Document Type and Number:
WIPO Patent Application WO/2021/213146
Kind Code:
A1
Abstract:
An exhaust gas aftertreatment package, comprising an outer housing (1), a first baffle plate (21) and a second baffle plate (22) that are located in the outer housing (1) and arranged at an interval, third aftertreatment carrier assemblies (53), and a mixing tube assembly (6). Each of the third aftertreatment carrier assemblies (53) comprises a third housing (531) and a third catalyst carrier (532) packaged in the third housing (531). Several protrusion portions (5311) fixed to the second baffle plate (22) and an airflow channel (5312) located between two adjacent protrusion portions are provided on the third housing (531), and the airflow channel (5312) runs through the second baffle plate to be communicated with the third aftertreatment carrier assembly (53). By providing the several protrusion portions (5311) on the third housing (531), the third housing (531) is easy to be fixed to the second baffle plate (22); in addition, by designing the airflow channel (5312) and enabling the airflow channel (5312) to run through the second baffle plate (22) to be communicated with the third aftertreatment carrier assembly (53), an additional flow guide element is omitted, and the cost of the exhaust gas aftertreatment package is reduced.
