Description

The invention relates to the purification of gas from dust by filtration and is intended for use in the construction materials industry, chemical, mining and other industries.

An object of the invention is to stabilize filtration quality.

In FIG. 1 shows a bag filter, general view; in FIG. 2 - section aa in FIG. 1; in FIG. 3 - block for accommodating filter bags, one modification; in FIG. 4 - docking ring, general view; in FIG. 5 - same, top view; in FIG. 6 is a diagram of a filter mounting; in FIG. 7-section BB in FIG. 3; in FIG. 8 - cargo, general view; in FIG. 9 is the same side view.

The filter contains a sleeve 1, which is fixed with the lower part to the docking ring element 2 with the flange 3. A compensator 4 made of elastic material is attached to the ring element 2 below. From above

the sleeve 1 is seated on a washer with a hanging loop 5, by which it is connected to the vibrator 6. For communication of the sleeve with the vibrator 6 .po.-, the last is placed on a vertical tubular stand 7, to the upper end part of which the supporting platform 8 is sequentially attached. the shock absorber 9 and the carrier pad 10 with brackets 11 for securing the sleeves 1. The vibrator 6 is placed on the carrier pad 10.

The sleeve unit (single sleeve) is placed in the housing 12 with a roof 13.

The sleeve 1 is mounted on a nozzle 14 cut into the grill 15 above the hopper 16 of the housing 12 and is thus connected to the cavity of the chamber 1-7 of dusty gas into which dusty air is supplied through the pipe 18.

The height of the sleeve 1 from the washer with the hanging loop 5 to the docking ring element 2 contains hanging slings 19 made of a slightly deformable material such as kapron or silk, located with

at the right step, and on top stitched with stitch 20.

On the docking ring element 2, the sleeve 1 is secured with a tie 21 and the compensator with a tie 22. The trapped dirt is removed from the pipe 23.

When passing a stream of dusty air through the inner cavity of the sleeve, a certain amount of dust settles on it, depending on a number of factors, including the structure of the filter material.

In a suspended state and during regeneration, the sleeve sags, the porosity of the material increases and, as a result, the slip and dust emission to the atmosphere increase. . ; ; . ; ; . :. ..; .. Y:

That is why when choosing filter media for the sleeves c. By mechanical regeneration, preference is given to poorly deformed ones:

To use high-performance shaft materials as filters, suspension slings 19 are used.

During operation, dusty air under pressure is fed into the chamber 17 through the pipe 18, from there it enters the cavity of the filter sleeve T. through the nozzles 14 and compensators 4; : V. -. . -. . - / -

Under the influence of air pressure, the sleeves 1 inflate to the full volume, but the expansion of the compensator 4 does not take place due to the mass of the annular element.

If it is necessary to clean the inner cavity of the sleeves 1 from dust after the sensor system has been activated, the vibrator associated with the time relay is switched on.

b, -; ..;:

Compensator .4 allows the sleeve to reciprocate without compromising the integrity of the material of the sleeve.

The sleeve is mounted on the bracket 11 and the pipe 14 so that in the inoperative position (FIG. 3), the compensator 4 is slightly lowered with a power reserve of reciprocating motion.

The hanging slings 19 are taut and the lengths of the slings 19 and the sleeve 1 in the space between the stitches 20 and 21 are equal.

Such a filter is mounted in the following sequence: a sleeve 1, a docking ring element 2 and a compensator 4 with suspension slings 19 temporarily attached to the upper end of the sleeve 1 are suspended on brackets 11 connected to a vibrator 6, then the compensator is fixed on the nozzles 14 cut into the grill 15, the filter is taut.

Thereafter, weights 24 of equal mass are suspended to the free ends of the slings 19 to tension the slings 19, the slings 19 are secured by a stitch 21 along the outer perimeter of the lower part of the filter in the area of its attachment to the annular element 2 and the loads are removed.

The advantage of the proposed technical solution is also shown in the fact that equidistant slings during shaking due to contact interaction with the surface of the sleeve help to improve its cleaning.

Another advantage of the method should be recognized that the equal tension of the slings is possible regardless of the method of securing the upper part of the sleeve (for example, hanging on a loop, pinching between two strips, etc.).

Claims (1)

The claims The method of installation of composite bag filters, in which the sleeves and suspension slings are suspended to the vibrator, the compensator is fixed to the grill and the slings are attached to the mating ring element, and so that, in order to stabilize the quality of filtration , after the compensator is fixed, equal weights are suspended to the free ends of the lines, the lines are fastened with a stitch along the outer perimeter of the lower part of the sleeve in the zone of attachment of the ring element and the loads are removed.
