Seek more than 400 square meters "sintering machine" (not boiler) dust removal equipment working principle, related data, pictures, common failures and treatment methods and other information.

The working principle of bag filter When the dusty gas enters the dust hopper from the air inlet, a part of the coarser dust particles fall into the dust hopper due to inertial collision, natural sedimentation, etc. Most of the dust particles rise to the bag chamber with the airflow, and the dust particles are blocked on the outside surface of the filter bag after filtration by the bag, and the purified gas enters into the box from the inside of the filter bag, and is then discharged into the atmosphere through the hole of the valve plate and the outlet to achieve the purpose of removing the dust. As the filtration process continues, the accumulation of dust on the outside of the filter bag gradually increases, and the operating resistance of the bag type dust collector gradually rises, when the resistance reaches the pre-set value, the cleaning controller sends out a signal, first of all, to control the lifting valve will be closed to cut off the filtering of the airflow to stop the filtration process, and then the battery pulse valve is opened to spray compressed air into the box in a very short period of time, and the compressed air expands rapidly inside the box, and rushes into the inside of the filter bag. The compressed air expands rapidly in the box, rushes into the filter bag inside, makes the filter bag produce deformation, vibration, plus the role of the reverse airflow, the dust on the outside of the filter bag will be removed into the dust hopper. After the dust is cleaned, the lifting valve opens again, and the dust collector enters the filtering state again. The dust removal control of this equipment bag type dust collector is controlled by two kinds of control methods, namely, timed and fixed resistance.
