In this paper, the physical model of anti-corona phenomenon was established, the theoretical model of anti-corona suppression powered by an electrostatic precipitator (ESP) pulse has been obtained. A dust collecting method was suggested in which a gas has ionized by an electrostatic field to adsorb dust particles to an electrode. The relationship between pulse frequency, amplitude pulse width and dust removal efficiency were tested. Research results showed that the physical model of anti-corona phenomenon could reflect the process of corona generation. The circuit scheme of superimposing high-voltage pulse based on direct current high voltage can effectively suppress the anti-corona phenomenon and improve the dust removal efficiency
