The filter type dust collector refers to the equipment that realizes the separation of gas and solid when the dust-containing flue gas pores pass through the filter layer, and the dust particles in the airflow are blocked and captured by the filter layer.

The filter type dust removal device includes a bag filter and a particle layer filter. The former usually uses a filter bag made of organic fiber or inorganic fiber fabric as a filter layer, while the latter filter layer uses particles of different particle sizes, such as quartz sand, It is composed of river sand, ceramsite and slag.

A bag filter is a dry dust filtration device that uses a bag-like filter element made of fibrous fabric to capture solid particles in dust-laden gases. It is suitable for capturing fine, dry, non-fibrous dust. After the dust-laden gas enters the bag filter, the dust with large particles and heavy specific gravity settles under the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified.
