Description
Technical field
Exhaust aftertreatment technical field is the utility model is related to, mainly a kind of detachable exhaust gas from diesel vehicle post processing dress
Put.
Background technology
Vehicle exhaust after-treatment device DOC+CDPF on domestic market（Regenerate grain catcher）It is applied in combination,
And the DOC+CDPF in market（Regenerate grain catcher）It is that overall sleeve encapsulation forms, in the process, starts
Particulate matter in tail gas is filtered on hole wall by CDPF, will accumulate a certain amount of carbon distribution for a long time, is had a life time, is caught
Product, CDPF closure failures, DOC+CDPF can be blocked up by catching hole（Regenerate grain catcher）It can thoroughly scrap, can not use.
Utility model content technical problem to be solved in the utility model is to provide a kind of detachable diesel oil tailstock
Gas after-treatment device, to solve technical problem existing for prior art.
In order to solve the above-mentioned technical problem, technical scheme is used by the utility model：
A kind of detachable exhaust gas from diesel vehicle after-treatment device, includes blast pipe and escape pipe, it is characterised in that：It is described
One end of blast pipe is fixedly connected with the first sleeve by flange, and the porous carrier with catalyst is provided with the first sleeve, the
The other end of one sleeve is fixedly connected with second sleeve by flange again, and the diesel particulate with catalyst is provided with second sleeve
Filter, the other end of the second sleeve are fixedly connected by flange with escape pipe again.
A kind of described detachable exhaust gas from diesel vehicle after-treatment device, it is characterised in that：First sleeve contains body and
Inner liner is provided between one sleeve lining；Inner liner also is provided between second sleeve internal filter and second sleeve inwall.
A kind of described detachable exhaust gas from diesel vehicle after-treatment device, it is characterised in that：The outlet side of the blast pipe
Flare structure and it is fixed together by flange and the first sleeve；The inlet end of escape pipe also flare structure and
It is fixed together by flange and second sleeve.
The carrier of catalyst is carried on the utility model exhaust gas from diesel vehicle after-treatment device in first sleeve, is DOC (bavins
Oily car (machine) oxidation catalyst)；Second set of diesel particulate filter that catalyst is carried with, it is that CDPF (is carried and urged
The diesel particulate filter or wall-flow filter of agent).
The utility model the effect that flange connects can effectively make DOC (diesel vehicle (machine) oxidation catalyst),
CDPF (diesel particulate filter or wall-flow filter that carry catalyst) is divided into two parts, becomes two parts and acts on
On diesel engine truck exhaust pipeline, it changes the purposes for not influenceing diesel vehicle tail gas processor not only, if DOC or CDPF parts occur
Failure, damage, cleaning treatment can be carried out by removing single part, changed；Periodically DOC, CDPF are maintained, greatly enhanced
The service life of DOC+CDFP processing units.CDPF is such as pulled down, can carry out cleaning to the PM soots accumulated in CDPF can be effective
Strengthen CDPF service life, pull down DOC, CDPF and its catalyst is repaired, increase the service life.
The utility model has the advantages that：
The improvement of the utility model structure is ingenious, can be achieved individually to dismantle exhaust gas from diesel vehicle after-treatment device, convenient
Cleaning, maintenance work is repaired, improve catalyst activity, filter extends its service life except carbon, scale removal.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
