Abstract
Factors which forms a flow field in an electrostatic precipitator (ESP) is a shape of ESP, a gas flow velocity and an ionic wind. Ionic wind is a flow that occurs ions generated by corona discharge collide with air molecules. About the influence on the particles of the ion wind, it is not clarified enough. It is important for the clarification of a particle collecting process, and improvement in particle collecting efficiency to clarify the interaction in ESP including an ion wind. The new hole-type ESP was developed to minimize re-entrainment. In this study, it analyzed the particle behavior of hole-type ESP by using PIV (particle image velocimetry) analysis. This paper reports a PIV analysis result about an ion wind and the particle movement velocity.
