Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Therefore, the application of this technology is very beneficial to the purification of ambient air. Currently known flue gas desulfurization and denitration technologies include PAFP, ACFP, pyrolusite method, electron beam ammonia method, pulsed corona method, gypsum wet method, catalytic oxidation method, microbial degradation method, etc. In factories with a large amount of flue gas such as coal power plants, the application of desulfurization and denitration devices and related technologies is very important.

[0003] When the existing generated flue gas passes through catalytic reduction treatment, it will first pass through the filter bag inside the filtering part for preliminary filtering treatment. However, when the existing filter bag is used for a long time, the generated dust is easy to adsorb and accumulate on the surface of the bag, and in severe cases, it is easy to affect the gas filtration passing efficiency.
