Abstract
An electrostatic precipitator is disclosed. The electrostatic precipitator includes an ionization unit configured to generate ions and a dust collection unit configured to electrically collect dust to which the ions are attached. The ionization unit is an ionizer that applies a predetermined voltage to an electrode needle to cause a corona discharge to generate the ions having the same polarity as a polarity of the applied voltage. The dust collection unit includes a high-voltage electrode disposed having a plurality of gaps for passing the dust to which the ions are attached, and a dust collection board disposed at a rear stage of the high-voltage electrode. A polarity of the voltage applied to the electrode needle of the ionization unit and the polarity of the voltage applied to the high-voltage electrode are set to the same polarity.
