5.0 THEORY OF OPERATION
5.1 During normal operation, dirtied air is pulled into the top section of the cartridge collector cabinet. The cabinet design distributes the dirty air uniformly above the vertically arranged filter cartridges. The air then moves downward between the cartridge filters and towards the settling area, just below the cartridge filters. Once in the settling area, air flow is minimal; therefore, gravity is a deciding influence on the dust, which allows for removal in either the hopper or dust drawer, as configured. A portion of the dust will collect on the surface of the cartridge media as the air passes through the media, through the vertical venturi, into the horizontal clean air duct and to the blower. The dust that collects on the cartridge media will be directed towards the downward air flow by the reverse jet pulse cleaning system. This system is electronically controlled and is usually configured to monitor the differential pressure between the clean and dirty air. When the differential pressure reaches the adjustable set point, a brief burst of compressed air will be released through the venturi and into the core of the cartridge filter to impact the dust away from the filter surface. The dislodged dust is caught by the downward air flow and once again moved towards the settling chamber.
