Dust removal equipment, the dust separated from the flue gas equipment, also known as the precipitator. We have the experience of wearing a mask, a mask is a simple filter dust removal equipment. Dust removal mechanism of dust removal equipment is very simple, it masks for dust removal mechanism is through the filter material to achieve the mechanical interception of fly ash particles in the flue gas. In addition, the first received fly ash particles in the filter surface also formed a stable layer of dense gray layer (commonly known as filter cake or filter bed), it played a very good filter, especially to do with the preparation of cloth filter bag dust removal equipment, this layer of the filter bed has played a major role in filtering.
