Description

I

The invention relates to devices for separating the transported material from the air flow of pneumatic conveying installations and can be used in various technical techniques.

Known cyclone, comprising a housing with a conical describe and tangential inlet and outlet nozzles located one above the other ij.

The disadvantage of this device is its large aerodynamic resistance due to repeated turning of the dust-gas flow, and the considerable height of its body.

The purpose of the invention is to reduce the aerodynamic drag and height of the apparatus,

For this, the separator is provided with a partition mounted between sxoimbn.s and the outlet nozzles, and a screw guide; ,, adjacent to the wall of the housing and ekachivayuscheys the bottom wall of the inlet.

The partition-continuation of the upper wall of the inlet nozzle may 6i.iri, made in the form of a louvered grille.

The drawing shows the npett irtraeMoe R device, general view.

The inertial-centrifugal separator contains a cylindrical body 1 with a tangey-inlet inlet 2, has an upper 3 and lower 4 walls and is located at an angle to the vertical axis of the OLE body and improves the twisting conditions of the gas to be purified. The outlet pipe 5 is attached to the housing 1 also tangentially and is located directly 13 above the inlet pipe. The inlet and outlet nozzles can be located in opposite directions or at an angle to the circumferential one, and at the point of attachment of the inlet nozzle to the casing they are separated by a partition 6, which can be made in the form of a louvre grille. The partition 6 is a continuation of the upper wall 3 of the inlet 2, the continuation of the separation part 6 is a screw guide 7,

adjacent to the wall of the housing, occupying a part of its free cross section and ending at the bottom wall 4 of the nozzle. The housing has a tapered OHvime 8 and a cover 9. The partition 6 and the screw guide 7 can be interconnected by a cover 9.

Works an impromptu healer as follows,

The flow of the mixture at high speed flows through the inlet pipe 2 under the flap to the body 1 of the separator. Inside the casing, the flow acquires a rotating motion. Particles that are part of the solid phase and have greater inertia than the gas phase of the flow, fly through the space connecting the inlet 2 and outlet 5 nozzle, not having time to get into the outlet nozzle 5,

A small part of the gas phase (air can flow directly from the inlet nozzle 2 to the outlet nozzle 5. Moving further the flow of the mixture falls beneath the luzy partition 6. Here too, part of the air penetrates through the louver into the outlet nozzle the main flow of the mixture continues to move inside housing 1. So As a result, partial separation of the air mixture is already occurring in the widened space and in the louvre grating zone. In addition, in these zones (especially under the louvre grating), there is an intense motion of solid particles in The area of the body is not TohbKO as a result of centrifugal force, but also as a result of the influence of aerodynamic force directed radially towards the outlet nozzle 5. Aerodynamic force arises as a result of air moving into the outlet nozzle 5 by the action of the centrifugal and aerodynamic forces, they are thrown against the wall of the housing 1. Continuing to move in a spiral in the near-wall region, solid particles fall under the screw guide 7,

They are pressed to the wall by centrifugal force and bounded above the screw guide; they cannot be thrown into the outlet nozzle 5, but moving in a spiral.

go out from under the helical guide 7 and get into the zone of action of the inlet nozzle 2. Here they are again affected by the air flow directed downward at an angle to the horizon, causing them to spiral down the inner surface of the conical bottom 8, from where it leads to the outside. The air flow, having made one hollow ascending coil inside the hull, does not

by striking considerable resistance on its way and freed from solid particles, it enters the outlet nozzle 5. Moving in space at the inlet nozzle, the air flow carries with it

part of the incoming air. Passing over the louvre grille, it creates some vacuum over it, which causes air to suck through the blinds. All this causes the occurrence of aerodynamic force, accelerating the

radial run of solid particles to the wall of the separator.

Thanks to the proposed implementation of the inertial centrifugal separator manages to reduce its aerodynamic drag and height,
