DESALINATION APPARATUS USING NANOFLUID AS HEAT CARRIER FROM SOLAR COLLECTOR

摘要

Desalination apparatus (10) is provided for removing impurities from an impure liquid, and comprises a vacuum chamber (14) including a vaporization compartment (70) and a condensation compartment (72), and a solar heater (12) for raising the temperature of the impure liquid. The condensation compartment (72) includes a cooling element (78) for causing condensation of vapour and the solar heater (12) includes a solar-energy collector (26) for absorbing solar radiation and a heat exchanger (28) for transferring heat to the impure liquid. The solar-energy collector (26) and the heat exchanger (28) are fluidly interconnected in a heating circuit containing a heating fluid which includes a suspension of nanoparticles in a liquid. A system and method are also provided.
