Description

one

The invention relates to the purification of gases and dust removal and can be used in various sectors of the industry for trapping solid impurities from gases. Bag filters are known for cleaning g-basics containing (filter fixed in the filtering filter grids, loads are placed on the lower Kotmax of the filter, made in the form of hollow bodies, and regenerating nozzles 13.

The disadvantage of such a filter is the difficulty of removing the fluff from the lower ends of the sleeves, the difficulty of tensioning the latter with two-sided supply of dusty gases, and the difficulty of mounting loads.

The aim of the invention is to prevent the deposition of dust in the lower ends of the filter sleeves, their reliable tension during the two-sided supply of dusty gas and ease of installation, as well as the effective regeneration of the filter sleeves.

This goal is achieved by the fact that the proposed filter is equipped with baskets placed in loads with pivoting stops, with the upper ends of the baskets attached to the filter sleeves. In addition, the weights are attached to the lower ends of the filter sleeves at a distance of 0.7-1.5 diameters of the sleeve from the bottom of the grate, and the nozzles are located in the interlevel space at a distance of 1-1.5 diameters of the sleeve above and below upper gratings.

FIG. 1 shows a bag filter,

general form; in fig. 2 is a sectional view of Ag-A of FIG. one; in fig. 3 - node I of FIG. Ij in FIG. 4 times a b b FIG. 3

The filter consists of a housing 1, an inlet 2 and an outlet 3 for gas and a bunker 4 for collecting dust, filtering hands BOB 5, the upper ends are fixed in the upper 6 hose grille, and the lower ends are dried through the holes in the lower 7 grill and tensioned with weights 8 , made in the form of hollow bodies, such as cylinders. Inside loads 8, there are baskets Q, made of rods and strips, the top of which are attached to the sleeves, and

the lower bars of the baskets 9 are connected to the support lugs 10 on which they are supported from the loads 8. The loads 8 are freely suspended from the lower tops of the sleeves 5 at a distance from the lower grid 7, equal to 0.7 to 1.5 diameters of the sleeves, and the circular pipe 11 located in the sleeve between. a space at a distance of from 1 to 1.5 diameters of the sleeves above the bottom 7 and below the top 6 grids, with the nozzles 12 facing each other along the axis of the sleeves.

The filter works as follows. The compressed gas enters the housing 1 through the inlet nozzles 2, passes from above and below through the filter bags into the cleaned one and is removed from the housing through. inlet pipe 3, Solids are removed from the inner surfaces of the sleeves using regenerating nozzles disintegrated in the interstitial space. For this, purified gas is supplied to the nozzles 12.

or air that pulses from the contamination with pulses during an automatic mechanism (not shown on the drawing line). In addition, for additional hangings on the lower ends of the sleeves, the weights mounted on the baskets are used. During the regeneration period, the sleeves are compressed, and the loads are raised accordingly. Upon termination of the pulsed blow, the cargo is lowered and the sleeves additionally shaken. The remote on the dust of the sleeves falls into the hopper and is removed from the hull.

When mounting and replacing the filter sleeves, the stops turn inward and the weights are removed freely.

Claims (2)

1. A bag filter for cleaning gases comprising a casing fixed in lattices (} 1 sleeves, on the bottom plates of which there are loads made in water of hollow bodies and regenerating nozzles, characterized in that, in order to prevent dust from depositing at the lower ends of the filter sleeves, their reliable tension during the two-sided supply of dusty gas and ease of installation, the filter is equipped with baskets with pivoting stops placed in the cargo, with the upper ends of the baskets attached to filler sleeves. 2. The filter according to claim 1, which is based on the fact that, in order to increase the efficiency of the regeneration of the filing sleeves, the loads are attached to the shock ends of the filter sleeves at a distance of 0.7-1.5 diameters the sleeves are from the lower scraper, and the nozzles are razpapod & s in the fuzzy spacer at a distance equal to 5 of the hose diameter above the lower and below the upper slats.
