Background

In the process of flue gas treatment, in order to remove nitrogen oxides in flue gas, an SCR system with a mature technology is generally selected, and the system sprays reducing agent ammonia or urea under the action of a catalyst, and reduces the nitrogen oxides into nitrogen and water at high temperature or low temperature, so that the purposes of energy conservation and emission reduction are achieved, and the system has the advantages of high denitration efficiency, good selectivity and the like.

However, since the catalyst is used as a medium in the reaction process, the catalyst is deactivated after a period of time in which the catalyst is used in the flue gas. The current academic belief is that the main causes of catalyst deactivation include fly ash plugging, catalyst poisoning, catalyst attrition and sintering, among others. The existing catalyst regeneration method generally adopts the following process flows: cleaning the surface of the catalyst → placing the catalyst in an acid solution for activation treatment → distributing the impregnation solution in the SCR catalyst under a vacuum environment → drying and roasting the SCR catalyst after homogenization treatment to obtain the regenerated catalyst. That is, the current method for regenerating the catalyst in the fire still needs water washing and drying treatment after water washing so as to meet the requirement of the subsequent processing process. However, in the washing process, surface deposits which are fumigated and dyed by smoke for a long time still exist, and the washing process is not smooth, so that the regeneration effect of the catalyst in the subsequent links is not ideal.
