SEA WATER DISTILLING PLANT Russian patent published in 2003 - IPC

FIELD: continuous distilling plants for distillation of sea water, brines and electric conducting solutions; processing of industrial sewage including petroleum products and production of make-up water for boilers of thermal power stations. SUBSTANCE: proposed sea water distilling plant includes hermetic hollow vacuum evaporator at bottom delivery of sea water; cavity of this evaporator is connected at the top with steam condenser and vacuum pump by means of pipe lines ; it also contains distilled water receiver. Novelty of invention consists in form of vacuum evaporator made as vertical tower in form of body of revolution; base of this tower is located below sea level and diameters of any cross section of vertical tower are considerably lesser than height of vertical tower. Walls of vertical tower have holes between plane of base and sea level for delivery of sea water. Upper part of vertical tower is located above sea level. Inner surfaces of towers are provided with spiral fins. Mounted on upper part of vertical tower is vacuum pump which is connected with cavity of upper part by means of branch pipes. Wind motor mounted on upper part of vertical tower is used as drive for vacuum pump. Turbo-expander is used as steam condenser. EFFECT: increased service life; increased productivity; reduced power requirements; enhanced ecological safety; low cost of erection and operation. 11 cl, 1 dwg
