METHOD AND APPARATUS FOR CLEANING RELEASE GASES Russian patent published in 1997 - IPC

FIELD: gas purification. SUBSTANCE: invention concerns removing impurities from gases employing ozone-catalytic technique and may be utilized in chemical industry, mechanical engineering, and other areas. Ozone is generated in catalyst beds under high voltage and frequency. According to invention, units of apparatus involved accommodate electrodes and, over the first catalyst bed, disk with blades and capacitance generator is disposed. EFFECT: enhanced gas cleaning efficiency and ozone generation is combined with catalytic oxidation owing to that catalyst functions as dielectric component of ozonator. 5 cl, 3 dwg
