Description
Technical field
The invention belongs to motor-vehicle tail-gas processing techniques, exempt from more particularly, to a kind of for exhaust emissions of diesel engine processing
Dismantle pulse cleaning grain catcher.
Background technique
With the growth of GDP, domestic vehicle guaranteeding organic quantity is gradually increased.But with increasing for motor vehicle,
Tail gas pollution problem brought by motor vehicle also increasingly shows, and data show, motor vehicle is granular material discharged to have accounted for total release
30% or so.The engine of same displacement, diesel particulate discharge are 30~80 times of gasoline exhaust, reduce diesel engine
It is granular material discharged that reduction " haze " phenomenon is occurred, improve residents ' health and has great importance.
Diesel particulate trap (DPF) can effectively reduce diesel particulate discharge, to the filter efficiency of particulate matter
Up to 95%, it gradually applies at home at present.When using DPF, with gradually increasing for particulate matter, arrange diesel engine
Gas back pressure increases, and air inflow is reduced, and eventually leads to diesel combustion deterioration, power performance decline, and fuel economy deteriorates.Cause
This, when using DPF, the cleaning of particulate matter need to be carried out when accumulating more particulate matter, that is, carries out the regeneration of DPF.It is common at present
Regeneration be that hot recycling and manual maintenance regenerate.Wherein hot recycling mainly includes tail pipe jet regeneration, burner regeneration, electricity
The various ways such as spray regeneration, hot recycling can be carried out without dismantling DPF after in heater regeneration, cylinder.But due to diesel engine fault
Or diesel fuel oil problem is used, hot recycling DPF blocking is frequently resulted in, at this point, (or can only add by pressure-air blowback or washing
Add other additives) etc. the modes of manual maintenances carry out the regeneration of DPF.
Washing regeneration not will lead to the damage of DPF carrier, and particulate matter removal efficiencies when regeneration are high, in addition to clearing up diesel engine
Grain object, can also clean the ash content for being difficult to be fallen by hot recycling simultaneously, be applied on a small quantity on five diesel vehicle DPF of state at present.But
In order to guarantee the cleaning efficiency of particulate matter, generally requires to disassemble DPF sections from vehicle, carry out maintenance off-line.Due to
Grain trap is heavier, and causes each demolition and maintenance to devote a tremendous amount of time often with heat-insulation material thereon, thus shadow
The product for ringing user uses.
Summary of the invention
The purpose of the present invention is to provide a kind of pulse cleaning grain catchers free of demolition, to solve particle in the prior art
The problem of being cleaned again after disassembling from vehicle is needed when trap maintenance clean.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of pulse cleaning grain catcher free of demolition comprising grain catcher, wherein the one of the grain catcher
End is connected with oxidation catalyzer, and the other end is connected with exhaust pipe, and the other end of the oxidation catalyzer is connected with air inlet pipe
It connects, blowback maintenance end connecting flange, energy on the blowback maintenance end connecting flange is installed on the side wall of the oxidation catalyzer
Selectively it is sealed and installed with blowback maintenance end plug-hole flange or blowback maintenance grain catcher.
Particularly, reducer is provided in the exhaust pipe and air inlet pipe.
Particularly, first sensor seat is installed on the side wall of the oxidation catalyzer, is pacified on the first sensor seat
Equipped with temperature sensor before DOC.
Particularly, the grain catcher is equipped with second sensor seat, before being equipped with DPF on the second sensor seat
Temperature sensor.
Particularly, the both ends of the grain catcher by DPF sections of connecting flanges respectively with oxidation catalyzer and exhaust
Pipe is connected.
Particularly, air inlet connecting flange is provided on the air inlet of the air inlet pipe.
Particularly, the part on the grain catcher by two close end is mounted on DPF pressure difference gas-guide tube.
Particularly, the DPF pressure difference gas-guide tube is installed concentratedly in gas-guide tube fixing seat, and the gas-guide tube fixing seat is fixed
In on exhaust pipe.
Beneficial effects of the present invention are that the pulse cleaning grain catcher free of demolition can be realized compared with prior art
In the case where not dismantling grain catcher main body, the blowback cleaning and maintenance of soot is carried out to grain catcher, is not only simple in structure,
Convenient for operation；And substantially increase the cleaning efficiency of grain catcher；Reduce disposal costs.
Detailed description of the invention
Fig. 1 is under the normal operating conditions for the pulse cleaning grain catcher free of demolition that the specific embodiment of the invention provides
Structural schematic diagram；
Fig. 2 is under the maintenance and cleaning state for the pulse cleaning grain catcher free of demolition that the specific embodiment of the invention provides
Structural schematic diagram.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of pulse cleaning grain catcher free of demolition includes that particle is caught
One end of storage 1, grain catcher 1 is connected by DPF sections of connecting flanges 2 with oxidation catalyzer 3, and the other end passes through DPF sections
Connecting flange 2 is connected with exhaust pipe 4, and the centerline of grain catcher 1, oxidation catalyzer 3 and exhaust pipe 4 is in same vertical
On line, the other end of oxidation catalyzer 3 is connected with air inlet pipe 5, and air inlet connecting flange 6, oxidation catalysis are provided in air inlet pipe 5
First sensor seat 7 is installed on the side wall of device 3, temperature sensor before DOC, granule capturing are installed on first sensor seat 7
Second sensor seat 8 is installed on the side wall of device 2, temperature sensor before DPF is installed on second sensor seat 8.
Blowback maintenance end connecting flange 9 is installed, energy on end connecting flange 9 is safeguarded in blowback on the side wall of oxidation catalyzer 3
It is selectively sealed and installed with blowback maintenance end plug-hole flange 10 or blowback maintenance grain catcher 11, it is close on grain catcher 1
