ABSTRACT:
A method of cleaning a filter element includes directing a jet of pressurized gas from a nozzle onto a filter element, with the jet having a non-round cross-sectional shape that is a same general cross-sectional shape as the opening in a tube sheet holding the filter element. The nozzle has a channel for the pressurized gas that is obstruction-free. A method of designing a nozzle arrangement for directing a jet of pressurized gas onto a filter element includes designing a nozzle arrangement to generate a jet of pressurized gas having a non-round cross-sectional shape that is a same general shape as a non-round shape of an aperture in a tubesheet holding the filter element. The nozzle arrangement includes at least one nozzle, each nozzle has an unobstructed flow channel, and each nozzle is cylindrical in shape and has at least one open slot. A pressurized gas generator includes a compressed air manifold storing pressurized gas, a valve in fluid communication with the manifold, and a nozzle arrangement. The nozzle arrangement includes at least a single nozzle connected to the valve. Each nozzle has either a cylindrical wall or a lobed wall and defines an interior channel. The interior channel is obstruction-free. The wall defines at least one open slot.
