METHOD FOR PRODUCING DRINKING WATER FROM SEAWATER AND DEVICE FOR CARRYING OUT SAME

A method for producing drinking water from seawater includes purifying seawater of impurities, separating the flow of water by evaporation into a condensate and brine, compressing the vapour, and carrying out crystallization, with the crystals being separated off by filtration. Evaporation is carried out until the concentration of sodium chloride reaches supersaturation and the sodium chloride crystallizes. The concentrate is then mixed with the condensate. A device for producing drinking water from seawater comprises a unit for filtering solid impurities, a pump, an evaporator, a condenser having a condensate pipe, a vapour compressor connected to the evaporator by an inlet, a crystallizer, and a source of vapour. The evaporator and the condenser have a common heat exchange surface which is provided with a distributing device. The vapour compressor is provided with a jet for feeding water into the vapour. Disposed at an outlet is a heat exchanger.
