摘　　要：为了确保民航在2019-nCoV疫情期间的安全,航空公司增加了关键防疫设备的高效微粒空气过滤器(HEPA)的更换次数,对有疫情的飞机要求在航后立即更换HEPA。但是,飞机维修手册和运输航空公司防疫技术指南中规定的更换程序不足以确保在疫情期间更换设备的安全,在更换过程中存在病毒二次传播的风险。由于这种病毒已经在全球大流行,而一些国家没有限制或无法杜绝生病旅客的旅行,也没有强迫旅客戴口罩,导致HEPA过滤网上病毒数量大增。本文对国内大型航空公司HEPA的更换程序进行了研究,指出了HEPA更换存在的主要问题,并进行了实验验证,提出了切实可行的改进建议。In order to ensure the safety of civil aviation during the 2019-nCoV epidemic,airlines increased the replacement frequency of HEPA,which is the key epidemic prevention equipment.However,the replacement procedures set out in the aircraft maintenance manual and the technical guidelines for epidemic prevention for Transport Airlines are not sufficient to ensure the safety of replacement equipment during an outbreak,and there is a risk of secondary transmission of the virus during the replacement process.The number of viruses on HEPA filters has increased significantly as a result of the global pandemic and the failure of some countries to restrict or eliminate travel by sick travelers or to force travelers to wear face masks.In this paper,the replacement procedure of HEPA is studied,the main problems of HEPA replacement are pointed out,and the experimental verification is carried out.
