The drying plate 10 prevents the solid particles and water vapor contained in the exhaust gas from affecting the adsorption function of the activated carbon.

[0026] The spray mechanism 1 includes a spray plate 4 installed in the spray purification box 1. The spray plate 4 is connected to the bottom of the spray purification box 1 through a spray pipe 5. The spray pipe 5 is equipped with a pump 6 that pumps water to the spray plate 4. The pump 6 pumps water from the bottom of the spray purification box 1 to the top of the spray plate 4, where it is sprayed for recycling.

[0027] The spray purification box 1 is equipped with a rotating motor 16. The output shaft of the rotating motor 16 is connected to the spray plate 4. The spray pipe 5 is connected to the spray plate 4 via a rotating joint 17. The rotating motor 16 drives the spray plate 4 to rotate, improving the spraying effect. The spray pipe 5 supplies water to the spray plate 4 via a rotating joint 17.
