The high-pressure water pump 13 is fixed on the top of the water tank 2.

[0033] In the specific implementation of the embodiment:

[0034] Before treating the exhaust gas, the water supplement pipe 10 is opened to start adding water into the treatment tower 1. When the water level exceeds the water inlet port 8 by about 25 cm, the high-pressure water pump 13 is opened to start spraying, and the molecular sieve is wetted. When the water level is about 60-65 cm, the water supplement is stopped, the chemical adding pipe 11 is opened to add treatment chemicals into the water body (the first addition needs to be over-added), and the addition is stopped after enough chemicals are added. After 10-20 minutes, the treatment chemicals and water are fully mixed in the spraying and falling circulation.

[0035] The exhaust gas treatment is started. The air valves 4 of the air outlet pipe 5 and the air inlet pipe 3 are opened, and the end negative pressure fan is started. Part of the exhaust gas (acid and alkali exhaust gas, nitrogen-containing exhaust gas, and fluorine-containing exhaust gas) generated in the workshop is absorbed and collected, and is sent into the treatment tower 1 through the air inlet pipe 3. After passing through the spiral flow guide 18, the exhaust gas is guided by the spiral flow guide 18 to form a cyclone, so that the gas in the treatment tower 1 is uniformly mixed, and the wind speed is reduced. The exhaust gas enters the high-efficiency reaction layer in the form of a cyclone, contacts the liquid remaining on the molecular sieve in the molecular sieve pile, and the gas passes through the high-efficiency reaction layer and contacts the chemical dilution liquid sprayed and fallen from above, so that the harmful components in the exhaust gas are reacted and dissolved in the liquid. The treated exhaust gas falls to the bottom of the treatment tower 1 (the molecular sieve layer and the spraying structure increase the contact effect of the exhaust gas and the treatment liquid, improve the exhaust gas treatment capacity, and the exhaust gas reacts with the treatment liquid flowing on the fan structure of the spiral flow guide 18 during the rising process), and is discharged from the treatment tower 1 through the air outlet pipe 5 and is sent into the chimney by the negative pressure fan for standard high-altitude emission.

[0036] During the treatment of the exhaust gas, the water level, PH, ORP, and conductivity of the water body in the treatment tower 1 are monitored, and the water is replaced and chemicals are added according to the parameters. When the water is replaced, the water level is not less than 20 cm.

In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
