排气处理装置
摘要：
本发明涉及一种排气处理装置，用于内燃机的排气设备的排气处理装置，具有：包括壳体进入部和壳体排出部的排气处理壳体；在排气处理壳体中的排气处理单元，包括跟随壳体进入部的排气处理单元进入部和排气处理单元排出部；在排气处理壳体中的SCR催化器布置结构，包括跟随排气处理单元排出部的SCR催化器布置结构进入部和SCR催化器布置结构排出部；在SCR催化器布置结构进入部上游的用于释放反应剂的反应剂释放布置结构；在排气处理壳体中，在排气管路中形成的排气通道从排气处理单元排出部通至SCR催化器布置结构进入部，使得在SCR催化器布置结构排出部上离开SCR催化器布置结构的排气至少局部地环流排气管路。
摘要（英）：

The invention relates to an exhaust gas treatment device. The exhaust gas treatment device for exhaust equipment of an internal combustion engine, comprises: an exhaust gas treatment housing with a housing inlet and with a housing outlet; an exhaust gas treatment unit in the exhaust gas treatment housing with an exhaust gas treatment unit inlet following the housing inlet and with an exhaust gas treatment unit outlet; an SCR catalytic converter device in the exhaust gas treatment housing with an SCR catalytic converter device inlet following the exhaust gas treatment unit outlet and with an SCR catalytic converter device outlet; a reactant releasing device for releasing reactant upstream of the SCR catalytic converter device inlet; and an exhaust gas duct formed in an exhaust gas pipe, theexhaust gas duct leading in the exhaust gas treatment housing to the SCR catalytic converter device inlet such that exhaust gas leaving the SCR catalytic converter device at the SCR catalytic converter device outlet flows around the exhaust gas pipe in at least some areas.
