DEVICE FOR FLOW SEPARATION OF MULTI-COMPONENT MEDIUM Russian patent published in 2023 - IPC F25J3/00 B01D53/24 

FIELD: cryogenic engineering.

SUBSTANCE: invention relates to devices for separating a multicomponent medium. The branch pipe for supplying the flow of a multicomponent medium is located tangentially with respect to the conical screw, which is made of a three-start screw with a variable winding pitch of the blades, the pitch of which decreases from the inlet to the outlet. A channel is made in the screw, the cavity of which is connected with the cavity of the condensate collection tank and opens into the internal cavity of the cylindrical section. The confuser section of the channel is made at least two-stage. The inner surface of the first stage is equidistant to the outer surface of the conical screw. The second stage is made in the form of a transition with rounded sections of cylindrical surfaces of a larger diameter into cylindrical surfaces of a smaller diameter. The channel of smaller diameter is divided into at least two cylindrical sections of different diameters. The droplet and/or solid particle selection unit contains a profiled sleeve having at least two outer cylindrical surfaces of different diameters. The inner cavity of the bushing contains at least sequentially located cylindrical, diffuser and cylindrical sections and is connected to the outlet channel, made in the form of a hollow body, mainly of rotation, containing internal diffuser and cylindrical sections and installed in the hollow body. On the outer surface of the profiled sleeve, a droplet stopper is made, located in front of the inlet to the condensate drain pipe.

EFFECT: increased efficiency of flow swirl and reduced flow pulsations at supersonic speeds.
