The reaction component 2 is arranged on the main platform 1, the filtering component 3 is arranged on the main platform 1 and connected to the reaction component 2, the lifting component 4 is arranged below the main platform 1, and the moving component 5 is arranged around the bottom of the main platform 1.

[0022] like Figure 1-3 As shown, the reaction assembly 2 includes an air duct 6, a booster pump 7, an ammonia water tank 8, a baffle 9, an air duct 2 10 and a reaction barrel 11. The air duct 6 is arranged to pass through the reaction barrel 11, the booster pump 7 is arranged on the air duct 6, the ammonia water tank 8 is arranged in the reaction barrel 11, the baffle 9 is vertically arranged in the reaction barrel 11, and the air duct 2 10 is arranged to pass through the baffle 9.

[0023] like Figure 1-3 As shown, the baffles 9 and the air guide pipes 10 are arranged in two groups, and the ammonia water tanks 8 are arranged in three groups.

[0024] like Figure 1-3 As shown, the filter assembly 3 includes an exhaust pipe 12, a support frame 13, a filter barrel 14, a filter limiter 15 and a filter screen 16. The exhaust pipe 12 is arranged to pass through the other side of the reaction barrel 11, the support frame 13 is arranged on the main platform 1, the filter barrel 14 is arranged on the support frame 13 and is connected to the exhaust pipe 12, the filter limiter 15 is arranged on the inner wall of the filter barrel 14, and the filter screen 16 is arranged at the discharge position of the filter barrel 14.

[0025] like Figure 1-3 As shown, the lifting assembly 4 includes a base 17, a lifting motor 18, a threaded rod 19 and a sliding rod 20. The base 17 is arranged below the main platform 1, the lifting motor 18 is fixedly connected to the base 17, the threaded rod 19 is extended from the output shaft of the lifting motor 18 and passes through the main platform 1, and the sliding rod 20 is arranged on the base 17 and passes through the main platform 1.

[0027] During specific use, the sulfuric acid tail gas is pressurized by the booster pump 7 from the air duct 6 and enters the reaction barrel 11 to react with the ammonia water in the ammonia water tank 8. Because the ammonia water tank 8 is divided into several compartments by the baffle 9 and the air duct 10, the reaction time of the sulfuric acid tail gas and the ammonia water can be increased so that the sulfuric acid tail gas can fully react. Finally, it enters the filter assembly 3 through the discharge pipe 12, and can have a filtering effect after passing through the filter limit 15 and the filter screen 16.
