In recent years, with the continuous development of new technologies and new materials, the structure and filter material of the dust collector have been improved, so that the filter cartridge dust collector is widely used in cement, steel, electric power, food, metallurgy, chemical industry and other industrial fields. The overall capacity has increased several times, and it has become a large-scale dust collector with a filter area of > 2000m2 (GB6719-86 category). Compared with the existing bag-type and electrostatic precipitators on the market, the solution has the characteristics of large effective filtration area, low pressure difference, low emission, small size and long service life, and has become a new direction for the development of industrial dust collectors.
