METHOD AND DEVICE FOR SEPARATION OF LIQUID INTO FRACTIONS WITH VARIOUS DENSITY Russian patent published in 2009 - IPC B01D17/04 

FIELD: technological processes.

SUBSTANCE: invention is related to separation of liquids into fractions of various density, and may be used in oil production, food and other industries, and also in the field of environment protection for treatment of waste waters and water reservoirs in case of emergency oil and fat fractions and oil products spillage. Flow of initial fluid is supplied through filling pocket and laminating partitions into vertical separating reservoir of separation plant. In upper part of reservoir a vacuum underpressure is previously pulled by means of air displacement through reservoir filling with heavy fraction liquid and its further drain. At the same time light fraction due to pulled vacuum is intensely sucked to upper level of mixture, where it is collected above float chamber of collector and is drain into collecting tank. Heavy fraction is removed through drain tap from flow path.

EFFECT: provision of low power inputs and independence of device on energy sources.
