目的评价空间站CO2去除系统对舱内大气微量污染物的辅助净化能力及微量污染物对系统去除CO2性能的影响。方法按照空间站微量污染物模型,选取有代表性的11种微量污染物,采用10倍加速条件进行密闭舱注入,在模拟3人CO2代谢量条件下考核CO2去除系统对注入气体及CO2气体的去除效果。结果在3人CO2代谢量条件下,空间站CO2去除系统对大部分微量污染物具有显著去除能力;该试验条件下的舱内微量污染物对CO2气体去除性能无明显影响。结论 CO2去除系统对舱内微量污染物净化可以起到一定的辅助作用。

Objective To evaluate the secondary purification capability of the airborne CO2 removal system on airborne micro-pollutants and the effect of trace pollutants on the removal of CO2 from the system. Methods According to the model of micro-pollutants in space station, 11 representative micro-pollutants were selected and injected in airtight chamber under 10-fold accelerating conditions. The removal of injected gas and CO2 gas by CO2 removal system was evaluated under simulated 3-person CO2 metabolic rate effect. Results Under the conditions of 3-person CO2 metabolism, the removal efficiency of most of the trace pollutants was significantly reduced by the station CO2 removal system. The micro-pollutants in the test chamber had no significant effect on the removal of CO2 gas. Conclusion CO2 removal system can play a supplementary role in the purification of micro-pollutants in the cabin.
