Furnace device for eliminating volatile organic compounds (VOCs)

Abstract

This invention relates to a furnace device for eliminating volatile organic compounds in exhaust gas. The furnace device has a hollow body ( 10 ) with a gas inlet ( 13 ) and a gas outlet ( 11 ), a positioning device ( 20 ) mounted inside the body ( 10 ) and an arc generator ( 30 ) attached to the positioning device ( 20 ). The arc generator ( 30 ) has multiple cylindrical chambers ( 31 ) for accommodating the exhaust gas and multiple central rods ( 32 ) respectively penetrating through the multiple cylindrical chambers ( 31 ). In each chamber ( 31 ), an inner periphery of the chamber ( 31 ) serves as an electrode, and the central rod ( 32 ) serves as another electrode. When an effective potential difference is applied to the electrodes, arcs are generated between the inner periphery of the chamber ( 31 ) and the central rod ( 32 ) inside the chamber ( 31 ). Thereby, volatile organic compounds in the exhaust gas are burned and decomposed effectively and completely by the generated arcs.
