AGGREGATE FOR MEMBRANE DISTILLATION Russian patent published in 1995 - IPC

FIELD: liquid dissolved component extraction. SUBSTANCE: aggregate has: chambers for cooling liquid circulation, walls of which are made of waterproof heat-conducting material; chambers for hot solution circulation, walls of which are hydrophobic microporous membranes; chambers for distillate collection, located between chambers for cooling liquid circulation and for hot solution circulation. One of walls of chambers for distillate collection is heat conducting wall of a neighboring chamber, in which cooling liquid is circulating, and another wall of chambers for distillate collection is hydrophobic microporous membrane of a neighboring chamber, in which hot solution is circulating. Chambers for cooling liquid circulation and chambers for hot solution circulation are provided with longitudinal partitions, dividing them for two half-cells, connected by a canal. In the case canal for cooling liquid feeding and removing, half-cells, connecting them canals of all chambers, in which cooling liquid is circulating, are in series communicating with each other, forming united canal; canal of hot solution feeding and removing, half-cells, connecting them canals of all chambers, in which hot solution is circulating, also are in series connected to each other, forming united canal; Longitudinal partitions, dividing chambers, in which hot solution is circulating, for two half-cells, as a version, are provided with transverse partitions, located on their planes in staggered order. The design of aggregate allows to create good conditions for heat-exchange of heat carriers, facilitating membrane process and as a result of it, to increase aggregate productivity at least by 30 EFFECT: aggregate for membrane distillation is used for liquid dissolved component extraction. 2 cl, 9 dwg
