ABSTRACT:
Apparatus for filtering entrained particulate matter from a gaseous fuel embodies an upstanding housing having a hopper adjacent its lower end for receiving dislodged particulate matter. At least one upstanding, porous tubular filter bag is mounted within the housing. The ends of the filter bag are attached to the housing with its length being greater than the distance between the points of attachment of the ends to the housing. An inlet communicates with one end of the filter bag for introducing a gaseous fluid with particulate matter entrained therein. Particulate matter carried by the gaseous fluid is deposited on the inner surface of the filter bag with cleaned gaseous fluid passing therethrough. An outlet communicates with the housing and discharges the cleaned gaseous fluid. An actuator is operatively connected to the filter bag intermediate its ends for imparting longitudinal reciprocatory movement thereto to relax and extend the upper and lower portions of the bag and dislodge particulate matter therefrom.
