DEVICE FOR PERFORMING DIAPHRAGM PROCESSES BY EVAPORATION THROUGH DIAPHRAGM

FIELD: devices for performing diaphragm processes by evaporation through diaphragms; separation of liquid media in any industry. SUBSTANCE: diaphragm apparatus includes housing where corrugated partitions secured in S-shaped strut are located which are coiled in spiral; housing includes also two spiral chambers for counter flow of mixture to be separated and hot heat-transfer agent. Diaphragms made from hollow fiber are located in first chamber; open ends of these diaphragms enter the permeate receiving chamber. Heated mixture which is to be separated flows in spiral chamber becoming additionally heated over its entire length by hot heat-transfer agent and is separated on diaphragm. Easily penetrable component is directed to permeate receiver via inner passage of hollow fiber and is discharged. Concentrate is removed from spiral chamber through respective branch pipe. Construction of apparatus makes it possible to simultaneously separate several components from mixture due to use of different diaphragms in one module and several permeate receivers for separate components. EFFECT: enhanced efficiency. 4 cl, 6 dwg
