[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] like Figures 1-5 As shown in this embodiment, an ultra-low emission flue gas online monitoring device includes a monitoring box 1, with a fixing seat 4 on the side of the monitoring box 1 for fixing the device to the flue; a gas supply pipe 10, which is disposed inside the monitoring box 1; a flue gas analyzer 12, which is disposed on the gas supply pipe 10 and is used to analyze the content of various exhaust gases in the ultra-low emission flue gas; and a filtration mechanism, which includes a filter cylinder 8 and a filter screen 9. The filter cylinder 8 is disposed on the gas supply pipe 10, and the filter screen 9 is cylindrical. The filter cylinder 8 and the filter screen 9 are magnetically connected. The filter cylinder 8 includes a cylinder body 81, one end of which is closed, and the other end is provided with a fixing ring 82. Several first magnets 83 are provided on the outside of the fixing ring 82. The filter screen 9 includes a mesh body 91, and one end of the mesh body 91 is provided with a sealing plate 9. 2. The inner side of the sealing plate 92 is provided with several second magnets 93 corresponding to the first magnet 83. The end of the sealing plate 92 away from the mesh body 91 is provided with a connecting rod 94, and the end of the connecting rod 94 away from the sealing plate 92 is provided with a handle 95. When removing the filter screen 9, pull the handle 95, the first magnet 83 and the second magnet 93 separate, the filter screen 9 separates from the filter cylinder 8, and the removal of the filter screen 9 is completed. When installing the filter screen 9, insert the clean filter screen 9 into the filter cylinder 8, and then make the sealing plate 92 fit with the fixing seat 4.
