles floating on the water surface of the microbubble-containing water after the suspended matter-microbubble complex has been removed by the removing step from the microbubble-containing water. It is preferable to have.

  According to the said structure, in the bubble selection process, the big bubble contained in microbubble containing water is discharge | released from the surface of microbubble containing water. As a result, small bubbles are selectively contained in the microbubble-containing water. And since nanobubble containing water is produced using the microbubble containing water containing the said small bubble, the size of the nanobubble contained in the said nanobubble containing water can be made small.

  In the nanobubble-containing water production method of the present invention, the nanobubble-containing water preparation step preferably includes a plurality of steps of shearing the microbubble-containing water.

  According to the said structure, since microbubble containing water can be sheared in multiple times, refinement | miniaturization of a bubble progresses further and, as a result, the quantity of the nanobubble in nanobubble containing water can be increased.

[Embodiment 1]
An embodiment of the present invention will be described with reference to FIG.

  First, “microbubbles” and “nanobubbles” used in this specification will be described. “Microbubbles” are intended to be fine bubbles having a diameter of 50 microns (μm) or less. “Nanobubbles” are bubbles smaller than microbubbles, and are intended to be fine bubbles having a diameter of 1 micron or less (100 nm to 200 nm). In general, microbubbles shrink in water and eventually disappear (completely dissolve). On the other hand, nanobubbles can exist stably in water for a long time compared to microbubbles.

  The nanobubble-containing water production apparatus 1 according to the present embodiment includes a storage tank 10, a nanobubble generation tank 2, and a nanobubble generator 24 (nanobubble-containing water preparation means).

  The storage tank 10 is introduced with floating substance-containing water. In this specification, “floating substance-containing water” means a liquid containing floating substance. In addition, the nanobubble containing water manufacturing apparatus and nanobubble containing water manufacturing method of this invention can introduce | transduce the liquid which does not contain a floating substance, and can also manufacture nanobubble containing water.

  The floating substance and liquid are not particularly limited. Floating substance-containing water includes, for example, floating substance-containing wastewater, floating substance-containing water, floating substance-containing groundwater, floating substance-containing bath water, floating substance-containing health drink ingredients, raw material liquids containing floating substances as pharmaceuticals, floating substances Examples include, but are not limited to, substance-containing solvent raw materials, floating substance-containing crude oil, floating substance-containing gasoline, floating substance-containing bioethanol, and floating substance-containing fermentation broth.

  A transfer pump 9 is installed in the storage tank 10 into which floating substance-containing water is introduced. When the water level in the storage tank 10 exceeds a certain level, the transfer pump 9 is operated based on signals from the level controller 43 and the sequencer 6. A signal transmitted from the sequencer 6 is transmitted to each component via the signal line 5. In addition, signals transmitted from the respective components are also transmitted to the sequencer 6 through the signal line 5. The transfer pump 9 transfers floating substance-containing water via the pipe 27. For example, when the electric valve 8 is opened, at least a part of the floating substance-containing water returns to the reservoir 10 and the inside of the reservoir 10 is agitated. On the other hand, when the electric valve 7 is opened, at least a part of the floating substance-containing water is provided in the first tank 21 (microbubble-containing water preparation means) of the nanobubble generation tank 2 via the pipe 36. It is transferred to the inflow pipe 37. At this time, the flow rate of the floating substance-containing water transferred through the pipe 36 is measured by the electromagnetic flow meter 25. Therefore, if the electric valve 7 and the electric valve 8 are opened and closed by the sequencer 6 based on the measured value of the electromagnetic flow meter 25, the flow rate of the floating substance-containing water transferred through the pipe 36 can be controlled.

  The inflow pipe 37 in the tank is used for efficiently bringing microbubbles generated from the submersible pump type microbubble generator 19 into contact with floating substance-containing water. The shape of the inflow tank 37 in the tank is not particularly limited, but it is preferable that the inlet portion and the outlet portion are wide. According to the said structure, it becomes possible to introduce the floating substance containing water in the inflow pipe 37 in a tank reliably.

