P84 Bag Filters For Cement Dust Collector

The dust collector bag is the core element of the cylindrical impulse type dust collector bag is suspend in the dust collectors vertically.
Dust gas enters the dust hopper directly by inertia. When dust gas enters the dust collector bag from the air inlet and the passage board, making most big dust particle filtered out into the dust hopper directly by inertia. When dust gas reaches the filtering area of the box with dust collector bags , most dust is cap tured on the outer surface of the dust collector bags, and the gas flows into the pocket through filter. Media then purified gas discharges from the outlet.
The cage inside the pocket is used to support and prevent the pocket to collapse while it is helpful to remove and redistribute the dust cake.

P84 needled felt uses Austrian LENZIHG company produces P84 fiber (poly amide fibers) and the three dimensional acupuncture. which has a very Good high temperature resistance up to 260 'C, and P84 fiber cross section shows irregular leaf can greatly improve the filtering effect. Fiber taper itself has a resistance to hydrolysis, oxidation, which has a good temperature resistance, good filtering effect, and widely apply to concrete mixer, cement, waste incineration, using complex operating conditions such as coal-fired boiler.
