Abstract
The utility model provides a kind of encapsulating structure of grain catcher, including DOC shells, DPF shells, end cap, cover board；The DOC shells are equipped with air inlet；DPF shells are equipped with gas outlet；DOC shells and DPF shells are fastened by bolts by flanged joint；It is welded with end cap away from one end of DOC shells in DPF shells, end cap, which is equipped with, safeguards opening；Cover board is connect by bolt with end cap, is open with closing the maintenance.Further, the shape of end cap is annular.The utility model solves the problems, such as that particle trap DOC+DPF passive regeneration later stage demolition and maintenance are convenient.
Description
Technical field
The utility model is related to the encapsulating structures of particle trap, belong to tail gas treatment system of diesel engine equipment and technology neck
Domain.
Background technology
Increasingly strict with diesel engine emissions regulations, exhaust aftertreatment technology is the technical measures that must be used.DOC+
DPF is mounted in diesel engine truck exhaust system, and particulate matter in exhaust is reduced by filtering（PM）Device.Diesel particulate filters
Device DPF captures particle, such as precipitin, inertia sedimentation or linear interception by the filter device of surface and internal mix.
DPF can be purified effectively 70% in exhaust --- and 90% particle is that purification diesel engine particulate matter is most effective, most straightforward approach
One of, realize commercialization in the world.Regenerative system can be divided into according to the difference of regeneration principle:Active regeneration system and quilt
Dynamic regenerative system two major classes.Initiative regeneration refers to improving the temperature in trap using outside energy, and particle is made to catch fire combustion
It burns.Passive regeneration refers to reducing the ignition temperature of particle using fuel oil additive or catalyst, enables particle normal
Diesel exhaust gas at a temperature of ignition.
DOC：Oxidation catalyzer；
DPF：Particulate filter.
Invention content
Convenient in order to solve particle trap DOC+DPF passive regeneration later stage demolition and maintenance, the utility model provides a kind of
The encapsulating structure of grain catcher.The technical solution adopted in the utility model is：
A kind of encapsulating structure of grain catcher, including DOC shells, DPF shells, end cap, cover board；
The DOC shells are equipped with air inlet；DPF shells are equipped with gas outlet；DOC shells and DPF shells pass through flange
Connection, is fastened by bolts；
It is welded with end cap away from one end of DOC shells in DPF shells, end cap, which is equipped with, safeguards opening；Cover board passes through bolt
It connect with end cap, is open with closing the maintenance.
Further, the shape of end cap is annular.
Further, DOC shells and DPF shells are all Stainless Steel Shells.
Further, air inlet is arranged on the circumferential surface of DOC shells.
Further, gas outlet is arranged on the circumferential surface of DPF shells.
The advantages of the utility model：This encapsulating structure is simple in structure, compact to design, easy to use, convenient for later stage dismounting dimension
Shield.This encapsulating structure is advantageous in that DPF rear end caps are connected using cover plate bolt, facilitates carry out demolition and maintenance, and drop
Low manufacturing cost.
Description of the drawings
Fig. 1 is the structure composition schematic diagram of the utility model.
Fig. 2 is the stereogram of the utility model.
Specific implementation mode
With reference to specific drawings and examples, the utility model is described in further detail.
The utility model is related to grain catcher, including DOC and DPF two parts, therefore corresponding encapsulating structure also wraps
Include DOC and two packed parts of DPF；
As shown in Figure 1, the encapsulating structure of grain catcher includes DOC shells 1, DPF shells 3, end cap 4, cover board 5；
The DOC shells 1 are equipped with air inlet 101；DPF shells 3 are equipped with gas outlet 301；DOC shells 1 and DPF shells
All it is Stainless Steel Shell；
DOC shells 1 and DPF shells 3 are connected by flange 2, are fastened by bolts；
It is welded with end cap 4 away from one end of DOC shells 1 in DPF shells 3, end cap 4, which is equipped with, safeguards opening；Cover board 5 passes through
Bolt is connect with end cap 4, is open with closing the maintenance；When needing to safeguard DPF, cover board 5 can be dismantled；
Two packed parts of the utility model are connected using flange bolt, and DPF encapsulates end cap and uses Split bolt and cover board
Connection, the configuration of the present invention is simple, when DPF is passive regeneration, demolition and maintenance are convenient, reduce customer care use cost, can be anti-
Multiple dismounting does not influence later stage normal use.
End cap 4 is preferably shaped to annular；Annular intermediate opening safeguards opening.
Air inlet 101 is arranged on the circumferential surface of DOC shells 1；Gas outlet 301 is arranged on the circumferential surface of DPF shells 3.
