METHOD FOR PREPARING GAS-DISSOLVED SOLUTION

摘要

PURPOSE: A method for preparing gas-dissolved solution by dissolving gas in water in a pressurized spraying manner is provided by which prepared gas-dissolved solutions are employed in a wide variety of industries according to the kind of dissolved gases. CONSTITUTION: The method comprises steps of: (i) supplying a water tower with water for producing gas-dissolved solution and supplying gas through a gas generator(10); (ii) mixing the gas supplied from the gas generator(19) with the water inhaled from the water tower; and (iii) exhausting a pressurization tank(10) of the water mixed with the gas. In the step (ii), an ejector(7), which makes the speed of a running fluid to mix the gas and the water, a static mixer(8), which divides and blends the mixed solution and the residual gas, and a mixing melting machine(9), which has many nozzles to mix the gas and the water, are used.
