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.

Abstract: An electrostatic precipitator includes an upright hollow body having a lower smoke inlet and an upper smoke outlet, with a pair of spaced horizontal partitions formed in the hollow body between the inlet and outlet. A set of parallel ducts extends vertically between the partitions, and a pair of distributor frames is arranged in the hollow body, with one of the distributor frames disposed over the ducts and the other of the distributor frames disposed under the ducts. Between the distributor frames is stretched a plurality of wires that extend through respective ducts. Furthermore, each of the distributor frames is formed with a plurality of terminals to be electrically connected to one electrode of a DC high-voltage power supply, but the ducts are adapted to be electrically connected to the other electrode of the DC high-voltage power supply.
