The invention relates to the purification of gases and liquids from suspended particles due to the forces generated in a rotating flow and can be used in the chemical, metallurgical and other industries.

Known cyclone, containing a cylindrical body, tangential inlet and axial outlet nozzles. Bunker-dust collector

The lack of a cyclone is low dust collection efficiency 5 which is caused by a disordered flow structure in its flow part,

A device is known that contains a tangential inlet channel with a screw guide attached to it, an axial outlet collection chamber, a central exhaust pipe with a conical socket, a conical reflector mounted along the axis of the separator and a shell located between the pipe and the C21 casing,

The disadvantage of the device is the low efficiency of dust collection. This is due to the absence in the separation space of elements that contribute to the long-term residence of particles in a swirling flow and the subsequent deposition of fine fractions in compact filters.

The purpose of the invention is to increase the separation efficiency.

The goal is achieved by the fact that in a vortex chamber containing a casing, a tangential inlet channel with a screw guide attached to it, an axial outlet nozzle, a collection chamber, a central chimney with a conical socket, a conical reflector mounted along the axis of the chamber, and a shell located between the pipe and the casing, the shell is provided with elastic elements of the filter material installed in its lower part around the perimeter, the guide is made multiple-fold so that its peripheral edges are located lower it is internal and the upper part of the shell is attached to the peripheral edges of its last turn, located at a distance from the walls of the casing.

FIG. 1 shows a vortex precipitation chamber, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The chamber contains a housing 1, an inlet channel 2 with a guide 3, an axial outlet nozzle 4, a collection chamber 5 with a discharge opening 6, a exhaust pipe 7 with a conical bell 8, a conical reflector 9, a shell 10. To the bottom of the shell are attached at the perimeter, elastic filter elements. 11. In the napr of the bridges 3, steps 12 are made.

The device works as follows.

The polluted flux enters the housing through the channel 2, twists and spirals down along the spiral direction 3. The particles of contamination due to centrifugal forces move from the axis of the chamber and through the notches 12 are withdrawn from the separation zone, gradually moving through the gap between the casing 1 and the shell 10 into the collection chamber 5. The cleaned stream passes through a layer of elastic filter elements made, for example, in the form of strips, is filtered and flows through the pipe 4 into the stretched pipe 7.

During operation, the filter elements 11 are drawn into the inlet of the shell 10 and form a dense layer that is regenerated by pulsations of the stream being cleaned.

The proposed design solution allows to increase the separation efficiency due to additional particle trapping in filter elements, ordered flow movement along guides, the location of the edges of which facilitates the rapid removal of particles from the separation zone.
