Abstract

A pollutant destruction apparatus has a corona discharge reactor attached to conductive end plates at the ends of the reactor. The reactor has inner and outer electrodes deposited respectively on the inner and outer surfaces of a hollow dielectric cylinder, the interior of which defines the reactor chamber. The inner electrode is electrically connected to the end plates, which are grounded, while the outer electrode is connected to a high-voltage power supply to establish a corona discharge. The outer electrode is tapered near the ends of the reactor to reduce the possibility of arcing. A hole in each end plate is aligned with the reactor chamber to allow gas flow into and out of the reactor.
