Abstract

The main purpose of this study is to investigate the characteristics of precharge electro-cyclone compared to those of innercharge electro-cyclone, experimentally. Especially, the experiment is executed focusing on the improvement of collection efficiency with the charging types including the experimental parameters such as the discharge electrode shapes, applied voltages and gas inlet velocities. Results show that the overall collection efficiency of precharge electro-cyclone is increased over 20% than that of the innercharge type for the same discharge electrode(ø 4 mm, screw rod) in the inlet velocity of 4 m/s, and applied voltage of 30kV. Moreover, the pressure drop of precharge type becomes 10% lower than that of the innercharge type for the inlet velocity of 12 m/s owing to the disturbance of inner vortex flow by the discharge electrode equipped in the center region of cyclone body.
