The invention relates to a gas cleaning technique and can be used in various industries to clean process gases from dust while moving them and to extract valuable products from them.

The purpose of the invention is to reduce the hydraulic resistance and increase the efficiency of dust collection.

In FIG. 1 schematically shows a fan-separator, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The fan-separator comprises a housing 1 with a spiral separation chamber 2, an impeller 3, a hopper 4 for collecting the collected dust, longitudinal ribs 5 mounted on the inner wall of the housing 1 in the spiral chamber 2. Dust extraction is provided through channels in the form of Nel holes. 6. The output of the cleaned air is made through the tangential nozzle 7. The width h of the longitudinal ribs 5 is 1 / 3-1 / 2 of the distance P between the impeller and the wall.

Fan torus separator works as follows: HU1M.

The dusty gas is supplied to the impeller 3. Under the action of centrifugal forces, dust particles are pressed to the periphery of the spiral chamber 2 and removed to the hopper 4 through the openings 6. The cleaned gas is discharged through the tangential nozzle 7. The ribs 5 significantly

reduce the intensity of vortex formation at the exit of the impeller 3, as a result of which the hydraulic resistance of the separator fan is reduced and the secondary capture of dust is reduced, which increases the efficiency of dust collection. It was established experimentally that, regardless of the absolute size of the separator, the number of ribs and operating parameters, a positive effect is achieved, which consists in reducing the hydraulic resistance by 3-6% and increasing the separation efficiency by 4-5% with the width of the ribs equal to 1/3 -1/2 distance between impeller and wall.
