A MULTICOMPONENT MIXTURE SEPARATION DEVICE AND A NOZZLE CHANNEL FOR THE SAME

摘要

The invention relates to cryogenic engineering, namely, to a device for separation of a multicomponent mixture, as well as to a nozzle channel (2) for the said device, and may be used for liquefying gases, treating them or for extracting one or several target components from a multicomponent mixture flow. The device for separation comprises a prechamber (1) with a mixture flow swirler (10) arranged therein, a nozzle channel (2) for separation that is connected to the prechamber, and a unit (3) for collection of drops and/or solid particles. The separation channel (2), which comprises a convergent segment (5), a divergent segment (6), and a cylindrical segment (7) arranged therebetween, is characterized in that the cylindrical segment (7) has a generating line length greater than 0.1D, where D is a diameter of the cylindrical segment, and the divergent segment (6) is made with an annular ledge (8) having the shape of a step which plane is located perpendicularly to the channel axis. The technical effect is a lowered pulsation level in a flow and, consequently, increased separation efficiency and decreased losses of mixture flow total pressure.
