<P>PROBLEM TO BE SOLVED: To dissolve an appropriate amount of air into water using a pressurized container. <P>SOLUTION: A tank 31 for pressurizing and introducing water or air-containing water is provided, notches K are formed on the outer circumferential side of a partition plate 34 vertically partitioning the tank 31, water is made to flow from an upper part to a lower part of the partition plate 34, and the water and air undissolved in the water are separately stored. The notches K are formed corresponding to the flow rate of the water to be introduced to the tank 31, and a jet flow stream flow-down means for dropping the water or the air-containing water to the water surface of the stored water as a stream in a jet flow state and pushing it under the water surface is formed. The stream pushed in by the jet flow stream flow-down means is stored in a pressurized state while being agitated lowering a flow speed in the water, a hydraulic jump phenomenon by discontinuous change from the jet flow to regular flow is generated when the flow speed is lowered and agitation is performed, and the undissolved air inside the tank 31 or the air introduced together with the water inside the tank 31 is dissolved in the stored water by vortex motion formed by kinetic energy discharged when it is generated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
