description The absorption tower comprises an absorption tower body which is divided into an upper layer and a lower layer, the lower layer comprises filler and a liquid distribution plate, organic amine liquid evenly flows into the filler through the liquid distribution plate and makes full contact with sulfuric acid tail gas, SO2 in the sulfuric acid tail gas is dissolved in the organic amine liquid, and the sulfur-containing tail gas is discharged through the liquid distribution plate. SO2 in the sulfuric acid tail gas is reduced; the upper layer comprises a liquid collecting plate, a rotational flow ejector, a washing spraying layer, a demister washing spraying layer, a demister and a control turning plate, alkaline washing water passes through the washing spraying layer and the rotational flow ejector, is gathered on the liquid collecting plate and flows back to the washing tank, on one hand, smoke dust in the sulfuric acid tail gas can be washed away, and on the other hand, SO2 in the sulfuric acid tail gas can be
