Although the liquid is agitated by (7), the liquid flow (7) is not formed near the deepest part of the bottom (5) of the liquid storage tank (1), and the agitation becomes insufficient. That is, in general, when a gas is discharged into a liquid, whether the amount of gas discharged into the liquid is large or small is determined by the flow loss in the pipe and the liquid pressure at the bubble discharge hole. Then, the amount of gas released into the liquid is large, and conversely, the amount of gas released into the liquid is small when the liquid depth is deep. This tendency is the same in the liquid storage tank as well, and the amount of gas released into the liquid decreases as the distance from the gas supply pipe (2) increases, as shown in FIG. In about half the area,
No gas is released. Therefore, the liquid flow (circulation flow in the vertical direction) (7) near the deepest part of the bottom (5) of the liquid storage tank (1).
Stirring is inadequate due to the lack of formation.
