The water mist sprayed by the nozzles 208 can change the characteristics of particulate matter in the exhaust gas, making it easier to be captured by the filter cotton frame, thereby improving the efficiency of the filtration system and reducing the particulate matter content in the exhaust gas emission. The left end of the outer surface of the spray barrel 201 is fixedly connected with a first air inlet pipe 3, and the left end of the first air inlet pipe 3 is connected with a filter assembly 4. The filter assembly 4 includes a filter cartridge 401, the right side of the filter cartridge 401 is connected with the first air inlet pipe 3, and the left end of the filter cartridge 401 is fixedly connected with a second air inlet pipe 5.

[0027] Reference Figure 1 , Figure 2 and Figure 4As shown, a fan 7 is provided at the upper end of the support plate 1, and the fan 7 is fixedly installed on the right side of the spray barrel 201.

The corona discharger 902 generates a corona discharge area. The waste gas enters the corona discharge area. Under the action of high electric field strength, a corona discharge plasma reaction occurs. The free radicals and oxidants generated by these reactions can chemically react with organic pollutants and gaseous pollutants in the waste gas, oxidizing them into harmless substances or substances that are easy to handle, and finally discharged through the outlet pipe 10.
