  • Patent number: 7094265
    Abstract: A cleaning device for a bundle of tubular filter elements designed with one end open, preferably of an industrial dust filter, is proposed. Injectors for delivery of a pulse-like compressed-air jet into the filter elements are arranged above the openings of the filter elements. The compressed-air supply of the injectors, controlled via valves, takes place via a number of nozzle tubes extending at right angles to the injectors, and a number of injectors are connected in a row to each nozzle tube. Only some of the nozzle tubes are connected directly to valves and these nozzle tubes extend to a deflection, from which at least one further nozzle tube closed at its end extends in the opposite direction. The deflection is preferably at the same time a branching from which two nozzle tubes extend, which are located on the two sides of the centrally arranged nozzle tube.
