| 摘 要： | 提出了一种利用低品位热能和潮汐能驱动的多效蒸馏海水淡化技术,其特点是利用潮汐能代替传统电泵为系统运行提供动力,从而减少了系统运行对稳定电力供应的依赖,降低造水成本.根据该技术的原理,设计搭建了一套试验系统,测试并分析了给海水温度和加热水温度对该系统运行性能的影响.试验结果表明,当加热水温度为65℃,系统绝对压力为25kPa时,系统的淡水产量为27kg/h.通过试验和理论分析发现,选择合适的加热水温度是维持系统稳定运行的关键因素.

| 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. |
