Method for self-cleaning a dust collection electrode of an electrostatic precipitator for air conditioner use

摘要

In an electronic dust collector or an air conditioner equipped with said dust collector for collecting dust contained in air by a discharge effect between the discharge electrode and the dust collection electrode, there is provided a catalyst layer for oxidizing and decomposing the deposited dust on the surface of the dust collection electrode, which contains a heater for self-cleaning. By controlling passage of electricity to the heater so as to have the dust collection electrode show moderate temperature elevation during the self-cleaning of the dust collection electrode, it becomes possible to make stepwise oxidation and decomposition of the dust deposited on the dust collection electrode, thereby cleaning the dust collection electrode by removing the dust on the dust collection electrode while suppressing generation of smoke and odor by firing of dust.
