微細気泡発生装置
Document Type and Number:
Japanese Patent JP6393152
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fine bubble generator which enables even a liquid injected first after a start-up to contain a large amount of fine bubbles.SOLUTION: The fine bubble generator includes a liquid introduction pipe 24, a gas injection part 4 for injecting a gas into the liquid introduction pipe, a booster pump 21 for pressurizing and pressure-feeding a gas-liquid mixture formed by introducing a gas into the liquid in the liquid introduction pipe by the gas injection part, a dissolving tank 1 for pressure-dissolving the liquid and the gas in the gas-liquid mixture fed by the booster pump, a liquid leading-out pipe 41 for leading out the liquid in the dissolving tank, a fine bubble generation nozzle 43 for generating fine bubbles in the liquid in the liquid leading-out pipe and injecting the liquid containing the fine bubbles, a check valve 23 provided in the liquid introduction pipe and configured to permit the flow of the liquid from a liquid supply source to the booster pump while blocking a flow in a reverse direction, a solenoid valve 42 for opening/closing the liquid leading-out pipe, and a control unit 5 for controlling the solenoid valve and closing the solenoid valve when the booster pump is stopped.SELECTED DRAWING: Figure 1
