Title: SCR MIXER AND SCR DEVICE COMPRISING SAME
Abstract:
The present invention relates to an SCR mixer for mixing exhaust gas, and an SCR device comprising the same and, more specifically, to a mixing device for an exhaust gas post-treatment system of a diesel engine, the mixing device being for removing, by means of a catalyst and a filter, nitrogen oxide and diesel particulate matter contained in the exhaust gas to be discharged from an engine. According to the present invention, since a reducing agent is sprayed at an inner shell heated by exhaust gas, thereby increasing atomization and evaporation of reducing agent droplets, the SCR mixer has an effect of minimizing a phenomenon, occurring in a conventional mixer, in which a reducing agent is precipitated and sticks to the inner surface of an inner shell.
