FEATURES:
The IBL Pulse Jet Bag Filter.
• The pulse-jet bag file in its most primary form consists essentially of the filtration elements housed in a casing. Beneath this housing is a hopper with a drain valve to continuously remove dust that has accumulated on the hoses. The entire unit is supported from the floor on structural feet. A ladder with cage allows access to the upper part of the unit for maintenance.
• The dust-laden settles on the outside of the bags while the clean air raises from the centre of the bags through the discharge plenum to the top air outlet. This is called filtration. Dust that has accumulated on the outside surface of the bags is removed in a predetermined cycle by a momentary pulse of high pressure compressed air.
• The compressed air flows from an air receiver or a compressed air manifold through a special pulse valve into the manifold and from there into the bags in the row below. The pressurised air flows through the venturi nozzles into the bags, inflating them, and the dust cake that forms on the surface of the bags slides down in the form go flakes. The cages help the bags to retain their original shape once the effect of the compressed air has disappeared. This completes the cleaning process. The dust slides down the hopper walls to the rotating air lock valve.
• Cages are wire frames placed inside pulse jet filter elements to support the mesh as it flews during filtration and cleaning cycles. The configuration of a frame generally follows the shape of the filter elements, i.e round, oval, apartment or star-shaped. Cages for long filter elements are made in sections that snap together for easier handling.
