Continuous dry/semi-dry desulfurized fly ash stabilizing treatment system and method

The invention discloses a continuous dry/semi-dry desulfurized fly ash stabilizing treatment system. The system comprises a desulfurization ash pulping tank, an alkali liquor tank, an acidification tank, a first-stage aeration tower and a second-stage aeration tower which are arranged in sequence. The invention further discloses a continuous dry method/semi-dry method desulfurized fly ash stabilizing treatment method. The method comprises a raw material analysis step; a slurry preparation step; a slurry rotational flow step; an raw material acidifying step; a forced oxidation step; a SO2 reabsorption step; a partial slurry discharging step; and a product dehydration step and a waste liquid circulation and Mg recovery step. The oxidation rate of the whole modification process is remarkablyincreased, and the whole stabilization treatment process is environmentally friendly and clean. Meanwhile, the system and the method have the advantages of being simple in structure, free of moving parts, reliable in work, fl
