PURPOSE:To get good contact of gas and liquid, by submerging a cylindrical body rotating at high speed in a liquid phase, introducing gas into the cylinder from the upper opening, and making the liquid stream flow into the center of the cylinder in accompany with the gas. CONSTITUTION:When a shaft 8 is rotated at high speed, the liquid of a liquid phase 5 flows from the opening 4 of a porous cylindrical matter 1 to the center, collides with the inner surface of the cylinder wall 2 by a centrifugal force, passes through fine pores of the cylinder wall 2 being divided into fine streaks, and flows again to the opening 4. On the other hand, as a gas is introduced from a gas blowing pipe 10 into the cylinder 1, the gas is accompanied with the liquid circulating along curved lines as shown by arrows, passes through the fine pores of the cylinder 2, and contacts with the liquid effectively during this time. The gas is spouted from the outer surface of the cylinder wall 2 to the liquid, and becomes fine bubbles. |
