Embodiment
It please join shown in Fig. 1 to Fig. 9, the utility model discloses a kind of tail-gas after treatment apparatus 100, for handling engine
Tail gas.The tail-gas after treatment apparatus 100 includes housing 1, the post processing carrier 2 that is installed in the housing 1 and at least
Electric hybrid module 3 of the part in the housing 1.The electric hybrid module 3 is positioned at the upstream of the post processing carrier 2.After described
Handle carrier 2 and include but is not limited to selective catalytic reducing agent (SCR).
In the utility model embodiment illustrated, the housing 1 is cylindrical, and it includes end cap 11 and dividing plate
12.Wherein, the first cavity 10 is formed between the dividing plate 12 and the end cap 11.The end cap 11 is in tabular, if it is provided with
Dry groove 111.
The housing 1 is provided with to install the mounting seat 13 of urea nozzle (not shown).The mounting seat 13 is provided with least
Part accommodates the mounting hole 131 of the urea nozzle and some mounting jaws 132 protruded into corresponding groove 111.So
Set, using the suitable thickness of mounting seat 13 and mounting seat 13 and the matching of electric hybrid module 3, eliminate the crystallization of mounting seat region or
