| Abstract: | A new type of electrostatic precipitator(ESP) which named dipolar charging ESP was developed.The collection principles were analyzed,mainly including ionic wind,electric field force and electric agglomeration.The ionic wind velocity was measured by PIV technology.V-I characteristics and collection performance of dipolar charging ESP were tested.The experimental results have shown that the ionic wind velocity is about 2m/s,and the current and the collection efficiency of dipolar charging ESP for collecting fine particulates are obviously higher than that of the conventional ESP. |
