[0029] The working principle of this embodiment is as follows: when in use, the flue gas enters the shell 1 through the flue gas inlet pipe 2, and the low-temperature plasma generated by the discharge electrode 10 after entering the shell contains high-energy electrons, which instantly generate strong oxidizing free radicals. After the flue gas flows to the multi-tube shell 12, SO2 and NOX are oxidized to form corresponding acids, and generate by-products with the ammonia added through the ammonia inlet pipe 3. After the formation, they are washed with water through the water washing inlet pipe 4. After water washing, the motor 7 is started. When the motor 7 works, it will drive the shaft 8 to rotate.

The purified flue gas is transported from the connecting pipe 16 to the flue gas exhaust pipe 17 through the suction pump 15. After transportation, the purified flue gas will be discharged from the flue gas exhaust pipe 17. The purified flue gas passes through the connecting pipe 16. When the filter element 20 is blocked, the particulate matter and other unreacted substances will be further filtered and purified by the filter element 20, thereby effectively preventing the particulate matter and other unreacted substances from being discharged with the flue gas, thereby improving the further treatment effect of the flue gas. At the same time, when the filter element 20 is blocked, the knob 28 can be turned to drive the threaded rod 26 to rotate inside the fixed shell 18 through the knob 28. During the rotation, the threaded rod 26 will drive the L plate 27 to slide on the outer wall of the limiting column 24. After sliding a certain distance, the L plate 27 will move away from the limiting groove 23. After moving away, the handle 22 is pulled again to drive the square plate 21 to move. During the movement, the square plate 21 will drive the plug block 19 to slide inside the fixed shell 18. After sliding a certain distance, the plug block 19 and the filter element 20 installed therein can be taken out for cleaning, thereby improving the maintenance efficiency of the filter element 20 and facilitating the operation of the operator.
