A Theoretical Analysis of Multi-Effect Distillation System Driven by Tidal Energy and Low Grade Energy
A multi-effect distillation unit for seawater desalination utilizing tidal energy and Low Grade Energy has been developed, in which tidal energy is utilized to supply power for water supply, drainage and vacuum extraction instead of pumps powered by electricity. So the cost can be greatly reduced. The system is based on multi-effect evaporation-condensation processes and operates under vacuum condition, so low grade energy (such as solar energy, residual heat) can be used with a high thermal efficiency. Hydrodynamic and thermal analysis is carded out for the water supply and drainage system driven by tidal energy. The operating mechanism of the vacuum extraction system driven by tidal energy is presented. A parametric study of the behavior of the solar desalination unit has been performed.
