The spray pipe 300 comprises a base 110, a tower body 120 and an exhaust pipe 130 which are coaxially flange-assembled from bottom to top. A drain pipe 140 and an exhaust gas inlet pipe 150 are respectively provided at the bottom of the left and right sides of the tower body 120. The height of the drain pipe 140 is lower than the height of the exhaust gas inlet pipe 150. The filter medium 200 comprises a mesh box 210, a cover plate 220, a drive rod 230 and a stirring paddle 240. The cover plate 220 is coaxially covered and installed at the opening at the top of the mesh box 210. The top end of the drive rod 230 coaxially passes through the bottom of the mesh box 210 and extends into the mesh box 210. The stirring paddle 240 is coaxially built into the mesh box 210 and fixedly connected to the top end of the drive rod 230.

[0019] Based on the arrangement of the above structure, specifically, during the working process, the flue gas enters the desulfurization tower 100 through the exhaust gas inlet pipe 150, and the flue gas moves upward to interact with the alkaline solution sprayed from the spray pipe 300, thereby realizing the desulfurization treatment of the flue gas. The flue gas continues to pass through the filter medium 200, completing further filtration of the flue gas, and is finally output from the exhaust pipe 130. In the packing carrier composed of the mesh box 210 and the cover plate 220, under the rotation of the driving rod 230, the stirring paddle 240 rotates in the packing carrier, and the packing contained in the packing carrier is fully stirred, so that the packing in the packing carrier is The material can interact evenly and fully with the passing flue gas. The environmentally friendly desulfurization device improves the traditional static filter medium and is provided with a stirring paddle 240 in the filler carrier composed of a mesh box 210 and a cover plate 220. During the desulfurization process, the stirring paddle 240 can be driven by the rotation of the driving rod 230 to stir the filler filled in the mesh box 210 to adjust the level of the filler in the carrier.
