摘要
研制了热泵—两效直接接触式膜蒸馏试验装置,对其性能进行了较系统的试验研究。结果表明,装置可在常压下实现料液的低温浓缩,且通过调节辅冷器等部件,实现装置在设定工况下稳定运行;膜组件的膜通量和热效率随料液温度的升高而大幅提高,装置的造水比受膜组件热效率和热泵制热系数的共同影响,在66℃时,可达1.58。
The experimenlal heat pump two-effect direct contact membrane distillation system was developed, and its performance was alsostudicd systematically. The results showed that the device could concentrate thermal-sensible liquid under low temperature at atmospheric pressure and run under setting conditions by regulating the auxiliary cooler. The membrane flux and thermal efficiency could be greatly increased with the increasing of material temperature. Un der the influence of the combined effect of the membrane component thermal efficiency and the heat pump coefficient, the gained output ratio could achieve 1,58 at 66 ℃.
