Description

High concentration ozone water production device.

The present invention is to increase the efficiency of the high-concentration ozone-water production apparatus, in which an electrode is disposed in the water and a predetermined pulse voltage is applied to the counter electrode to cause an effective high voltage discharge and electrolysis in the water, thereby producing a high concentration of ozone in the water. It is about.

There are two ways to contain ozone in ordinary water. The first method is to generate ozone from corona discharge in air (or oxygen), to bring the ozone-containing air back into water and to allow ozone to dissolve in water. As it should be installed, there is a problem that the increase in price, as well as the efficiency reduction, blockage, noise, and ozone outflow from the exhaust air caused by these causes pollution to the environment.

As a second conventional method, a counter electrode is installed in water and a predetermined pulse voltage is applied to the counter electrode to generate ozone bubbles directly in the water, which is dissolved in the water. Nos. 36389, 40406, 54405.

This method of ozone generation in water generates molecular ozone directly in water, so it does not require a blower or bubble generator, and it is very effective, economical and sterilized with little residual ozone emission into the air causing secondary pollution. Disinfection, deodorization and discoloration, using strong oxidation, water and sewage treatment, food storage and sterilization, agricultural and fish sterilization, industrial wastewater treatment, odor and organic pollution gas treatment, pesticide substitutes, and pharmaceutical and food manufacturing processes. It is a technology that can be applied to various fields, such as processing, and more recently, also applied as a medical device such as dental.

As described above, the first method has a technical and economic problem, and the second method has a problem in that the amount of ozone generated (ie, ozone concentration) is not generated.

Figure 1 shows a conventional ozone water generator (A) having a relatively low output ozone concentration. The net electrode 1, 3 is spaced apart at an appropriate distance inside the water supply pipe 6, the ozone water discharge pipe 8, and the insulating case 9. In parallel to each other so that the supply water supplied through the water supply pipe 6 passes between the net electrodes 1 and 3, and is electrolyzed by a pulse waveform (Vps) applied to the conventional ozone water generator as shown in FIG. Ozone is generated and dissolved in water, and ozone water is discharged through the discharge pipe (8).

In the conventional ozone water generator (a), since the positive pulse voltage (Vp ₊ ) and the negative pulse voltage (Vp ₋ ) are alternately applied to the net electrodes (1) 3 as shown in FIG. Ozone is generated and dissolved alternately in the net electrodes (1) and (3) to come out of the water, and the separation distance between the net electrodes (1) and (3) is also set very short to operate at the lowest applied pulse voltage (0.01 to 3). 2 mm).

Therefore, the high pulse voltage is not applied and the ozone water generating ability is relatively weak, and even though a large amount of ozone is generated by reducing the water supply and increasing the applied pulse voltage, a large amount of current flows in a narrow space between the net electrodes (1) and (3). As much heat is generated in proportion to the square of, the ozone pyrolysis is decomposed into oxygen as shown in Eq. (1).

2O ₃ ----- → 3O ₂ ----- (1)

In addition, although pure platinum (Pt) is used as the electrode material, it has a disadvantage in that its lifetime is not long because a high fill voltage is applied.

The present invention improves the composition and structure of the electrode of the conventional underwater ozone generator (a), the shape and cycle and size of the applied power source, and the electrode material to improve the efficiency to produce water containing high concentration of ozone. The purpose.

In order to achieve the above object, the ozone generating electrode (positive electrode) is a platinum alloy (Pt + Pd) electrode containing palladium (Pd) which hardly precipitates in water, or a metal having a similar coefficient of thermal expansion to a ferroelectric (eg, dumet, Al, etc.). A strong fluid layer is formed on the membrane to greatly extend the life of the ozone generating electrode, the outer electrode is formed into a flat plate shape, and the inner electrode has a three-segment having openings (holes) through which water flows. Consists of a mold or a net electrode to reduce the speed of water flow between the internal electrodes and the separation distance between the electrodes to improve efficiency with low power consumption, and the applied voltage is controlled by applying a square wave pulse or similar waveform high voltage at an appropriate period to control water. High voltage electric discharge and electrolysis, as well as alternating applied pulse voltage, greatly reduces the rate of solid impurity scale on the electrode surface, Strong acidic water and steel containing high concentrations of strong oxidizing dissolved water by adding high concentration of ozone water, as well as the addition of Cl-containing additives (e.g. NaCl, KCl, etc.) needed to form HClO, one of the strong oxidants. Alkaline water and neutral water are also obtained so that the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

