[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-4 As shown, a flue gas online continuous monitoring sampling flue gas filtering device comprises an exhaust pipe 15, a filter cartridge 1 is arranged on the exhaust pipe 15, a filter cover 11 is arranged on the filter cartridge 1, a plurality of swing plates 17 arranged in a circular array are arranged in the filter cover 11, an extension plate 18 is arranged at the bottom of the swing plate 17, and a cleaning portion 19 is arranged at the bottom of the extension plate 18;

[0023] The cleaning portion 19 includes a connecting plate 192 fixedly disposed on the extension plate 18 , and scratching plates 193 are symmetrically disposed on both sides of the connecting plate 192 . The scratching plates 193 are right-angled triangles, and their hypotenuses are in contact with the inner wall of the filter cartridge 1 .

[0024] Specifically, when in use, the filter cartridge 1 is installed on the exhaust pipe 15, and then water is connected to the filter cover 11. Then, the water flow impacts the swing plate 17, causing the swing plate 17 to rotate in the filter cover 11, thereby driving the extension plate 18 to rotate, and then driving the connecting plate 192. The connecting plate 192 is attached to the inner wall of the filter cartridge 1, and then the scratch plates 193 on both sides of the connecting plate 192 scratch the inner wall of the filter cartridge 1 to clean the impurities on the inner wall of the filter cartridge 1.

[0025] In the above scheme, the smoke is filtered by the filter cartridge 1 on the exhaust pipe 15, and the swing plate 17 is driven by water flow, thereby driving the extension plate 18 and the cleaning part 19 to rotate synchronously, and the inner wall of the filter cartridge 1 is scraped by the connecting plate 192 in the cleaning part 19, and the inner wall of the filter cartridge 1 is scraped by the scratching plate 193 on the connecting plate 192, so that the impurities on the inner wall of the filter cartridge 1 are scraped and removed.

[0026] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, the swing plate 17 forms a cross shape, and the exhaust fan 13 is fixedly installed at the intersection.
