COLLECTION EFFICIENCY FOR ELECTROSTATIC PRECIPITATOR ON ROAD TUNNELS

Various electrostatic precipitators have been installed to ensure vehicles' safety in over thirty tunnels in Japan. Recently several electrostatic precipitators have been used to protect environment in the vicinity of the tunnels. Motorcycles' drivers and vehicles' drivers without air-conditioners have much difficulty in breathing inside tunnels in the countries where the regulations are not strict for vehicle emission. The opacity inside tunnels is as much important for the drivers as the concentrations of carbon monoxide and nitric oxides for the people in the U.S.A. and European countries. Deutsch and Matts have defined initial collection efficiency for an electrostatic precipitator. Chang et al. have shown an idea for average collection efficiency for long-term operation but not clearly described the details. Then the authors have measured concentration of dust that an electrostatic precipitator collected from smoky air inside road tunnels with various air velocities. The relation has been clarified between average collection efficiencies and newly developed reentrainment factors, product of dust load and air velocity. The useful equations could be used not only in design of electrostatic precipitators but also in operation of them to obtain appropriate information when they should be cleaned.
