Dust removal equipment refers to the equipment that separates dust from flue gas, also known as dust remover. Everyone has the experience of wearing masks, which is a simple filtering and dust removal equipment. [1] The dust removal mechanism of dust removal equipment is very simple. Like the dust removal mechanism of mask, it is realized by mechanical interception of fly ash particles in flue gas by filter materials. However, in addition, the first received fly ash particles also form a stable and dense ash layer (generally referred to as filter cake or filter bed) on the surface of the filter material, which plays a good filtering role, especially the dust removal equipment using woven cloth as filter bag, which plays a main filtering role.
