An installation (10) for desalinating sea water is disclosed. Power is supplied to the installation (10) by pumping water, via sea-swell activated pumps (14) from a circulating tank (12) to a turbine (16) which drives an electrical generator (18). The generated electricity is used to drive pumps (24, 26), a refrigeration unit (28), an extractor fan (30) and a centrifuge (32) via electric motors (34, 36 and 38) respectively. A sea-swell activated pump (42) pumps sea water sequentially through a vessel (44), a heat exchanger (46), refrigeration unit (28) and an ice-formation vacuum chamber (48) to reduce the temperature of the sea water to form a mixture of ice crystals and concentrated brine. A rotating centrifuge (32) and an inclined vibrating conveyor (40) combine to separate the ice crystals from the concentrated brine. The ice crystals are fed via pipe (58) to the vessel (44) and the resultant desalinated water is pumped to a storage tank (62) via pump (24). |
