[0002] Nitrogen oxides are major air pollutants, including NO, NO2, N2O, etc., which can cause acid rain, photochemical smog, greenhouse effect and ozone layer destruction. 63% of NOx in nature comes from industrial pollution and traffic pollution, which is twice the natural source. Among them, the power industry and automobile exhaust emissions each account for 40%, and other industrial pollution sources account for 20%. Under normal combustion temperatures, more than 90% of the NOx produced during the combustion process is NO, NO2 accounts for 5% to 10%, and there is a very small amount of N2O. NO discharged into the atmosphere is quickly oxidized into NO2, causing respiratory diseases and causing harm to human health;

[0003] In industrial production, NOx is mainly generated during the combustion of fuel. In the prior art, selective catalytic reduction technology (SCR) is generally used. Under the action of a catalyst, a reducing agent ammonia or urea is sprayed into the flue gas to reduce the NOx in the exhaust gas to N2 and H2O. In order to clean the flue gas, adsorption and filtration treatment are required to remove odor and internal particulate impurities. A variety of independent purification equipment are required for treatment. Since the transmission of flue gas between different equipment is easily affected by various factors such as the external environment, there are errors in the coordinated management of each equipment. At the same time, the denitrification performance factors of the SCR method are mainly restricted by the following points: the mixing degree of flue gas and ammonia, catalyst blockage, etc., especially catalyst blockage. In the prior art, manual maintenance or replacement is required, which is troublesome. Therefore, the utility model proposes a multi-pollutant coordinated management device to solve the problems existing in the prior art. Utility Model Content
