27. In this embodiment, the gas enters the heating air cylinder 307 through the air inlet cylinder 301, and the metal protective net 302 protects the internal device to prevent debris from entering and affecting the rotation of the regulating fan blade 305.

28. Specifically, one end of the connecting shaft 303 is provided with a connecting ring 304, the inner wall of the connecting ring 304 is fixedly connected with the outer wall of the connecting shaft 303, the outer wall of the connecting ring 304 is fixedly installed with a flow regulating fan 305, and the outer wall of the connecting shaft 303 is movable A fixing frame 306 is installed.

29. In this embodiment, the connecting shaft 303 drives the connecting ring 304 to rotate, and the connecting ring 304 drives the flow regulating fan 305 to rotate to adjust and buffer the incoming airflow.

30. Specifically, one end of the air inlet cylinder 301 is fixedly installed with a heating air cylinder 307, and the bottom of the heating air cylinder 307 is fixedly installed with a water inlet pipe 308. One end of the water inlet pipe 308 is provided with a heat exchange coil 309. One end is fixedly connected with one end of the water inlet pipe 308, and the other end of the heat exchange coil 309 is fixedly connected with a drain pipe 310.

31. In this embodiment, the wastewater enters the heat exchange coil 309 through the water inlet pipe 308, and the heat exchange coil 309 heats the airflow in the heating air cylinder 307, and is discharged through the drain pipe 310.

32. Specifically, the inner wall of the heating air cylinder 307 is fixedly installed with an insulation layer 311, the heating air cylinder 307 is provided with a dust-proof net 312, and the outer wall of the dust-proof net 312 is fixedly connected to the inner wall of the heating air cylinder 307, and the heating air cylinder A sealing ring 313 is fixedly installed on the outer wall of 307.
