ABSTRACT:
An electronic air cleaner is disclosed in which the corona discharge wire and the counterelectrode are positioned outside the flowpath of dust-laden air. Diverging electric force lines are discharged from the discharge wire electrode, which is nearer the flow path than the counterelectrode, when a high voltage is applied and ions are directed into the passing airflow path in a reacting area or zone. Dust contained in the air flow path is electrically charged by the ions and collected on a filter, which may also be electrically charged, positioned downstream from the reacting zone. In the device the discharge wire is not directly exposed to the dust-laden air, the electrically charged particles being collected on a separate, easily cleaned filter. The design of the electronic air cleaner requires less maintenance, easier cleaning and a longer period of operational quality.