① Composition and form of electrode

To compensate for the problem of low concentration of output ozone water of the conventional ozone water generator (A), the positive electrode water (ozone water) on the side of the positive electrode water region (B) where ozone is manufactured and the negative electrode water area (A) on which ozone is not manufactured Separation and separation of the separator 12 into the positive electrode discharge pipe 18 and the negative electrode discharge pipe 16 resulted in a relatively high ozone concentration in the ozone water discharge pipe 18 as shown in equations (2) and (3).

Normal ozone water concentration = amount of ozone generation / water supply ----- (2)

Ozone water concentration of the present invention = amount of ozone generated / (water supply-cathode amount) ----- (3)

In this case, the separator 12 may have good electrical conductivity and may not mix water in the two regions (A) and (B).

The square wave pulse voltage Vp of FIG. 4 or the half wave pulse voltage Vpac of FIG. 5 may be applied to the applied power source of the ozone water producing apparatus (b) applied to the embodiment of the present invention.

In this case, however, impurities in the water supply adhere to the electrodes 11 and 13, and the current is rapidly attenuated within several tens of hours, thereby causing the ozone to be stopped. In order to solve this problem, it is necessary to reverse the polarity of the electrodes (11, 13).

That is, a positive voltage (positive) voltage is applied to the positive net electrode 13, and a positive voltage (positive) voltage is applied to the negative net electrode 11, but an applied power source between the two electrodes 11 and 13 is applied. Means for alternating polarity at appropriate time intervals (a few minutes to several tens of minutes) are required. At this time, the ozone water outlet is also changed, so a means for this (eg, an automatic converter using an electronic valve, etc.) is required.

Apparatus for producing ozone water applied to an embodiment of the present invention (b) is a bar-shaped positive net electrode 13 and a negative net electrode 11 as shown in Fig. 3 are installed on both sides of the separation membrane 12 at opposite intervals, respectively. As the planar area of the two electrodes 11 and 13 is as wide as possible and the separation distance d is narrow, the electrical resistance between the two electrodes 11 and 13 is reduced to effectively operate at the lowest voltage possible. The consumption of electrodes is also reduced.

However, in this case, since the two electrodes (d) are installed narrowly, water flow is formed between the two electrodes (11) and (13) as vortices, thus vertically around the two electrodes (11) (13). In addition to the problem of greatly reducing the electrolytic efficiency by turbulizing the current to be moved, the ions separated from each other between the two electrodes (d) are subjected to the space charge limiting action to reduce the voltage between the electrodes by acting as space charge. This further reduces the electrolysis.

As described above, the problem (turbulence generation) is achieved by using the two electrodes 11 and 13 as shown in FIG. 4 while increasing the relative flow width D while reducing the electrode spacing d between the two electrodes 11 and 13. The ozone water produced in the present invention can be solved by greatly reducing the water flow rate and turbulence between the electrodes by allowing the ozone water to come out to the wider outside (D). In this case, the distance (d) between the two electrodes (11) and (13) As it can be narrowed further, it can operate at a relatively high electric field even at a low applied voltage, which can cause very effective underwater discharge generation and electrolysis, as well as greatly improving power efficiency.

At this time, the electrode spacing d may be close to both sides of the separator 12 (d = 0) or largely separated from the separator 12 (d = D), and this value electrode spacing d may be required ozone water. It can be determined arbitrarily according to the concentration and quantity, size and price of the device.

However, the ozone water producing apparatus (b) applied to an embodiment of the present invention of FIG. 3 may obtain a high concentration of ozonated water as compared to the conventional ozone water generator (a) of FIG. 1, but is still not sufficient.

Because the narrower the electrode distance d, the faster the current flow rate and the higher the current density (ion density) with the increase of the square wave pulse voltage (Vp), the greater the space charge limiting action. Because.

