  • Low pressure pulse jet dust collector
    Patent number: 5421845
    Abstract: The present invention shows a cleaning system for dislodging the collected dust from filter media in a low pressure high capacity gas stream filter. In the preferred embodiment, pressurized gas from an external tank is ducted through a revolving arm which stretches radially across a pie-shaped segment of a tube sheet separating a clean gas plenum from a dirty gas plenum in a bag collection gas filtration system. The ducted gas is intermittently discharged from the rotating arm through multiple orifices into a venturi contained within the openings in the tube sheet as these orifices are above the individual filter elements.

  • Two stage transition input section for dust collectors
    Patent number: 5030261
    Abstract: An improved gas stream inlet construction for industrial dust collectors such as fabric filter type collectors that includes a first transition section in which an incoming high velocity gas stream is reduced in velocity and delivered to a second transition section in a second flow direction substantially perpendicular to the incoming first flow direction and wherein it is further reduced in velocity and is delivered therefrom in a third flow direction substantially perpendicular to both the first and second flow directions.
