浮空器氦气纯化方法应用研究

Research on application of aerostat helium purification method

在浮空器使用过程中,外界空气的混入将导致其内部氦气纯度降低,从而影响到浮空器正常使用。文中通过对常用气体分离方法的分析研究,提出了以高压低温冷凝和低温吸附相结合的方式作为浮空器氦气提纯方式的思路,并详细给出了实现工艺流程和控制方案。换热计算结果表明:该纯化方法液氮消耗量小、氦气提纯成本低。

Aerostat＇s working capability is influenced when atmosphere mixed into its envelope and debased the inner helium purity.Through analysis of general gas separation methods,this paper presented a kind of high-pressure condensation and adsorption method as aerostat＇s helium purification way,detailed working flow and control scheme were also presented.Heat exchange calculation shows that,this method costs low liquid nitrogen and low expense.
