[0033] The working principle of this utility model:

[0034] When in use, after fixing the equipment, the exhaust gas pipeline to be treated is connected to the cooling tank 201. When the exhaust gas enters the interior of the cooling tank 201, the temperature of the exhaust gas is cooled by the internal fins 202, and the exhaust gas is transported to the interior of the box body 1 through the delivery pipe, and then the water pump 303 is started to reach the first water pipe 302 to extract the water inside the water tank 301, and then the water is transported to the interior of the water pump 303 through the first water pipe 302, and then transported to the interior of the second water pipe 304 through the water pump 303, and then transported to the interior of the spray plate 305 through the second water pipe 304, and then transported to the interior of the spray plate 305 through the spray plate 305.

The exhaust gas after filtration enters the inside of the L-shaped tube 101, and is detected by the air detector 102 on the L-shaped tube 101 to see if it meets the emission standard. Then, by starting the fan 103, when the emission standard is met, the fan 103 is used to transport it to the inside of the first connecting pipe 104, and then by starting the second solenoid valve 107, the exhaust gas is transported to the inside of the exhaust hole 108 for discharge.
