The activated carbon plate 20 is bolt - connected to the treatment tank 1 through the fixed bolts 21. Through the fixed bolts 21, it is convenient to replace the activated carbon plate 20.

[0026] As Figure 2 shown, a driving motor 8 is fixedly connected to the top inside the speed limit tank 2. The output end of the driving motor 8 is fixedly connected to the top end of the screw conveyor 3. A groove 9 is opened at the bottom end of the inner wall of the treatment tank 1. An inclined filter screen 12 is provided at the bottom end of the groove 9. A water guide groove 10 is provided below the filter screen 12.

[0027] As Figure 2 shown, the output end of a water pump 14 is fixedly connected to a tee 15. The top surface of the tee 15 is rotatably connected to the bottom end of the speed limit tank 2. A water guide pipe 16 is fixedly connected to the side surface of the tee 15. Through the tee 15, it is convenient to carry out the shunt treatment of the solution, achieving more thorough waste gas purification.

[0028] As Figure 1 and Figure 2 shown, a water pump 14 is fixedly connected below the treatment tank 1. The input end of the water pump 14 communicates with the bottom end of the water guide groove 10. An inclined sewage discharge hole 11 is opened on one side of the groove 9.

The solution inside the treatment box 1 is sucked into the water pump 14 through the water guide groove 10 by the water pump 14. The solution is introduced into the tee 15 through the output end of the water pump 14. The solution is split into the water guide pipe 16 and the rotating rod of the auger 3 through the tee 15. The solution is sprayed out through the nozzles 17 by the diversion of the water guide pipe 16. The solution flowing into the auger 3 is sprayed out through the first water flow holes 4.

[0031] At this time, the gas is introduced into the speed limit box 2 through the connecting pipe 19, and then the auger 3 is driven to rotate by the driving motor 8. The exhaust gas inside the speed limit box 2 first undergoes speed-limited flow through the rotation of the auger 3, and the first treatment is carried out by spraying water vapor through the atomizing spray holes 4. The water vapor is discharged into the box through the water flow holes 5 due to the rotation of the auger 3. Then the exhaust gas moves upward and is sprayed out through the air outlet 7. At this time, the water vapor sprayed by the nozzles 17 further treats the exhaust gas. Finally, the exhaust gas passes through the activated carbon plate 20 for the last step of treatment. The treated exhaust gas is discharged out of the box through the air outlet pipe 22. This article highlights the innovative structure and does not elaborate too much on the prior art.
