A tail gas aftertreatment package comprises an outer shell, a first baffle, a second baffle, third aftertreatment carrier assemblies and a mixed tube assembly, and the first baffle and the second baffle are located in the outer shell and arranged in a spaced manner. Each third aftertreatment carrier assembly comprises a third shell and a third catalyst carrier encapsulated in the third shell. Eachthird shell is provided with a plurality of convex parts fixed with the second baffle and airflow channels located between the two adjacent convex parts, and the airflow channels penetrate through the second baffle to communicate with the third aftertreatment carrier assemblies. Compared with the prior art, the tail gas aftertreatment package has the advantages that by arranging the multiple convex parts on the third shells, the third shells are easily fixed on the second baffle; and in addition, by designing the airflow channels and making the airflow channels penetrate through the second baffle to communicate with the third aftertreatment carrier assemblies, extra flow guide elements are omitted, and the cost of the tail gas aftertreatment package is reduced.
一种尾气后处理封装,其包括外壳体、位于所述外壳体内且间隔布置的第一挡板与第二挡板、第三后处理载体组件以及混合管组件。所述第三后处理载体组件包括第三壳体以及封装在所述第三壳体内的第三催化剂载体。所述第三壳体设有与所述第二挡板进行固定的若干凸起部以及位于相邻两个凸起部之间的气流通道,所述气流通道贯穿所述第二挡板以与所述第三后处理载体组件相连通。相较于现有技术,本发明通过在第三壳体上设置若干凸起部,易于将第三壳体固定到第二挡板上;另外,通过设计气流通道,并使所述气流通道贯穿第二挡板以与第三后处理载体组件相连通,省略了额外的导流元件,降低了尾气后处理封装的成本。
