<P>PROBLEM TO BE SOLVED: To provide a plasma reactor for gas treatment which has an increased length and an increased cross section of a plasma-generating region, is thereby capable of decomposition and purification of large amounts of harmful gases, is improved in adhesion of an electrode material to a dielectric and carries out plasma discharge effectively. <P>SOLUTION: This plasma reactor 4 decomposes and eliminates a harmful gas C passing through the plasma-generating region B formed by applying a voltage across a pair of electrodes E spaced apart with interposing the dielectric 5. The electrodes E are each formed by winding an electrode material 6 made of a strip like flat plate 7 or corrugated plate 8 on the outer circumference of the dielectric 5 having a circular cross-section, and the electrodes E are arranged concentrically. For example, three or more electrodes E are disposed in a plurality of layers, those having the same polarity are arranged alternately outward from the center to form the plasma-generating region B in two or more concentric layers. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
