DEVICE FOR FRACTION SEPARATION OF LIQUID MIXTURES Russian patent published in 1995 - IPC

FIELD: separating materials. SUBSTANCE: device has evaporator, system for supplying liquid mixture to be separated, and system for removing vapor and vat residue (non-evaporated residue). The evaporator is made up as a hollow housing. Two double-shell tori are mounted inside the housing space. The tori moves by way of flexible ties passing through centers of the tori. The space between the torus shells is separated by the ring baffle to define two spaces filled with gases under different pressures. The space of the internal torus is filled with liquid. The systems of evaporator and systems for supplying liquid, removing vapor and vat residue are connected with the evaporator space at the housing faces. EFFECT: enhanced efficiency. 1 dwg
