Abstract
The utility model relates to the technical field of exhaust gas purification, and discloses a catalytic converter based on a radial POC structure. The catalytic converter based on the radial POC structure comprises a catalytic converter body, a DOC and a POC, wherein a smoke inlet is formed in the front end of the catalytic converter body, a smoke exhaust port is formed in the rear end of the catalytic converter body, the DOC is arranged at the front end inside the catalytic converter body and is near the smoke inlet, the POC is arranged at the rear end inside the catalytic converter body and is near the smoke exhaust port, a plurality of smoke passing passageways are arranged inside the POC in a clamping mode and are distributed in a radial shape from the axis center of the POC, and the width of each smoke passing passage is gradually increased from inside to outside. The catalytic converter based on the radial POC structure is simple in structure, is novel in design, adopts the POC structure with the smoke passing passages which are distributed in the radial shape, and enables air flow to evenly enter the POC for reaction, thereby improving the efficiency of catalytic reactions and effectively preventing the POC from being burnt out.
Description
Technical field
The utility model relates to low-emission technology field, relates in particular to a kind of catalyst converter based on radial POC structure.
Background technique
Automobile catalytic device is for the exhaust-gas treatment system of explosive motor (including, but not limited to petrol engine or diesel engine).Automobile catalytic device generally comprises DOC(oxy－catalytic scrubber) and POC(particulate oxidation purifier).DOC can be oxidized the harmful gases such as CO, HC in exhaust, POC can remove in exhaust carbon soot particles, thereby reduce the discharge of harmful gas.
POC, when carrying out carbon soot particles trapping, due to factors such as burning is insufficient, the accumulations of sulphate composition, can cause runner to stop up, and air-flow cannot normally be passed through, and causes the unfavorable factors such as exhaust back pressure raises, the increase of row's temperature, finally causes POC sintering to damage.Meanwhile, according to the air-flow regularity of distribution, air-flow velocity successively decreases toward both sides from middle, and it is inhomogeneous to cause air-flow to enter the flow velocity of POC, causes reaction balanced, thereby greatly reduces the catalytic efficiency of POC.
Model utility content
In order to solve above technical problem, the purpose of this utility model is to provide a kind of and can makes air-flow evenly enter POC to react to improve catalytic efficiency, with the automotive exhaust catalysis device that can be able to effectively avoid POC sintering to damage.
Complete skill scheme of the present utility model is: a kind of catalyst converter based on radial POC structure, comprising: catalyst converter body, DOC and POC.
Described catalyst converter body front end is provided with into mouth, and rear end is provided with smoke exhaust port.
Described DOC is arranged at catalyst converter body interior front end near entering mouth place.
Described POC is arranged at catalyst converter body interior rear end near smoke exhaust port place.
In described POC, be folded with some logical plumes road.
Described logical plume road is outwards distributed radially by the place, axle center of POC, and the width in logical plume road increases from inside to outside gradually.
The utility model compared with prior art has following beneficial effect:
The utility model provides a kind of catalyst converter based on radial POC structure, because logical plume road increases from inside to outside gradually according to the axle center of POC, the resistance running into that air-flow enters POC reduces from inside to outside gradually, make air-flow can enter uniformly POC reaction, thereby improve the efficiency of catalytic reaction.Because the logical cigarette width of flow path of periphery is larger, when soot and sulphate overheap, while resulting in blockage, can from the logical plume road of periphery, flow away by guide portion gas simultaneously, thereby avoid POC sintering to damage.The utility model is simple in structure, and modern design adopts DOC+POC structure, is widely used, and preparation process is simple, and arresting efficiency is high, and system is ripe, is easy to promote on a large scale.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation, and in figure, arrow is exhaust airstream direction;
Fig. 2 is that the utility model POC A of place is to sectional view.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
The present embodiment
The present embodiment provides a kind of catalyst converter based on radial POC structure, and structure, as shown in Fig. 1 and Fig. 2, comprising: comprising: catalyst converter body 1, DOC2 and POC3; Described catalyst converter body 1 front end is provided with into mouth 4, and rear end is provided with smoke exhaust port 5; Described DOC2 is arranged at catalyst converter body 1 interior forward end near entering mouth 4 places; Described POC3 is arranged at the inner rear end of catalyst converter body 1 near smoke exhaust port 5 places; In described POC3, be folded with some logical plumes road 6; Described logical plume road 6 is outwards distributed radially by the place, axle center of POC, and the width in logical plume road 6 increases from inside to outside gradually.
The present embodiment is due to logical plume road 6 is increased from inside to outside gradually according to the axle center of POC3, and the resistance running into that air-flow enters POC3 reduces from inside to outside gradually, makes air-flow can enter uniformly POC3 reaction, thereby improves the efficiency of catalytic reaction.Because logical plume road 6 width of periphery are larger, when soot and sulphate overheap, while resulting in blockage, can from the logical plume road 6 of periphery, flow away by guide portion gas simultaneously, thereby avoid POC3 sintering to damage.
The technological scheme above the utility model embodiment being provided is described in detail, applied specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation is only applicable to help to understand the utility model embodiment's principle; , for one of ordinary skill in the art, according to the utility model embodiment, in embodiment and application area, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
