[0061] The filtered tail gas enters the treatment hopper 21, start the spiral dust collector 22, perform dust removal operations through the spiral dust collector 22. The treated tail gas enters the buffer area 35, then enters the discharge main pipe 34 along the smoke pipe 32, and finally is discharged through the discharge main pipe 34;

[0062] Cold water is added into the heat exchange cylinder 31 through the cold water inlet pipe 311, and the tail gas enters the flue gas pipe 32 to heat the cold water inside the heat exchange cylinder 31.
