Description
Technical field
The utility model is related to motor vehicle tail-gas purifying technical field, more particularly to a kind of catalysis of integrated diesel car to eliminate the noise
Device assembly.
Background technology
As the increasingly increase of vehicles number, the pollution of vehicle exhaust are also increasingly serious, huge wound is brought
Evil, at the same time country also increases the dynamics of pollution administration, and progressively requires to carry out the discharge standard of the even more high of state five.But
It is that must install blender before SCR postprocessor in the market additional, it is ensured that urea can be abundant in entrance catalyst converter leading portion
Hydrolysis, it is higher for vehicle space arrangement requirement because mixer length is more long, while cost also increases, and gas exhaust piping
Lengthening causes delivery temperature to lose influence catalyst transformation efficiency.
Therefore, the novel diesel vehicle SCR catalyzed muffler devices of a kind of function admirable and structure are urgently studied.
SCR technology (SCR) is directed to a handling process of NOx in exhaust gas from diesel vehicle discharge, that is, urging
In the presence of agent, reducing agent ammonia or urea are sprayed into, the NOx in tail gas is reduced into N2And H2O。
Utility model content
The purpose of this utility model is to provide a kind of integrated diesel car catalytic muffler assembly, to solve above-mentioned technology
Problem.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of integrated diesel car catalytic muffler assembly, it is characterised in that：Including columnar body, the right-hand member of body
Air inlet is set, and the left end of body sets gas outlet, gas outlet and after silencer integrally connected, and the intrinsic middle part is set
Selective reducing catalyst SCR, the right side of selective reduction catalyst SCR is preceding silencing cavity in body, selectivity in body
The left side of reducing catalyst SCR is rear silencing cavity, and the after silencer is located in rear silencing cavity, is provided with the preceding silencing cavity
Two pieces of flow distribution plates, hybrid chamber is constituted between two pieces of flow distribution plates, and preceding muffler is provided with hybrid chamber.
The body right-hand member is additionally provided with urea jet, the injection direction of urea jet and the axial direction of body into 30-
45 ° of angles.
The injection direction of the urea jet is with mixing duct axially into 35 ° of angles.
It is provided with the body of rear silencing cavity and plug screw is screwed in spiro pluging hole, spiro pluging hole.
Motor-vehicle tail-gas enter air inlet after producing, urea carries out injection and mixes with tail gas by nozzle, by preceding noise reduction
The flow-disturbing effect of device, on the one hand reduces noise, on the other hand enables tail gas uniformly through selective reduction catalyst SCR.
The design of hybrid chamber can lengthen instroke space, while reducing air velocity, and be analyzed by accurate CFD
The flow velocity of catalyst converter end face is consistent, it is ensured that the smooth homogeneous and ammonia distributing homogeneity of catalyst converter.Hybrid chamber sets
It is counted as using and directly eliminates the blender that catalytic muffler leading portion is installed additional.
Temperature in order to make preprocessor reach catalyst required for temperature requirement.Specially in selective reduction
SCR one big cylinder of outer surface cover, plays a part of insulation.
From SCR postprocessor gas out again by after silencer, the effect of noise reduction so can be further played
Really.The design of silencing cavity instead of muffler, reduce chassis arrangement space, reduce cost.
The utility model can effectively in purifying motor tail gas harmful substance, reach the purpose of protection air, and
Further be conducive to the health of human body.
Profile of the present utility model and big I are adjusted according to the size of vehicle, but internal structure and principle are constant.This collection
Preprocessor into catalyzed muffler can to greatest extent save chassis space, reduces cost.It is particularly narrow in chassis space
Future development is with the obvious advantage in small light truck.
