<p>PURPOSE:To make minute the foams of a gas blown into liquid without generating cavitation when a large volume of gas is blown in by forming a gas exhaust outlet vertically and downwardly on the discharge side of a side face type agitation blade set in liquid rotatably. CONSTITUTION:A propeller-shaped side face type agitation blade 8 for generating and agitating discharge flow out of absorbing solution in a liquid storage tank 4 is set rotatably in the vicinity of side wall in the absorbing solution in the tank 4 of an absorption tower 1. An air blowing pipe 12 is connected with the liquid storage tank 4, and the air blowing pipe 12 is extended to the front of the agitation blade 8 in the absorbing solution, and its front section is of a straight pipe shape vertically and downwardly on an extension line of a rotating shaft of the agitation blade 8, and an air plenum 13 for blowing air vertically and downwardly is formed on an end section. As the air is blown into the discharge side of the agitation blade 8 as above, foams are made minute without generating cavitations when a large volume of gas is blown in.</p> |
