Description
Technical field
The invention belongs to automobile manufacturing field, specifically a kind of After-treatment technics packaging system.
Background technique
Currently, existing After-treatment technics encapsulation mainly has square and "-" type, square structure occupied space is larger, one
Font structure occupied space is longer, and inevitably encounters that there are spaces is lesser to post-processing in automobile placement process
At this moment situation just needs a kind of new packing forms to combine DOC, DPF and SCR, and meets arrangement space.U
Type structure meets this feature, and width accounts for about square structure half, and occupied space is smaller, and meets DOC, DPF and SCR group
The requirement being combined.
U-shaped packaging system is that DOC and DPF are connected on top, by being vertically arranged mixer, is connected to the SCR of lower part.Tail gas
When by DOC, the upper catalyst oxidized portion hydrocarbon of DOC removes in tail gas using the filtration of DPF
Soot particulate matter sprays urea in mixer, by the effect of mixer, tail gas and urea is uniformly mixed, by SCR catalyst
Hydrocarbon partial and sulfide are eliminated in effect, reduce the pollutant concentration in tail gas, emission is made to meet environmental law
Rule.
Summary of the invention
The purpose of the present invention is to provide a kind of After-treatment technics packaging system.
To achieve the above object, the technical solution of the present invention is as follows: a kind of After-treatment technics packaging system, including air inlet
Tank, DOC unit, DPF unit, mixer, SCR unit and cyclone pipe are pacified between the air inlet tank and DOC unit by bracket I
Dress is fixed, and is fixed between the DOC unit and DPF unit by the installation of bracket II, the subjacent of the bracket I and bracket II
It is fixedly installed with SCR unit, the mixer is mounted on the position between DPF unit and SCR unit right end, and the mixer is right
End is connected and installed with cyclone pipe, is equipped with urea nozzle at the top of the mixer, expansion is equipped between mixer and cyclone pipe
It falls apart, the left side central location of the air inlet tank is equipped with air inlet, and the left side central location of the SCR unit is equipped with outlet
Mouthful.
The DOC unit is oxidizing catalytic converter, and the DPF unit is diesel particulate filter, the SCR unit
For the NO in tail gasXProcessing unit.
Due to the adoption of the above technical scheme, the invention has the benefit that the present invention keep DOC+DPF+SCR it is optimal after
Processing scheme, while occupied space is all smaller than square and "-" type encapsulation, meet the relatively narrow, length of post-processing arrangement space or so compared with
Short situation.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is main view of the present invention.
Fig. 2 is top view of the present invention.
In figure: 1, air inlet tank, 2, DOC unit, 3, DPF unit, 4, mixer, 5, SCR unit, 6, cyclone pipe, 7, bracket
I, 8, bracket II, 9, urea nozzle, 10, diffuser plate, 11, air inlet, 12, gas outlet.
Specific embodiment
As illustrated in fig. 1 and 2, the present invention includes air inlet tank 1, DOC unit 2, DPF unit 3, mixer 4, SCR unit 5 and rotation
Flow tube 6 is fixed between the air inlet tank 1 and DOC unit 2 by the installation of bracket I 7, between the DOC unit 2 and DPF unit 3
It is installed and is fixed by bracket II 8, the subjacent of the bracket I 7 and bracket II 8 is fixedly installed with SCR unit 5, the mixing
Device 4 is mounted on the position between 5 right end of DPF unit 3 and SCR unit, and 4 right end of mixer is connected and installed with cyclone pipe 6, institute
It states and urea nozzle 9 is installed at the top of mixer 4, diffuser plate 10, the air inlet tank 1 are installed between mixer 4 and cyclone pipe 6
Left side central location be equipped with air inlet 11, the left side central location of the SCR unit 5 is equipped with gas outlet 12.
Working principle: the tail gas for entering post-processing from the exhaust pipe of engine is entered in air inlet tank 1 by air inlet 11, is passed through
When DOC unit 2, the catalyst on DOC unit 2 understands catalysis oxidation hydrocarbon partial, makees using the filtering of DPF unit 3
With removing the soot particulate matter in tail gas, urea sprayed by urea nozzle 9 in mixer 4, by the effect of cyclone pipe 6, by tail
Gas and urea are uniformly mixed, and break up urea solution and tail gas again using diffuser plate 10, are made its mixing more evenly, are mixed
Tail gas eliminates hydrocarbon partial and sulfide by the catalyst action in SCR unit 5, reduces the pollutant in tail gas
Concentration, while the pore channels of carrier reduce noise, the tail gas for finally handling completion is discharged by gas outlet 12.
By calculating analysis, not only having met air velocity will not be too high for air inlet 11, gas outlet 12 and 6 diameter of cyclone pipe, but also
The requirement for meeting the mixed air velocity of mixer 4 presses the exhaust of post-processing not too high.
The above content is combining, specific preferred embodiment is made for the present invention to be described in detail, and it cannot be said that the present invention
Specific embodiment be only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, not
Under the premise of being detached from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention and is mentioned
The scope of patent protection that claims of friendship determine.
