The invention discloses a tail gas aftertreatment package. The tail gas aftertreatment package comprises a first aftertreatment carrier, a second aftertreatment carrier, a third aftertreatment carrierand a mixing assembly, wherein the mixing assembly comprises a fourth shell, a mixing pipe located in the fourth shell, a perforated pipe located in the mixing pipe and a reflecting plate located atthe lower end of the mixing pipe, the reflecting plate and the mixing pipe are arranged at an interval, the fourth shell is provided with a first cavity, a second cavity and a partition plate, the mixing pipe comprises a plurality of rotational flow pieces exposed in the first cavity and a plurality of penetrating holes exposed in the second cavity, and the mixing assembly further comprises a baffle located in the second cavity and located on the side face of the reflecting plate, wherein the baffle is closer to the third aftertreatment carrier than the reflecting plate. By means of the arrangement, airflow can be evenly distributed on the inlet end face of the third aftertreatment carrier.

    一种尾气后处理封装,其包括第一后处理载体、第二后处理载体、第三后处理载体以及混合组件;所述混合组件包括第四壳体、位于所述第四壳体内的混合管、位于所述混合管中的多孔管以及位于所述混合管的下端且与所述混合管间隔设置的反射板,所述第四壳体设有第一腔体、第二腔体以及隔板,所述混合管包括暴露在所述第一腔体中的若干旋流片以及暴露在所述第二腔体中的若干穿孔。所述混合组件还包括位于所述第二腔体中且位于所述反射板的侧面的挡板,其中所述挡板比所述反射板更靠近所述第三后处理载体。如此设置,有利于将气流均匀地分布于所述第三后处理载体的入口端面。
