<p><P>PROBLEM TO BE SOLVED: To provide a gas-liquid contact apparatus capable of efficient gas-liquid mixing agitation during an aeration in a large absorption liquid reservoir tank. <P>SOLUTION: The gas-liquid contact apparatus 1 has an aeration tank 10, a gas-liquid mixing mechanism 32, which keeps nozzle the tip penetrating the side wall of the aeration tank 10, and an agitator 31. The gas-liquid mixing mechanism 32 has liquid supply piping which forms a narrow-passage portion within the piping and has an opening for connection of the piping in the downstream of the narrow-passage portion and gas supply piping which is inserted into the opening of the liquid supply piping. When a liquid is allowed to flow into the liquid supply piping, a negative pressure is produced in the area of the opening in the downstream of the narrow-passage portion, and a gas is sucked from the opening and dispersed into the liquid. The agitator 31 arranged at a position above the gas-liquid mixing mechanism 32 so that the agitating surface 36 may be perpendicular to the streamline of the jet supplied by the gas-liquid mixing mechanism 32. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
