ABSTRACT:
Herein disclosed is an air cleaner comprising: means defining an air passage, a plurality of corona discharge electrodes and a coupling discharge electrode arranged upstream of an air passage, being connected to a high voltage source for effecting a corona discharge downstream of the air passage for collecting the air-borne dust which has been charged by the corona discharge. The coupling discharge electrode is formed as a plate with a number of circular apertures therein, and each of the discharge electrodes has a multiplicity of leading ends shaped as sharp points arranged at the respective centers of the circular apertures and terminating generally on the plane thereof. The velocity of the air flow is increased in passage through the apertures to prevent the air cleaner from getting clogged. The corona discharge electrodes take the form of metal plates or bars extending generally rigidly across the air passage and mounted to the air cleaner at their ends, the sharp points being integral with the plates or bars and projecting therefrom toward the coupling electrode apertures.
