Description
[technical field]
The utility model relates to a kind of catalyst converter carrier, and specifically the utility model relates to a kind of three-way catalytic converter carrier.
[background technique]
Known, ternary catalyzing unit, be mounted in most important outer purifier in automobile exhaust system, it can by vehicle exhaust discharge the harmful gas such as CO, HC and NOx by with catalyst converter grid on noble coatings produce oxidation and reduction, thereby change harmless carbon dioxide, water and nitrogen into, vehicle exhaust is purified; Tail-gas from gasoline automobiles pollutes day by day serious, if the contained harmful matter of the particle that swims in tail gas is sucked lung by people for a long time and will directly jeopardize people's health, along with the increase of people's environmental consciousness, the pollution that how to reduce vehicle exhaust has become the problem of everybody growing interest.
The most frequently used three-way catalytic converter carrier is all that even order is counted catalyst converter at present, there are two kinds of 400CPSI and 600CPSI, geometrical shape also mostly adopts grid type, how to make vehicle exhaust evenly carry out chemical reaction by grid to greatest extent, is the key that determines three-way catalytic converter carrier Processing capacity, by reference to the accompanying drawings shown in 1, in accompanying drawing 1, the surface of this structure inlet end A2 is plane, in the time that tail gas air-flow enters the inlet end A2 of carrier 3, a large amount of tail gas air-flows can be introduced into the middle part pore of inlet end A2, the temperature that concentrates on carrier 3 middle part pores cannot be left, under long term high temperature, can first cause coming off and losing the function that is oxidized and reduces harmful gas at the precious metal of carrier 3 middle part pores, and the part that middle part air-flow the produces air-flow that is obstructed flows into the periphery pore of inlet end A2, thereby cause the area of contact of air-flow and carrier 3 periphery pores less, increase with the area of contact of middle part pore, air-flow is not maximized the use by the space of carrier 3.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses a kind of three-way catalytic converter carrier, the arc shaped surface that described three-way catalytic converter carrier is set to cave inward by the middle part of carrier inlet end B, the limit portion of inlet end B is plane, the air inlet distance that makes vehicle exhaust enter inlet end B surface equates, impel vehicle exhaust can enter uniformly in the grid of carrier, the utility model is because vehicle exhaust can be uniformly by the grid of carrier, the area of contact of vehicle exhaust and carrier periphery grid is increased, not only improve the chemical reaction ability of noble coatings and vehicle exhaust, and effectively improve gas purification coefficiency, thereby extend the working life of carrier.
For achieving the above object, the utility model adopts following technological scheme:
A kind of three-way catalytic converter carrier, comprise ternary catalyzing unit housing and carrier, inside at ternary catalyzing unit housing is provided with carrier, the middle part of described carrier inlet end B is the arc shaped surface caving inward, the limit portion of inlet end B is plane, be equipped with catalyst coat on the surface of carrier inlet end B and the inner face of carrier, between described ternary catalyzing unit housing and carrier, be provided with ceramic fiber liner.
Described three-way catalytic converter carrier, described catalyst coat is the mixture of precious metal and rare earth elements.
Described three-way catalytic converter carrier, described precious metal is the combined solution of platinum, palladium, rhodium.
Described three-way catalytic converter carrier, described liner is mesh pad.
Owing to having adopted technique scheme, the utlity model has following superiority:
The arc shaped surface that three-way catalytic converter carrier described in the utility model is set to cave inward by the middle part of carrier inlet end B, the limit portion of inlet end B is plane, the air inlet distance that makes vehicle exhaust enter inlet end B surface equates, impel vehicle exhaust can enter uniformly in the grid of carrier, the utility model is because vehicle exhaust can be uniformly by the grid of carrier, the area of contact of vehicle exhaust and carrier periphery grid is increased, not only improve the chemical reaction ability of noble coatings and vehicle exhaust, and effectively improve gas purification coefficiency, thereby extend the working life of carrier.

[embodiment]
Can explain in more detail the utility model by the following examples, the utility model is not limited to the following examples;
A kind of three-way catalytic converter carrier described in by reference to the accompanying drawings-accompanying drawing 4, comprise ternary catalyzing unit housing 1 and carrier 3, be provided with carrier 3 in the inside of ternary catalyzing unit housing 1, the middle part of described carrier 3 inlet end B5 is the arc shaped surface caving inward, the limit portion of inlet end B5 is plane, be equipped with catalyst coat on the surface of carrier 3 inlet end B5 and the inner face of carrier 3, described catalyst coat is the mixture of precious metal and rare earth elements; Described precious metal is the combined solution of platinum, palladium, rhodium; Between described ternary catalyzing unit housing 1 and carrier 3, be provided with ceramic fiber liner 4; Described liner 4 is mesh pad.
Implement three-way catalytic converter carrier described in the utility model, in use, the arc shaped surface that is set to cave inward due to the middle part of carrier 3 inlet end B5, the limit portion of inlet end B5 is plane, the air inlet distance that makes vehicle exhaust enter inlet end B5 surface equates, impel vehicle exhaust can enter uniformly in the grid of carrier 3, avoid tail gas to focus in a large number the center portion of carrier 3, the temperature in carrier 3 center portions cannot be left, and the drawback that causes noble coatings to come off, between ternary catalyzing unit housing 1 and carrier 3, liner 4 is set, there is sealing, heat insulation and cushion effect, because the variation of delivery temperature is larger, the hot expansibility of ternary catalyzing unit housing 1 and carrier 3 differs larger, ceramic fiber liner 4 is set or mesh pad liner 4 all has good sealability, while preventing exhaust between ternary catalyzing unit housing 1 and carrier 3 reveal, also can prevent that carrier 3 from being impacted and damaging, can also effectively prevent that the high temperature of carrier 3 from passing to housing, the utility model is because vehicle exhaust can pass through the grid of carrier 3 uniformly, the area of contact of vehicle exhaust and carrier 3 periphery grids is increased, not only improve the chemical reaction ability of noble coatings and vehicle exhaust, and effectively improve gas purification coefficiency, thereby extended the working life of carrier 3.
The utility model does not describe part in detail for prior art.
The embodiment who selects in this article for open goal of the invention of the present utility model, currently thinks suitablely, still, will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the embodiment within the scope of this design and model utility.
