- Abstract:
- A multi-effect distillation technology for seawater desalination driven by tidal energy and low grade energy is presented.In the system, tidal energy is utilized to supply power instead of coventional electric pumps during the operation, resulting in the decrease of dependence on steady electric power supply and a reduction in the running costs.According to the technological principle, a testing unit is designed and built.The effects of the feed seawater temperature and the heat source temperature on the unit performance are tested and analyzed.The experimental results show that the fresh water output is 27 kg/h when the heating water temperature is 65 ℃ and the absolute pressure is 25 kPa.The experimental and theoretical analysis results indicate that the appropriate heating water temperature is a key factor in ensuring the steady operation of the system.
