OZONOUS WATER GENERATING SYSTEM

摘要

PURPOSE:To discharge ozonous water with different concn. from a cock without controlling an ozone gas generating part by connecting two or more reaction cylinders in series so as to bring ozone gas and water to a countercurrent contact state and circulating ozonous water between storage tanks. CONSTITUTION:Ozone gas enters the reaction cylinder 5 rearmost in the flow direction of ozonous water among two or more reaction cylinders connected each other to come into contact with ozonous water. The residual ozone gas is guided to the reaction cylinder 5' on this side to come into contact with water or ozonous water and ozonous water with high concn. is obtained from one reaction cylinder. Further, by recirculating the ozonous water of the storage tank provided to the lower part of the reaction cylinder to storage tanks B10', A10, ozonous water with high concn. can be obtained. Therefore, ozonous water with at least three or more kinds of concns. is obtained by changing over a valve.