In the ozone water production apparatus (b) applied to an embodiment of the present invention, two electrodes 11 are charged with charges of reverse polarity (such as discharged or electrolyzed ions and underwater ions) that have been focused by a square wave pulse voltage Vp. (13) The action of densifying these charges (called "space charges"), which are concentrated in a space near them, and rejects charges of the same polarity that are moved next (the coulomb repulsion acts) (space charges). Limiting effect), the current is reduced and thus the ozone generation efficiency is greatly reduced.

In order to solve this problem, the configuration of the ozone water production apparatus (b) applied to an embodiment of the present invention was improved to the configuration as shown in FIG. That is, the positive net electrode 13 and the separator 12 are further provided by additionally placing the external negative electrode 21 on the outside of the negative net electrode 11 and the internal negative electrode 23 on the outside of the positive net electrode 13. Dense charges between the liver and negative net electrodes 11 and the separator 12 rapidly become positive electrode regions B and coulomb forces due to the B-side pulse voltage Vp _B and the A-side pulse voltage Vp _A. By drawing out to the outside of the negative electrode area A, the charge between the two electrodes 11 and 13 is greatly attenuated so that the space charge limiting action hardly occurs, so that a relatively large electric field is generated at the same square wave pulse voltage Vp _B. field, E = Vp / d) was obtained to increase the ozone generating capacity.

In this way, not only the dense charge between the two narrow electrodes 11 and 13 but also ozone water in which ozone is dissolved is accompanied by an ion wind according to the movement of the charge, and thus the external cathode electrode 21 and the internal cathode electrode 23 are easily respectively. That is, the negative electrode water region (A) and the positive electrode water region (B) flow out to limit the turbulence and space charge as well as the thermal decomposition action such as Equation (1), so that ozone is more effectively generated and dissolved.

In this way, the electrodes 11 and 13 are mesh-shaped or three-sized and the electrode interval d is narrowed to effectively generate a high voltage discharge between the two electrodes 11 and 13. That is, discharge is easily generated even at a relatively low electric field in sharp spots (e.g. lightning rods) or small diameters (e.g. thin lines). In particular, when a high voltage pulse is applied on the negative net electrode 11 in the water, oxygen (O ₂ ) is generated as shown in equation (4).

2H ₂ O ------ → 2H ₂ (on negative electrode) + O ₂ (on positive electrode) ------ (4)

Since oxygen molecules have a very low dielectric constant compared to water molecules (the ratio of dielectric constant between water and oxygen is 80: 1), most of the voltage is applied to the oxygen molecules and oxygen molecules are destroyed by discharge, so as shown in Eq. (5) (O) is made.

The baby oxygen again combines with the oxygen molecule (O ₂ ) as in Equation (6) to form ozone (O ₃ ). Compared to direct current power, alternating current power, and other power sources such as pulse and high frequency power, the voltage rose time can be controlled very short. It can cause instantaneous high voltage discharge with power and can cause high voltage discharge with instantaneous power with low power, which is very effective and economical.

The details thereof will be explained in the following pulse power applying means.

In this case, when the electrodes 11 and 13 are mesh-shaped or fine stripe-shaped, the thickness or spacing of the lines, and the width of the stripe are the shape or size of the applied voltage or the generated ozone concentration. It can be adjusted according to the quantity, life of electrode and device price.

This is because an expensive platinum group alloy (Pt + Pd) is used as the electrode material. However, in case of a small device which is inexpensive and does not require long life, or can be frequently changed to a short cycle life, stainless steel is used. It is also possible to use metals or alloys of other forms or materials.

In addition, the separator 12 has a good electrical conductivity and does not mix water between the two regions (A) and (B), and a conventional ion exchange resin system may be used, but a cloth having a large porosity Or resins or ceramics may also be used.

② Form, period and application means of pulse power supply

As a power source to be applied to the conventional ozone water generator (A), it was confirmed that the use of a square wave pulse power supply (FIG. 4) (FIG. 5) can effectively generate underwater discharge and electrolytic action.

This is because the instantaneous supply of the current (or power) several times larger than the pulse current by applying the pulse waveform increases the effective discharge generation and the electrolytic efficiency while lowering the overall average power than the pulse voltage.

On the other hand, in the case of the pulse voltage, the power P _c is expressed as in Equation (7), but in the case of pulse power P _p as shown in FIG. 4, it is represented as in Equation (8).

