装甲车辆舱室内一氧化碳气体净化实验研究

Purification of carbon monoxide in armored vehicle cabins

目的针对舱内CO气体影响装甲车辆乘员作战能力问题,对一种以新型贵金属纳米催化剂为主要材料的CO气体净化样机进行实验研究。方法室温条件下,分别对样机进行单程净化实验、1 m3标准实验舱和7 m3模拟实验舱内的静态与动态净化实验。结果单程净化实验时,在1和2 m3/min的风量下,样机对800 mg/m3以下浓度的CO气体分别保持了50%和40%以上的净化率;静态实验时,初始浓度800 mg/m3条件下,经过3 min 43 s和20 min,样机对标准实验舱和模拟实验舱内的CO净化率达到90%;动态实验时,CO气体以6 L/h的速率入舱,气体浓度上升平均速率明显低于对照实验。结论在自然环境条件下,实验样机对CO气体净化效果明显,突破了常温条件下舱室内CO气体净化的关键技术,为研制适用于装甲车辆舱室环境的CO气体净化装置奠定了技术基础。

Objective To study a purification prototype with a noble metal nano catalyst as the main material in order to improve the combat capability of the crew of armored vehides.Methods At natural temperature, the single way purification experiment, static and dynamic purification experiments were carried out in the 1 m3 and the 7 m3 cabins. Results In the single way purification experiment, the prototype kept the purification rate above 40%and 50%when the CO concentration was below 800 mg/m3 and the air flow rate was 1 and 2 m3/min.During static experiments, the CO purification rate was 90% at the initial concentration of 800 mg/m3 and after 3′43″and 20′.During the dynamic experiment, the average elevation rate of the gas concentration was significantly lower than that of the control experiment. Conclusion In a natural environment, the prototype can effectively purify CO gas.Key technology of CO gas purification has been made available that can be used to develop CO gas purification devices in armored vehicles.
