The bag-type dust collector is a new product developed by utilizing pulse filter bags as the filtering element to achieve air dust removal and industrial powder (smoke) dust removal. It features advanced technology, compact structure, compliance with emission standards, small land occupation, low investment, and low operating costs. The pulse filter bag dust collector is widely applicable for dust removal in the intake of blast furnace blowers, oxygen generators, air compressors, main control rooms, clean workshops, air intake of air conditioners in public buildings, and medium-low concentration smoke (air) dust removal. It can also be used for the purification and treatment of industrial dust in industries such as iron and steel metallurgy, non-ferrous smelting, building materials, mechanical casting, food and light industry, daily chemical products, tobacco, storage and docks, industrial power station boilers, heating boilers, and municipal waste incineration.
