Abstract
A filtering device for removing particulate matter from a gas stream includes a housing with its interior divided by a horizontal partition into an upper plenum chamber and a lower plenum chamber. Planar panel filters arranged in V-shaped banks are suspended from the horizontal partition in the lower plenum chamber. These banks of panel filters coact with the horizontal partition to form a cleaned gas compartment. The housing also has a dirty gas stream inlet to the lower plenum chamber and a clean gas outlet from the upper plenum chamber. A first venturi is located at the horizontal partition and provides a passage for a gas between the cleaned gas compartment and upper plenum chamber, and a second smaller converging nozzle located in the upper plenum chamber coaxially aligned with and spaced from the first venturi. A high energy cleaning gas emitting nozzle is spaced above the second venturi and aligned to direct a jet of high energy cleaning gas axially into the second converging nozzle.
