Abstract
Abstract In construction of a contact-type ozonizer, one or more discharge electrodes are arranged substantially upright on a planar dielectric facing an electric field via magnetic attraction. Magnetic attraction provided stable and strong hold on the discharge electrodes without posing any excessive mechanical stress on the dielectric, upright arrangement of the discharge electrodes facilitates high rate of heat radiation and oxygen seizure is carried out in the most intensive zone of a magnetic field.
