The cache collection box 13 is connected to a No. 1 water pump 14 through a water pipe, and the No. 1 water pump 14 is connected to a spray tower 3 through a water pipe.

[0022] During waste gas treatment, the waste gas enters the spray tower 3 from the air inlet pipe 1, and the No. 4 water pump 17 draws water from the circulating water tank 10 and sends it to the spray tower 3. The spray tower 3 sprays and cleans the internal waste gas. After being sprayed, the waste gas enters the waste gas adsorption tower 5 from the No. 1 air pipe 4. The harmful substances in the waste gas are adsorbed and treated by the waste gas adsorption tower 5. The treated waste gas enters the fan 7 from the No. 2 air pipe 6 and is sent to the exhaust chimney 9 by the fan 7 for discharge.
