The filter assembly is a flue gas filter cylinder, which is used for filtering large particles in the flue gas entering the desulfurization tower. The dredging assembly is arranged in the flue gas filter cylinder and is used for dredging the filter holes arranged on the side wall of the flue gas filter cylinder. A servo motor drives a rotating rod to rotate and thus drives multiple extruding blocks to extrude the pressure receiving inclined blocks on the moving plate. At this time, the pressure receiving inclined blocks are extruded by the extruding blocks outward, so as to drive the moving plate to move and ensure that the dredging rods above the moving plate are inserted into the filter holes during the movement of the moving plate, thereby avoiding the problem of blockage of the filter mechanism.
