Abstract: 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.
