Abstract
The present invention relates to an exhaust gas purification apparatus and an exhaust gas purification method using the same. According to a specific embodiment, the exhaust gas purification apparatus comprises: a diesel oxidation catalyst (DOC) unit for converting nitrogen oxides (NO), contained in an exhaust gas introduced therein through a gas inlet portion, into nitrogen dioxide (NO); a composite diesel particulate filter (DPF) unit connected to the rear end of the DOC unit through an inflow line and removing harmful components including particulate substances and nitrogen oxides from the exhaust gas discharged from the DOC unit and introduced therein; and a circulation line disposed in the inflow line so as to introduce the exhaust gas discharged from the DOC unit into the gas inlet portion.
