Frequency effect on particles collection efficiency in planar DBD-ESP
Résumé
In this paper, the effect of frequency on the performance of a plane-to-plane dielectric barrier discharge electrostatic precipitator (DBD-ESP) is investigated experimentally. The typical characteristic quantities of the filamentary discharge such as the current waveform and the corresponding Q-V curve are presented and discussed. Then, a parametric study is carried out to evaluate the effects of the applied voltage amplitude and frequency on the collection efficiency of submicron particles within the size range from 0.2 to 0.7 um. The main results indicate that the particles penetration increases at low frequencies because of the low charge of particles and at high frequencies because of fast particles oscillation.
