【摘要】：研制了熱泵—兩效直接接觸式膜蒸餾試驗(yàn)裝置,對(duì)其性能進(jìn)行了較系統(tǒng)的試驗(yàn)研究。結(jié)果表明,裝置可在常壓下實(shí)現(xiàn)料液的低溫濃縮,且通過(guò)調(diào)節(jié)輔冷器等部件,實(shí)現(xiàn)裝置在設(shè)定工況下穩(wěn)定運(yùn)行;膜組件的膜通量和熱效率隨料液溫度的升高而大幅提高,裝置的造水比受膜組件熱效率和熱泵制熱系數(shù)的共同影響,在66℃時(shí),可達(dá)1.58。
[Abstract]:A heat pump-two-effect direct contact membrane distillation test device was developed and its performance was studied systematically. The results show that the device can realize the low temperature concentration of the feed liquid under normal pressure, and by adjusting the auxiliary chiller and other components, the device can operate stably under the fixed operating conditions, and the membrane flux and thermal efficiency of the membrane assembly increase greatly with the increase of the temperature of the feed liquid. The water ratio of the device is affected by the heat efficiency of the film module and the heat coefficient of the heat pump, and it can reach 1.58 at 66 鈩，
