Seawater desalination unit has a mechanical vapor condenser working in conjunction with an expansion chamber and condenser

摘要

A seawater desalination plant has a sea water evaporation unit (31), a mechanical vapor compressor and a vapor condenser (39) surrendering desalinated water. The vapor compressor (37) is powered by an absorption powerplant with an expulsion unit (13), an absorption unit (15) and an NH(3 expansion chamber (17). The expansion chamber has a pump (19) and a regulator valve (25) for a solvent (H(2O). The expulsion unit (13) is solar-heated. The solution of water and ammonia pass through the solar collector and then the expulsion unit. The solar collector and expulsion unit form an integrated component. The absorption unit is cooled by water from the sea water evaporator.
