[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] Reference Figure 1-4 A waste gas filtering device for an air pollution prevention and control project comprises a pipeline 1, which is arranged horizontally, an air inlet is opened at one end of the pipeline 1, and an air outlet is opened at the other end of the pipeline 1. A filter plate 2 is detachably installed inside the pipeline 1, and a collecting tank 3 is detachably installed at the lower part of the interior of the pipeline 1. The collecting tank 3 is located on a side of the filter plate 2 close to the air inlet, and a cleaning mechanism is arranged above the collecting tank 3.

[0023] The cleaning mechanism comprises a brush 6, which is arranged on one side of the filter plate 2 close to the air inlet. The brush 6 is in contact with the filter plate 2, and a moving component is arranged outside the brush 6.

[0024] The moving assembly includes a support plate 4, which is arranged above the collecting tank 3, the support plate 4 is arranged horizontally, the support plate 4 and the brush 6 are fixedly connected, the upper end surface of the support plate 4 away from the filter plate 2 is inclined, and a power part is arranged above the support plate 4.

[0025] The power part includes an electric push rod 5 , which is fixedly installed above the pipeline 1 , and an output end of the electric push rod 5 passes through the pipeline 1 and extends to the inside of the pipeline 1 , and the output end of the electric push rod 5 is fixedly connected to the support plate 4 .

[0026] When the utility model is in use, the exhaust gas enters the interior of the pipe 1 through the air inlet and is discharged through the air outlet. In this process, the exhaust gas passes through the filter plate 2, and the filter plate 2 can filter the exhaust gas. The electric push rod 5 is connected to the external power supply. The electric push rod 5 drives the brush 6 to rise and fall through the support plate 4. When the brush 6 moves downward, it can brush the impurities attached to the surface of the filter plate 2 into the interior of the collection tank 3. It should be noted that the interior of the collection tank 3 is filled with water. When the brush 6 moves upward, the brush 6 can drive the impurities attached to the surface of the filter plate 2 to move upward. Since the upper end surface of the support plate 4 away from the filter plate 2 is inclined, the impurities above the support plate 4 can slide along the surface of the support plate 4 into the interior of the collection tank 3.

[0027] Furthermore, two groups of support frames 7 are slidably inserted inside the collecting tank 3 . The support frames 7 are hollow and connected to the support plate 4 via a pusher. A stirring structure is provided inside the support frames 7 .

[0028] The pusher includes a connecting rod 10 , one end of the connecting rod 10 is rotatably connected to the support frame 7 , and the other end of the connecting rod 10 is rotatably connected to the center of the support plate 4 .

[0029] The stirring structure includes a fixed plate 8 and a fan 9. The fixed plate 8 is fixedly installed at the center of the supporting frame 7. The fan 9 is rotatably inserted in the supporting frame 7. The fan 9 and the fixed plate 8 are rotatably connected.

[0030] When the utility model is in use, the support plate 4 can push the two groups of connecting rods 10 to rotate when moving downward, and the angle between the two groups of connecting rods 10 increases, thereby pushing the two groups of supporting frames 7 away from each other. When the support plate 4 moves upward, the angle between the two groups of connecting rods 10 decreases, thereby being able to drive the two groups of supporting frames 7 to approach each other. Under the action of the fixing plate 8 and the water flow, the supporting frame 7 can drive the fan 9 to rotate when moving, which is beneficial to stirring the impurities and water together, so that the impurities will not float on the water surface and the impurities will not accumulate in one place.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
