PLASMA REACTOR POWER SOURCE, PLASMA REACTOR, EXHAUST GAS PURIFICATION DEVICE AND EXHAUST GAS PURIFYING METHOD

摘要

There are provided a plasma reactor power source (38), a plasma reactor (30), an exhaust gas purification device and an exhaust gas purifying method, whereby both collection and combustion removal of PM are accomplished. The plasma reactor power source (38) of this invention is characterized by generating a superimposed voltage (c) having a direct current voltage component (a) and a pulse voltage component (b). The plasma reactor (30) is characterized by having an electrode pair sandwiching an exhaust gas flow channel, wherein a voltage is applied to the electrodes (34, 36) by a plasma reactor power source (38) according to the invention. The exhaust gas purification device is characterized by comprising a plasma reactor (30) of the invention and a PM collector downstream from the exhaust gas flow.
