本发明公开了一种基于化学循环空气分离技术的机载制氧‑制氮系统,将空气通入分离系统中,利用部分化学材料(吸氧剂)可以在一定压力和温度条件下吸收氧气,并在不同的条件下将氧气释放出来的特点,将空气中的氧气和氮气分离。得到纯度较高的氧气用于座舱乘客呼吸或做其它用;富氮气体通入燃油箱进行冲洗惰化,达到防火防爆的目的。本发明具有分离效率高、能耗低、可连续工作等优点。

    The invention discloses an on-board oxygen generation-nitrogen generation system based on a chemical circulating air separation technology. Air is introduced into a separation system; by using characteristics that a partial chemical material (an oxygen absorbent) can absorb oxygen under a condition of a certain pressure and temperature and can release the oxygen under different conditions, the oxygen and nitrogen in the air are separated. The obtained oxygen with higher purity is used for cabin passengers to breathe or other purposes; nitrogen-enriched air is introduced into a fuel tank to flush and inert the fuel tank so as to achieve a fire and explosion protection purpose. The on-board oxygen generation-nitrogen generation system based on the chemical circulating air separation technology has the advantages that the separation efficiency is high, the energy consumption is low, the system can continuously work and so on.
