Embodiment 1
[0034] A semi-dry flue gas desulfurization ash modification treatment method, using MnO 2 The flue gas desulfurization ash is modified together with water and oxidants, so that the flue gas desulfurization ash is continuously oxidized during the modification process, wherein the calcium oxide in the flue gas desulfurization ash is converted into calcium hydroxide, and calcium sulfite is converted into sulfuric acid Calcium, so as to obtain modified desulfurization ash. The whole process flow of the modified desulfurization ash is:
[0035] 1. Weigh the desulfurization ash, and crush the desulfurization ash into powder, generally 200-300 mesh;
[0036] 2. Put the desulfurization ash into a closed container;
[0037] 3. Select MnO according to the weight of desulfurization ash 2, and MnO 2 Crushed into powder, the particle size is the same as that of desulfurization ash;
[0038] 4. MnO 2 The powder and water are mixed according to the weight ratio of 1:45, and turned into...