P _dc = VIt ---------- (7)

P _p = V _P I _P t _P --------- (8)

Where t _P = t _on + t _off . In the case of pulse power P _c, t (voltage application time) is fixed and only V (applied voltage) is variable, so I (applied current) is automatically dependent (fixed at the power plant), but in the case of pulse power P _p , V _P and I _{By setting P} to the maximum (about twice as large as V and I of the direct current) and by varying t _P appropriately, large instantaneous power can be obtained, and the ozone concentration of the output water can be arbitrarily adjusted by easily changing the applied power to t _on . There is an advantage.

In order to generate such an effective voltage waveform V _P , an electronic circuit as shown in FIG. 7 may be used. That is, the AC power source (ac) is converted into a proper voltage using a transformer (LT), rectified through a rectifier (R), and smoothed by a smoothing capacitor (Cf), and a proper period (t _P = t _on + t _off) . When the DC voltage is pulsed by the semiconductor switching power control devices Tr and IGBT by a trigger circuit T that can trigger _{on a} t _on or t _off period), the square wave pulse voltage Vp as shown in FIG. Is generated. At this time, if the bulky capacitor Cf, which is relatively bulky and expensive, is removed, an output voltage waveform Vpac as shown in FIG. 5 is generated, and these pulse waveforms may be used as a power source of the ozone water production apparatus (I) of the present invention.

However, in the high concentration ozone water production apparatus (C) of the present invention, three power sources (V _G , Vp _A , Vp _B ) are required, and in this case, V _G , Vp _A, and Vp _B each have a waveform as shown in FIG. 8. Voltage can be used. However, for more effective high voltage discharge and electrolysis, Vp _A and Vp _B and V _G are alternately applied as shown in FIG. 9, or V _G is continuously applied as shown in FIG. 12, but Vp _B and Vp _A are alternately applied. That is, the case of the power supply which may perform sequence control is more effective.

At this time, the power supply circuit diagram for generating Vp _A , Vp _B and V _G is shown in FIG. 11, and the basic operation principle is the same as that of FIG. 7, but using one low voltage transformer (LT) and configuring three pulse generation circuits in series. By appropriately time-controlling the trigger circuit T, pulse voltages as shown in FIGS. 8, 9, and 10 can be generated.

In addition, the waveform width (magnification ratio of the waveform <duty rate>: t _on and t _off ) of the pulse power supply effective in the present invention is very easy and effectively output ozone concentration by controlling and adjusting the signal wave of the trigger circuit T appropriately. Can be adjusted.

At this time, the voltage Vp _A or Vp _B applied between the voltage V _G applied to the internal mesh electrodes 11 and 13 and the external plate electrodes 21 and 23 is the generated ozone water capacity, the required ozone concentration, and the electrodes 11. (13) (21) (23) can be set to the appropriate voltage value according to the size and spacing (D, d), and the values of V _G and Vp _A and Vp _B are usually about 20 ~ 1000V. Can increase or decrease. In other words, in the case of high purity pure water, a higher voltage is required, and a smaller voltage may be used in a micro device.

In addition, although shown as a square wave in Figures 8 and 10, the pulse generated in the actual semiconductor power circuit is shown as a waveform with a slight transient (exponential rising and falling, and over and / or under shoots), The duty rate of the pulse can be changed to the optimum condition according to the shape and size of the electrode and the output ozone water capacity. Experimental results show that t _on = 10 ^-2 ~ 10 ⁴ s (sec), t _off = The range of 10 ^-3 to 10 ² s (seconds) is relatively effective, but can be increased or decreased depending on the needs and purposes.

③ Electrode Material Crystal

In general, ozone water generator (A) uses pure platinum (99.9%) as the positive electrode (1) (or (3)) material. Therefore, when high current is supplied to increase the concentration of generated ozone, electrode material is made of pure platinum. There is a problem that the life of the electrode 1 (or (3)) is shortened by separation and precipitation in the water.

This problem is caused by using platinum alloy (Pt + Pd) formed by mixing palladium (Pd) with platinum (Pt) in an appropriate amount (0.1 to 15 wt%) as the counter electrode material to electrode 1 (or (3)). Even if a high voltage of 10 OV or more is applied, separation of the electrode is greatly reduced and the service life is extended to more than 4,000 hours.

