Abstract
A mechanical vapor compression desalination system was set up, of which the designed capacity is 2 m3·d-1, and the evaporator temperature is 95 ℃. The system is composed of evaporator-condenser, compressor and preheaters. The performance of the components and the effects of the parameters on the energy consumption were analyzed experimentally and theoretically. The results indicate that the experimental system works well when the operating temperature is in the range from 89 ℃ to 97 ℃, and that the production rate increases with the evaporator temperature. When the salinity reduces from 40% to 20%, the production rate increases by about 72%. The least seawater separation work of the system is 594 kJ·kg-1.
