Description
Technical field
The utility model is related to exhaust aftertreatment technical field, mainly a kind of heating-type diesel tailstock Flash Gas Compression Skid System.
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 is formed, in the process, starts
Particulate matter in tail gas is filtered on hole wall by CDPF, and a certain amount of carbon distribution will be accumulated 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）Can thoroughly it scrap, it is impossible to use.
Contain carbon monoxide in the tail gas of emission of diesel engine（CO）, nitrogen oxides（NOx）, hydrocarbon（HC）Outside, also
Containing fine particulates, fine particulates are based on carbon black, and it is molten that this particulate matter can form gas under the effect such as sunlight, temperature
Glue, shrouds in city overhead, haze haze weather is not only resulted in, can also take and wrap up in a large amount of chemical pollutants and drift in the air, very
Easily enter human body with the respiratory system of people, cause a series of diseases such as chronic nasopharyngitis, chronic bronchitis.
Utility model content technical problem to be solved in the utility model is to provide at a kind of heating-type diesel tail gas
Device is managed, to solve the technical problem of prior art presence.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used for：
A kind of heating-type diesel tailstock Flash Gas Compression Skid System, includes blast pipe and escape pipe, it is characterised in that：The exhaust
One end of pipe is fixedly connected with the first sleeve, the first sleeve by flange and is provided with the carrier with catalyst, the first sleeve
The other end is fixedly connected with transitional cylinder by flange again, and the other end of transitional cylinder is fixedly connected with second sleeve by flange again,
The diesel particulate filter with catalyst is provided with second sleeve, the other end of the second sleeve passes through flange and outlet again
Pipe is fixedly connected；It is provided with described transitional cylinder inwall in heating tube, transitional cylinder and is also equipped with temperature sensor, TEMP
On signal transmitting and receiving controller on the signal output part access car of device, the control heating tube heating of signal transmitting and receiving controller.
A kind of described heating-type diesel tailstock Flash Gas Compression Skid System, it is characterised in that：Carrier in first sleeve and first
Inner liner is provided between sleeve lining；Inner liner also is provided between second sleeve internal filter and second sleeve inwall.
The carrier of catalyst is carried on the utility model diesel vehicle tail gas processor in first sleeve, is DOC (diesel oil
Car (machine) oxidation catalyst)；Second set of diesel particulate filter with catalyst with is CDPF (with catalysis
The diesel particulate filter or wall-flow filter of agent).
The effect of the utility model flange connection 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 diesel oil
On vehicle exhaust pipeline, its change does not influence the purposes of diesel vehicle tail gas processor not only, if DOC or CDPF parts lose
Effect, damage, can carry out cleaning treatment by removing single part, change；Periodically DOC, CDPF are maintained, greatly enhanced
The service life of DOC+CDFP processing units.CDPF is such as pulled down, can carry out what cleaning can be effectively to the PM soots that accumulate in CDPF
Strengthen CDPF service life, pull down DOC, CDPF and its catalyst is repaired, increase the service life.
CDPF can catch soot as wall-flow filter in the utility model, be applied by DOC, CDPF activity loaded
The ignition temperature of layer reduction soot, particulate matter trap CDPF regeneration is realized by diesel vehicle own temperature, then pass through temperature
The detection of sensor, starts heating tube during low temperature, improve temperature conditionss needed for regeneration, and power of regeneration is more thorough, while DOC,
The active coating of CDPF loads, which possesses, makes oxygen storage oxygen catalysis characteristics, can be by the organic matter in HC, CO and PM in tail gas (SOF)
Oxidation removal, and NO is converted into the stronger NO2 of reproducibility, it is resolved diesel engine truck exhaust pollution.
PM soots are collected by CDPF and carry out second-time burning in tail gas, to reach more preferable burning situation, are passed by temperature
Sensor adjusts heating tube, manufactures more stable soot initiation temperature condition, obtains a kind of purification efficiency height, the bavin of service life length
The exhaust gas post-treatment device of oily car regeneration.
The utility model has the advantages that：
The utility model structure improves ingenious, can be achieved individually to dismantle exhaust gas from diesel vehicle after-treatment device, convenient
Cleaning, reparation maintenance work, extend its service life, cut and be provided with heating tube, can start heating tube in low temperature as needed,
Temperature conditionss needed for particulate matter trap CDPF regeneration are improved, power of regeneration is more thorough.
