Description

The invention relates to the textile industry, in particular to the field of dusty air cleaning using a cyclone.

Known two-stage cyclones with an inlet pipe parallel to the axis of the cyclone, and the tantational exit. In such cyclones, air is cleaned only from fine dust.

In order to more effectively clean the air from dust and lint, the inlet pipe is mounted along the axis of the proposed cyclone, and its lower opening is located in the conical part of the second stage of the cyclone.

The drawing shows the scheme of the proposed cyclone.

It consists of an outer casing /, which is the first stage of a cyclone, inside which a centrifugal cyclone is placed, comprising a case 2 having openings 3, an axial inlet 4 and a tangential outlet 5 nozzles.

Works cyclone as follows.

The dusty air at a high speed enters the first cyclone stage through an axial nozzle having a tapered conical opening at the end, at the exit of which the dust of centrifugal force is thrown to the walls of the housing.

The air entering the cyclone creates in the conical part of the body / increased pressure, due to which air with dust pressed to the walls rises and encounters holes 3 in the body 2 of the second stage of the cyclone. The purified air through the tangential nozzle 5 exits the cyclone, and the dust, which has lost its speed, under the action of ejection formed by the incoming air flow, is lowered into the lower part of the body 2 and mixed with the main flow.

But in the dusty air there is fluff

having passed along the axial nozzle 4, continues to move along the axis of the cyclone and is removed from it through the outlet hole in the lower part of housing 1. The downward movement of the flux along the axis is ensured by the fact that

air with dust to the walls of housing 1, as if compressed the flow of air entering along the axis of the cyclone, thereby increasing the flow rate in which there is fluff, not allowing the latter to remain in the cyclone. So

thus, in a cyclone, dusty air is effectively cleaned from dust and lint.

Subject invention

A two-stage cyclone with an inlet nozzle parallel to the axis of the cyclone and a tangential outlet, characterized in that, in order to more effectively clean air from dust and lint, the inlet nozzle is mounted along the axis of the cyclone, and its opening is located in the conical part of the second stage of the cyclone.
