Iron oxide desulfurizer waste recycling method

The invention discloses an iron oxide desulfurizer waste recycling method. The method comprises the following steps that 1, a waste desulfurizer is filtered to remove impurities in the waste desulfurizer; 2, the filtered waste desulfurizer is crushed by using a crusher; 3, the crushed waste desulfurizing agent is conveyed to a placing site through a trolley to be aired, wherein the placing site needs to be kept flat and clean, and the waste desulfurizing agent needs to be flatly spread and placed in blocks when placed; 4, the drying mode is natural air drying, the drying time is 2-3 days, and turning treatment is conducted every 4-6 hours; 5, after air drying is completed, packaging treatment is conducted through a packaging bag; and 6, the recycled and treated waste desulfurizer is mixed in raw material pyrite to produce sulfuric acid. Compared with the prior art, the method has the advantages that the waste desulfurizer is treated and recycled, so that the pollution to the environment is reduced, and meanwh
