The disadvantage of this inertia-vortex separator is also low degree of cleaning waste gases from fine particles and the impossibility of its use for separation of multicomponent gaseous media.
The technical result of the proposed technical solution is to increase the degree of gas purification from fine particles and expansion of functional possibilities of the separator.
This technical result is achieved due to the fact that in the famous inertial-vortex separator contains the input for flue cleaned air, vortex chamber with a swirl, conical the cone is provided with a pipeline of clean gas discharge, precipitation chamber with a collection of separate phases, according to the invention, swirl and the swirl chamber in the input flue, made in the form of paraboloid confuser, the output of the vortex chamber is equipped with Central cylindrical nozzle, United with paraboloid diffuser, communicating with pyleuborka the pipe, installed coaxially and last connected with precipitation camera, also, between paraboloid cone and tapered cone posted by adjustable circular slot, soamsawali with lateral channel, which serves for removal of gas from the peripheral zone of the separator.
The drawing shows a schematic diagram of the inertial-vortex separator.

The output of the vortex chamber 3 installed Central cylindrical nozzle 4, United with paraboloid diffuser 5, communicating with pyleuborka pipe 6, installed coaxially and last connected with precipitation camera 7. For paraboloid diffuser 5 posted by conical diffuser 8, connected with the pipeline of clean gas discharge 9. Between paraboloid diffuser 5 and conical diffuser 8 posted by adjustable circular slot 10, soamsawali with lateral channel 11, which serves for removal of gas from the peripheral zone of the separator.
Inertial-vortex separator works in the following way.
The gas flow separation dust particles of different sizes serves on input flue 1, made in the form of paraboloid confuser. Then in the paraboloid confuser flow speed and wind swirler 2. In the axial part of the confuser at the output of a zone of low static pressure, which contributes to intensive coagulation of particles. In the Central cylindrical nozzle 4, installed at the exit of the vortex chamber 3, gas flow, which is at the exit of the vortex chamber 3 most expressed gradient properties on the diameter of the flow is stabilized.
When you log in paraboloid diffuser 5 gas flow starts monotonically decrease tangential velocity by law potential flows: V & Phi; r=const, where
V & Phi; - tangential or radial velocity of the gas flow;
r is the radius of the gas stream.
This is necessary for the emergence of the inertial effect of compaction and, consequently, prevent turbulence in the flow in the exit area paraboloid diffuser by increasing the viscosity of the gas. Emerging along the axis of the separator "dust cord" is extracted pyleuborka pipe 6, which is the regulator of the axial acceleration and axial velocity along the axis of the input flue 1, made in the form of paraboloid confuser.
In addition, the inertial effect of compaction and increased viscosity of gases makes the possibility of push on the periphery of the separator of gases such as sulfur dioxide, nitrogen dioxide, carbon dioxide and some other. Through a circular slot 10 and outlet channel 11 these gases are discharged from the peripheral zone of the separator, thus providing regulation boundary layer that you want to save laminar flow patterns.
In conical diffuser 8 is irrevocable for the gas flow to the pipeline of clean gas discharge 9.
