FINE BUBBLE-CONTAINING LIQUID GENERATING APPARATUS

摘要

A fine bubble-containing liquid generating apparatus includes a generator including a mixing nozzle for leading in gas and pressurized liquid and a fine-bubble generating nozzle for discharging liquid that contains fine bubbles of the led-in gas, a circulation passage for returning liquid discharged from the fine-bubble generating nozzle to the mixing nozzle in a state in which the liquid is isolated from outside air, an extraction part for extracting, as a fine-bubble containing liquid, part of liquid circulating through the generator and the circulation passage, and a replenisher for replenishing the circulation passage with liquid to maintain the amount of liquid circulating through the generator and the circulation passage. With this configuration, it is possible to continuously generate a fine-bubble containing liquid that contains a high density of fine bubbles.
