SOLUBILITY REGULATING METHOD OF CONTINUOUS WATER PASSING-TYPE GAS-DISSOLVING APPARATUS AND CONTINUOS WATER PASSING-TYPE GAS-DISSOLVING APPARATUS FOR EXECUTION THEREOF

摘要

PROBLEM TO BE SOLVED: To freely regulate the solubility of gas into a liquid in a continuous water passing type gas dissolving apparatus. ;SOLUTION: A raw water supply route 3, a treated water emitting route 4 and a circulating route 7 mixing gas with the water discharged from the gas dissolving treatment tank 2 through a gas-liquid mixing apparatus 6 to return the water-gas mixture to the treatment tank 2 are provided to the gas dissolving treatment tank 2. The flow rate of the raw water supply route 3 and that of the treated water emitting route 4 are made almost same and the flow rate ratio of the raw water supply route 3 or the treated water emitting route 4 and the circulating route 7 is regulated to regulate the gas solubility of the treated water in the treatment tank 2.;COPYRIGHT: (C)1998,JPO
