GAS DISSOLUTION APPARATUS

摘要

An apparatus which comprises: gas-dissolving devices (8 and 9) in which a gas/liquid mixture is continuously introduced while causing a turbulent flow in the gas/liquid mixture to thereby heighten the dissolution of the gas in the mixture and which send the resultant solution of the gas; gas solution ejection orifices connected to the gas-dissolving devices; and a pressure tank (11) in which the gas solution injected into the space within the tank from the gas solution ejection orifices is stored so that the solution can be supplied to the outside of the tank. This apparatus can heighten the efficiency of gas absorption to dissolve a gas toa saturation value in a short time (e.g., by a one-through operation), and enables this state to be maintained for long. This apparatus can have a reduced size as a whole and be economically provided.
