[0025] A threaded rod 8 is rotatably installed between the two sides of the inner wall of the desulfurization box 1, a linkage mechanism 7 is arranged between the abutment rod 6 and the threaded rod 8, and a cleaning mechanism 9 for cleaning the spray panel 3 is installed on the outside of the threaded rod 8. The cleaning mechanism 9 cleans the spray panel 3 to prevent the spray panel 3 from being blocked by dust particles in the air, thereby ensuring the uniform spraying of the desulfurizer by the spray panel 3, thereby ensuring the desulfurization effect of the equipment.

[0026] Specifically, the linkage mechanism 7 includes a synchronous wheel 71, which is fixedly sleeved on the outside of the rotating shaft 5. A connecting rod 72 is rotatably installed on the inner wall of the desulfurization box 1. A synchronous wheel 2 73 is fixedly sleeved on one end of the connecting rod 72. A synchronous belt 74 is installed on the outside of the synchronous wheel 2 73 and the synchronous wheel 1 71. When the driving motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 can drive the synchronous wheel 1 71 to rotate. The rotation of the synchronous wheel 1 71 can drive the synchronous wheel 2 73 to rotate through the synchronous belt 74. The rotation of the synchronous wheel 2 73 can drive the connecting rod 72 to rotate.

[0027] More specifically, one end of the connecting rod 72 close to the threaded rod 8 is fixedly connected to a bevel gear 1 75, and one end of the threaded rod 8 is fixedly sleeved with a bevel gear 2 76.
