<P>PROBLEM TO BE SOLVED: To prevent the lowering of a gas treatment capacity in a high speed stream in addition to a stable gas treatment capacity and a high gas treatment capacity and to achieve cost reduction. <P>SOLUTION: Honeycomb structures 4 are arranged with intervals along the direction crossing the passing direction (the direction from the inlet of a duct 1 to the outlet thereof) of a gas GS to be treated at a right angle. A first electrode 8 is arranged outside the honeycomb structure 4-1 arranged to one end in the direction crossing the passing direction of the gas GS to be treated among the honeycomb structures 4 and a second electrode 9 is arranged outside the honeycomb structure 4-4 arranged to the other end of the honeycomb structures 4. High voltage is applied across the upstream electrode 8 and the downstream electrode 9 to produce plasma in the through-holes (cells) 4a of the honeycomb structures 4 and the space gaps between the honeycomb structures 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
