摘　　要：为了更好地改善公路隧道中的空气环境,减少对隧道周边环境的二次污染,需采用比通风技术稀释空气污染物更合理高效的空气净化手段。综合国内外公路隧道空气污染物治理技术的研究进展,结合国内外公路隧道中静电除尘技术的应用实例介绍了静电除尘器(ESP)用于隧道除尘的工作原理和工作过程。在实验模拟和应用实例中,ESP对粉尘颗粒(PM)的去除效率均可达90%以上除尘效率高并且除尘相对比较彻底。同时对ESP的布置方式进行了阐述,结合其它空气净化装置,提出了一种与ESP相配合的隧道空气污染物综合治理方案。实验表明,将隧道空气首先通过ESP除去PM后再对气态空气污染物如一氧化碳(CO)等进行吸附处理,CO等气态污染物的去除效率会大大提高。结合国际上现有的隧道空气净化技术成果,对中国公路隧道空气污染物治理技术的发展趋势进行了展望。This paper presented an overview of technology to upgrade the conventional dilution ventilation for highway tunnel air pollutant removing,surveying the literatures regarding the recent advances,at home and abroad,in air pollution control technology used for highway tunnel,particularly electrostatic dust removing technology,i.e.electrostatic precipitator（ESP） that can remove dust up to 90%.The operation principles of ESP and various methods for removing tunnel pollutants PM,CO and NOx were expounded,and in addition,different installation and arrangement modes of ESP in the tunnel were described.Furthermore,this paper proposed a comprehensive plan for highway tunnel air pollution control by using ESP combined with the other air purification devices,which underlined the role of ESP in removing PM,while gaseous air pollutants such as CO,NOx were better removed by adsorption measures with relative devices,thus the removal efficiency will be greatly improved.Finally,trends in the technical development for highway tunnel air pollution control were prospected.
