Application Study of Electrostatic Precipitation with Earthed Atomizing Discharges
The comparative researches on both positive-and negative-direct current earthed atomizing corona discharges were carried out, and the influence of water flux on corona discharges was also studied. The experimental results showed that the capture efficiency of negative electrostatic precipitation with earthed atomizing discharges is higher than that of the positive one with earthed atomizing discharges. The reason is probably that the ionization region of positive-earthed atomizing discharges was expanded and more aerosol particles passed through the ionization region, which tended to neutralize the charges on the aerosol particles. In contrast, the expanding ionization region was not existent in the negative-earthed atomizing discharges. In addition,under the condition that the wire discharge electrode is 70 mm in length and 1 mm in diameter, the mean diameter of spraying droplets was larger than 80μm when the water flux was more than 3320 μL/min, while it was smaller than 80μm when the water flux was less than 2280 μL/min.
