摘　　要：目的针对潜艇舱内低浓度异味气体影响艇员作战能力问题,用一种由改性化学吸附材料和低温等离子体技术的组合净化装置进行实验测试。方法分别对组合净化装置进行480 h连续净化实验和30 m^(3)模拟实验舱内的净化实验。结果480 h连续净化实验,净化装置对初始浓度分别为0.4~1.0、0.14~0.35和3.5~7.0 mg/m^(3)的甲硫醇、硫化氢和氨气的净化率均达到90%以上;模拟实验舱内自然环境条件下,净化装置对甲硫醇、硫化氢和氨气净化率均达到90%以上。结论组合净化装置对低浓度异味气体的净化效果明显,为研制适用于潜艇舱室较高湿度环境的异味气体净化装置奠定了技术基础。Objective To carry out an experimental test on a combined purification device using modified chemical adsorption materials and low temperature plasma technology.Methods A 480-hour continuous purification experiment and a purification experiment in the simulated chamber were conducted respectively.Results In the 480-hour continuous purification experiment,the purification efficiency of the combined purification device for methanethiol,hydrogen sulfide and ammonia at the initial concentrations of 0.4-1.0,0.14-0.35 and 3.5-7.0 mg/m^(3)exceeded 90%.In the purification experiment in the 30 cubic meter simulated chamber,the purification efficiency for methanethiol,hydrogen sulfide and ammonia under natural environments also surpassed 90%.Conclusion The combined purification device has obvious purification effect on low concentration odor gases,which can contribute to the development of odor gas purification devices for high humidity environments in submarine cabins.
