GAS-LIQUID DISSOLUTION TANK

To provide a gas-liquid dissolution tank that is able to improve the dissolution ratio of liquid to gas, able to shorten a dissolution time, and able to be miniaturized.SOLUTION: A gas-liquid dissolution tank comprises: a tank body 2 having an inlet 2a and an outlet 2b for a gas-liquid mixture; and stirring means 3 disposed in the tank body and configured to stir a gas-liquid mixture that has flowed from the inlet. In the gas-liquid dissolution tank, the stirring means has a bottomed cylindrical form having an opening 3a and a bottom portion 3b. The opening is disposed opposite the inlet of the tank body with a predetermined interval between them. The gas-liquid mixture that has flowed from the inlet is stirred by being collided with the bottom portion of the stirring means.SELECTED DRAWING: Figure 1 【課題】液体と気体の溶解比率を高め、溶解時間が短縮でき、小型化が可能な気液溶解タンクを提供する。【解決手段】気液混合体の流入口２ａおよび流出口２ｂを有するタンク本体２と、タンク本体の内部に配置され、流入口から流入した気液混合体を撹拌させる撹拌手段３とを備える気液溶解タンクにおいて、撹拌手段は、開口部３ａおよび底部３ｂを有する有底筒状を成し、その開口部をタンク本体の流入口に所定の間隔を設けて対向させるように配置することにより、流入口から流入した気液混合体を当該撹拌手段の底部に衝突させて撹拌させるように構成した気液溶解タンクによる。【選択図】図１
