Purification of carbon monoxide in armored vehicle cabins / 军事医学

ABSTRACT

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.
