<P>PROBLEM TO BE SOLVED: To provide a power source for a plasma reactor, the plasma reactor, an exhaust emission control device and an exhaust emission control method, realizing both PM collection and combustion/removal. <P>SOLUTION: This power source for the plasma reactor is constituted so as to generate superimposed voltage (c) having a DC voltage component (a) and a pulse voltage component (b). The plasma reactor has a pair of electrodes sandwiching an exhaust gas flow passage, and is constituted such that voltage is applied to the electrodes by the power source for the plasma reactor. The exhaust emission control device is provided with the plasma reactor and a PM collection part in the downstream side of an exhaust gas flow. In the exhaust emission control method, the superimposed voltage (c) having the DC voltage component (a) and the pulse voltage component (b) is applied to an electrode of the plasma reactor with the pair of electrodes sandwiching the exhaust gas flow passage. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
