The utility model discloses a desulphurization unit is absorbed in multistage circulation of active ore pulp, the device mainly includes the one -level absorption tower, secondary absorption tower, active ore pulp storage tank and absorption liquid storage tank, its utilization contains a quantitative mgO, caO, al2O3, basic oxide's such as fe2O3 active ore pulp is as the desulfurizer, traditional desulfurizer has been replaced, tentatively absorb the back to the sulfur dioxide that the low concentration is smelted in the flue gas through the active ore pulp in the one -level absorption tower, active ore pulp through among the secondary absorption tower further absorbs the sulfur dioxide in the flue gas, it smelts the two -stage circulation of flue gas and absorbs to have realized the low concentration, can guarantee efficient desulfurization effect, and simultaneously, through the chain valve of first liquid level, chain valve of second liquid level and the chain valve of pH value make the active ore pulp to
