METHOD, DEVICE, AND SYSTEM FOR CONTROLLING DISSOLVED AMOUNT OF GAS

摘要

A device for controlling dissolved amount of gas, comprising a pressure reducing part capable of bringing the inside of a tank into a reduced pressure space by connecting a hole provided at the upper part of the closed tank to a vacuum pump through a pipe, an injection supply part injecting pressurized treated fluid from the inside upper part of the tank with a nozzle capable of covering the large part of the reduced pressure space, a liquid foam generating part receiving the injected treated fluid by a container at the opening center part thereof and generating a large amount of air bubbles at the bottom part thereof and changing the air bubbles into liquid bubbles, a recovery pump part allowing the liquid bubbles overflowing from the upper end of the container to fall to a lower part, temporarily storing the liquid bubbles as deaerated treated fluid, and recovering the treated fluid, and a tank water level sensor part transmitting information for maintaining the water level of the treated fluid stored in the tank to a pump and a valve.
