Abstract

The invention relates to an ozone water production apparatus capable of producing ozone water with a highly versatile and simpler configuration and further producing ozone water having a higher concentration with decomposition by heat suppressed. O₂ gas and N₂ gas are introduced into an ozonizer (2), and ozone is generated in the ozonizer (2). The generated ozone is mixed with supplied water, and thereafter the mixture is introduced into a circulation pump (4) to dissolve ozone in water. A pipe from the ozonizer (2) is connected to a water pipe connected to the circulation pump (4) using a T-shaped union joint to mix water and the generated ozone gas. Further, the ozone water is heated to a predetermined temperature by a heat exchanger (5a) using hot water as a heat medium.

Claims

1. An ozone water production apparatus for producing ozone water in which ozone gas is dissolved by mixing supplied water and ozone gas, the ozone water production apparatus comprising a positive-displacement pump, ozone gas being dissolved in water by circulating water by the positive-displacement pump and mixing ozone with circulating water.

2. The ozone water production apparatus of claim 1, wherein an amount of circulation liquid by the positive-displacement pump is four times or more a discharge flow rate of produced ozone water.

3. The ozone water production apparatus of claim 1 or 2, comprising a circulation tank for temporarily storing circulation liquid,

wherein a pressure in the circulation tank is held constant at a pressure higher than a normal pressure.

4. The ozone water production apparatus of any one of claims 1 to 3, comprising a heating section for heating a part of circulating ozone water,

wherein a concentration of circulating ozone is made lower than its saturation solubility at a room temperature and higher than its saturation solubility at a predetermined high temperature that is higher than a room temperature, and

supersaturated ozone water having a higher ozone concentration than the saturation solubility at a high temperature is produced by heating part of circulating ozone water by the heating section.

5. The ozone water production apparatus of claim 4, wherein the heating section is a heat exchanger using hot water as a heat medium.

6. The ozone water production apparatus of claim 4 or 5, wherein the heating section raises a temperature of ozone water to a predetermined temperature in a short time of 8 to 10 seconds.
