PROBLEM TO BE SOLVED : To provide an electrostatic precipitator which has a simpler structure of a high voltage generator to apply high voltage to each electrode of an electrostatic charge part and a dust collecting part of the electrostatic precipitator and which is capable of effectively controlling the re-scattering while maintaining high dust collecting capability.
SOLUTION : The high voltage generating means to generate high voltage of positive/negative dissymmetry having one-sided proportion of the negative or positive side is used as an application means of high voltage to the electrode of the dust collecting part of the electrostatic precipitator. As the positive/negative dissymmetry high voltage, it is preferable to use unsymmetrical square wave high voltage of which the output voltage value and output time of straight polarity and negative polarity are different and high voltage of straight polarity or negative polarity of which the output voltage is reduced to 0 V periodically and instantly and is restored again.
