FIELD: separation of liquid mixtures into components, particularly, separation of high-boiling and thermostable liquids; applicable in food, chemical and petrochemical industries. SUBSTANCE: device has evacuated body 1 in the form of stepped vertical cylinder with central round blind hole 2 and with coaxial dead cavity which are communicated through curved channels 4. Dead cavity is separated into sectors by partitions integral with device body. Vapor accumulation system is made in the form of plates 7 similar in size and directed over tangent to channel arc. Plates are made integral with body cylinder wall 8 most spaced from device axis. Holes 9 are made between two neighboring plates. Annular compartments 10 isolated from one another are formed inside wall 8 and located over cylinder height, and communicated with vapor accumulation system through hole 9, and with purified liquid accumulation system through valves 11. Purified liquid accumulated system presents hollow cylindrical container located round body 1 and consisting of isolated from one another annular vessels 12 located over body height. Initial mixture supply system is made so that body 1 is connected through packing glands 14 with expanding tank 15 for accumulation of initial mixture. EFFECT: increased productivity and service life of device, reduced power consumption, improved quality of fractionation by separation of multicomponent mixtures into close-cut fractions. 3 dwg
