Desulfurization ash hopper applied to boiler

The utility model discloses a desulfurization ash hopper applied to a boiler, and relates to the technical field of boiler desulfurization. An exhaust pipe is installed at the air outlet end of the boiler body, an installation frame is installed on one side of the boiler body, a treatment hopper is installed on the installation frame, limestone slurry is contained in the treatment hopper, an air inlet pipe penetrates through and is welded to one side of the treatment hopper, and the air inlet pipe is of an L-shaped structure. According to the flue gas treatment device, sulfur dioxide in flue gas is absorbed by limestone slurry to generate calcium sulfite hemihydrate or oxidized into gypsum, and the treated flue gas enters the first pipeline and the second pipeline and then is in contact with the limestone slurry, so that the effect of repeatedly treating the flue gas can be achieved; the sulfur dioxide in the flue gas is circularly treated, so that the sulfur content in the flue gas after the boiler body mate
