[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Specifically, Figure 2As shown, when the internal particulate matter of the particulate trap 404 accumulates to a certain extent, the valve is closed and the burner 403 is opened. The flame generated by the burner 403 burns the particulate matter adsorbed on the particulate trap 404 into carbon dioxide, and then the valve is opened to discharge it.

[0023] Specifically, Figure 2 As shown, the vacuum cleaner 406 is a vacuum cleaner specially used for industrial production operations. It uses internal energy to drive the fan to rotate to generate negative pressure, suck out the exhaust gas inside the temporary storage box 405, and send it to the air intake plate, and finally blow it to the cylindrical filter 407 through the air blowing pipe.

[0024] Specifically, Figure 3 As shown, after the motor 409 is turned on, the motor 409 will rotate the gear rod 410. Since the outer surface of the gear rod 410 is meshed with the outer surface of the gear ring 408, the gear ring 408 will be driven to rotate, thereby driving the cylindrical filter 407 to rotate through the rotation of the gear ring 408.

[0025] When implementing, follow these steps:

[0026] 1) First, the exhaust gas is sent to the inside of the equipment box 1 through the air intake pipe for treatment;

[0027] 2) The exhaust gas will then undergo preliminary dust removal and purification under the action of the oxidation catalyst 401, the catalytic reducer 402 and the particle trap 404;

[0028] 3) Turn on the vacuum cleaner 406 and the motor 409, and extract the preliminarily treated exhaust gas through the vacuum cleaner 406 and send it to the cylindrical filter 407, while the motor 409 drives the cylindrical filter 407 to rotate;

[0029] 4) Finally, turn on the back-blowing machine 411 to cooperate with the main air duct and the back-blowing pipe to blow the dust on the outer surface of the rotating middle cylinder filter 407 into the dust collecting box for collection.

[0030] In summary, in the high-temperature dust removal equipment, when the exhaust gas enters the oxidation catalyst 401 through the air intake pipe, harmful substances in the exhaust gas will be converted into harmless substances through oxidation-reduction reaction in the oxidation catalyst 401, and then the exhaust gas treated by the oxidation catalyst 401 enters the catalytic reducer 402, and the nitrogen oxides are converted into nitrogen and water through the action of the catalyst, and then enters the particle collector 404, and the particulate matter in the exhaust gas will be captured in and on the wall of the carrier through interception, collision, diffusion, gravity sedimentation, etc., and finally enter the temporary storage box 405 for temporary storage, and then turn on the vacuum cleaner 406 and the motor 409 to send the exhaust gas to the air intake plate, and then blow it to the outer wall of the cylindrical filter 407 by the air blowing pipe, and use the cylindrical filter 407 to filter the exhaust gas again, and then turn on the back-blowing blower 411 to cooperate with the main air duct and the back-blowing pipe to blow off the dust on the cylindrical filter 407, and finally fall into the dust bag box for temporary storage, thereby achieving the purpose of dust removal.
