Title:
Micro bubble generator
Document Type and Number:
Japanese Patent JP6338518
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a microbubble generator producing with a simple structure, microbubbles whose usage field is expanded.SOLUTION: A liquid 1 is sent from a lower part of a storage tank 2 through a circulation tube 10 to a two-fluid nozzle 11, and on the other hand, return gas and fresh gas are joined together and sent from a Y joint 8 through a first valve 9 to the two-fluid nozzle 11. In the two-fluid nozzle 11, the liquid, air and gas are mixed to form a gas-liquid mixing fluid, and the gas-liquid mixing fluid pushed out from a compression liquid pump 12 is put into a pumping tube 13, and strongly generates cavitation when becoming a supersaturated state by returning to a stationary state so as to deposit dissolved air and gas. At that time, the gas-liquid mixing fluid is boiled, and is guided as it is to an appropriate clearance by a second valve 14 and returned to a normal pressure so as to bring dissolved gas into bubbles to discharge into the storage tank 2. A constant quantity of microbubble is discharged by guiding to a porous filter 15.SELECTED DRAWING: Figure 1
