Abstract

PURPOSE:To produce concd. ozone water by providing an ozonizer for supplying gaseous ozone to an ejector, a first-stage pump for pressurizing water, a second- stage pump for repressurizing a gas-liq. mixture and forced-feeding a part of the mixture into the ejector, etc. CONSTITUTION:The gaseous ozone generated by an ozonizer 1 is brought into contact with water by using the ejector 8, returned between the first-stage pump 2 for pressurizing water and the second-stage pumps 3 and 4, and repressurized. Consequently, cavitation is not caused in the second-stage pumps 3 and 4, and the service life of the second-stage pumps 3 and 4 is prolonged. Since the gaseous ozone is dissolved into water under pressurized conditions, concd. ozone water can be produced without being affected by the performance of the ejector 8. Furthermore, since the operation is performed under pressurized conditions, the partial vapor pressure of ozone is lowered, and the gas-liq. contact time can be reduced.

This pressurized dissolution tank 5 has an optimum contact time (1 to
5 minutes), the ozone gas is dissolved in water under pressure to a level close to saturation, and then normally passes through the flow rate regulating valve 26 and enters the gas-liquid separation tank 6. Since the inside of the gas-liquid separation tank 6 is at normal pressure (atmospheric pressure), the ozonated water becomes saturated at normal pressure, and the supersaturated portion is separated as exhaust ozone gas, and the ozone is decomposed in the exhaust ozone decomposition device 9. It is then released into the atmosphere. The ozonated water passes through the stop valve 32 and enters the washing water tank 7. At this time, by adjusting the opening degree of the flow rate adjustment valve 27, the cleaning water tank 7 can be
It becomes possible to control the ozone water concentration inside the tank.

Further, after leaving the pressurized dissolution tank 5, the pressurized saturated ozone water passes through the stop valve 33 (at this time, the valves 26, 27 and 32, 56 are fully opened), and the pressurized saturated ozone water flows into the washing water tank 7.
As the pressure inside the tank returns to atmospheric pressure, supersaturated ozone gas is generated as fine bubbles in the cleaning tank, and the bubbling effect makes it possible to increase the cleaning power.

Further, the pressurized dissolution tank 5 can be omitted when there is a means to maintain the gas-liquid contact time, such as when the piping is long. Furthermore, cleaning, sterilization, and sterilization may be performed by directly spraying pressurized ozone water onto the object to be cleaned without providing the cleaning water tank 7.
