多孔LiOH的吸收性能研究
|
摘要
CO_2浓度对人体生理健康有着重要的影响。为了更好的控制密闭环境中CO_2浓度,对多孔LiOH的吸收性能进行研究。实验研究表明,在一定范围的循环风量下,提高系统的循环风量和采用气体复合循环的方式能够提高多孔LiOH的利用率。多孔LiOH利用率的提高,能更好地保障航天员进行舱外活动。
The CO_2 concentration has important effect on human physiological health. In this paper, the absorption performance of porous LiOH was studied in order to better control the CO_2 concentration in the airtight environment. The experiment research showed that, under a range of circulating air volume, increasing the circulation air volume of the system and using the method of gas combined cycle can improve the utilization rate of porous LiOH.The improvement of porous LiOH utilization rate can better safeguard the astronaut extravehicular activity.
