FIG. 1 is a schematic explanatory view showing an ultrafine high-pressure ozone gas bubble-containing water production system according to the present invention. FIG. 2 is a schematic explanatory view showing an example of a gas permeation section constituting the system of the present invention.

  FIG. 1 is a schematic explanatory view of the ultrafine high-pressure ozone gas bubble-containing water production system of the present invention, wherein 1 is a pressure cylinder, 2 is a high-pressure ozone generator, 3 is a gas permeation section, and 4 is a regulator (pressure regulator). 5 is an electromagnetic valve, 6 is a pressurized water supply pump (circulation water supply pump), 7 is a water supply pipe, 8 is an ozone reaction tank, and 9 is an air supply pipe.

  The ultrafine high-pressure ozone gas bubble-containing water production system of the present invention comprises a high-pressure ozone gas supply means, a pressure-resistant cylinder 1 filled with high-pressure oxygen, and a high-pressure oxygen-compatible high-pressure ozone generator 2 that generates high-pressure ozone gas by reacting high-pressure oxygen.

It by an ultra fine high pressure ozone gas bubble-containing water production system characterized by high concentration of ozone-containing water is generated.

[Generation of ultrafine bubbles]
The high-pressure ozone gas is placed on the gas permeation surface as a gas permeable material, penetrates through a nano-porous body that can control the gas permeation amount of high-pressure ozone gas by forming a vent hole with a fine communication hole or a fine direct hole. In the initial stage of the process of generating ultrafine bubbles on the gas permeation surface, it is quickly sheared by the flow of raw material water passing through the water pipe and contained in the raw material water in the form of micro / nano-sized ultrafine bubbles. Specifically, the high-pressure ozone gas that attempts to forcibly permeate by expanding the fine communication holes or the fine direct holes that constitute the nanoporous material is limited in the amount of permeation to the fine communication holes or the fine direct holes. While being gradually permeated into the water, the bubbles that grow on the gas permeable surface are quickly sheared in the initial stage by the water flow passing through the water pipe, so that ultrafine bubbles containing high-pressure ozone gas as raw materials. Contained in water.

[Pressurized fine bubbles]
As a physical property, fine bubbles in distilled water have a potential of about −30 to −50 mV regardless of the bubble diameter, so that the surface of the bubbles is surrounded by anions such as OH ⁻ and the surroundings. In this structure, cations such as H ⁺ (H ₃ O ⁺ ) are covered. Fine bubbles have a larger specific surface area than ordinary bubbles and have a high internal pressure because surface tension acts effectively.

The main element of the present invention is to efficiently improve the surface of the polymer material by increasing the internal pressure of the bubbles by adding ozone having a strong oxidizing ability to the raw water as high-pressure ozone. Ultrafine bubbles made of the high-pressure ozone gas are easily contained in the liquid. The fact that the pressurized fine bubbles are easily contained in the liquid is expressed by the following formula.
w = kP
In this equation, w is the mass of the gas dissolved in the liquid, P is the pressure of the gas, and k is a proportionality constant. From this, it is understood that the mass of the contained gas is directly proportional to the gas pressure. In other words, when a gas is contained in the liquid, more gas is contained in the liquid as the pressure of the gas in contact with the liquid increases.

  In the present invention, an apparatus for producing water containing ultrafine bubbles containing high-pressure ozone gas as a component has an ultrafine bubble of about 200 nm to 5 μm in water when the liquid is water and the gas is high-pressure ozone gas. It is a device that is easily generated, and even if fine bubbles generated in the water are visible, the buoyancy is small and drifts in the water, while ultra-fine bubbles that are not visible are dissolved or mixed in the water. This is a system that generates gas-liquid mixed water containing abundant ultrafine bubbles that stay in water.

[Nanoporous material]
The nanoporous material employed in the present invention is desirably a gas-permeable material capable of controlling the gas permeation amount of high-pressure ozone gas by forming the air holes with fine communication holes or fine direct holes, and is a polymer resin film. It can be said that a breathable film (craze film) formed by forming a craze is a material suitable for functional and ease of handling, but is not particularly limited as long as it is a material that can control the amount of gas permeation. However, it is necessary that the material has ozone resistance or is subjected to ozone resistance treatment. As for the material having ozone resistance, examples of the resin include a fluorine resin, and examples of the metal include stainless steel, Inconel, Teflon, and silicon rubber.

[Craze film]
A craze film, which is one of the nanoporous materials, is a film that has the property of allowing gas to permeate but not liquid such as water or oil. Film. The craze is basically the same as that disclosed in Japanese Patent No. 315658, and generally has a width of 0.5 to 100 μm, preferably 1 to approximately parallel to the direction of molecular orientation of the resin film. 50 μm. The ratio of the number of crazes penetrating in the thickness direction of the film is 10% or more, preferably 20% or more, particularly preferably 40% or more, and penetrating with respect to the number of all crazes. When the ratio is less than the above range, it is difficult to obtain sufficient air permeability. The craze mentioned here includes a surface craze appearing on the surface of the resin film and an internal craze generated inside, and refers to a region having a fine cracked pattern.

[Components of ultrafine bubbles]
In the present invention, the main component is the high-pressure ozone gas generated by the high-pressure oxygen-compatible high-pressure ozone generator that generates high-pressure ozone gas by reacting high-pressure oxygen as the foam component, but nitrogen present in the air depending on the situation By using oxygen, purified carbon dioxide, oxygen or the like alone or in combination, a surface treatment of a polymer material suitable for the material is performed.

  The ultrafine high-pressure ozone gas bubble-containing water produced by the ultrafine high-pressure ozone gas bubble-containing water production system of the present invention has an excellent effect mainly in the following treatments.

[Surface modification treatment]
In the surface modification of the polymer material, the surface is activated, and printing and adhesion are greatly improved. Conventionally, pretreatment with chromic acid has been performed in the plating process of polymer materials for the purpose of decoration and electromagnetic shielding. However, the use of chromium is not preferable in terms of pollution, and surface modification of various polymer materials is required. Ozone has been used for quality.

As an example of the use of ozone, in the semiconductor manufacturing process, in addition to precision cleaning of organic substances adhering to the substrate surface, it is used for CVD (Chemical Vapor Deposition) film forming technology in which an SiO ₂ film is formed with organosilane and ozone. In addition, ozone can be used to form an oxide superconducting thin film. When ozone is used for the surface treatment of the base material and the cleaning of the surface of the silicon substrate, irradiation damage is suppressed as compared with other dry cleaning methods.

  The ultrafine high-pressure ozone gas bubble-containing water production system of the present invention and the generated ultrafine high-pressure ozone gas bubble-containing water have advantages in surface treatment of various materials such as polymer materials and metal materials, as well as dissolution, oxidation, Excellent in various effects such as sterilization, deodorization, bleaching, deodorization, decolorization, and reaction promotion. In fields where ozone gas is used, such as medicine, agriculture, fisheries, environment, water treatment, mining, industry, civil engineering, and construction. In particular, since high-concentration ozone gas-containing water can be obtained, it is expected to be used in water treatment related to wastewater treatment and water purification.
