(57) Abstract: The exhaust gas purification device adsorbs NO X in the exhaust gas by a compound having a brownmillerite-like structure, to purify the exhaust gas by decomposing NO X by plasma energy. In this exhaust gas purifying apparatus, a compound having a brown-mirrorite-like structure is attached to a filter body 5 constituting a filter 3, and a pair of wire nets 4, 6 are arranged on both sides of the filter body 5, respectively. the radical state by adsorbing NO X in the oxygen defect exhaust gas of a compound having the Miraraito like structure, the NO X in the radical state is decomposed disappear plasma energy, nitration of the compound with a brownmillerite-like structure reaction To prevent |
