Abstract
An air cleaning apparatus includes a plurality of dust collecting electrodes alternately arranged with panel electrodes and spaced from each other at predetermined intervals to form air flow passages. Voltage is applied by a voltage source between the panel electrodes and the dust collecting electrodes and between ionizing wires, provided in the apparatus, and the dust collecting panel electrodes. The intervals between the panel electrodes and the dust collecting electrodes are selected to maintain a predetermined potential gradient in response to the value of the voltage applied between the panel electrodes and the dust collecting electrodes, whereby corona discharges are generated between the dust collecting electrodes and the ionizing wires to produce air streams. The dust collecting electrodes and the corresponding panel electrodes are coated with an ozone decomposition accelerating noble metal plating layer.
