When the rotating column 9 rotates, the rotating disk 11 is driven to rotate. When the rotating disk 11 rotates, the swing frame 13 is driven to drive the spray pipe 3 to rotate. When the spray pipe 3 rotates, the exhaust gas is rotated to spread ammonia water. By allowing the spray pipe 3 to be driven by the swing frame 13 and the nozzle on the spray pipe 3 is driven to evenly spread ammonia water on the exhaust gas in the exhaust tower 1 when rotating, the contact area between ammonia and sulfur dioxide can be increased, thereby increasing the desulfurization efficiency and improving the desulfurization effect.

[0042] The exhaust gas after desulfurization will be filtered by the filter box 15 to filter the dust inside. When the rotating column 9 rotates, it will also drive the rotating bar 16. The rotating bar 16 will drive the driving bar 17, thereby driving the long rod 18, and the long rod 18 drives the cleaning plate 19, and the cleaning plate 19 cleans the dust at the bottom end of the filter box 15. By allowing the cleaning plate 19 to clean the dust at the bottom end of the filter box 15 driven by the long rod 18, it can ensure that the pores of the filter box 15 are always unblocked, thereby ensuring that the exhaust gas can be smoothly discharged from the exhaust tower 1, and maintaining the stable operation of the desulfurization device.
