The exhaust gas is collected by the gas collecting hood, enters the main air pipe, and passes through the flame arrester to extinguish the sparks in the exhaust gas, and then the exhaust gas enters the bag filter system. Under the action of the diversion device, the large particles of dust are separated and fall directly into the ash hopper. The rest of the dust enters the filter area of each warehouse evenly with the airflow. The filtered clean gas passes through the filter bag and passes through the upper box, lift valve and exhaust pipe Discharge, and then through the induced draft fan to discharge the smoke and dust up to the standard. As the filtration progresses, when the dust on the surface of the filter bag reaches the thickness, the dust removal control device closes the poppet valve according to the set procedure, controls the current unit offline, and opens the electromagnetic pulse valve to blow off the dust on the filter bag. After the dust falling into the ash hopper is discharged through the ash discharge valve, it is sent out by the ash conveying system.

Smelting electric furnace dust collector equipment is widely used: the collection and filtration of high temperature flue gas dust such as melting aluminum, iron making, copper melting, zinc melting, and drying furnaces.
