Abstract
The utility model discloses the diesel engine tail gas particle catcher of a kind of pair of DPF structure, including tail gas collecting device, defecator, exhaust apparatus；Described tail gas collecting device, defecator and exhaust apparatus mechanically connect, it is sequentially set with a DPF and the 2nd DPF according to the direction of inlet air filtration inside described defecator, first DPF has macroscopic void, in order to reach longer service life, wall-flow type carrier inside duct wall body surface can be using the large micropore technology higher than 12um.And second DPF adopts standardized product, in order to reach preferable seizure effect, wall-flow type carrier inside adopts the micro-pore diameter of standard.It is provided with two DPF assemblies in filtration supports to be filtered, by having the different micropore of size on two DPF, stagewise reduces the discharge of tail gas impurity, extends the service life of DPF.
Description
Technical field
This utility model is related to a kind of plant equipment, the diesel engine tail gas particle catcher of specifically a kind of pair of DPF structure.
Background technology
Core product wall-flow type carrier itself (letter below in worldwide diesel engine tail gas particle catcher at present
Claim DPF) structural requirement, two ends mode of must interlocking all is closed all ducts, and occurs more difficult complete after DPF blocks
All clear is managed.
And Chinese diesel vehicle market generally existing diesel fuel oil not up to standard, electromotor burn oil phenomenon is many, portion
The delivery temperature of separating vehicles is low, leads to the soot particulate discharging to be very easy to block the air flue of DPF carrier, thus forming blocking
After PM cannot completely regenerate and burn.In this case, DPF carrier is easy for losing efficacy and then leading to all of subassembly product invalid.
So reducing the blocking of of DPF carrier itself is the basic of solve problem.
Utility model content
This utility model purpose is to provide the diesel engine tail gas particle catcher of a kind of pair of DPF structure, and purpose extends granule
The service life of catcher DPF, reduces maintenance input cost.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：
The diesel engine tail gas particle catcher of a kind of pair of DPF structure, including tail gas collecting device, defecator, aerofluxuss dress
Put；Described tail gas collecting device, defecator and exhaust apparatus are mechanically connected, according to air inlet inside described defecator
The direction filtered is sequentially set with a DPF and the 2nd DPF, a DPF has a number of macroscopic void, realizes coarse filtration,
2nd DPF then realizes fine straining using the technical requirements of standard DPF.
Further, described exhaust apparatus is connected by flange or anchor ear mode with defecator.
Preferably, described tail gas collecting device is provided with air inlet.
Preferably, the sectional area of described macroscopic void is more than the sectional area of exhaust apparatus.
The beneficial effects of the utility model are：
It is provided with two DPF assemblies in filtration supports to be filtered, realize coarse filtration and the purpose of fine straining by two DPF,
Reduce the accumulation of fine straining DPF exhaust particulate thing impurity, increase service life.
Black smoke PM material in motor exhaust first passes around coarse filtration DPF, and first road DPF infrastructure product is opened in carrier inlet end
There is a number of macropore, to tail gas coarse filtration, reduce the bulky grain in tail gas, the secondary fine being then passed through PDF filters, and reaches
Improve the purpose filtering tail gas ability.

Specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can be by right
The multitude of different ways limiting and covering is required to implement.
As shown in figure 1, this utility model discloses the diesel engine tail gas particle catcher of a kind of pair of DPF structure, including tail gas
Collection device 3, defecator, exhaust apparatus 4；Described tail gas collecting device 3, defecator and exhaust apparatus 4 mechanical system
(mode such as screw thread, anchor ear) connect, inside described defecator according to the direction of inlet air filtration be sequentially set with a DPF2 and
2nd DPF1, a DPF2 has a number of macroscopic void 6 (macroscopic void having may also be employed the mode of cannelure), real
Existing coarse filtration, in practical application, in order to reach longer service life, wall-flow type carrier inside can adopt micro- higher than 12um
Hole, as long as such DPF2 is existing with regard to so that service life reaches more than 2 years, breaking through by way of gases at high pressure are cleared up
Have DPF technology former row difference environment under a few days service life limit.2nd DPF1 then adopts the technology of standard DPF to want
Realistic existing fine straining.Because of the filtration of coarse filtration DPF, the service life of fine straining DPF is also effectively extended, and fine straining is permissible simultaneously
Periodic replacement.
Described defecator is connected by flange or anchor ear mode with exhaust apparatus 4.And a DPF2 macroscopic void
Sectional area design requirement is more than the sectional area of exhaust apparatus 4, and the gas so entering exhaust apparatus 4 will not block exhaust apparatus 4
Pipeline.
It is provided with air inlet 5 on described tail gas collecting device 3.
Above-described this utility model embodiment, does not constitute the restriction to this utility model protection domain.Any
Modification, equivalent and improvement made within spirit of the present utility model and principle etc., should be included in this utility model
Claims within.
