PROBLEM TO BE SOLVED: To provide a gas dissolving apparatus in which an area of an interface of liquid and gas stored in a roughly cylindrical body is increased and flow out of liquid with large bubbles mixed therein from the cylindrical body is prevented by deepening the depth of the stored liquid.SOLUTION: This gas dissolving apparatus 1 stores gas and liquid in the cylindrical body 2, and dissolves gas into liquid by jetting the gas-liquid mixed fluid in which gas and liquid are mixed in the cylindrical body 2. The cylindrical body 2 is disposed with its central axis a tilted state in relation to the horizontal direction b, the interface 40 of the gas and liquid stored in the cylindrical body 2 is located at the intermediate part of a roughly cylindrical side wall part 21 of the cylindrical body 2, and an upper side above the interface 40 in the cylindrical body 2 and a lower side are used as a gas storing part 41 and a liquid storing part 42, respectively. A jetting port 31 is provided at the same level as the interface 40, or at a slightly lower level in the cylindrical body 2, for jetting the gas-liquid mixed fluid into the gas storing part 41 in the cylindrical body 2, and a flow out port 32 is provided near a lower end part of the cylindrical body 2 for running out the liquid in the cylindrical body 2.COPYRIGHT: (C)2008,JPO&INPIT【課題】略円筒状をした筒状体の内部に貯留される液体と気体との界面の面積を大きくすると共に、貯留される液体の深さを深くして大きな気泡が混合された状態で筒状体から流出することのない気体溶解装置を提供する。【解決手段】筒状体2内に気体と液体とを貯留すると共に、筒状体2内に気体と液体とが混合した気液混合流体を噴射して気体を液体に溶解させる気体溶解装置1である。筒状体2をその中心軸イが水平方向ロに対して傾斜するように配置し、筒状体2の略円筒状をした側壁部21の中間部に内部に貯留される気体と液体の界面40を位置させ、筒状体2内の界面40より上側、下側の部分を夫々気体貯留部41、液体貯留部42とし、筒状体2の界面40と同レベル又は若干下のレベルに気液混合流体を筒状体2内の気体貯留部42に噴射する噴射口31を設け、筒状体2の下端部近傍に筒状体2内の液体を流出させる流出口32を設けた。【選択図】図1
