Single machine dust collector produced by Hebei Feixiang Environmental Protection Equipment Co., Ltd; working principle:
When the dusty gas enters the dust collector through the air inlet, it first encounters the inclined plate and baffle in the middle of the air inlet and outlet, and the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down, and due to inertia, the coarse particles of dust in the gas directly flow into the ash hopper. Plays a role in pre collecting dust, the airflow entering the ash hopper is then deflected upwards and captured on the outer surface of the filter bag with a metal frame inside. The purified gas enters the upper clean room of the filter bag chamber and is collected at the air outlet for discharge. During the purification process of dusty gas through filter bags, as time increases, more and more dust accumulates on the filter bags, causing the resistance of the filter bags to gradually increase and the processing air volume to gradually decrease. To work normally, the resistance should be controlled within a range (140-170 mm water column). At this time, when the resistance rises to the limited range, the pulse controller sends instructions to trigger each control valve to open the pulse valve in sequence. The compressed air in the air bag is sprayed into each corresponding filter bag through the holes of the blowing tube through the Venturi tube, and the filter bag expands rapidly in an instant, causing the dust accumulated on the surface of the filter bag to fall off, and the filter bag is cleaned. Clean up the dust that falls into the ash hopper and is discharged from the machine through the ash discharge system. The dust accumulated on the filter bag is periodically pulse blown to clean the dust, allowing the purified gas to pass through normally and ensuring the normal operation of the dust collector.
