<p>PROBLEM TO BE SOLVED: To provide a gas/liquid mixing dissolving device capable of enhancing the dissolution efficiency of the gas and reducing cost and noise. SOLUTION: A cylindrical body 23 is inserted into the liquid of a liquid tank 21 and the liquid and the gas are suctioned from an upper part of this cylindrical body 23. The liquid and the gas in the cylindrical body 23 are suctioned to a lower part of the cylindrical body 23 while they are stirred and mixed and a pump 24 for discharging them to the periphery is provided on the lower part of the cylindrical body 23. The dissolution efficiency of gas is enhanced by continuously carrying out gas dissolving treatments at three stages, i.e., the dissolution of the gas by a gas/liquid stirring mixing action in the cylindrical body 23 generated by the suction force of the pump; the dissolution of the gas by a gas/liquid stirring mixing action in the pump 24; and the dissolution of the gas when bubbles 59 discharged from the pump 24 into the liquid are floated up in the liquid.</p> |
