VACUUM-DISTILLING APPARATUS Russian patent published in 1995 - IPC

FIELD: chemical and petrochemical industries. SUBSTANCE: source liquid in the apparatus is pumped by delivery system 6 and bypass valve into one of cavities 4 and 5 of evaporator 1 where it is accelerated by means of a torus 2 provided with hydrodynamic resistances 3. This reduces the pressure of liquid. As soon as pressure drops below the saturation limit at the given temperature, it starts boiling. Steam is taken away by torus 2 into the steam collection system 8 and 9 and liquid is drained into the used liquid collection system 10 and 11. EFFECT: improved design. 1 dwg
