摘　　要：空气取水是一种不受限于常规水源的有效取水方式,能够提升部队在沙漠/干旱地区的给水保障能力。以西北某沙漠地区的实际环境(相对湿度20%)为应用背景,对比分析了雾水收集法、空气冷却法和吸附剂取水法的特性,在低湿度条件下确定采用吸附剂取水法。针对硅胶、沸石或分子筛等传统吸附剂水负荷不高的缺点,研究新型材料MOFs的化学组成和结构特点,结合其吸附能力强和易再生的独特优势,选定MOF-801为吸附剂并设计了一台套筒式MOFs空气取水装置,对取水装置在相对湿度20%的条件下进行计算研究,得出预估产水量,并分析了相关影响因素。Harvesting water from air,without considering conventional water sources,can improve field water supply capability with higher efficiency and self-sustainability,especially for troops in the desert/arid area.Based on the actual environment(relative humidity 20%)in a certain desert area in Northwest China,the characteristics of fog-water collection method,air-cooled method and adsorption method were compared and analyzed,and adsorption method was selected suitable for under low humidity condition.Due to the disadvantages of low water-acquired efficiency using conventional sorbent(such as silica gel,zeolite and molecular sieve),the chemical composition and structure of a new type of MOFs were studied.With excellent performance of absorption and cyclic utilization,MOF-801 was selected as the sorbent to design a sleeve device.The water-acquired capability of the device was calculated,the estimated water yield was obtained,and the related impacting factors were discussed,under the condition of relative humidity 20%.
