基于城市道路设施的雾、霾净化技术方案研究

Technology Scheme of Fog and Haze Purification Based on City Road Facilities

分析雾和霾的气象特征,结合冷、热气流运动规律,利用城市道路附属设施,研究雾和霾净化技术方案。雾净化方案提出新型路缘石、新型中央及两侧带护栏和新型路灯设计,在满足自身原有功能的基础上增加吸气、排气孔道和太阳能发电装置,利用吸气孔道吸入道路行车安全视距范围内的雾气,通过地下除雾装置处理后的干燥气体经过喷气导管喷向道路上空,聚集的雾水及微尘经地下排水管道排出,达到净化空气的目的。霾净化技术方案提出在分隔带、路面板及人行道地下内埋设铜线圈,利用通电产生的弱静电场吸附空气中的悬浮颗粒物,实现道路行车视距范围内的局部除霾效果。利用城市电网辅助太阳能储电系统的模式为系统提供能源,以降低造价和提高适用性。

The characteristics of the fog and haze were analyzed and the fog and haze purification technology scheme was also researched,combining with the movement regularity of cold and hot air and using subsidiary facilities of city road. The fog purification technology scheme proposed a new design of the curb,the guardrail at central and both sides as well as the street lamp,in which the air spray,suction pipe and solar power generation device were added on the base of their original functions; the fog was inhaled by the suction pipes within safely driving visual space; the air was dehumidified and purified through dehumidification device installed in the underground space of city road,the mist and small particles were leaded into the drainage pipeline and the processed dry gas with high pressure was sprayed on the city road through the spray pipes; so the purpose of air purification for improving air visibility in driving area was achieved. The haze purification technology scheme proposed that copper coils were set up under the separator,pavement and sidewalk,and the suspended particulate matter in air was absorbed by weak electrostatic fields of copper coils when they were electrified,which realized the purpose of eliminating haze partly in driving area. The energy of the system used the city power network and assisted solar electricity storage system,which reduced costs and improved applicability.
