<p>PURPOSE:To obtain the plasma-process waste gas purifying device with the contact efficiency between the plasma and waste gas increased and capable of being scaled up by arranging a wire-type discharge electrode at the center of a honeycomb couter electrode consisting of a polygonal-sectioned prismatic cylinder. CONSTITUTION:A reactor provided with one discharge electrode 13 and one counter electrode 14 and a high-voltage pulde power source 12 connected to both electrodes 13 and 14 are furnished in a flue. The discharge electrode 13 is of wire type, the honeycomb counter electrode 14 consists of plural polygonal- sectioned prismatic cylinders 14a, the wire-type discharge electrode 13 is set at the center of each prismatic cylinder 14a of the counter electrode 14, and the cylinder is placed in a reactor so that each opening of the cylinder 14a is directed in the flow direction of waste gas. Consequently, since the non-dense plasma part is not formed, contact efficiency is improved, and the device is scaled up by increasing the number of cylinders.</p> |
