Title:
GAS DISSOLVING DEVICE
Document Type and Number:
Japanese Patent JP3758471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas dissolving device capable of increasing a dissolved oxygen quantity much more.
SOLUTION: This gas dissolving device consists of a pump for feeding water into an erected cylindrical tank, a gas feed means for feeding pressurized gas into a space in the tank, a water level maintaining means for maintaining water in the tank at a specified water level, and a pressure adjusting valve for adjusting the pressure of water to a specified pressure at a time of discharging the water to the outside of the tank. When the water is fed into the tank, it is branched to at least two directions and one is dropped from the above mentioned space and the other is fed at the position lower than the water level of the above specified water level and also from the tangent direction of the inner periphery of the tank.
