[0002]

2. Description of the Related Art It is known that water is oxidized and reduced to change its potential and the water is used in various industries, and an apparatus therefor has been put into practical use.

The water obtained by this device is useful for maintaining the freshness of crops in agriculture, pesticide-free cultivation, and improving the efficiency of cultivation, and in the fishery industry, maintaining freshness of fish and shellfish.

In addition, in the brewing industry such as alcoholic beverages, it improves quality and productivity, and in the fields of medicine and pharmacy, it helps improve drug effects and preventive medicine.
In industry, it is effective to prevent oxidation by making the industrial water oxygen-free water. In addition, it has a wide range of use as it is useful for various environmental improvements.

If the treated water whose redox potential is changed as described above is one that has also been sterilized by removing organic substances, inorganic substances and bacteria, the application will be further expanded.

In order to change the oxidation-reduction potential of water, it is also known to change it by sending air into the water or irradiating the water with a sound wave.

It is also known that the above-mentioned change in redox potential also occurs by injecting N ₂ gas by an aeration method. Figure 4 shows the dissolved oxygen (D
O) shows the change in amount. The horizontal axis is time (unit is 1 hour), the vertical axis is dissolved oxygen (DO) amount, and the unit is ppm. Further, FIG. 5 shows changes in the redox potential in that case, the horizontal axis represents time (unit is 1 hour), and the vertical axis is redox potential (unit is × 100 mV). In both figures, N _{2 at} point A
The injection of gas was started, the injection was stopped at point B, and then the container was left open as it was. As can be seen in both figures, changes in the amount of dissolved oxygen and changes in the redox potential occur when N ₂ gas is injected into water by the aeration method in an open state, but the amount of change is very slight. Is.

It is shown in.

In both figures, the injection of N ₂ gas is started at point A, the injection is stopped at point B, and then the container is left as it is in an open state. In FIG. 6, the horizontal axis is time (unit is 1 hour), the vertical axis is dissolved oxygen (DO) amount, and the unit is ppm. As shown in FIG. 6, the change in the amount of dissolved oxygen (DO) decreases to near zero. FIG. 7 shows the redox potential of water in this case, the horizontal axis represents time (unit is 1 hour), and the vertical axis is redox potential (unit is × 100 mV).
Is. As can be seen from this figure, the oxidation-reduction potential decreases immediately after the treatment, but it returns to the original value when left standing and rises further, which is a unstable state.

Etc. are removed. Since the ceramic filling contact device b following the filtration device a through the adjusting valve V ₃ is filled with the powdered ceramic whose redox potential is adjusted, the redox potential of water is adjusted to deodorize. The treated water is sent to the next ultraviolet irradiation device c.

Further, in the ultraviolet irradiation device c, the water is sterilized by being exposed to the ultraviolet light by the ultraviolet generator c ′, and the water which has been subjected to the above treatment is returned to the closed tank 17 through the adjusting valve 6.

FIG. 3 shows the result of water treatment by the apparatus embodying the present invention. The figure shows changes in the redox potential, the horizontal axis represents time (unit is 1 hour), and the vertical axis is redox potential (unit is × 100 mV). In the figure, point A is N
₂ gas starts to be injected and N ₂ gas is stopped to be injected at point B,
The closed tank 17 is left as it is for a predetermined time while the N ₂ gas is retained as the gas retention chamber 15 in the upper portion while maintaining the closed state. Thus, the redox potential lowered at point B slightly increases with time,
It can be said that it is almost in a stable state. The dissolved oxygen (DO) amount does not increase because the stable state is obtained as shown in FIG. 6 above.

The type of gas supplied to the gas retention chamber was N ₂ gas in the present embodiment, but by selecting the type of gas, a desired amount of water from highly oxidizing water to highly reducing water can be obtained. It is possible to obtain

Further, in the present embodiment, the redox potential instruction adjuster 11 controls the output amount of the water gas mixing pump P ₃ , the injection amount of air or oxygen to be injected, and the irradiation amount of the sound wave to be emitted. Although configured, this combination is arbitrary depending on the purpose and the like, and can be changed in any way.

[0043]

As described above, according to the present invention, in a water oxidation-reduction potential control device using a closed tank, a composite sound wave generation jet type water gas mixing device is used to inject air or oxygen and generate a sound wave. Irradiation is performed at the same time to reduce the oxidation-reduction potential, N ₂ gas is retained in the gas retention chamber in the tank and dissolved in water, and a device for filtering and sterilizing water in the tank is provided. Thus, it is possible to obtain treated water having a desired redox potential and having a small amount of dissolved oxygen, in which organic substances, inorganic substances and bacteria are also removed.

Further, since the composite sound wave generating jet type water gas mixing device is used in the closed type tank, the safety is high.

Further, since the N ₂ gas is retained in the closed tank, the gas pressure can be increased and therefore the gas solubility in water can be increased.

Irradiation of sound waves in the composite sound wave generating jet type water gas mixing device is also effective in increasing the solubility of N ₂ gas in the gas retention chamber in water.

The gas in the gas retention chamber has a gas refining function,
Impurity gas generated from water is removed, and only highly pure gas is dissolved in water at all times, so that treated water of high quality can be obtained.

Since the composite sound wave generation jet type water gas mixing device can control the injection amount of water, the solubility of gas such as air or oxygen in water can be controlled. Therefore, it is also possible to easily control the redox potential.

The jet-type mixer of the composite sound wave generation jet-type water-gas mixer has an effect of activating water because it can reduce clusters (molecular groups) of water.

The numerical value of the redox potential can be arbitrarily controlled to a desired numerical value by the redox potential detection sensor and the redox potential instruction adjuster.

Furthermore, since the oxidation-reduction potential of water is changed without using chemicals, the solubility of gas in water is relatively small except for a part, so that the change in oxidation-reduction potential is also due to chemicals. Small in comparison. Therefore, the potential can be finely adjusted. In addition, it becomes possible to freely sterilize and proliferate microorganisms, which must be chemical-free, and can promote the oxidative decomposition of organic substances, and it is possible to use chemical-free chemicals for livestock production, hydroponic cultivation, sprouts production, mushroom cultivation, etc. This enables healthy growth of plants and animals. Even when used in natto, liquor, beer, etc., it promotes the generation of these fungi, prevents the product from spoiling after production, and is effective for long-term storage. Furthermore, the weight gain rate of animals and plants, feed efficiency, and fertilizer efficiency are improved, and productivity is improved.

By selecting the type of gas, it is possible to obtain treated water of high quality, from safe oxidizing water to highly reducing water, safely and inexpensively.

Since the sterilizer used in the present invention is a combination of a filter device, a ceramic method and an ultraviolet method, it is effective not only for removing organic substances and inorganic substances and for sterilizing bacteria but also for deodorizing. There is something.

In addition, the device is easy to handle, does not require much time for maintenance, and has the effect of maintaining a healthy and safe living environment.
