To explain the operation of the device of the present invention as described above, water in the closed tank 1 is taken out by the water draw-out pipe 11, and this is made into high-pressure water by the high-pressure pump 13 and is jetted into the return pipe 12 from the nozzle 18 of the jet pump 14. By this,
Gas is sucked from one end of the return pipe 12 or from the atmosphere introduction pipe 16, and is introduced into the closed tank 1 together with high-pressure water.

このため戻し管12の一端側の減圧タンク内は負圧とな

In particular, the configuration in which the nozzle 18 of the jet pump 13 is exposed to the protective cylinder 17 and the atmospheric air introduction pipe 16 is connected to the protective cylinder 17 eliminates the negative pressure formed around the nozzle injection port and inhibits the momentum of the jet stream. Instead, the suction force from the other end of the return pipe is increased and the sucked atmospheric air is forced into the sealed tank.
