EXHAUST GAS POST-PROCESSING DEVICE AND METHOD THEREFOR

摘要

The objective of the present invention is to provide an exhaust gas post-processing device, which simplifies an exhaust gas post-processing system so as to lower manufacturing costs and reduce installation space. The exhaust gas post-processing device according to one embodiment of the present invention comprises: an exhaust pipe allowing the exhaust gas of an engine to flow therethrough; a hydrocarbon selective catalytic reduction (HC SCR) provided in the exhaust pipe so as to remove nitrogen oxides contained in the exhaust gas; and a plasma reactor connected to the exhaust pipe between the engine and the HC SCR so as to modify fuel, thereby generating a reducing agent of hydrogen and an HC species or combusting the fuel.