Therefore, in the case of the positive electrode 13 or the external positive electrode 23 which directly generates ozone, it is very useful to form the above-described palladium alloyed platinum material. However, when the amount of ozone required is very small or the life may be short, stainless steel or another type of metal or alloy material of low cost may be used for the positive electrodes 13 and 23, and the negative electrodes 11 and 21 may be used. In this case, it is effective to use materials such as stainless steel.

In addition, in the case of applying the pulse voltage in this way, even when the ferroelectric material having a very high dielectric constant (relative dielectric constant, ε _r ) is coated on the metal electrode, the electrode material has little precipitation consumption. Because the precipitation consumption of the electrode is proportional to the direct current (I) in Faraday's precipitation law, it is possible to reduce the deposition consumption of the electrode by making the DC current fraction very small in the case of pulse voltage.

In this case, a relatively high frequency with a small ratio of pulse voltage becomes effective, and the relative dielectric constant of the ferroelectric is more effective than the relative dielectric constant of water (ε _r = 80) and the thinner ferroelectric layer, and also the appropriate size on the electrode. The irregularities of are effective in generating discharge and electrolytic action.

In addition, the same effect can be obtained by filling ferroelectric pellets partially or entirely between the internal and external electrodes D and d.

④ Characteristic control of additive ozone water and additive control

When the power source (Figs. 8, 9 and 10) of the appropriate type is applied to the apparatus for producing high concentration ozone water (C) of the present invention, and the appropriate voltage (or current) is set and operated, the ozone water in the anode discharge pipe 18 in the region B is operated. Is discharged, and part of the supply water is discharged from the negative electrode discharge pipe 16 in the area A. However, since the negative net electrode 11 and the positive net electrode 13 are in the form of a net electrode in structure and (D)> (d), the negative net electrode 11 and the positive net electrode 13 are larger in the internal negative electrode area A 'and the internal positive electrode area B'. The electric field strength (E = V _G / d) causes strong partial discharge and electrolytic action on the negative net electrode 11 and the positive net electrode 13, resulting in a very strong electrophysicochemical reaction. As shown in the following equations (9) and (10), strong oxides such as ozone (O ₃ ), oxygen (O ₂ ), oxygen (O) and secondary hydrogen peroxide (H ₂ O ₂ ) are produced very effectively.

6H ₂ O -------- → 6H ₂ + O ₂ + O ₃ + O -------- (9)

H ₂ O + O -------- → H ₂ O ₂ -------- (10)

At this time, the underwater anions (eg Cl ⁻ , SiO ₂ ⁻ , SO ₃ ^−, etc.) in the internal negative electrode region A 'are moved to the internal positive electrode region B ′ by electrostatic force (Coulomb attraction). is moved to the ^- (meneral metal ion such as ^{Ca ++, Fe ++, Mg ++} , Cu) the number of electrodes inside the negative region (a cationic water was on), number of electrodes both on the same principle internal area (B), Mutual ion separation also occurs.

In addition, when an appropriate voltage is also applied to the external cathode electrode 21 and the internal cathode electrode 23, the respective ions in the internal negative electrode area A ′ and the internal positive electrode area B ′ are respectively negative electrode area ( A) and the positive electrode water region B are discharged again and are discharged through the negative electrode discharge pipe 16 and the positive electrode discharge pipe 18, respectively.

Therefore, the positive water, which is output water on the positive electrode discharge pipe 18, is ozone-containing acid water (a large amount of O ₃ and a small amount of O ₂ , O, H ₂ O _2, etc.) containing ozone acid water (anion). Water), and the cathode water which is the output water of the negative electrode discharge pipe 16 is discharged from alkaline water (water containing a lot of cations).

The ozone water (O _3, O _2, O, H ₂ O _2, etc.) and ion concentration containing a lot of ozone in the discharged water are the magnitude (V _G , Vp _A , Vp _B ) or period (especially t _on ) of the applied power source. By controlling the back manually and automatically (using an automatic control circuit, etc.), the back light can be easily adjusted. It can also be adjusted by varying the size of the electrodes 11, 13, 21, 23, the electrode spacing d or the water flow width D.

