TITLE HIGH-INTENSITY IONIZER ABSTRACT OF THE DISCLOSURE A high-intensity ionizer including one or more planar discharge electrodes concentrically mounted in a tubular outer electrode. In one embodiment, the tubular electrode forms a venturi, and the planar discharge electrode in the form of a disc is mounted on an insulated probe in the throat of the ven- turi. The walls of the venturi are kept free of particulate matter by either a thin layer of water or an airstream along the wall of the venturi. Particulate matter is prevented from building up on the surface of the probe by an air vent extending around the probe upstream of the discharge electrode. A high voltage placed between the discharge and outer electrode gener- ates a high-intensity, corona current-producing, electrostatic field within the electrode gap between the discharge electrode and venturi. The electrostatic field expands radially and cir- cumferentially so that it is radially and circumferentially uniform. In another embodiment, a plurality of planar elec- trodes are mounted on a support electrode. The discharge elec- trodes are spaced apart from each other by at least 1.2 times the distance between the discharge and outer electrodes so that the electrostatic fields extending from adjacent discharge elec- trodes do not interfere with each other. The planar discharge electrodes may have varying diameters so that the intensity of the electrostatic fields through which a gas flowing through the tubular electrode sequentially passes is varied. Contaminants in gases flowing through the outer electrode thus sequentially flow through a plurality of alternating electrostatic charging fields and electric collecting fields.
