空气净化技术在超长水下公路隧道通风中的应用研究

Application of Air Purification Technology in Extra-long Underwater Highway Tunnel Ventilation System

空气净化技术是解决公路隧道机动车废气污染的一种重要手段,但目前国内相关应用案例和研究成果较少,无法指导超长水下公路隧道通风设计。本文结合国内某超长水下公路隧道案例,提出了3种可行的净化通风方案;并通过理论计算得到了不同交通工况下隧道内典型污染物沿隧道长度的浓度分布情况,分析了不同净化通风方案的污染物控制效果。通过经济性、环保性、可实施性等多方面比选,确定了适合应用在超长水下公路隧道的空气净化通风方案。

Air purification technology is an important means to solve the motor vehicle pollution in underwater highway tunnel.However,there are few relevant application cases and research results in China at present,which cannot guide the ventilation design of ultra-long underwater highway tunnel.This paper put forward three feasible ventilation purification schemes based on an ultra-long underwater highway tunnel.Through theoretical analysis,the concentration distributions of typical pollutants along the tunnel under different traffic conditions were obtained,and the effects of different purification ventilation schemes were analyzed.And then,the optimal purification ventilation scheme was suggested for the ultra-long underwater highway tunnel by comparison of economy,environmental protection and practicability.
