A pulse cleaning filter system has a housing with an inlet side and an outlet side separated by a planar tubesheet. The housing includes multiple tubesheet openings forming multiple rows. Multiple cylindrical filter cartridges have an open end sealed around one of the tubesheet openings and a closed end at the inlet side of the housing. A filter cleaning system includes a compressed gas header extending perpendicular to a normal of the tubesheet, multiple compressed gas outlet stub pipes extending from the header, right angle pulse valves connecting each of the stub pipes to a pulse manifold pipe including a first straight portion, a ninety degree bend at the outlet side of the housing, and a second straight portion at the outlet side of the housing. A gas pulse nozzle has a main injection axis directed along the central axis of the filter cartridge. |
