| 摘 要： | 基于大气中水的吸附与解吸循环，设计出吸附式空气取水装置，并对其进行了实验研究。该装置主要由太阳能集热器、吸附床和冷凝器等组成。晚上吸附剂吸附空气中的水，白天由太阳能提供热量进行解吸。实验制备了硅胶（SC）-CaCl2、SC-LiCl、活性炭纤维毡（ACF）-CaCl2、ACF-LiCl 4种新型复合吸附剂，并对其进行了实验测试。结果表明：由ACF制备的复合吸附剂性能比由SC制备的复合吸附剂性能要好；ACF-LiCl的吸附与解吸性能最好，在吸附床出口温度为90℃时，解吸6 h的产水率是0.412 kg水·（kg吸附剂）-1。

| Abstract: | Based on the sorption and desorption cycle to realize fresh water production from the atmosphere, the sorption air-to-water device is designed and experimental research on this device is carried out.The device is mainly composed of solar collector, sorbent bed and condenser.In night the water in the air is sorbed by the sorbents and in the daytime the composite sorbents desorb the water vapor using solar energy.Four kinds of novel composite sorbents are prepared and several tests on this device are carried out, which are SC (type C silica-gel)-CaCl2, SC-LiCl, ACF (active carbon felt)-CaCl2 and ACF-LiCl.The experimental results show that:the performance of composite sorbents whose host material is ACF is better than sorbents whose host material is SC.The sorption and desorption performance of ACF-LiCl is the best, when the outlet temperature of sorbent bed is 90℃,the freshwater yield is 0.412 kg water·(kg sorbent)-1 after six hours desorption. |
