Its "This utility model uses a high-efficiency denitrification agent as a reducing agent, which, compared with reducing agents such as liquid ammonia, urea, and ammonia water, has the characteristics of being non-toxic and harmless." However, this denitrification treatment device still has the following drawbacks during use: The treatment device, with its denitrification agent flow pump, metering device, and injection mechanism, does achieve denitrification. However, this structure only allows for single-pass denitrification, which affects the denitrification quality of the flue gas. Therefore, it is necessary to provide a treatment device that facilitates cyclic denitrification and improves denitrification quality. Furthermore, the current device is not conducive to stirring the denitrification agent, leading to incomplete reaction, waste, and increased costs. Therefore, it is urgent to provide a treatment device that facilitates stirring the denitrification agent and reduces costs. Utility Model Content

[0028] In one specific embodiment, the denitrification component 100, in conjunction with the stirring component 200, not only performs circulating denitrification and filtration of the flue gas, thus ensuring the quality of flue gas denitrification, but also, through the cooperation of the above structures, allows for the recycling of the denitrification agent, improving utilization rate and reducing cost losses. In use, high-temperature flue gas is first conveyed into the installation cylinder 102 via the flue gas conveying mechanism 104. At this point, the filter element 105, in conjunction with the activated carbon filter plate 106, filters particulate matter in the flue gas.

[0042] In one specific embodiment, the bearing 222 can reduce the friction of the connecting shaft 204 and improve the smoothness of stirring.

[0043] Working principle: In use, high-temperature flue gas is first conveyed into the installation cylinder 102 through the flue gas conveying mechanism 104. At this time, the flue gas passes through the filter plate 106 and the filter element 105. The filter element 105, together with the activated carbon filter plate 106, can filter the particulate matter in the flue gas. Then, the servo motor 207 is started to drive the second bevel gear 208 to rotate, which in turn drives the first bevel gear 206 and its upper shaft 201, stirring rod 202, side rod 203 and connecting shaft 204 to rotate, thereby stirring the water and denitrification agent. At the same time, several stirring blades 205 rotate with the water flow, which can further stir the denitrification agent to thoroughly mix the water and the denitrification agent. The denitrification agent in the storage cylinder 101 is conveyed into the installation cylinder 102 through the liquid conveying mechanism 107, so that the denitrification agent is sprayed out in the form of mist and mixed with the flue gas, thereby enabling the flue gas to perform a circulating denitrification operation, thus ensuring the denitrification quality and reducing cost losses.
