[0002] Low-temperature denitrification refers to the process of removing nitrogen oxides from flue gas by chemical or physical methods under low-temperature conditions. The generation of nitrogen oxides will consume oxygen in the atmosphere and produce photochemical smog, so it needs to be controlled.

The arrangement of the bristles can improve the contact effect between the cleaning plate 8 and the filter plate 5, thereby greatly ensuring the cleaning quality of the cleaning plate 8;

[0033] Example 2

[0034] like Figure 1 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a transmission assembly 9;

[0035] In this embodiment, the transmission assembly 9 includes a stabilizing frame 10, a linkage shaft 11, a transmission shaft 12, a transmission bevel gear 13 and a matching bevel gear 14. The interior of the denitrification tank body 1 is fixedly connected with the stabilizing frame 10, one end of the stabilizing frame 10 is vertically rotatably connected with the linkage shaft 11, and the cleaning shaft 7 is also slidably connected to the interior of the linkage shaft 11.

[0036] Furthermore, a limiting groove is provided on the outer side of the cleaning shaft rod 7, a limiting strip is fixedly connected to the middle part of the linkage shaft rod 11, and the limiting strip is also slidably connected inside the limiting groove. By utilizing the structural cooperation between the limiting groove and the limiting strip, during the rotation of the linkage shaft rod 11, since the limiting strip is located inside the limiting groove, the limiting strip can drive the cleaning shaft rod 7 to rotate accordingly;

[0037] Preferably, an assembly ear is fixedly connected to the outer side of the denitration tank body 1, and the transmission motor 15 is connected to one end of the assembly ear by bolts. The arrangement of the assembly ear enables the transmission motor 15 to be stably assembled and facilitates subsequent maintenance;
