[0032] After the flue gas generated by production enters the processing chamber 14 through the air outlet 15, it is cooled by the condenser 12. The cold air generated by the condenser 12 enters the processing chamber 14 through the air pipe 13. The water pump 7 transports the water in the water tank 6 to the spray head 10 through the water pipe 9, and the water is sprayed out through the spray head 10, thereby further reducing the particle concentration and the flue gas temperature.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A second connecting square ring 4 is fixedly connected to the bottom end of the flue gas duct 2, a first connecting square ring 3 is arranged at the bottom of the second connecting square ring 4, the first connecting square ring 3 and the second connecting square ring 4 are connected by bolts 5, a smoke exhaust pipe 1 is fixedly connected to the bottom of the first connecting square ring 3, a fixing frame 16 is arranged inside the flue gas duct 2, and a filter element 17 is arranged inside the fixing frame 16.

[0034] The smoke exhaust pipe 1 is connected to the smoke duct 2 via two sets of square rings, and the two sets of square rings are connected via bolts 5 .

[0035] Reference Figure 2 and Figure 3 A handle 18 is provided on the top of the fixed frame 16, and a fixed threaded hole 22 is opened on the top of the fixed frame 16. A rotating rod 19 is fixedly connected to the top of the flue gas duct 2. A turntable 20 is rotatably connected to the outside of the rotating rod 19. A fixed threaded hole 22 is opened inside the turntable 20, and a fixing screw 21 is threadedly connected to the inside of the fixed threaded hole 22.

[0036] The turntable 20 is released from the fixing by rotating the fixing screw 21 , and the turntable 20 is rotated, and the handle 18 is pulled to take out the fixing frame 16 and the filter element 17 together for replacement and cleaning. The fixing threaded hole 22 is used to limit the fixing frame 16 and the turntable 20 .

[0037] Working principle: When the device is used, the smoke generated by the production is transferred to the smoke pipe 2 through the smoke exhaust pipe 1, and the smoke passes through the filter element 17 on the fixed frame 16, and the filter element 17 absorbs the large mass particles in the smoke. Then the smoke enters the processing chamber 14 through the air outlet 15 on the processing chamber 14, passes through the condenser 12, and the temperature in the cooling box 11 is reduced. Then the temperature enters the processing chamber 14 through the air pipe 13, and then drives the water pump 7 to make the water in the water tank 6 enter the sprinkler head 10 through the water pipe 9. In the process, water forms atomized water vapor through the spray head 10 and enters the processing chamber 14. The sprayed chemical solution further reduces the particle concentration and the smoke temperature. The smoke continues to flow into the smoke duct 2 through another air outlet 15 and is discharged. When the filter element 17 needs to be replaced and cleaned, the turntable 20 is disengaged by rotating the fixing screw 21, and the turntable 20 is rotated. The fixing frame 16 and the filter element 17 are taken out by pulling the handle 18, and then the filter element 17 is cleaned or replaced, thereby achieving the effect of easy cleaning or replacement.