On the other hand, a substance containing or generating Cl ^−, for example, when tap water, salt (NaCl), potassium chloride (KCl), etc., is present in the feed water, a strong oxidizing substance and ionic concentration may increase.

^{NaCl ------ → Na + + Cl -} ------- (11)

^{KCl ------ → K + + Cl -} ------- (12)

In other words, NaCl water enters the mutual bonding force is weak (in the underwater search is 1/80) lower applied voltage in the above formula (11), Na ⁺ or K ^+, such as 12, and Cl ^- is easily decomposed with Na ⁺ Or K ⁺ moves to the negative electrodes 11 and 21, and Cl ⁻ moves to the positive electrodes 13 and 23 so that the current and the ion concentration can be greatly increased.

At this time, particularly, the positive electrode region B and the internal anode region B 'contain a large amount of Cl ⁻ , and as shown in Equation (13), OH generated by electrolysis of H ₂ O combines with Cl. As shown in Eq. (14), HClO (strong oxidizing material) is generated, so that the strong oxidizing material containing a lot of HClO (a large amount of HClO and O ₃ , and a small amount of H ₂ O ₂ , O, O _2, etc.)

It can be created to be more versatile.

H ₂ O -------- → OH + H -------- (13)

OH + Cl ------- HClO --------- (14)

In this case, the water supplied to the water supply pipe may be mainly tap water or ground water, but various aqueous solutions (such as distilled water or reagent dissolved water solution) may be used depending on necessity and purpose. In addition, the additives added to this aqueous solution or water (NaCl, KCl, etc.) vary somewhat depending on the type, required ion concentration, and application conditions, but it is effective and economical to add them in a weight ratio of about 0.01% to 1%. Experimental results were confirmed.

In the case of a conventional ionized water device, acidic water having a pH of about 4 to 6 and alkaline water having a pH of about 8 to 10 are usually discharged from a positive electrode discharge tube and a negative electrode discharge tube, and are mainly used for drinking of alkaline water.

In addition, in the case of the highly concentrated acidic electrolyzed water developed in Japan recently, a flat plate electrode coated with platinum (Pt) on titanium (Ti) on both sides of the ion exchange resin is applied to the applied voltage. Normal ionized water device using only the principle of electrolytic action (electrolysis occurring at about 3V or more) by using a direct current or a pulse current of about 10 to 20V (the voltage becomes 20V or more, and the life of the electrode is drastically shortened.) It has the same structure as that, and high concentration of ionized water of pH 2-4 and pH 10-12 is discharged from the positive and negative electrode discharge pipes. In this case, a strong acid water device with a pH of 2-4 is currently being developed for the purpose of disinfection and sterilization, but since the concentration of acid is too high, it contains only strong oxidizing material (HClO) and almost no ozone, so ozone water can be easily applied. There is a problem that there are many restrictions, such as not for performance.

⑤ Neutral water production means

In the high concentration ozone water production apparatus (C) of the present invention, the positive electrode discharge pipe (18) emits strong acidic water including a strong oxidizing material, and thus, in the case of the conventional ozone water generator (A), its characteristics are different from ozone water, which is the discharge water. In other words, while the discharge water of the conventional ozone water generator (a) is pH7, the discharge water of the high concentration ozone water production apparatus (C) of the present invention becomes a strong acidic water of pH 2 ~ 4 may have advantages and disadvantages and limitations according to the performance characteristics. .

Therefore, in the case of the high concentration ozone water producing apparatus (C) of the present invention, in order to solve this problem, negative electrode water (strong alkaline water) W _A discharged from the area A and positive electrode water discharged from the area B (strong acidic water) as shown in FIG. 12. (W _B ) by mixing the strong acid water and the strong alkaline water discharged from the two discharge pipes (16) (18) in the neutral water production means (M) by applying a neutral water of pH7 as in the first water supply pipe (6) ( W _C ).

As such, the neutral water (W _C ) becomes a neutral water of pH 7, but a large amount of oxides (mainly O ₃ , H ₂ O ₂ , HClO, etc.) generated by discharge and electrolysis are somewhat reduced as shown in FIG. As it remains in neutral water, sterilization and disinfection effect is sufficient. (In case of 0.3ppmm, the bactericidal power of E. coli kills 99.9% for 10 seconds.) As a means of generating neutral water, it is only necessary to install a mixing tank. Apparatus such as a suitable method may be further used. That is, depending on the amount and pH of the mixing W _A or W _B , W _C can be arbitrarily adjusted to pH as well as neutral acid water or weakly alkaline water.

