摘要

PURPOSE: To reduce in size bubbles generated by an underwater bubble generator. ;CONSTITUTION: The bubble diameter regulation type underwater bubble generator comprises a sealed water tank 5 having a water supply pump 13 and a drain pump 10, a pressure reducing pump 8 for reducing the pressure of the tank 5, a bubble discharging unit (rotary disc 1 and a micropore material 2 provided at the disc 1) for generating bubbles in the pressure-reduced tank 5, and a water tank 11 disposed out of the tank 5 to reduce in size the bubbles 4 generated in the tank 4 via the pump 10 in the atmosphere.;COPYRIGHT: (C)1997,JPO
