Abstract
Electrostatic precipitators are used in decontaminating polluted gases in expressway tunnels in order to improve both driver safety and the environment around the tunnels. A conventional electrostatic precipitator has high collection efficiency but is still needed to improve collection efficiency for nano-particles smaller than 0.1 μm. The experiments carried out in this study have focused on improving nano-particle collection efficiency without using additional energy. The experimental electrostatic precipitator was a two-stage type consisting of a pre-charger and a collector. The collector had a parallel-plates configuration, including a grounded electrode and a high voltage electrode. A hole-punched stainless plate was used as the high voltage electrode in order to improve nano-particle collection efficiency. The collection efficiency as a function of the particle diameter was studied. As a result, the nano-particle collection efficiency on the ESP with the hole-punched high voltage electrode was significantly improved. In the case of certain number of hole, the nano-particle collection efficiency increases with increasing the punched hole diameter. In the case of the constant of aperture rate, the nano-particle collection efficiency increases with decreasing the punched hole diameter. This effect is probably due to increasing the electric field intensity near the hole edges of the hole punched electrode.
