[0002] During the industrial production process, flue gas containing nitrate will be generated. Directly discharging it into the air will cause huge pollution to the environment. Therefore, the flue gas needs to be denitrated before it can be discharged. At present, the selective catalytic reduction (SCR) method is the most widely used and most mature flue gas denitrification technology. In this technology, the denitrification reactor is the core device of the SCR device, providing a place for NOX and NH3 in the flue gas to generate N2 and H2O on the catalyst surface. The key to the SCR denitrification device is how to ensure that the flow field, temperature field and concentration field (NH3 / NOx) of the flue gas in the reactor are as uniform as possible, so as to ensure that the required denitrification efficiency is achieved and the amount of ammonia escape is reduced.

[0003] In the prior art, for example, Chinese patent publication number CN219984379U discloses a modular denitration reactor, including a treatment box, a plurality of supporting legs are fixedly installed at the bottom of the treatment box, an ammonia preparation and storage box is fixedly installed at the top of the treatment box, a fixed box is fixedly installed at the upper right side of the treatment box, and a rotating groove 1 is opened on the upper inner side of the treatment box, and a rotating plate is inserted and installed in the rotating groove 1. The utility model provides a treatment box, an ammonia preparation and storage box, etc., and introduces flue gas into the interior of the treatment box, and drives the rotating plate and the stirring wind main board and the stirring wind wing plate to rotate with a rotating mechanism, thereby improving the fluidity of the air, quickly mixing and interacting the flue gas and ammonia, and distributing them uniformly, which helps to improve the denitration efficiency.
