静电除尘装置（ESP）在我国公路隧道中应用的可行性

机动车辆在公路隧道中产生的各种空气污染物质严重影响着行车视距和驾乘人员的身心健康,国内外专家提出了各种提高公路隧道内空气质量的处理方案。通过调研分析公路隧道用静电除尘装置的原理、效果以及在世界各地的应用情况,探讨了静电除尘装置应用于我国公路隧道的可行性。研究发现,与其他废气处理技术相比较,采用静电除尘技术治理隧道废气在世界公路隧道中得到了广泛应用,技术成熟稳定,处理效果优良,具有极高的社会效益和经济效益。采用静电除尘加射流风机的纵向通风系统是一种既经济又环保的通风方案,也是公路隧道通风技术的发展方向。随着公路隧道的发展、静电除尘技术的成熟和人们对空气质量要求的提高,在我国的公路隧道中安装静电除尘装置将是保护环境的需要,更是人民健康的需要。

The Feasibility of Applying Electrostatic Precipitators to Road Tunnels in China

Vehicle emissions inside road tunnels seriously affect driver＇s sight distance and people＇s health.Domestic and foreign experts have proposed various kinds of treatments to improve the air quality inside road tunnels.By analyzing the principle and effect of electrostatic precipitators,and their applications in the world,this article discusses the feasibility of applying them to road tunnels in China.The results show that： comparing with other treatments,electrostatic precipitators have been widely used in road tunnels of the world,with mature technology,superior effects,and bringing in great social and economic benefits.It is found that the combination of electrostatic precipitators and longitudinal ventilation system will be an economical and environment-friendly ventilation solution,as well as the future direction of road tunnels＇ development.With the evolution of road tunnels,maturity of electrostatic precipitators and people＇s ever rising requirements for air quality,installing ESP in China＇s road tunnels will not only be environment demanded but also people＇s health required.
