摘要

摘要: 建立了考虑浓差极化现象的微分方程数学模型,并用正交配置法求解,对中空纤维膜机载制氮装置(OBIGGS)进行了分析,并对部分状态点的计算结果进行了实验验证.结果表明:富氮气体(NEA)中氧气的质量分数随着进气温度的升高而降低,在达到最小值后又呈上升趋势;在进气与排气压力差保持不变的情况下,随着中空纤维膜排气压力的下降,中空纤维膜的富氮气体质量流量逐渐增加;随着中空纤维膜丝长度的增加,丝内气体的压降和富氮气体质量流量均有所增加;中空纤维膜空气分离制得的富氮气体质量流量越大,则所需进气的质量流量越大,且富氮气体氧气质量分数越高.

Abstract: Differential equations mathematical model was built up, and solved by orthogonal collocation method to study the onboard inert gas generation system (OBIGGS), some of the results were verified by experiments. Results show that, the nitrogen-enriched air (NEA) oxygen mass fraction decreases with increasing of feed air temperature, then increases when the NEA oxygen mass fraction to a minimum value; in condition of differential pressure between the feed air and exhaust gas is constant,the NEA mass flow rate of hollow fiber membrane increases gradually with decreasing of exhaust gas pressure; pressure drop of retentate gas and the NEA mass flow rate both increase with increasing of hollow fiber membrane length,mass flow rate of feed air and the NEA oxygen mass fraction are influenced by the NEA mass flow rate obtained from hollow fiber membrane air separation,when the NEA mass flow rate is larger, the mass flow rate of feed air and the NEA oxygen mass fraction of the both increase.
