    The invention relates to devices for separating two more component fluids, more precisely to those devices in which the withdrawal of the concentrated phase is achieved by settling it under the action of aerodynamic and hydrodynamic forces.
    Known device for separating two or more component fluids, containing several sequentially coaxially located at some distance from one another and decreasing in diameter rings, interacting with the flow of fluid moving inside them and oriented along the direction of its movement, and a container for receiving the concentrated phase, installed on the side of the last smaller ring.
    Despite its simplicity, compactness and the absence of moving parts, the device provides a low degree of cleaning, has a relatively high resistance and is subject to intense abrasive wear.
    The purpose of the invention is to increase the degree of separation of media, reduce aerohydraulic resistance and increase wear resistance.
    The proposed device for separating two or more component fluids contains several sequentially coaxially located at a certain distance from one another and decreasing in diameter rings, interacting with the flow of fluid moving inside them and oriented along the direction of its movement. and a container for receiving the concentrated phase, installed on the side of the last smaller ring. Each ring usually has a sharpened inner edge, and the distance between adjacent rings is chosen such that the rings do not overlap one another.
    Preferably, the distances between adjacent rings are equal, with the inner side of each ring being curved.
    It is advisable to make the cone formed by a set of rings have a ratio of the inlet diameter to its length of at least 1: 5,
    The drawing shows the proposed device, a longitudinal section.
    The device has a plurality of rings 1 of gradually decreasing diameter.
    1804340 -AZ located coaxially. The rings 1 are rigidly attached to the longitudinal guides 2 at a certain distance I from one another to obtain annular channels 3 between them and form an imaginary cone 4. inside which a multicomponent fluid moves.
    The cone 4, assembled from rings 1 and guides 2, is mounted inside a cylindrical casing 5 with connecting flanges 6 and 7. To the cone 4 on the side of its smaller ring 1 in diameter, a branch pipe 8 is connected for removing the fluid, which goes into the container 9 for receiving the concentrated phase, for example, dust contained in the gas stream.
    Each ring 1 is oriented in the direction of the flow of the fluid in the cone 4, for which the inner side of the rings 1 is given a profiled shape, for example, curved.
    Each ring 1 is made with a sharpened inner edge 10, and the distance I between the rings 1 is chosen such that they do not overlap each other. Usually this distance is commensurate with the width of the ring 1.
    Preferably, when the rings 1 are placed at an equal distance I from one another, and the cone 4 formed by them and the guides 2 has a ratio of the inlet diameter to its length of at least 1: 5.
    A flow stall is organized at the edges 10. as a result, in the annular channels 3 between adjacent rings 1 a continuous flow of toroidal vortices arises, which are located along the generatrix along the imaginary cone. The layer of toroidal vortices creates an elastic medium for displacing the concentrated phase into the central region of the axial flow of the fluid and thereby protects the rings 1 from abrasive wear.
    At the same time, the absence of mutual overlap of rings 1 creates conditions for the stable existence of a flow of toroidal vortices.
    The concentrated phase separated from the fluid flow is gradually located along its axis and is removed through the nozzle 8 into the container 9. The purified fluid, as it passes through the cone 4, is removed through the annular channels 3 and the casing 5.
    PRI me R 1. A device with an inlet ring diameter of 200 mm and an outlet ring diameter of 20 mm with a cone length of 2000 mm is used. The rings are made of an identical profile with a pitch of 10 mm and a ring thickness of 5 mm. The dust and gas flow rate is 30 m / s. dust concentration up to 10000 mg / m 3 , fractional composition of dust,%: up to 50 μm 50, less than 1 μm 5, from 50 to 1 μm the rest.
    The average statistical degree of purification is 95-97% when operating one stage of the device.
    Example 2. A device is used with an inlet ring diameter of 100 mm and an outlet ring diameter of 10 mm with a cone length of 1000 mm. The feed rate of the dust and gas flow is 30 m / s, the dust concentration is up to 10,000 mg / m 3 , the fractional composition of the dust is the same as in example 1,
    The average statistical degree of purification during the operation of one stage is 90-92%, with the operation of two successive stages 94-96%.
    Devices existing today for cleaning a dust and gas flow with the same fractional composition of the solid phase provide a purification degree of no more than 70-75% with a fraction size mainly up to 50 microns.
    With the help of the proposed device, it is possible to widely regulate the cleaning performance by arranging the devices in packages, for example, from 2 to 100 pieces or more, and to increase the cleaning degree by sequentially installing the devices in several stages.
    Equal distances between adjacent rings allow for uniform velocities of fluid flows outgoing between these rings.
