[0023] When in use, the flue gas in the oxidation furnace body 2 is transported into the dust removal tank 4 through the smoke inlet pipe 3, and the driving component 84 is started, so that the first connecting rod 82 fixedly installed on the symmetrically arranged support frame 81 inside the dust removal tank 4 drives the first filter plate 83 to vibrate, and then the driving component 84 cooperates with the connecting component 86 arranged on the first filter plate 83 and the second filter plate 85 to make the second filter plate 85 vibrate as well. The dust-removed flue gas flows into the denitrification tank 6 through the connecting pipe 5 fixedly arranged on the top of the dust removal tank 4 for treatment, and then is discharged through the smoke outlet pipe 7.

[0024] Specifically, the driving assembly 84 includes a driving motor 841 fixedly arranged on one side of the top of the first filter plate 83 and located below the support frame 81, a rotating shaft 842 rotatably arranged on the driving motor 841, connecting rods 843 symmetrically hinged at both ends of the rotating shaft 842, a rotating rod 844 hinged at the other ends of the two connecting rods 843, and two connecting blocks 845 rotatably sleeved on the outside of the rotating rod 844 and located on one side of the top of the second filter plate 85; the connecting assembly 86 includes fixed blocks 861 symmetrically arranged on both sides of the first filter plate 83 and the second filter plate 85, and a second connecting rod 862 hinged on the two fixed blocks 861;

[0025] When the flue gas is subjected to dust removal and denitrification, smoke dust will adhere to the first filter plate 83 and the second filter plate 85 in the dust removal tank 4, and the driving motor 841 is started, so that the first connecting rod 82 hinged on the support frame 81 drives the first filter plate 83 to vibrate.

[0029] When the flue gas coming out of the oxidation furnace body 2 is processed by the dust removal tank 4, it is passed into the denitrification tank 6 through the connecting pipe 5. The ammonia generating device 62 fixedly installed on one side of the denitrification tank 6 is used to transport the ammonia into the denitrification tank 6 through the ammonia transport pipe 61, and then adsorbed by the activated carbon plate 63 to remove pollutants. The denitrified gas flows out of the denitrification tank 6 through the smoke outlet pipe 7 fixedly set on one side of the denitrification tank 6.
