Abstract
The utility model relates to the technical field of exhaust purification, and discloses a catalytic converter with a POC bypass flue. The catalytic converter with the POC bypass flue comprises a catalytic converter body, a DOC, a POC and the POC bypass flue, wherein a smoke inlet is formed in the front end of the catalytic converter body, a smoke outlet is formed in the rear end of the catalytic converter body, the DOC is arranged at the position, close to the smoke inlet, of the front end inside the catalytic converter body, the POC is arranged at the position, close to the smoke outlet, of the rear end inside the catalytic converter body, and the POC bypass flue is arranged between the POC and the inner wall of the catalytic converter body. The catalytic converter with the POC bypass flue is simple in structure and novel in design, when much carbon black and sulfate are accumulated in a POC flow pass and the POC flow pass is blocked, the POC bypass flue can guide part of gas to flow away from the bypass flue, and the POC is effectively prevented from being sintered and damaged.
Description
Technical field
The utility model relates to low-emission technology field, relates in particular to a kind of catalyst converter with POC bypass flue.
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.
Existing automobile catalytic device POC is 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, cause the unfavorable factors such as exhaust back pressure raises, the increase of row's temperature, finally cause POC sintering to damage.
Model utility content
In order to solve above technical problem, the purpose of this utility model is to provide a kind of automotive exhaust catalysis device that can effectively avoid POC sintering to damage.
Complete skill scheme of the present utility model is: a kind of catalyst converter with POC bypass flue, comprising: catalyst converter body, DOC, POC and POC bypass flue.
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.
Between described POC and catalyst converter inner body wall, be provided with POC bypass flue.
The utility model compared with prior art has following beneficial effect:
The utility model provides a kind of catalyst converter with POC bypass flue, simple in structure, modern design, the overheap in POC runner when soot and sulphate, while causing POC runner to stop up, POC bypass flue can flow away from bypass flue by guide portion gas, effectively avoids POC sintering to damage.
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 with POC bypass flue, and structure, as shown in Fig. 1 and Fig. 2, comprising: catalyst converter body 1, DOC2, POC3 and POC bypass flue 4; Described catalyst converter body 1 front end is provided with into mouth 5, and rear end is provided with smoke exhaust port 6; Described DOC2 is arranged at catalyst converter body 1 interior forward end near entering mouth 5 places; Described POC3 is arranged at the inner rear end of catalyst converter body 1 near smoke exhaust port 6 places; Between described POC3 and catalyst converter body 1 inwall, be provided with POC bypass flue 4.
The overheap in POC3 runner when soot and sulphate, while causing POC3 runner to stop up, POC bypass flue 4 can flow away by guide portion gas, thereby effectively avoids 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.
