The pulse back-flush bag dust collector is an advanced bag-type high-efficiency bag type dust-removing device. It is a dust-removing device that handles large air volume, good cleaning effect, high dust removal efficiency, reliable operation, convenient maintenance and small floor space.
structure
The pulse backflush bag dust collector is composed of a filter bag assembly, a flow guiding device, a pulse blowing system, an ash discharging system, a control system, an offline protection system, a box body and the like.
principle
The dust-containing gas enters each unit chamber by the diversion tube. Under the action of the flow guiding device, the large particle dust separates directly into the ash bucket, and the remaining dust uniformly enters the filter chamber of the chamber with the airflow, and the filtered clean gas is filtered through. The bag is discharged through the upper box, the poppet valve, and the exhaust duct. As the filtration condition progresses, when the surface dust of the filter bag reaches a certain thickness, the lifting valve is closed by the cleaning control device (differential pressure or timing, manual control) according to the setting program, the current unit is controlled to be offline, and the electromagnetic pulse valve is opened. Spray and shake off the dust on the filter bag. The dust falling into the ash hopper is discharged through the ash discharge valve and sent out by the ash conveying system.
Application range
The pulse backflush bag dust collector series serves the air purification and material recovery of metallurgy, electric power, building materials, ore, cement, chemical, carbon black, asphalt concrete mixing, boiler and other industries with excellent performance.