  The microbubbles generated from the submersible pump type microbubble generator 19 form a water flow 20 in the first tank 21. Since the microbubble has a negative charge, the microbubble adheres to the suspended substance in the suspended substance-containing water to form a suspended substance-microbubble complex. The floating substance-microbubble composite gradually rises in the first tank 21 to become a floating substance scum 39 to which fine bubbles are attached. When the floating material scum 39 increases by a certain amount or more, it is discharged out of the first tank 21 through the discharge pipe 38 (removing means) and the pipe 26. As a result, the amount of suspended matter in the suspended matter-containing water can be reduced, and microbubble-containing water can be produced. Instead of the submersible pump type microbubble generator 19, it is also possible to use an ultra high speed swirl type microbubble generator. If these structures are used, microbubbles can be generated efficiently.

  The discharge pipe 38 is not particularly limited as long as it can remove the floating substance scum 39 from the water containing microbubbles. For example, it may be an opening provided on the side surface of the first tank 21 and in the vicinity of the water surface of the microbubble-containing water, or a suction pipe for sucking the surface layer of the microbubble-containing water. Further, these configurations may include a suction pump for positively sucking the levitated material scum 39. Further, the discharge pipe 38 may be configured using a scum skimmer that can efficiently remove the floating material scum 39.

  As described above, microbubbles are supplied into the first tank 21 by the submersible pump type microbubble generator 19. A gas taken in from the pipe 35 is supplied to the submersible pump type microbubble generator 19 by the blower 42, and microbubbles containing the gas as a component are formed. In addition, when supplying gas with the blower 24, the electric valve 34 is opened and gas is taken in from the piping 35. The gas is not particularly limited, and for example, air, ozone gas, carbon dioxide gas, oxygen gas, or nitrogen gas can be used. In this case, it is preferable to connect a gas cylinder capable of storing the gas to one end of the pipe 35. Thereby, microbubbles containing a desired gas as a component can be generated. When air is used as the gas, one end of the pipe 35 can be opened indoors.

  In the nanobubble-containing water production apparatus of the present embodiment, the sequencer 6 causes the transfer pump 9, the electric valve 7, the electric valve 8, the electromagnetic flow meter 25, the blower 42, the electric valve 34, the submersible pump type microbubble generator 19, and The gas-liquid mixing circulation pump 11 is controlled. That is, since the sequencer 6 can freely set the operation of each of the above configurations, the desired nanobubble-containing water can be produced.

  The microbubble-containing water from which suspended substances are removed in the first tank 21 flows into the second tank 22 (bubble selecting means) in which the flow path of the microbubble-containing water is formed by the upper partition plate 16 and the lower partition plate 18. To do. The number of each of the upper partition plate 16 and the lower partition plate 18 in the second tank 22 is not particularly limited. For example, two upper partition plates 16 and two lower partition plates 18 can be used, but are not limited thereto.

  Further, the electric valve 34 is opened and closed so that the amount of gas (for example, the amount of air) supplied to the submersible pump type microbubble generator 19 installed in the first tank 21 is 0.7 liter / min. It is preferable to set the degree of. According to the above configuration, the nanobubble-containing water produced by the nanobubble-containing water production apparatus of the present embodiment contains a large amount of nanobubbles. Further, if the amount of microbubbles contained in the water containing microbubbles in the second tank 22 is increased (for example, the amount of air greater than 0.7 liter / min is supplied by adjusting the degree of opening and closing of the electric valve 34). If so, the nanobubble-containing water produced by the nanobubble-containing water production apparatus of the present embodiment contains both nanobubbles and microbubbles.

