Description

eleven

The invention relates to devices for cleaning air from dust and fibers with bag filters and can be used to clean gas from pshi and fibers.

The purpose of the invention is to reduce the pressure of the explosion and reduce the area of explosive openings.

The drawing shows the filter section.

The filter consists of a housing 1, a hopper 2, a grill 3 for fastening the sleeves 4, a nozzle for introducing evaporated air 5, a clean air chamber 6 and fuses 7. The accumulated dust and fibers are removed by the pulley shutter 8. The insert 9 inside the hopper 2 takes considerable volume and is a geometric body in the form of truncated cones aligned with bases.

During normal operation of the filter, the air through the pipe 6 is introduced into the hopper 2. Then the air in the grid enters the inside of the sleeve 4. The passage through the tubular fabric clears air from the pierce and fibers and through valves (not shown) enters the clean chamber

air 6, from where it is sucked off by a fan. When regenerating sleeves

(the regeneration system is not shown) and the fibers and fibers from the sleeves 4 fall out into the hopper 2, from where they are discharged by a sluice gate 8.

During the explosion, the suspension in the volume between the wall of the bunker 2 and the insert 9 part of the suspension and combustion products is filtered into the insert volume and the inside space, the remaining mass of gas and gas is dropped through the explosives 7. As a result of a significant decrease in the volume of the explosive suspension due to the device in the bunker 2 inserts 9, the operation of the fuses 7 is facilitated and the pressure of the explosion decreases.

In order to achieve the most efficient operation of the insert 9, the gap between it and the wall of the hopper 2 should be minimized. It is established from the condition of free removal of the filtered ditch or fiber from the filter so that the bunker does not get clogged. The size of the gap is determined for each specific grade based on the experience of the filters.
