FINE BUBBLE GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To solve such a problem that a high pressure large-sized pump is required because air and hot water sucked in a pump is finely divided and mixed by a high pressure jet nozzle in a conventional bubble generator and stable fine bubbles can not be generated because a shuttle valve is used in an air suction part. SOLUTION: The fine bubble generation device is constituted so that an air supply part 4 is provided to the supply pipe 3 on the suction side of a circulating pump 2 and is provided to the discharge pipe 8 on the discharge side of the circulating pump 2 while a fine bubble generation part 7 is provided to the water tank discharge part of the discharge pipe 8 and a throttle part 10 is provided to the inflow part of the gas-liquid dissolving tank 9 to mix and dissolve the air in the gas-liquid dissolving tank 9 and the gas-liquid mixed fluid flowing in the gas-liquid dissolving tank 9. By this constitution, air can be dissolved in the fluid in a short time under a low pressure to stably generate fine bubbles.
