This invention relates to the purification of gas from dust and can be used in various industries.

The aim of the invention is to increase the efficiency of filtering regeneration of their elements due to the simultaneous turning of the basket and filtering of their elements around their axes, driving them, increasing the centrifugal forces, and reducing energy consumption.

FIG. 1 shows a filter diagram, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 is a section BB in FIG. 3; in fig. 5 — node II in FIG. one; in fig. b - section BB in FIG. five; in fig. 7 shows the node 111 in FIG. one; in fig. 8 - section GG in FIG. 7

The filter includes a housing 1 with an inlet 2 and an outlet 3 with nozzles for air, a rotary basket 4 with bag filter elements 5 and an attachment b for their rotation. The basket 4 is connected to the nozzle 3 by a conical casing 7. The nozzle 3 rests on the cover 8 of the housing 1 on the bearing 9 provided with an elastic gasket 10, for example, of rubber, which simultaneously serves as a sealant. The filter elements 5 are fixed with their axes 11 (Fig. 4) on the basket 4, which is equipped with radial beams 12 and 13, and the elements 5 are mounted on the basket with bearings 14. The axis 11 of each filter element 5 is equipped with an impeller 15 in the lower part (Fig. 5 ) placed at the installation level of the inlet nozzle 2 placed tangentially to the housing 1. The lower end of the central axis 16 of the basket 4 is provided with radially fixed fingers 17 resting on an annular agitator 18 with inclined teeth (Fig. 7). The angle of inclination of the tooth is not more than 30 °. The hivatel 18 is attached to the body on the radial beams 19 (Fig. 8). The liner 10 allows the basket 4 to move in the vertical direction to the height of the tooth of the agitator 18. In the upper part of the housing 1, a clamp 20 of the basket 4 is installed, made, for example, in the form of a screw. The lower part of the housing 1 is provided with a nozzle 21 for removing dust. The upper part of the filter elements is provided with a sealing cuff 22 of elastic material (Fig. 3)

The filter works as follows.

The flow of dusty air enters through the inlet tangential nozzle 2, penetrates through the wall of the filter elements 5 into the inside of the sleeves, and the cleaned one goes through the nozzle 3 to the consumer or into the atmosphere.

When the filter resistance increases to the calculated value due to the accumulation of dust on the outer part of the filter elements 5, they are regenerated. To do this, continuing filtering, the basket 4 is removed from fixation, unscrewing the screw.

A stream of dusty air rushing through the nozzle 2 tangentially to the body provides intensive rotation of the impellers 15, especially those that are closest to the nozzle 2, while the basket 4 rotates.

On its axis 11 and axis 16 of the basket 4, considerable centrifugal forces are generated, ensuring the dust bursts from the surface of the filter element, which falls into the lower part of the housing 1.

Since the directions of rotation of the filter elements 5 and the basket 4 are the same, the centrifugal forces add up and increase substantially.

Due to the fact that in the zone of the inlet pipe the flow rate increases. Air flow in this place increases

0 rotation of the filter elements around its axis, which additionally increases the centrifugal force and provides high-quality regeneration.

Rotation of the axis 16 with basket 4

5 causes the fingers 17 to slide along the inclined plane of the teeth of the agitator 18 (Figs. 7 and 8). The fingers 17 reach the top of the tooth and fall into the cavities between the teeth, which causes a vertical oscillation of the axis 16 and, respectively, of the ZIEN 4 and intensive insertion of the filtering elements 5, which ensures dust from the pores of the web. Falling lumps of dust in the lower part of the housing 1 are removed through the pipe 21.

The filter can work both in case of regular regeneration of filter elements (with very dusty air) and with periodic regeneration. In the latter case, after regeneration of the filter elements, the basket 4 should be locked from turning by the latch 20.

0 The supply of the axis of each filter element in the lower part with an impeller placed at the installation level of the input tangential nozzle allows the energy of the contaminated gas to be used for

from rotation of the basket as a whole and each filter element separately, which excludes the use of an additional piece of equipment of an electric motor with a gearbox and a control unit and, consequently, electricity

0 his work. In addition, this allows simultaneously with the rotation of the basket alternately and individually spin each filter element, since the air flow rate increases in the area of the nozzle. This increases the speed of rotation of the filter element around its axis and additionally increases the centrifugal force that separates the dust particles from the web.

Supplying the lower end of the central axis of the basket with radial fingers supported on a ring-shaped toothed rider with inclined teeth fixed to the housing allows the basket with filter elements to rotate simultaneously with the use of centrifugal forces to regenerate the filter elements while rotating the filter basket. significantly increases the intensity of regeneration.

The technical and economic efficiency of the proposed filter consists in increasing the efficiency of regeneration of filter elements due to simultaneous rotation of the basket and filter elements around their axes, which leads to an increase in centrifugal forces separating dust from the surface of filter elements. This allows up to 40-60% increase of the filter cycle between regenerations of filter elements, and the use of a stirrer further increases the specified filter cycle to 15-20%. Energy use dusty gas for

basket drive and filter sleeves, as well as for shaking the latter, reduces energy consumption by 1.2-1.3 times.
