Specific embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model statement
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment 1
As shown in figure 1, a kind of compact diesel rolling stock exhaust gas processing device, including engine 1 and processor body 2,
The processor body 2 is fixedly mounted on the shell body of engine 1 by the support 3 at two ends, envelope in the processor body 2
Equipped with oxidation catalyzer 4 and particle trap 5, the oxidation catalyzer 4 in sequential series of exhaust outlet 6 and particle of the engine 1 are caught
Catch device 5；The exhaust gas processing device also includes differential pressure pickup 7 and lambda sensor 8, and two air pressure of the differential pressure pickup 7 connect
Mouth is connected at the two ends of particle trap 5 by a pressure difference pipeline 9 respectively, and the sampling end of the lambda sensor 8 is arranged on exhaust
On mouth 6, the two ends of the oxidation catalyzer 4 are also equipped with a pair of temperature sensors 11.
In the present embodiment, for the ease of using the encapsulation of cramped construction, the oxidation catalyzer 4 and particle trap 5
Between by flange 12 fix hold together.
In addition, in the utility model, because particle trap 5 operationally has larger back pressure, passing through in air-flow
Axial motive force can be produced during flowing, therefore a metal clasp 10 is additionally provided with the outer end of the particle trap 5, passed through
Metal clasp 10 strengthens the supporting construction of particle trap 5, it is ensured that position stability of the particle trap 5 in axial direction, it is to avoid
Grain catcher 5 is exceeded because moving breakage discharges vehicle.
Considering the factor of loss of weight and reliability, the pressure difference pipeline 9 is used near one end of particle trap 5
Metal material is made, and pressure difference pipeline 9 is made near one end of differential pressure pickup 7 of rubber；Metal end can be avoided by particle
The heat damages that catcher 5 sends when regenerating, and the deadweight of whole pipeline then can be effectively reduced using quality of rubber materials using end,
The demand of many indexes is comprehensively adapted to.
