The Electrostatic Precipitation Ventilation Research Of Anyuan Highway Tunnel

Tunnel ventilation is an important technology that restricts long highway tunnels construction. Research in home and abroad indicates that the cost of tunnel ventilation increases with the cube of tunnel length and the highway tunnel running cost is a huge spending after constructed. So the study of highway tunnel ventilation has great society and economy value. The paper based on the controlling ventilation demand of different year of Anyuan highway tunnel, had studied the electrostatic precipitation of Anyuan highway tunnel, by feasibility analysis of using electrostatic precipitation in Anyuan highway tunnel and physical model experiment of the electrostatic precipitation.First ,the paper calculated and analyzed the ventilation demand of different year of Anyuan highway tunnel by using the auto emission standard and the formula provided by specifications for design of ventilation of highway tunnel, it adjusted the auto emission standard provided by research results of tunnel ventilation research center of Chang'an University.The paper recalculated the ventilation demand by the new auto emission standard. The reasonable controlling ventilation demand of different year of Anyuan highway tunnel is gaven. The paper did feasibility analysis of using electrostatic precipitation in Anyuan highway tunnel, it verified the feasibility of using electrostatic precipitation in Anyuan highway tunnel and its economic benefits.The paper had studied the theory and technique of highway tunnel electrostatic precipitation physical model experiment deeply.The paper had researched the air inlet angle of electrostatic precipitation utilized model experiment, suggested the angle should use the minimum angle under tunnel structure and security enabled condition.
