A Study of the Dust Removal Potential by the Cathode of an Electrostatic Precipitator

A preliminary analysis and an experimental study were performed of the various functions of the cathode of an electrostatic precipitator. They include: corona discharge, the establishment of a high field intensity, dust collection, the reduction of secondary dust-emission loss, the weakening and elimination of counter-corona harmful effects as well as the prevention of low voltage and high current-related unfavorable operations. It is suggested that cathode structure improvement can lead to a reduction of the cathode secondary dust-emission loss and the enhancement of the cathode dust-collection effectiveness as well as to a suppression of counter-corona. Meanwhile, it is also conducive to a stable operation of the electrostatic precipitator under the condition of a high voltage and relatively low current, thus achieving the aim of high dust-removal efficiency. The resolution of the above-mentioned issues can provide helpful reference data for the design, modification and operation of electrostatic precipitators.
