摘要： A device capable of an efficient desalination using a low-energy-density heat source such as solar energy. The desalination device comprises a solar heat collector (1), an evaporation system (2), a cooling tower (3), a distilled water tank (4), a concentrate brine tank (5), and a vacuum means (6), wherein the vacuum means (6) reduces pressures in evaporation spaces of respective evaporators in the evaporation system (2), steam generated in the preceding evaporator is introduced into the heat-exchanger of an applicable evaporator as a heat source, and generated steam and condensed water are supplied to the heat-exchanger of the next evaporator as a heating source, thereby enabling a multiple-effect use of a plurality of evaporators. A deaeration chamber is provided in the front-most stage of the evaporation system to deaerate a non-condensable gas from raw water supplied to evaporators. A pump (26) for feeding a condensed heat medium to the solar heat collector is provided in a heat medium circulating path.
