Description

one

The invention relates to devices for gas cleaning and dust collection and can be used in various fields of industry, for example, for cleaning gases from steelmaking furnaces of engineering plants, in the energy sector, ferrous metallurgy,

The purpose of the invention is to reduce operating costs and improve the reliability of the filter.

The drawing shows schematically the proposed bag filter, the cross-section.

The filter consists of a sectioned housing 1, in which the filter sleeves 2 are crushed, collectors 3-5 of purge, cleaned and dusty gas, respectively, bunkers 6 with inlet pipes 7.

dusty gas and gas distribution partitions 8.

The principle of operation of fsh is as follows.

The dusty gas from the collector 5 goes through the nozzles 7 to the hopper 6, where by means of gas distribution walls 8 it is evenly distributed through the filtering sleeves 2. The gas cleaned in the filter sleeves is collected in the collector 4 and removed from the filter. : The regeneration of the filter bags is carried out by sectional blowback under the action of the pressure differential between the collectors 3 and 5 of the purge gas and the dusty gas. The sweep gas entering the dust gas collector 5 is distributed in sections operating in a filtering mode.
