Description of the Related Art Ozone has a strong oxidizing power due to the action of atomic oxygen generated in the process of self-decomposition, and ozone sterilization utilizing this property has no danger of remaining because ozone itself becomes oxygen after decomposition. Has the advantage of Previous studies on the bactericidal action of ozone in water have required ozone water in a concentration as high as possible in order to reduce the ozone concentration by being consumed by the decomposition of organic substances mixed therein.
If high-concentration ozone water can be produced, a large amount of ozone water can be produced by appropriately diluting the high-concentration ozone water. Further, for example, if the device capable of generating high-concentration ozone water and the device capable of generating only low-concentration ozone water have the same size, the ozone water generating device can be made compact. Conventionally, cold salt water for fresh fish 3.
5%, 0.9% cold salt water for meat, dip treatment for several minutes to several tens of minutes in cold water for vegetables, and use the air pump to introduce ozone into cold water or cold salt water. As a result, fresh food is sterilized to maintain its freshness. Further, there has been proposed a device for injecting ozone air generated from an ozone generator into a water tank in a state of being mixed with cooling water ejected from a water injection pipe, without using an electromechanical means (actually, developed 60-). 2197
No. 9). However, in such a conventional configuration, there are problems that the device becomes large-sized, there are many failures, and there is a drawback that ozone water of high concentration cannot be obtained.

示す。(Embodiment 3) When a voltage is applied between the nozzle and the ground electrode during bubbling by the process according to the method used in Embodiment 1 using a single nozzle, the bubbles become finer as the applied voltage rises. The electrostatic bubble generation phenomenon was applied to ozone gas absorption, and the experiment of generating high-concentration ozone water was carried out to find the relationship between the ozone water concentration and the applied voltage, and the relationship between the ozone water concentration and the gas flow rate. Oxygen is used as the ozone source gas, and ozone generated from the ozonizer flows out as bubbles from the nozzle into the distilled water in the absorption tower. Here, a DC voltage that makes bubbles fine is attached to the nozzle body, and the inner diameter is 30 mm and the outer diameter is 45 m, which is installed above and facing the nozzle body.
m was applied between the ring-shaped ground electrodes. The absorption tower is made of transparent acrylic resin having a side of 60 mm and a height of 200 mm. Here, the dimension A by which the stainless steel injection needle 21 projects from the glass tube 20 is preferably 0. This is because if the tip of the needle 21 projects from the glass tube 20, it is difficult to make bubbles fine. A schematic cross-sectional view of the nozzle used is shown in FIG.
Shown in. Nozzle 4 has an inner diameter of 0.25 mm and an outer diameter of 0.5 mm
The tip of the stainless steel injection needle 21 is flatly ground, and the tip is removed for insulation to cover it with the glass tube 20. The glass beads 16 were filled in the nozzle so that pressure equilibrium was reached in a short time and fine bubbles were continuously generated. 1

By increasing the applied voltage, it was possible to obtain a concentration of ozone water up to about 10 times as high as when no voltage was applied. In addition, it was observed that the flow of distilled water from the nozzle electrode to the ground electrode was caused by the electrohydrodynamic flow due to the application of voltage, and that particularly fine bubbles convection along with this flow, and the residence time of bubbles in distilled water was observed. increased. If the applied voltage is too high, ozone is decomposed by corona discharge at the nozzle tip, so 1.7

明の装置を適用することができる。(2) Effect of gas flow rate on ozone water concentration From FIG. 4, it was confirmed that the ozone water concentration did not increase at an applied voltage of -1.75 kv or more at a gas flow rate of 1.5 ml / min. FIG. 5 shows the results of changing the gas flow rate with the applied voltage set to 0 kv and -1.75 kv. From FIG. 5, it can be seen that the ozone water concentration increases as the gas flow rate increases. Further, FIG. 6 shows the ratio of the ozone water concentration C O when no voltage is applied to the ozone water concentration C when a voltage is applied, C / C O. From this, it was found that C / C O decreased as the flow rate increased. From the above, in order to efficiently generate high-concentration ozone water, reducing the amount of gas passing through one nozzle and increasing the amount of gas flowing into the ozone absorption tank at a certain time increases the high concentration. It can be said that the ozone water is obtained. It is considered effective to use a plurality of nozzles as a means for that. In the above embodiment, the device for generating ozone has been described, but the device of the present invention can be applied as a device for dissolving a gas other than ozone, for example, a gas such as nitrogen (N 2 ) or hydrogen (H 2 ). .
