Bag filter for cleaning dust-laden gases and injector nozzle for such a bag filter

A bag filter assembly for cleaning dust-laden gases, comprising:

• a housing;
• a bag bottom disposed to divide said housing into a filtered-gas side and an unfiltered-gas side, said bag bottom having a plurality of openings formed therein;
• a plurality of filter bags disposed in said openings, said filter bags having a flat cross-section, a closed end and an open end, wherein the dust-laden gases are to be applied to said filter bags from outside and cleaned gases are to discharged through said open ends;
• elements for outputting compressed-air pulses into said open ends of said filter bags for dedusting said filter bags;
• a respective support basket disposed in each said filter bag;
• an injector nozzle connected to each support basket at an end thereof associated with said open end of the respective said filter bag, said injector nozzle being configured for conducting and accelerating the dedusting compressed-air pulses, and said injector nozzle protruding at least partially into a respective said opening of said bag bottom;
• and
• sealing elements disposed on an outside of said injector nozzle at a level of said bag bottom to form a defined gap for a defined compression of said filter bag between said sealing elements and a jacket surface of said opening in said bag bottom and to thereby independently seal said filter bag with respect to said opening of said bag bottom.
