[0002] Waste incineration power generation refers to a form of power generation that burns municipal solid waste in special incineration boilers and then generates electricity through steam turbine generator sets. This power generation method can effectively treat municipal waste and achieve resource recycling. During waste incineration, a large amount of flue gas is emitted. Flue gas is a mixture of gas and smoke, which is the main cause of air pollution and requires purification equipment to be used for its purification.

[0003] In the prior art, a flue gas treatment device for waste incineration power generation is disclosed with patent announcement number CN220834670U. The above patent utilizes a flue gas treatment box, a sealing cover, a filter element box, and a solid silicone sealing gasket to greatly improve the sealing inside the device. However, in actual use, the following deficiencies still exist: when the flue gas purification device is used for a long time, a large amount of smoke dust easily adheres to the internal filter structure, causing blockage of the filter structure, thereby affecting the subsequent continued filtration of the flue gas. At the same time, the filter element is usually fixedly arranged inside the purification device, resulting in a cumbersome disassembly and assembly process when repairing the damaged filter element.

[0004] Therefore, a flue gas purification device for a waste incineration power plant is needed to solve the problems in the prior art that the filter structure is easily clogged by smoke after long-term use and the filter element is difficult to disassemble and install quickly during maintenance.

[0023] The cleaning mechanism 5 includes a motor mounting frame 51, which is fixedly connected to the top surface of the fume hood 1. A servo motor 52 is installed on the motor mounting frame 51. The output end of the servo motor 52 is coaxially fixedly connected to a rotating wheel 53. The bottom of the outer wall of the rotating wheel 53 away from the servo motor 52 is fixedly connected to a pin rod 54. The sliding sleeve on the outer surface of the pin rod 54 is provided with a linkage sleeve 55. The center of the bottom surface of the linkage sleeve 55 is fixedly connected to a slide rod 56. The bottom of the slide rod 56 slides through the inner wall of the top surface of the fume hood 1 and two parallel brush plates 57 are fixedly connected to the right outer wall.

[0024] Further as Figure 1 and Figure 4 As shown, it is worth mentioning that the mounting assembly 6 includes a mounting block 61, the bottom surface of the mounting block 61 is fixedly connected to the top surface of the sealing baffle 4, a fixing screw hole 62 is opened on the left outer wall of the mounting block 61, a fixing screw 63 is inserted into the inner thread of the fixing screw hole 62, and a screw cap 64 is coaxially fixedly connected to the outer wall of the side of the fixing screw 63 away from the mounting block 61, two parallel positioning rods 65 are fixedly connected to the outer wall of the rear end of the mounting block 61, and a fixing plate 66 is threadedly connected to the outer surface of the fixing screw 63.

[0025] Further as Figure 1 and Figure 3 As shown, it is worth mentioning that a dust box 8 is fixedly connected to the bottom surface of the fume hood 1 , a collecting drawer 9 is slidably inserted into the dust box 8 , and a sealing door 10 is provided at the front end of the dust box 8 .

[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that a connecting pipe 11 is fixedly connected at the center of the outer wall of one side of the fume hood 1, a through groove 12 is opened through the outer wall of the bottom surface of the fume hood 1 near the filter plate 3, and positioning holes 13 that are compatible with the positioning rod 65 are opened at the top and bottom of the front outer wall of the fume hood 1.

[0027] Further as Figure 3 and Figure 4 As shown, it is worth mentioning that the bristles of the brush plate 57 are in contact with the outer wall of one side of the filter screen plate 3, and the servo motor 52 drives the rotary wheel 53 to rotate, so that the rotary wheel 53 pulls the slide rod 56 through the linkage sleeve 55 to drive the brush plate 57 to brush and clean the filter screen plate 3, and the rear end outer wall of the fixed plate 66 is fixedly connected to the front end outer wall of the smoke hood 1, so that it is convenient to rotate the screw cap 64 to drive the fixing screw 63 to separate from the mounting block 61, thereby releasing the fixed limit of the filter screen plate 3.

[0028] Further as Figure 1 、 Figure 3 and Figure 4As shown, it is worth mentioning that each positioning rod 65 is inserted into the corresponding positioning hole 13, which is convenient for quick positioning when installing the filter screen plate 3, and at the same time improves the stability of the filter screen plate 3 after installation. The through groove 12 is located directly above the collecting drawer 9, which facilitates the smoke and dust brushed off the filter screen plate 3 to fall into the collecting drawer 9 for collection.

[0029] In summary: before using the flue gas purification device, first connect the flue gas hood 1 to the exhaust pipe of the external incineration device through the connecting pipe 11, and make the connecting pipe 11 in a horizontal state. When using the flue gas purification device, turn on the servo motor 52, and the flue gas enters the inside of the flue gas hood 1 from the connecting pipe 11. When the flue gas passes through the filter plate 3 for discharge, the filter plate 3 filters and intercepts the smoke in the flue gas. At this time, the servo motor 52 drives the wheel 53 to rotate, and the wheel 53 drives the linkage sleeve 55 to move up and down reciprocatingly through the pin rod 54. The linkage sleeve 55 drives the brush plate 57 to brush the filter plate 3 up and down reciprocatingly through the slide rod 56. When the linkage When the movable sleeve 55 moves to the highest point, the brush plate 57 located below moves to the middle position of the filter screen plate 3, and the brush plate 57 located above moves to the top position of the filter screen plate 3, so as to achieve comprehensive cleaning of the filter screen plate 3, and brush off the smoke and dust attached to the filter screen plate 3 to prevent the smoke and dust in the smoke from clogging the filter screen plate 3. The fallen smoke and dust enter the collecting drawer 9 through the through groove 12 for collection. After a period of collection, the sealing door 10 is opened to remove the collecting drawer 9 from the dust box 8, so as to facilitate the centralized treatment of the smoke and dust collected in the collecting drawer 9, and the cleaning effect is good, which effectively avoids the problem that the filter structure is easily clogged by smoke and dust after long-term use.

[0030] When the filter panel 3 needs to be disassembled and repaired, the screw cap 64 is turned counterclockwise to drive the fixing screw 63 to rotate. Under the action of the thread, the fixing screw 63 moves on the fixing plate 66 in the direction away from the mounting block 61. When the fixing screw 63 is completely separated from the mounting block 61, the fixing limit of the mounting block 61 is released. After the two fixing screws 63 are operated in sequence, the fixing of the filter panel 3 is released. At this time, the filter panel 3 can be taken out of the smoke hood 1 by the handle 7, which is convenient for repairing the filter panel 3. Similarly, when the filter panel 3 is installed after repair, the filter panel 3 can be quickly positioned when it is inserted into the smoke hood 1 through the slot 2 by cooperating with the positioning rod 65 and the positioning hole 13. The filter panel 3 can be quickly positioned, and then the fixing screw 63 is turned clockwise to make it inserted into the fixing screw hole 62, so that the filter panel 3 can be quickly installed. The operation is simple and effectively avoids the problem that the filter element is difficult to disassemble and install quickly during maintenance.