  In this case, a calibration curve indicating the relationship between the value of the electromagnetic flow meter 25 and the amount of microbubbles contained in the microbubble-containing water of the second tank 22 may be created in advance. And if the sequencer 6 is operated so that the value of the electromagnetic flow meter 25 shows a desired value, the amount of microbubbles contained in the water containing microbubbles in the second tank 22 can be adjusted. In order to create the calibration curve, first, the microbubble-containing water in the second tank 22 is sampled and the initial volume is measured using a graduated cylinder or the like, and the value of the electromagnetic flow meter 25 at this time is measured. Record. Next, the sample is allowed to stand for 1 hour or longer, and the volume after the microbubbles are removed is measured. If the volume difference is calculated, the amount of microbubbles when the electromagnetic flow meter 25 shows a specific value can be measured, and as a result, a calibration curve can be created.

  The microbubble-containing water in which the amount of microbubbles is adjusted in the second tank 22 becomes a water flow 15 and flows into the third tank 23. A nanobubble generator 24 is provided over the third tank 23 and the outside of the third tank 23. Then, the nanobubble generator 24 produces nanobubble-containing water using the microbubble-containing water. The nanobubble generator 24 includes a gas-liquid mixing / circulation pump 11 having a microbubble generator 12 (first gas shearing section), a second gas shearing section 14, a third gas shearing section 17, and a pipe connecting them. . The nanobubble generator 24 is connected to the sequencer 6. Therefore, the transfer pump 9, the electric valve 7, the electric valve 8, the electromagnetic flow meter 25, the blower 42, the electric valve 34, the submersible pump type microbubble generator 19, and the gas-liquid mixing / circulation pump 11 are controlled by the program in the sequencer 6. Can be controlled.

  The nanobubble generator 24 will be described below.

  As described above, the nanobubble generator 24 includes the gas-liquid mixing circulation pump 11 having the microbubble generator 12, the second gas shearing unit 14, and the third gas shearing unit 17.

  In the conventional nanobubble generator, there is a pipe for introducing gas into the microbubble generator 12, but in the present invention, microbubble-containing water is taken into the microbubble generator 12 from the pipe 3. Then, in the microbubble generating unit 12, finer microbubbles are produced using the microbubbles contained in the microbubble-containing water. The microbubble-containing water containing the fine microbubbles then becomes nanobubble-containing water via the second gas shearing part 14 and further contains nanobubbles containing nanobubbles of a desired size via the third gas shearing part 17. It becomes water. And the said nano bubble containing water forms the water flow 4, and is discharged. The discharged nanobubble-containing water is transferred via a pipe 28 to a device 29 that can perform the next process. The device 29 is not particularly limited, and a known configuration can be used as appropriate according to the purpose.

  The nanobubble generator 24 produces nanobubble-containing water through the first step and the second step. The first step and the second step will be described below.

[First step]
In the first step, in the microbubble generation unit 12, the pressure of the microbubble-containing water is controlled hydrodynamically using the gas-liquid mixing circulation pump 11, and gas is sucked from the negative pressure unit. The “negative pressure part” means a region in the gas / liquid mixture where the pressure is smaller than that of the surroundings. Then, microbubble-containing water is moved at high speed to form a negative pressure portion, and microbubbles are generated by shearing the microbubbles. In other words, the liquid and gas forming the microbubble-containing water are effectively self-mixed and dissolved, and are pumped. Thereby, microbubble-containing water containing finer microbubbles is formed.

Although it does not specifically limit as the gas-liquid mixing circulation pump 11, It is preferable that it is a pump with a high head of 40 m or more (pressure of 4 kg / cm < ² >). The gas-liquid mixing circulation pump 11 is preferably a two-pole pump with stable torque. According to the said structure, it is possible to apply a desired pressure with respect to the microbubble containing water in the microbubble generating part 12, As a result, the microbubble contained in microbubble containing water is sheared more finely Can do.

  Moreover, it is preferable that the pressure of the gas-liquid mixing circulation pump 11 is controlled. Therefore, in the nanobubble-containing water production apparatus of the present embodiment, the gas-liquid mixing circulation pump 11 is controlled by a program in the sequencer 6 or the like. For example, the pressure of the gas-liquid mixing circulation pump 11 can be controlled by controlling the rotation speed of the gas-liquid mixing circulation pump 11 with an inverter. If the pressure of the gas-liquid mixing circulation pump 11 can be controlled, a desired pressure can be applied to the microbubble-containing water in the microbubble generator 12, and as a result, the microbubble-containing water is included. Microbubbles can be sheared more finely.

