【摘要】：主要研究中长期载人航天任务中微重力条件下的膜法水气分离问题,以中空纤维超滤膜为基础,通过自行设计的微重力条件下地面试验系统对膜式水气分离器的分离性能进行研究,考察阻力降、水/气体积比和重力等因素对水气分离器分离性能的影响.研究发现,在一定操作条件下,膜通量随着阻力降的升高或者水/气体积比的增大而增大;重力对分离过程无明显影响.中空纤维超滤膜具有在微重力条件下进行水气分离的能力,为膜式水气分离器在载人航天中应用提供支持.
[Abstract]:This paper mainly studies the separation of water and gas by membrane method under microgravity condition in long-term manned spaceflight missions, which is based on hollow fiber ultrafiltration membrane. The separation performance of membrane water gas separator was studied by the ground test system under microgravity condition. The effects of resistance drop, water / gas volume ratio and gravity on the separation performance of water gas separator were investigated. Under certain operating conditions, the membrane flux increases with the increase of resistance drop or the increase of water / gas volume ratio, and gravity has no obvious effect on the separation process. The hollow fiber ultrafiltration membrane has the ability to separate water and gas under microgravity. It provides support for the application of membrane water gas separator in manned spaceflight.
