【摘要】:主要研究中長期載人航天任務中微重力條件下的膜法水氣分離問題,以中空纖維超濾膜為基礎,通過自行設計的微重力條件下地面試驗系統(tǒng)對膜式水氣分離器的分離性能進行研究,考察阻力降、水/氣體積比和重力等因素對水氣分離器分離性能的影響.研究發(fā)現(xiàn),在一定操作條件下,膜通量隨著阻力降的升高或者水/氣體積比的增大而增大;重力對分離過程無明顯影響.中空纖維超濾膜具有在微重力條件下進行水氣分離的能力,為膜式水氣分離器在載人航天中應用提供支持.
[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.
