The first spray pipe 24, the second spray pipe 25 and the third spray pipe 26 are annular pipes and are equidistantly arranged, so that the treatment liquid can form a more uniform spray coverage area in the tower, and more comprehensively contacts with the tail gas, thereby effectively removing harmful substances in the tail gas and improving the efficiency and quality of the tail gas treatment.