  The material of the microbubble generator 12 is not particularly limited, but is preferably stainless steel, plastic, or resin. Although the thickness of the microbubble generation part 12 is not specifically limited, If it is the nanobubble containing water manufacturing apparatus of this Embodiment, it is possible to make the said thickness into 4 mm-5 mm. In addition, the conventional microbubble generation | occurrence | production part is 6 mm-12 mm in thickness. This makes it possible to produce the microbubble generator 12 at a low cost. In general, if the microbubble generating portion 12 is thin, the microbubble generating portion 12 vibrates due to the movement of the microbubble-containing water in the microbubble generating portion 12. As a result, the kinetic energy propagates to the outside as vibration and escapes, so that the high-speed flow motion of the microbubble-containing water is reduced and the shear energy is reduced. However, in the nanobubble-containing water production apparatus of the present embodiment, since the microbubbles are produced in advance by the submersible pump type microbubble generator 19, the kinetic energy of the microbubble-containing water in the microbubble generator 12 is small. Good. As a result, it is possible to reduce the thickness of the microbubble generator 12 as compared with the conventional case.

  Next, the mechanism by which the gas-liquid mixing circulation pump 11 having the microbubble generator 12 generates fine microbubbles will be described.

  First, the microbubble generator 12 generates a mixed phase swirl of liquid and gas, which are constituents of microbubble-containing water. Specifically, a wing called an impeller is rotated at an ultra high speed to generate a mixed phase swirl of liquid and gas. At this time, a gas cavity that swirls at high speed is formed at the center of the microbubble generator 12. Next, the gas cavity is narrowed in a tornado shape by pressure to generate a rotating shear flow that swirls at a higher speed. A gas (a microbubble contained in microbubble-containing water) is automatically supplied to the hollow portion using a negative pressure. Further, the multiphase flow is rotated while cutting / pulverizing the microbubbles. The cutting and pulverization is caused by a difference in rotational speed between the internal and external gas-liquid two-phase fluids near the outlet of the microbubble generator 12. The difference in rotational speed at that time is preferably 500 to 600 revolutions / second.

  That is, in the microbubble generating unit 12, gas is sucked from the negative pressure unit by controlling the pressure of the microbubble-containing water hydrodynamically, and the microbubble-containing water is moved at high speed by the gas-liquid mixing circulation pump 11. As a result, finer microbubbles can be generated. In other words, microbubble-containing water containing finer microbubbles can be produced by pumping the liquid and gas by the gas-liquid mixing circulation pump 11 while effectively self-mixing and dissolving.

  The internal shape of the microbubble generator 12 is not particularly limited, but is preferably elliptical, and most preferably a perfect circle. Moreover, it is preferable that the inside of the microbubble generation part 12 is further formed by mirror finishing. According to the said structure, since the internal friction of the microbubble generation | occurrence | production part 12 is small, while rotating microbubble containing water at high speed, microbubble containing water can be sheared efficiently. As a result, many fine microbubbles can be generated, and finally many nanobubbles can be generated.

  Moreover, it is preferable to provide a groove having a depth of approximately 0.3 mm to 0.6 mm and a width of approximately 0.8 mm within the microbubble generating portion 12. According to the above configuration, since the swirling turbulent flow of the microbubble-containing water in the microbubble generating unit 12 can be controlled, many fine microbubbles can be generated and finally many nanobubbles can be generated. Can be generated.

  In addition, the microbubble generator 12 has an inlet for taking microbubble-containing water into the microbubble generator 12 and an outlet for discharging the microbubble-containing water after shearing. At this time, the diameter of the discharge port is preferably shorter than the diameter of the introduction port, and the diameter of the discharge port is most preferably 50 to 80% of the diameter of the introduction port. According to the said structure, since the discharge pressure of microbubble containing water can be raised, a microbubble can be generated stably.

