Abstract
A self-discharge type pulse charging electrostatic precipitator includes a high-speed switching element through which the electrical charge stored in a condenser is suddenly supplied to the electrostatic precipitator and the charge is dissipated in an internal resistance in the precipitator. A charging section of the electrostatic precipitator for one power source is divided into a plurality of charging sections which are coupled with each other through inductive elements. The electrostatic precipitator includes a device for supplying the electrical charge to each of the divided charging sections through the high-speed switching element successively in a time sharing manner and a charging capacitor having a capacitance which is substantially equal to a capacitance of the divided charging section. The electrostatic precipitator possesses enhanced precipitation efficiency by suppressing the back ionization and realizes reduction in cost of the power source.
