摘要/Abstract

摘要： 为提升吸附式空气取水吸附床吸附性能,对套管式吸附床吸附性能的影响因素(风机功率和传质通道直径大小)进行实验分析。利用称重法分别测量不同因素影响下吸附床吸附量随时间变化情况。结果表明,为满足吸附床吸附要求,需对吸附床进行风机送风;吸附床吸附量随着风机功率增加而增加,最大提升约14.5%;随着传质通道直径加大而变大,最低提升约39.66%;相比于提升风机功率,提升传质通道直径能更好地提高吸附量,效果为提升风机功率的3倍以上。

Abstract: To improve the adsorption performance of adsorption bed for water vapor sorption from air, the related influencing factors (fan power and diameter of mass transfer channel) were investigated experimentally in this paper.The change of water sorption capacity with time under different influencing factors was measured via weighing method, respectively.The results showed that fan should be added to sorption bed to meet the requirement of sorption needs.The adsorption capacity of sorption bed rised about 14.5% as the fan power increases and it improved almost 39.66% with the increase of mass transfer channel diameter as well.Moreover, the size of mass transfer channel diameter had a bigger influence on sorption capacity compared to fan power, and the effect was more than 3 times of the fan power.