[Second step]
In the second step, nanobubbles are generated from the microbubbles by further shearing the microbubble-containing water after passing through the microbubble generating unit 12 by the second gas shearing unit 14 and the third shearing unit 17.

  When the microbubble-containing water is pumped from the microbubble generating unit 12 to the third gas shearing unit 17 via the second gas shearing unit 14 by the gas-liquid mixing circulation pump 11, the microbubble-containing water is pumped. It is preferable that the diameter of the pipe decreases gradually or stepwise in the direction. According to the above configuration, the microbubble-containing water can be thinned like a tornado while performing fluid motion at a higher speed. In other words, it is possible to generate a rotating shear flow that swirls at a higher speed. As a result, nanobubbles can be generated from the microbubbles and an ultra-high temperature extreme reaction field can be formed. When the above extreme reaction field is formed, a high temperature and high pressure state is locally generated, unstable free radicals are formed, and heat is generated at the same time. A free radical is an atom or molecule having an unpaired electron, and attempts to stabilize by taking electrons from other atoms or molecules. Therefore, free radicals exhibit strong oxidizing power. According to the said structure, the organic substance etc. in a liquid can be oxidatively decomposed with a free radical.

  If two configurations of the second gas shearing portion 14 and the third gas shearing portion 17 are used as in the nanobubble-containing water production apparatus of the present embodiment, a large amount of nanobubbles are formed compared to the case of using one configuration. can do.

  Moreover, it is preferable that the 2nd gas shearing part 14 and the 2nd gas shearing part 17 are formed with stainless steel, a plastics, or resin. According to the said structure, the material of the said 2nd gas shear part 14 and the 2nd gas shear part 17 can be selected according to the intended purpose of nanobubble containing water. For example, in the pharmaceutical industry, it is necessary to avoid contamination of drugs with impurities. In this case, if it is the said structure, since the possibility that the material of the 2nd gas shearing part 14 and the 2nd gas shearing part 17 will mix is low, manufactured nanobubble containing water is used for manufacture of a pharmaceutical, ie, pharmaceutical. Can do.

  Moreover, it is preferable that the internal shape of the 2nd gas shear part 14 and the 2nd gas shear part 17 is an ellipse, and it is most preferable that it is a perfect circle. According to the above configuration, since the internal resistance of the second gas shearing portion 14 and the second gas shearing portion 17 is small, the microbubble-containing water can be swirled at a high speed and the microbubble-containing water can be efficiently sheared. As a result, many nanobubbles can be generated.

  Further, it is preferable that a hole is opened in the main body central portion of the second gas shearing portion 14 and the third gas shearing portion 17. The diameter of the opening of the hole is not particularly limited, but is preferably 4 mm to 9 mm. According to the above configuration, the swirling motion of the bubble-containing water inside the second gas shearing portion and the third gas shearing portion can be controlled. That is, according to the said structure, generation | occurrence | production of the turning turbulent flow inside the said 2nd gas shearing part and a 3rd gas shearing part is controllable. As a result, nanobubbles can be stably generated by the second gas shearing portion and the third gas shearing portion.

  The gas-liquid mixing circulation pump 11, the microbubble generation unit 12, the gas shearing unit 14, and the gas shearing unit 17 constituting the nanobubble generator 24 are commercially available (for example, manufactured by Kyowa Kikai Co., Ltd.). Bavidas HYK type) can be used.

In this case, crude oil preheated by a heating furnace is introduced into the atmospheric distillation equipment. The company produces various petroleum products such as gasoline, kerosene, light oil, and heavy oil. However, this method has a problem that if there are a lot of suspended solids in the crude oil, the suspended solids adhere to the heat exchanger of the heating furnace and the heat exchange efficiency is lowered.

  On the other hand, the nanobubble-containing water production apparatus according to the present embodiment can remove suspended solids in crude oil and can contain nanobubbles in crude oil.
