<p><P>PROBLEM TO BE SOLVED: To provide a gas dissolving device which effectively dissolves active gas such as oxygen into liquid without loss, and to provide a water treating device which supplies oxygen to plants and animals in an oxygen-deficient region in a deep dam or in the sea, and cleans up an environment by restoring sludge-mixed water left on the bottom of the water. <P>SOLUTION: The gas dissolving device 1 is for dissolving the gas in a gas- mixed solution into the liquid. The gas-mixed solution is injected from a cylindrical lower side wall of the device via an ejector nozzle and the pressure in the gas dissolving device is reduced, and the gas is expanded and converted into water bubbles by being reduced in pressure, and then instantly dissolved into the water bubbles and surfaces thereof by the pressurized gas in the water bubbles. The dissolved solution is discharged to a discharge part through a cylindrical part 3 and a cylindrical water passage 4, and the gas is made to separate to the uppermost part. The gas is repeatedly self-taken in the ejector nozzle to make a large amount of water bubbles be generated and the water bubbles are broken by the injection force and revolution flow of the ejector nozzle, whereby the gas is dissolved continuously. <P>COPYRIGHT: (C)2004,JPO</p> |
