The cooling tower 1 is fixedly connected, the lower part of the cooling tower 1 is connected to the exhaust gas feed pipe 103, the upper part is connected to the exhaust gas discharge pipe 104, the other end of the exhaust gas discharge pipe 104 is connected to the spray humidification device 3, the spray humidification device 3 is connected to the condenser 4 through the discharge pipe 301, the condenser 4 is connected to the electrostatic purification device 5, the electrostatic purification device 5 is connected to the deodorization device 6, the deodorization device 6 is connected to the high-voltage electrostatic centralized purification box 7, and the high-voltage electrostatic centralized purification box 7 is connected to the venting chimney 8.

[0024] Furthermore, the water-cooled plate 201 is disc-shaped and has a refrigerant inside.

Each of the heat sinks 202 is provided with a plurality of ventilation grooves 203, and the cooling tower is connected to a pressure valve 204.

[0025] Furthermore, the spray humidification device 3 comprises a spray tank 31 , in which a water inlet pipe 32 is arranged, and the water inlet pipe 32 is connected to an annular water pipe 33 , on which a plurality of spray heads 34 are arranged in a circular array.

[0026] Furthermore, the electrostatic purification device 5 includes a shell 51, in which a filter plate 52 and a high-voltage electrostatic group 53 are sequentially arranged, and a ash hopper 54 is arranged at the bottom of the shell 51.

[0027] Furthermore, the deodorizing device 6 includes a box body 61 , in which a plurality of activated carbon adsorption chambers 62 are arranged, and two adjacent activated carbon adsorption chambers 62 are separated by a metal mesh 63 , in which activated carbon adsorption blocks 64 are arranged, and a cover plate 65 is arranged on the top of the box body 61 .
