This utility model provides a wet desulfurization system for aluminum electrolysis flue gas, relating to the technical field of wet system technology. It includes a slurry tank and a support frame. The support frame is positioned above the slurry tank, and a drive assembly is located at the middle of the support frame. The slurry tank contains stirring blades, and the drive assembly drives the stirring blades to rise, fall, and rotate. A limestone powder hopper is located on one side of the support frame. This utility model arranges a disc-shaped jet assembly and stirring blades in the slurry tank. Before the slurry enters the desulfurization tower, it undergoes pre-treatment for oxidation and crystallization. The disc-shaped jet assembly introduces oxygen in advance, creating an oxidizing atmosphere in the slurry. When the slurry subsequently enters the desulfurization tower and reacts with SO2 to generate CaSO3, it can be oxidized to CaSO4 more quickly because O2 is already sufficient, eliminating the need to wait for oxidation within the tower. The solubility of CaSO4 is much lower than that of CaSO3, making it easier to crystallize and precipitate. Crystallization promotes the forward reaction, reducing unreacted CaCO3 residue in the slurry.
