Description

The invention relates to the separation of suspended particles from gases and can be used in non-ferrous metallurgy plants for the purification of dusty gases.

The purpose of the invention is to increase the reliability of the filter by providing ^{3 a} constant shape of the filter material.

In FIG. 1 schematically shows a pocket filter, section; in FIG. 2 is a view of A u in FIG. 1; in FIG. 3 - filtering section; . FIG. 4 - section B — B in FIG. 3.

Pocket filter for cleaning dusty gases contains a housing 1, input 2 and output 3 nozzles, filter sections 4, made in the form of frames 5, with 15 outer 6 and inner 7 frame rods. Filter material 8 is placed between the rods. The inner frame rods 7 are interconnected by spacer sleeves 9. The filter has a hopper 10. The filter material is attached to the frame rod at points 11 lying on the same axis as the spacer sleeves. The housing has nozzles 12 for supplying air for regeneration.

The filter works as follows. Dusty gas enters through the nozzle and is filtered. The cleaned air exits through the nozzle 3. During regeneration by reverse purging of air, dust is shaken off into the hopper 10 and removed from the filter. Air for regeneration is supplied through the pipe 12.

In this case, the outer and inner rods connected by spacer sleeves do not allow the filter material to inflate and close, increasing the reliability of the filter.
