高速公路雾、霾净化技术研究

Research of Fog and Haze Purification Technology for Expressway

对雾、霾产生原因及特点进行了分析,将高速公路地上、地下设施与除湿、过滤装置相结合,研究了高速公路雾、霾净化技术。净化方案提出了新型防护栏设计,使其兼备空气喷、吸气导管作用,地下空间设置除雾、过滤装置并与上部管道相连接。利用吸气导管吸入安全行车视距空间内的空气,通过除湿、过滤装置对道路上空雾、霾进行净化处理,将雾水及微小颗粒引入排水管线,处理后的干燥气体经过鼓风机加压后由喷气导管喷向道路上空以净化空气,以满足高速公路雾、霾天气下的能见度要求,提高道路通行能力,降低交通事故率。在新型边坡防护措施中增加了太阳能发电和储能装置,降低了造价,提高了适用性。

The causes and characteristics of fog and haze are analyzed, combining the ground and underground facilities on expressway with dehumidification and filtration devices,the fog and haze purification technology for expressway is researched. In the purification scheme,a new type of guardrail is designed. The guardrail acts the function as both air spray pipe and air suction pipe, in the underground space of expressway,dehumidification and filtration devices are installed to connect with these pipes,inhaling the air within safely driving visual space from the suction pipes,and dehumidifying and filtering the fog and haze though dehumidification and filtration devices,the mist and small particles are leaded into the drainage pipeline,the processed dry gas pressurized by blower with high pressure and temperature is sprayed on the road through the spray pipes for air purification to meet the requirements of air visibility,improve traffic capacity and reduce accident rate on expressway in hazy and fog weather. In the new type of slope protection measure,a solar power generation and energy storage system is added to reduce the cost and improve the applicability of the technic scheme.
