The existing dust remover mainly adopts a single dust removal mode. This single dust removal mode has the problems of low dust removal efficiency and small particle size range. When the dust concentration is high, the equipment is prone to blockage, and particulate matter is easy to accumulate on the inner wall of the equipment, which seriously affects the dust removal effect. At the same time, the existing dust remover has insufficient processing capacity for fine particulate matter, and cannot meet the processing needs of dust of different particle sizes, resulting in poor dust removal effect, short service life and high maintenance cost.

As the dust on the filter bag increases, the resistance gradually rises to a certain value, and then the dust is cleaned. The dust cleaning vibration system starts to work according to the dust cleaning program. When vibrating, the weight impacts and vibrates the single frame to make the dust attached to the filter bag fall off and settle in the hopper. The rotating air lock at the outlet of the hopper gradually discharges.

Since only filter bags are used for filtration, the treatment effect of fine particulate matter is not ideal, and the filter bags are prone to blockage, which requires frequent dust cleaning and maintenance, increasing the maintenance cost of the equipment.
