Comparative Study of Distribution of Collecting Plate Current Density on Electrostatic Precipitations with High Direct Current and Pulse Power Supply

ESP has been applied widely in environmental protection. In this paper, the measure methods and tested setup of the collecting plate current density on ESP were introduced. In pulse engergization and direct current power supplies, distribution of collecting plate current density in vertical and parallel direction of corona discharge line on ESP are contrastively measured. It is concluded that distribution of collecting plate current density on ESP with pulse engergization was more uniform than that with direct current power supply in experiments, and it is advantageous to improve dust performance of ESP.
