The invention relates to devices for cleaning air from dust and can be used in any branch of the national economy.

The aim of the invention is to increase the efficiency of dust collection.

FIG. 1 shows a general dust collector; in fig. 2 - dust-like blade, top view.

The dust collector includes a housing 1 in which a concentric louver separator 2, a tangential nozzle 3 for entering the mixture to be cleaned, axial exhaust pipes A and 5 and a dust outlet 6 are located. In the horizontal separator 2 there are convex propeller-shaped blades 7 fixed with fixed upper and lower ends with using, for example, shells 8. The radius of the bulge is 0.75-1.1 radius louver divider.

Dust collector works as follows.

Through the tangential nozzle 3, the dust-air mixture enters the body 1.

When the suspension moves from top to bottom in the housing 1, large dust particles under the action of centrifugal forces are thrown against the wall of the housing. In this way, primary cleaning is carried out. The most contaminated air passes near the wall of the housing. The remaining dust particles are entrained in the air flowing along the louver separator 2, hit the blades 7 of the separator 2, are reflected from them and enter the said contaminated stream that transports them to the dust outlet 6 and removes from the dust collector with 8-10% of air.

The pre-cleaned dust-air stream rotates around the louver separator 2, the tangential velocity component

flow movement is gradually reduced. However, due to the gradual increase in the angle of attack of the propeller-like blades 7, the direction of movement of dust particles after colliding with the blades is getting closer to the radial, which increases the likelihood of them falling into the zone of movement of the contaminated flow, and the air entering the louver separator is forced to turn an increasingly acute angle, which reduces the likelihood of their capture of dust particles in the purified stream

The protrusion of the blades 7 further optimizes the flow of dust and dust around them. Two-sided rigid fastening of the blades 7 by the shells 8 excludes the possibility of their oscillations, eliminating the danger of dust grinding, changes in the living section.

In this case, the absence of oscillations of the blades 7 in combination with their convex shape increases the laminar flow. The combination of all the above features allows a significant increase in the efficiency of the dust collector.
