Abstract:
A method of dissolving and mixing a gas and a liquid comprising the steps of:providing an injection portion for injecting a liquid in a horizontal direction at an upper part of a mixing container filled with a gas;providing a restrictor, which is a restricted channel, for maintaining a pressurized state in said mixing container downstream of said mixing container;injecting a liquid into the mixing container from the injection portion to cause a reaction or dissolution between the gas in said mixing container and the injected liquid in the pressurized state and to cause a liquid including the gas dissolved therein to flow from a lower part of said mixing container;stopping the supply of the liquid into said mixing container when the gas in said mixing container is reduced as a result of the dissolution of the gas into the liquid therein;supplying the gas into said mixing container; andalternately performing the injection of the liquid and the supply of the gas into said mixing container.
