Description
Technical field
The utility model belongs to a kind of diesel engine vent gas after-treatment device, particularly a kind of penetrating type granule capturing post-processor assembly.
Background technique
Diesel engine has obvious advantage, particularly CO than petrol engine in power character, Economy and reliability
2discharge very low, its purposes expands in all kinds of vehicle gradually.But it is that nitrogen oxide and particulate emission are high that diesel engine exists maximum problem.Present stage, diesel exhaust aftertreatment was only by process in machine, predominant emissions NOx 5.0 (g/kwh), PM 1.0 (g/kwh).But along with Chinese emission control regulations are more and more tighter, and domestic diesel engine performance and oil product problem, depend emission controls by improving combustion measure alone and seem unable to do what one wishes, be therefore necessary to take the outer after-treatment system of machine to reach emissions object, improve exhaust level.In vent systems, increase formula granule capturing post-processor assembly, predominant emissions in tail gas can be made to be reduced to NOx 3.5 (g/kwh), PM 0.02 (g/kwh).
Penetrating type granule capturing post-processor assembly technology is the outer post-processing technology of a kind of machine of vehicle diesel engine, effectively can improve the discharge of diesel engine vent gas carbon hydride, and the control of particulate matter.This technology is oxidized the HC in tail gas, solvable PM, CO by diesel oil oxidation agent carrier, increases delivery temperature; Particle trap catches the PM particulate matter in tail gas, then the NO2 reaction formed in oxidator is melted, and forms passive regeneration.There is poor fluidity, the problem that crushing is not moderate in current penetrating type granule capturing post-processor assembly.
Summary of the invention
The utility model provides a kind of penetrating type granule capturing post-processor assembly, to solve the poor mobile performance, the crushing that exist at present problem moderate not.
The technological scheme that the utility model is taked is: be connected with enclosure interior interference after liner parcel diesel oil oxidation agent carrier, particle trap is fixedly connected with enclosure interior by baffle plate, end cap one is fixedly connected with housing two ends respectively with end cap two, suction tude and end cap one grafting, outlet pipe and end cap two grafting, diesel oil oxidation agent carrier front end is air-inlet cavity, and particle trap rear end is exhaust cavity, this suction tude and outlet pipe has respectively the perforation of some.
There is the parallel channels one of through both ends of the surface described diesel oil oxidation agent carrier inside, has catalyst coat at the internal surface of each parallel channels.
There is the parallel channels two of through both ends of the surface described particle trap inside.
The utility model has the advantages that novel structure, there is good flowing properties, crushing is moderate, fluid mechanics (CFD) flow analysis, FEA analyze (stress analysis) and acoustic analysis demonstration as calculated, show that it has good flowing properties, crushing is moderate, cleaning of off-gas performance is high, the feature of good endurance, effectively can reduce carbon hydride and PM discharge quantity of particulate matter, improve the emission level of diesel engine.

Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
Liner 3 is connected with the inner interference of housing 1 after wrapping up diesel oil oxidation agent carrier 2, particle trap 6 is fixedly connected with enclosure interior by baffle plate 7, end cap 1 is fixedly connected with housing two ends respectively with end cap 29, suction tude 5 and end cap 1 grafting, outlet pipe 8 and end cap 29 grafting, diesel oil oxidation agent carrier front end is air-inlet cavity, and particle trap 6 rear end is exhaust cavity, this suction tude 5 and outlet pipe 9 has respectively the perforation of some.
There is the parallel channels 1 of through both ends of the surface described diesel oil oxidation agent carrier 2 inside, has catalyst coat at the internal surface of each parallel channels.
There is the parallel channels 2 61 of through both ends of the surface described particle trap 6 inside.
Diesel motor exhaust is entered by suction tude 5, diesel oil oxidation agent carrier 2 is flowed through after air-flow restructuring, oxidation reaction is carried out in parallel channels 21, eliminate carbon hydride, then through particle trap 6, after parallel channels 61 carries out the seizure of PM particulate matter, air-flow is discharged from tail pipe by outlet pipe 9, the perforation that suction tude, outlet pipe are arranged, can make exhaust air flow even, improve the transformation efficiency of carbon hydride.
