摘要
介绍3种方法收集空气中的水资源:①制冷结露法,将湿空气温度降到露点以下,使其中的水蒸气结露而获得液态水;②吸附法,含湿空气流过吸附剂,其中的水蒸气被吸附,然后加热吸附剂使水分脱附,从而得到淡水;③聚雾取水法,将雾中小水滴分离出来的取水方法。为提高空气取水技术的取水率还需探讨含湿空气在甲虫背部的凝结析水机理和开发高效吸附剂。
Three methods of water extraction from air （WEA）, i.e. water extraction from air by refrigeration （WEAR）, water extraction from air by adsorption （WEAA） and fog water collection （FWC）, were illustrated in this paper. WEAR is to obtain the liquid water by the dew of vapor through refrigeration of the humid air. WEAA is to obtain the fresh water by heating the adsorbent, which adsorbs the vapor of humid air. FWC is to obtain water from the little drips in fog. The coagulation and water extraction mechanisms of humid air on the back of beetle and the development of adsorbents with high adsorption efficiency are to be further studied for improving the water extraction efficiency.
