Research on Fog-and-Haze Purification Technology for Highways

Abstract

A fog-and-haze purification technology for highways is proposed by analyzing the causes and characteristics of fog and haze and by combining the ground and underground facilities on the highway with a dehumidification and filtration device. A new type of guardrail, which functions as both air spray and suction pipe, is designed. The dehumidification and filtration device, which is connected to these pipes, is installed in the underground space of the highway. Inhaling the fog and haze within a safe driving visual space from the suction pipes as well as dehumidifying and filtering them through the dehumidification and filtration device lead the mist and small particles into the drainage pipeline. The processed dry gas pressurized by a blower with high pressure and temperature is sprayed on the road through the spray pipes. Air purification aims to improve air visibility in the driving area, which can improve the traffic capacity and reduce the accident rate on the highway under hazy and fog weather. This scheme added a solar power system to a new type of slope protection measure combined with electric energy to provide the energy, reduce the cost, and improve the applicability of the technology scheme.
