NOZZLE FOR GAS-LIQUID MIXING, GAS-LIQUID MIXING MECHANISM AND APPLICATION OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a gas-liquid mixing nozzle capable of dispersing gas from the mixture of gas and liquid as fine air bubbles efficiently with a simple structure.;SOLUTION: A gas-liquid mixing mechanism 2 for the gas-liquid mixing nozzle, comprising a circulating pipe 1 having an introducing port 11 of gas-liquid mixed fluid and an exhausting port 12 and a gas-liquid mixing mechanism 2 which is fitted airtightly/liquid-tightly in the circulation tube, includes: an inner part introducing port 21a introducing gas-liquid mixed fluid; an agitating mixing means agitating and mixing the gas-liquid mixed fluid; a gas-liquid agitating and mixing part 21 having an exhaust port exhausting agitated and mixed fluid; a flow rate adjusting part 22a regulating the flow rate of the fluid; and a gas-liquid mixture preparation part 22 having a pressure change part 22b continuously changing the pressure of the fluid whose flow rate is regulated, and making the gas in the gas-liquid mixed fluid as a gas-liquid mixture with fine air bubbles dispersed in the liquid.;COPYRIGHT: (C)2012,JPO&INPIT
