ABSTRACT:
Industrial filter for separating solid particles from a streaming gaseous medium the filter having a filter insert formed from a single band of knitted fabric. The filter insert is provided with a smooth permeable layer of amorphous synthetic polymeric material at least on its inlet inside. Longitudinal and transverse packing sleeves of the filter insert are secured to marginal surfaces of a partition wall by means of a pressure sealing frame. Single filter pockets are inserted in the openings of the partition wall and in place between single filter pockets the filter insert sliding rests upon internal surfaces of the partition wall. During operation a certain amount of separated dust is forced into the gaps between the internal surfaces of partition walls and parts of the filter insert surfaces supported by those internal surfaces. Whereby the accumulated dust layer automatically compensates for the stretching of the needled fabric. The filter insert is provided with internal and external spacers that are swingingly suspended or attached to the partition wall and which maintain required form of the filter insert.
