Abstract

The invention belongs to the technical field of diesel engine tail gas post processing and relates to a box type post processing assembly for a diesel vehicle. The box type post processing assembly for the diesel vehicle comprises a particle trap, an oxidation catalytic reduction converter and a selective catalytic reduction converter. The particle trap and the oxidation catalytic reduction converter are connected to form a cylinder body and are fixed to a first partition plate, a second partition plate and a third partition plate. The selective catalytic reduction converter and a pipeline are arranged below the particle trap. The selective catalytic reduction converter sequentially penetrates the first partition plate, the second partition plate and the third partition plate, and the pipeline is supported to installation holes in the third partition plate and the second partition plate. The air inlet end of the pipeline is connected with a mixer. The box type post processing assembly for the diesel vehicle can work stably and efficiently, urea is evenly distributed on an SCR end face during work, and the phenomenon of urea crystallization is avoided.

Description

technical field [0001] The invention belongs to the technical field of aftertreatment of diesel engine exhaust, and relates to a diesel carriage type aftertreatment assembly. Background technique [0002] As the national emission standards for diesel vehicle exhaust pollutants become more and more stringent, the new emission standards have extremely strict standards for exhaust pollutants, and the strict emission standards cannot be met by only relying on the internal purification of the engine. To the Euro VI stage, it is necessary to control the content of particulate matter and nitrogen oxides in exhaust pollutants, so it is necessary to integrate DOC (oxidation catalytic converter), DPF (particulate filter) and SCR (selective catalytic reduction converter) Integrated in diesel vehicle aftertreatment. Existing diesel vehicle after-treatment that can meet the Euro VI emission standard is mostly a cylindrical structure, which has the disadvantages of taking up a lot of spa...
