The invention relates to dust collection, can be used in various fields of application: using abrasive dust gas cleaning.

The purpose of the invention is to reduce the abrasive wear of the housing.

The drawing shows the device, General view.

The filter contains an actuator 1 connected to the rotor 2 with a rotating element of the filter element, the vanes 3, fix the penguin in the upper part. frame of rotor, housing 4, inlet 5, outlet 6, dust bin 7 swirler 8 located in the lower part of the body, cylindrical shell 9, the bottom part of which is formed as a downwardly extending cone S shell is rigidly connected to the body and located between the blades and the body, the upper part of the body is divided by a partition into a clean gas chamber 10 and a gas I gas,

The device works as follows.

Dirty gas through the inlet pipe 5 enters the chamber 11 of the dirty gas, initially falling on the body 8, where it is pre-cleaned by the centrifugal forces of the rotating flow.

Pre-cleaned; gas enters the filter element rotating on the rotor 2s which provides fine gas cleaning. When the filter element rotates, it regenerates reliably, while dust is thrown to the wall.

direct part of the air into the cavity between the shell 9 and the wall of the housing 4, creating airflow along the housing wall from top to bottom, which reduces the impact force of dust particles, OT6pacbiBaeha ix filter element to the housing wall, which reduces its abrasive wear. At the same time, the conditions for the entry of dust into the bunker 7 are improved. During operation, clean air enters the clean gas chamber 10 and exits through the nozzle

7, from which it is periodically removed.

Installing the blades and the shell allows air flow to move along the wall of the housing from top to bottom, reducing the velocity of the impact. Pshvd chastpd, discarded filter element to the walls of the case, thereby preventing abrasive wear of the case and improving the condition of dust in the bunker.

The application of the proposed device allows to increase its service life in comparison with the known 2-4 times, which gives an economic effect.
