PURPOSE:To obtain the gas-liquid mixing apparatus having high power efficiency and a simple structure, by a method wherein a speed accerelating pipe nozzle is connected to the leading end part of a liquid supply pipe and a cover pipe is arranged to the outer peripheral part of said speed accerelating pipe nozzle. CONSTITUTION:A liquid sucking pipe 5 is drawn out from a liquid tank main body 2 and a pump 6 and a liquid supply pipe 10 are connected to said liquid sucking pipe 5 to guide the same above the tank 2 and a speed accerelating pipe nozzle 12 of which the diameter is gradually reduced toward a liquid level is further connected to the leading end of said liquid supply pipe 10. In addition, a cover pipe 15 of which the lower end is opened is arranged to the outer periphery of said nozzle 12 so as to leave a constant space therebetween without contacting with an injected liquid column 13. By this structure, self-sucking action similar to an ejector is effectively carried out in the space above the liquid level by the injected liquid column and a liquid is mixed and aerated with a gas by a simple apparatus having a high power efficiency. |