On the other hand, the neutral water W _C is finally produced in the same functional and functional effect as the ozone water produced by Patent No. 54450, "Ozone Generator in Liquid" (92.4.24).

That is, the structure (a) of Patent No. 54450 "Ozone Generator in Liquid" is that when the ion separation membrane 12 is removed from the ozone water production apparatus (b) of the present invention, the structure is completely identical, and the present invention This is because the high concentration ozone water production system (C) is an improved version of the ozone water production system (B).

Accordingly, the ozone water production device (b) or the high concentration ozone water production device (c) of the present invention has the same function and function in place of my own patent No. 54450, "Ozone Generator in Liquid," which is the same for the same purpose or application. In addition to being able to be applied, the characteristics of the effluent are also higher concentrations of ozone water (including large amounts of O ₃ and other O, H ₂ O ₂ , O _2, etc.) and high concentrations of strong oxidizing dissolved water (large amounts of HClO and O ₃ , Trace amounts of H ₂ O ₂ , O, O _2, etc.) are obtained and can be used to adjust to any value between pH 2-12.

The improved high-concentration ozone water production apparatus (C) of the present invention shows the ozone water generation characteristics as shown in FIG. 13 when using tap water, and a very high oxidizing substance as shown in FIG. 14 when a small amount of salt is mixed with tap water. The containing water is produced, which not only has the advantage of generating 3 times and 15 times stronger ultra high concentration water, respectively, than that produced by the conventional ozone water generator (A), as shown in FIG. It is possible to separate and discharge strong acidic water (W _B ), pH 2 ~ 3, strong alkaline water (W _A ) and neutral water (W _C ), respectively.

In the high concentration ozone water production apparatus (C) of the present invention, ozone water containing a large amount of ozone is made by supplying water not containing ordinary Cl ⁻ to the water supply pipe 6, and water containing a large amount of Cl ⁻ (salt water, etc.). By supplying water), steel oxide-containing water containing a large amount of HClO and O ₃ can be obtained, and thus it can be used for more various fields.

The neutral water (W _C ) thus obtained is treated with water and sewage, sterilization of meat and food, sterilization of meat or food, sterilization of agricultural products or fishes using sterilization, deodorization, decolorization, strong oxidation, etc. Industrial wastewater, industrial wastewater treatment, hazardous organic gas treatment, pesticide substitutes, and during pharmaceutical or food manufacturing processes, and more recently, medical devices (e.g., disinfection and disinfection of hands such as doctors, hospital personnel and restaurant food manufacturers, It can be applied to various fields and applied to various fields such as doctor's clothing, dental oral disinfection and washing water).

In addition, since some of the additives (KCl or NaCl, etc.) initially introduced from the water supply pipe 6 are decomposed by high voltage discharge or are electrolytically separated and ionized, the neutral water W _C is caused by these additives. Salts, etc.) can also be applied in a variety of applications because it is solved.

In addition, strong acidic water (W _B ) can be used for sterilization and disinfection of various bacteria as well as fungus, moss, algae, and pest control, so it does not cause secondary pollution. Oral disinfection and rinsing in dentistry, gastric or intestinal lavage, bacterial infection walls in hospitals, etc.

On the other hand, strong alkaline water (W _A ) can be applied to drinking water of humans or livestock for special purposes, or specially grown water for plants (eg hydroponic or irrigation water), and neutralizing strong acidic water, neutralizing acidic soils, and acidified nutrient solution. It can be used for the purpose of neutralizing the number of cultivation (hydroponic cultivation, etc.), and it can be widely used for various purposes such as water for promoting germination and growth of plants.

In addition, in the ozone water production apparatus (b) of the present invention and the high concentration ozone water production apparatus (c) of the present invention, as shown in FIGS. 13 and 14, some oxides (O ₃ , H ₂ ) are also found in the strong alkaline ionized water (W _A ). O ₂ , HClO, etc.) can also be contained in a small amount, so that it can be applied to the target water even more as sterilized water.
