Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag denitrification technology, specifically to an integrated dust collector filter bag denitrification reaction device. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material. They are made from raw materials such as polyester staple fiber, PPS fiber, PP polypropylene, aramid fiber, and aramid fiber. Their service life is generally 2-4 years. They have advantages such as good air permeability, high dust collection efficiency, and certain resistance to acid, alkali, and heat.

[0003] The patent CN215539825U discloses an integrated flue gas denitrification and dust removal device. This patent discloses a convenient replacement technical solution, which solves the problem that the existing metal fiber filter bags are only about 1 mm thick, so the denitrification reaction time is too short, resulting in very low denitrification efficiency, with a maximum denitrification efficiency of only 70%. This cannot meet the denitrification efficiency requirements for high nitrogen oxide concentrations. Moreover, once individual metal filter bags are damaged, the entire metal filter bag must be replaced and the denitrification catalyst module cannot be reused.

[0004] When in use, the denitrification catalyst module can be easily disassembled and assembled by fitting the filter bag inside the denitrification catalyst module. However, after prolonged use, the filter bag is prone to clogging by impurities in the flue gas, reducing the denitrification effect. Therefore, an integrated dust removal filter bag denitrification reaction device is proposed to solve the above problems. Utility Model Content
