FIELD: machine engineering.
SUBSTANCE: device for desalination of sea water includes a body located inside and fixed on the frame structure with a suction valve, and a valve for discharging concentrate by a plunger pump, the movement of vertically arranged plunger working on reverse osmosis principle and containing a coiled flexible material that is twisted in shape of cylindrical pipe which is a reverse osmosis membrane, to the lower position passing beyond the limits of the body under the action of its weight, and lifting to the upper position is performed by a flexible coupling, one end of the lifting device is connected to the lower end of the plunger, and at the other end connected to a source of unidirectional intermittent motion in the form of sea wave energy converter.
EFFECT: simplified design and improved reliability.
