Further, there is a problem in that the energy loss of the liquid in the gas-liquid mixing cylinder becomes large, and it is not possible to maintain a good agitation and mixing effect of the gas-liquid.

の液体が吸引されると流動の容積が増大して更に拡がシ
角度が増大する（約１０°）。A liquid is injected from a liquid injection pipe into a gas-liquid mixing cylinder, and gas is sucked into or blown into the liquid from a gas blowing pipe at the front end of the gas-liquid mixing cylinder. The liquid injected from the liquid injection tube collides with the gas from the gas blowing tube, atomizes it, and at the same time sucks the surrounding liquid from the front end of the gas-liquid mixing cylinder. The liquid thus injected and drawn into the gas-liquid mixing cylinder is mixed with the atomized gas passing through the gas-liquid mixing cylinder, and then discharged from the rear end of the gas-liquid mixing cylinder. The liquid injected from the liquid injection tube spreads at a certain angle (approximately 2 degrees) inside the gas-liquid mixing cylinder, but when the gas is blown in and the surrounding liquid is sucked, the volume of the flow increases and it spreads further. The angle increases (approximately 10°).

液混合が行われる。The liquid-gas mixture whose expansion angle has increased in this way is subjected to large flow resistance when it collides with the inner wall of the gas-liquid mixing cylinder. In order to reduce the flow resistance experienced by such a liquid-vapor mixture, it is desirable that the cross-sectional area of the gas-liquid mixing tube be at least 10 times the cross-sectional area of the injection hole of the liquid injection tube. If the length is at least twice the tlf diameter of the gas-liquid mixing cylinder, sufficient gas-liquid mixing will occur while the liquid-gas mixture passes through the gas-liquid mixing cylinder.
したがって本発明においては液体を気液混合装置に送シ
込む際のエネルギー効率が高くｈシ、かつ気液撹拌混合
効果も高くなる。Therefore, in the present invention, the energy efficiency when feeding the liquid to the gas-liquid mixing device is high, and the gas-liquid stirring and mixing effect is also high.
