GAS-LIQUID DISSOLVING TANK IN APPARATUS FOR GENERATING MICROBUBBLE

摘要

PROBLEM TO BE SOLVED: To provide a gas-liquid dissolving tank which can be made inexpensive while being miniaturized and in which the dissolution efficiency of a gas in a liquid can be improved even under low pressure. SOLUTION: The gas-liquid dissolving tank 8 is provided with: an airtight tank body 11; a suction port 14 arranged on the outside of the tank body 11; an injection nozzle 16 which is arranged in the tank body 11 and has a jet orifice 16a directed upward; a discharge port 19 which is arranged in the position lower than the liquid level 17 of the tank body 11 and used for discharging the liquid in the tank body 11 to the outside; and a collision part 20 which is arranged to be opposed to the jet orifice 16a and is the undersurface of the upper ceiling part 11b on the inside of the tank body 11. A gas-liquid mixture is jetted from the jet orifice 16a and made to collide against the collision part 20 to obtain a gas-dissolved liquid. The gas-liquid dissolving tank 8 is used in an apparatus A for generating microbubbles. COPYRIGHT: (C)2009,JPO&INPIT
