MULTISECTIONAL APPARATUS FOR MOLECULAR DISTILLATION Russian patent published in 1997 - IPC

FIELD: chemical engineering. SUBSTANCE: apparatus has rotor drive, upright frame with disposed therein rotor and distillation sections formed by coaxial cylindric surfaces of annular evaporators and condensers. Each section contains pillars with evaporators. Feeding device consists of several fastened to each other discs placed in upper part of frame and a funnel made in the form of annular spaces whereto liquid-supply fittings are led. The funnel is provided with channels to withdraw liquid to evaporator surfaces in each distillation section with hydraulic locks. Molecular distillation sections are separated into vacuum steps with cylindric partitions and corresponding discs, which are sealed between each other with rotating hydraulic locks formed by their annular members. EFFECT: increased capacity of apparatus. 5 cl, 2 dwg
