DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a flue gas treatment device for waste power generation, including a collection support 100, a detachable filtering component 200 is installed on the collection support 100, and a cleaning component 300 is arranged inside the filtering component 200;

[0023] The filtering component 200 includes a smoke inlet pipe 204. One end of the smoke inlet pipe 204 is sleeved with a filtering inner cylinder 206. The outer side of the filtering inner cylinder 206 is sleeved with a filtering outer cylinder 201. The outer diameter of the filtering inner cylinder 206 is smaller than the inner diameter of the filtering outer cylinder 201. An inner slag discharge hole 207 is formed at the lower end of the outer side of the filtering inner cylinder 206. An outer slag discharge hole 208 is formed at the lower end of the outer side of the filtering outer cylinder 201. The outer slag discharge hole 208 is arranged directly below the inner slag discharge hole 207. The filtering outer cylinder 201 is communicated with a connecting cover 209 through the outer slag discharge hole 208. The cross section of the connecting cover 209 is trapezoidal.

[0024] One end of the outer side of the smoke inlet pipe 204 is fixedly connected with a limiting ring 205 that abuts against the filtering inner cylinder 206. The outer diameter of the limiting ring 205 is smaller than the inner diameter of the filtering inner cylinder 206. By restricting the position of the filtering inner cylinder 206 through the limiting ring 205, the stability of the filtering inner cylinder 206 is improved.

[0025] The axes of the filtering inner cylinder 206, the filtering outer cylinder 201, and the smoke inlet pipe 204 are all arranged on the same straight line. Both ends of the filtering outer cylinder 201 are open. Multiple groups of positioning bolts 203 are inserted at both ends of the filtering outer cylinder 201. Through the multiple groups of positioning bolts 203, it is convenient to install the filtering outer cylinder 201 in the collection support 100, and the disassembly and assembly are convenient, which is convenient for later maintenance.

[0026] The collection support 100 includes a support frame 101. The support frame 101 is in a U-shaped setting. Sealing gaskets 202 that abut against the inner cavity of the support frame 101 are arranged at both ends of the filtering outer cylinder 201. Multiple groups of positioning bolts 203 all penetrate through the sealing gaskets 202 and are bolted to the support frame 101. Through the sealing gaskets 202, the sealing performance between the support frame 101 and the filtering outer cylinder 201 is improved, thereby avoiding the leakage of flue gas, enabling the filtering inner cylinder 206 and the filtering outer cylinder 201 to double-filter impurities from the flue gas, and improving the filtering effect.

[0027] A storage groove 102 communicated with the connecting cover 209 is formed at the bottom of the inner cavity of the support frame 101. A side hole 103 is formed on one side of the support frame 101. A collection drawer 104 is inserted into the side hole 103. An insertion hole 105 for installing the smoke inlet pipe 204 is formed on one side of the support frame 101. Through the storage groove 102, it is convenient to store the collection drawer 104. The collection drawer 104 is convenient for storing the cleaned impurity particles, so as to centrally process the collected impurity particles and reduce the cleaning intensity of the staff.

[0028] The cleaning assembly 300 includes a motor 301 installed on the other side of the support frame 101, the output shaft of the motor 301 is drivingly connected to a rotating shaft 302 located in the inner cavity of the support frame 101, and multiple groups of internal cleaning parts 303 are arranged on the outer side of the rotating shaft 302, and a sealing plate 304 is fixedly connected to the outer side of one end of the rotating shaft 302 close to the motor 301, and one side of the sealing plate 304 is fixedly connected to an outer ring 305 that slides with the outer side of the outer filter cylinder, and one side of the sealing plate 304 is fixedly connected to multiple groups of support plates 306, and external cleaning brushes 307 are arranged on both sides of the multiple groups of support plates 306. The rotating shaft 302 is driven by the motor 301, thereby driving the internal cleaning part 303 to clean the inner wall of the filter inner cylinder 206, and at the same time, the sealing plate 304 drives the external cleaning brush 307 on the support plate 306 to clean the outer wall of the filter inner cylinder 206 and the inner wall of the filter outer cylinder 201, thereby improving the cleaning efficiency of attached impurities.

[0029] The multiple groups of internal cleaning parts 303 all include two groups of connecting rods 3031 fixedly connected to the outside of the rotating shaft 302 and internal cleaning brushes 3032 fixedly connected to the two groups of connecting rods 3031. The internal cleaning brushes 3032 are in conflict with the inner wall of the filter inner cylinder 206. The two groups of external cleaning brushes 307 are in conflict with the outer side of the filter inner cylinder 206 and the inner wall of the filter outer cylinder 201 respectively. The multiple groups of support plates 306 are arranged at equal angles. Through the double cleaning of the internal cleaning brush 3032 and the external cleaning brush 307, the cleaning efficiency of the filter inner cylinder 206 and the filter outer cylinder 201 is improved, the permeability of the meshes of the two is guaranteed, and the filtering of the flue gas is facilitated.

[0030] When in use, the smoke exhaust pipe is connected to the smoke inlet pipe 204, so that the smoke passes through the smoke inlet pipe 204 into the filter inner cylinder 206 of the filter assembly 200. In the process of the smoke flowing upward, the impurity particles in the smoke will accumulate on the inner wall of the filter inner cylinder 206, and the smaller impurity particles will enter the filter outer cylinder 201, and then the filter outer cylinder 201 will block the smaller particle impurities to facilitate the filtering of the smoke, improve the filtering effect of the smoke, and drive the rotating shaft 302 through the motor 301 to drive The multiple groups of internal cleaning parts 303 and the sealing plates 304 rotate, and the multiple groups of internal cleaning parts 303 clean the impurity particles attached to the inner wall of the filter inner cylinder 206. The sealing plates 304 drive the external cleaning brushes 307 on the support plates 306 to clean the outer wall of the filter inner cylinder 206 and the inner wall of the filter outer cylinder 201, so that the cleaned impurity particles pass through the internal slag discharge holes 207 and the external slag discharge holes 208 and fall into the collecting bin 104 via the connecting cover 209, which is convenient for collecting and processing the cleaned impurity particles and improving the efficiency of flue gas treatment.
