Embodiment Construction

[0031] figure 1 Shows a cross section through a bag filter of known construction. There is a bag bottom 2 with openings 3 in the housing 1, and several corresponding filter bags are arranged or hung in these openings 3. The dust-containing gas A is introduced into the untreated gas side 5 of the bag filter. The filter bag 4 has an upper open end and a lower closed end. The dust-containing gas A flows through the material of the filter bag 4 and enters the clean gas side 6 of the bag filter through the opening 3 in the bottom 2 of the bag. The cleaning gas B is derived accordingly from here. A device 7 for outputting compressed air pulses into the open end of the filter bag 4 is provided in the clean gas side 6 of the bag filter in order to clean the filter bag. These devices 7 for outputting compressed air pulses can be formed, for example, by a correspondingly configured power injection pipe 8 having an opening 9 above each filter bag 4 and a compressed air source 10 connec...

Abstract

The invention relates to a bag filter for cleaning dust-laden gases A, comprising a housing (1), which is divided into a filtered-gas side (6) and a unfiltered-gas side (5) by a bag bottom (2) having openings (3), in which housing (1) several filter bags (4) having a flat cross-section are arranged in the openings (3) of the bag bottom (2). According to the invention, each support basket (12) is connected at the end associated with the open end of the respective filter bag (4) to an injector nozzle (15) for conducting and accelerating the dedusting compressed-air pulses, which injector nozzle (15) protrudes at least partially into the openings (3) of the bag bottom (2), and sealing elements (16) are arranged on the outside of the injector nozzle (15) at the height of the bag bottom (3) in order to form a defined gap ([delta]d) for a defined compression of the filter bag (4) between the sealing elements (16) and the jacket surface (17) of the opening (3) in the bag bottom (2) and thus to independently seal the filter bag (4) with respect to the opening (3) of the bag bottom (2).

Description

Technical field [0001] The present invention relates to a bag filter for cleaning dust-containing gas. The bag filter has a housing, and the housing is divided into a clean gas side and an untreated gas side by a bag bottom with an opening. The housing is provided with a plurality of filter bags with a flat cross-section, the filter bags respectively have a closed end and an open end in the bottom opening of the bag, the filter bag can be applied with dust-containing gas from the outside and clean gas through the opening The bag filter has a device for outputting compressed air pulses into the open end of the filter bag to clean the filter bag, wherein a cage is respectively provided in the filter bag. [0002] The invention also relates to a nozzle for a filter bag of such a bag filter, the nozzle at least partially protruding into an opening in the bottom of the bag. Background technique [0003] Bag filters are used to separate solid matter such as chips, dust or the like from ...
