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。
Aim To investigate the combat capability of CO vehicles in armored vehicles, a CO gas purifying prototype with a new type of noble metal nano catalyst as the main material was studied. Methods At room temperature, the experiments of single-pass purification, static and dynamic purification in 1 m3 standard and 7 m3 simulated experiments were carried out respectively. Results During the single-pass purification experiment, the prototypes maintained the purification rates of 50% and 40% respectively for the CO gas concentrations below 800 mg / m3 at 1 and 2 m3 / min air volume. In static experiments, the initial concentration of 800 mg / m3, after 3 min 43 s and 20 min, the CO purification rate of the standard and simulation experiments was 90%; in the dynamic experiment, the CO gas entered the chamber at a rate of 6 L / h, and the gas concentration increased The average rate was significantly lower than the control experiment. Conclusions Under natural conditions, the experimental prototype has a clear effect on the purification of CO gas, which breaks through the key technologies of CO gas purification in the chamber under normal temperature conditions and lays the technical foundation for the development of a CO gas purification device suitable for the cabin environment of armored vehicles.
