摘要：

搭建设计了太阳能自动跟踪膜蒸馏系统 ,自制配比苦咸水 ,在不同膜蒸馏方式下观测膜蒸馏对离子的截留效果 ,研究了流体温度、流量、真空度以及并联膜组件对真空膜蒸馏过程性能的影响.其次 ,在不同跟踪方式下对集热器换热性能进行测试 ,并研究了太阳辐照量对光伏组件的影响.最后 ,对系统性能随太阳辐照度的变化进行了测试分析.结果表明 ,膜蒸馏截留率均保持在 97%以上;膜通量随温度、真空度的增大而增大 ,流量对膜通量影响较小;并联膜组件产水量是单支膜组件产水量的 2倍.真空集热器与保温水箱的最佳循环流量 200L/h;自动跟踪方式集热量较大;光伏组件的输出功率与太阳辐照度成正比.采用真空式膜蒸馏在自动跟踪方式下 ,当太阳能集热器面积为 1.82m2 ,光伏板面积为 6.5 m2 时 ,最大膜通量为 7.70kg/ (m2 ·h),膜蒸馏产水量最大为 462.27g/h.

The outdoor solar automatic tracking membrane distillation system was built and designed. Self-made brackish water with a ratio of brackish water, observed the ion retention effect of the water produced by membrane distillation under different membrane distillation methods, and studied the fluid temperature, flow rate, vacuum degree, and the effect of parallel membrane modules on the performance of vacuum membrane distillation process. Secondly, the heat transfer performance of the collector was tested under different tracking methods, and the effect of solar irradiation on photovoltaic modules was studied. Finally, a test analysis of the system performance with the change of solar irradiance is carried out. The results show that the rejection rate of the brackish water membrane distillation product water is maintained above 97%; the membrane flux increases with the increase of temperature and vacuum, and the flow rate has little effect on the membrane flux; the water output of parallel membrane modules is twice that of a single membrane module. The optimal circulation flow of the vacuum collector and the heat preservation water tank is 200 L/h; the automatic tracking method collects more heat; the output power of the photovoltaic module is proportional to the solar irradiance. Outdoor vacuum membrane distillation is used in the automatic tracking mode. When the solar collector area is 1.82m2 and the photovoltaic panel area is 6.5m2, the maximum membrane flux is 7.70 kg/(m2·h), and the maximum membrane distillation water production is 462.27g/h.
