Description
Technical field
The utility model is related to a kind of clam shell air intake structures, are mainly arranged in the front end of commercial car oxidation catalytic converter,
Belong to vehicle exhaust after-treatment device technical field, specially a kind of clam shell air intake structure with flow-disturbing partition board.
Background technology
It is increasingly harsh with future emission regulation, to ensure that each pollutant reaches respective stage emission regulation, post-process
The use of device is essential.
Use oxidation catalytic converter（DOC）Commercial car aftertreatment products in, air inlet pipeline and oxidation catalytic converter
When the perpendicular arrangements of DOC, it is limited to arrangement space, traditional air intake structure is more difficult to meet design requirement.
Invention content
The purpose of this utility model is to devise a kind of clam shell air intake structure with flow-disturbing partition board, and the structure is in air inlet pipeline
With oxidation catalytic converter at being arranged vertically and the situation of chassis arrangement space anxiety, oxidation catalytic converter can be allowed airflow into
Flow field meet uniformity index requirement, the transformation efficiency and service life of oxidation catalytic converter can be improved.
Technical solution according to the present utility model, the clam shell air intake structure with flow-disturbing partition board, including inlet guide pipe
With clam shell end cap, the inlet guide pipe includes distortion boot segment and straight tube boot segment；The clam shell end cap is equipped with flow-disturbing partition board.
Further, flow-disturbing partition board both sides band flange, and using flanging welded in clam shell end cap.
Further, the clam shell end cap is flat.
Further, the opening diameter on the flow-disturbing partition board is 8-12mm.
In use, the arrival end of distortion boot segment is connected with front end booster, outlet end and the oxidation of clam shell end cap are urged
The outer barrel for changing converter is connected.Plane where the flow-disturbing partition board passes through the central axes of oxidation catalytic converter.
The beneficial effects of the utility model are：It is compact-sized, it is small to arrangement installation space demand, it is suitable for chassis and arranges
The case where space is nervous and perpendicular with the oxidation catalytic converter arrangement in air inlet pipeline direction, effectively solves to turn into oxidation catalysis
Change device flow field uniformity problem not up to standard, to improve the transformation efficiency and service life of catalytic converter.
Description of the drawings
Fig. 1, Fig. 2 are the structural schematic diagram of the utility model.
Fig. 3, Fig. 4 are the structural schematic diagram of the flow-disturbing partition board of the utility model.
Reference numeral：Distort boot segment 1, straight tube boot segment 2, clam shell end cap 3, flow-disturbing partition board 4.
Specific implementation mode
With reference to specific embodiments and the drawings, the utility model is described in further detail.
Clam shell air intake structure with flow-disturbing partition board as shown in the figure, including inlet guide pipe and clam shell end cap 3, wherein into
Gas guiding tube includes distortion boot segment 1 and straight tube boot segment 2.In use, distortion boot segment 1 arrival end by bellows with before
End booster is connected, and the outlet end of clam shell end cap 3 is connected with the outer barrel of oxidation catalytic converter.In clam shell end cap 3
Equipped with flow-disturbing partition board 4, the plane where flow-disturbing partition board 4 passes through the central axes of oxidation catalytic converter.Specifically, flow-disturbing partition board 4
Both sides band flange, and using flanging welded in clam shell end cap 3.Opening diameter on flow-disturbing partition board 4 is 8-12mm, in a reality
Apply in example is 10mm.Clam shell end cap 3 is flat.
Operation principle：The exhaust gas that engine work generates enters distortion boot segment 1 by front end exhaust manifold and booster
And in straight tube boot segment 2, as shown in Figure 1, entire air intake structure shape is a class tangential admission scheme, air-flow is into clam shell
Afterwards can be there are one the effect rotated, because flat clam shell leading inside is welded with the flow-disturbing partition board 4 with flange, which can be to having
The incoming of rotating tendency generates the effect of blocking and diffusion so that air-flow mixes fully in flat clam shell end cap, the flow-disturbing every
Circular hole is made on plate, therefore the structure not will produce larger effect of shutting off, within the acceptable range, mixing is filled for the increase of back pressure
The exhaust gas divided enters in the oxidation catalytic converter at rear, improves the transformation efficiency and service life of catalytic converter.
