Abstract
The utility model relates to the technical field of a three-way catalytic converter for purifying tail gas of automobiles, in particular to a metal carrier of a three-way catalytic converter, which solves the prior technical problems that the technical design is not reasonable and the like. The metal carrier of the three-way catalytic converter comprises a cylindrical shell body and a core body arranged in the shell body, and is characterized in that the core body comprises a plurality of parallel plate bodies at equal intervals, a waved bent plate is arranged between the adjacent plate bodies. Compared with the prior art, the metal carrier of the three-way catalytic converter has advantages of reasonable design, simple structure, long service life, low cost and stable working performance.
Description
Technical field
The utility model relates to motor vehicle tail-gas purifying with three-element catalytic reforming unit technical field, especially relates to a kind of three-way catalytic converter metallic carrier.
Background technique
Usually be employed in the ternary catalyst purifier of packing in the tail gas discharging pipe with petrol engine as the automobile of power, the purification of motorcycle exhaust; Its basic comprising is the porous core body that tail gas can pass through smoothly; On core body, be stained with the three-way catalyst of platinum, palladium, three kinds of precious metals compositions of rhodium, this porous core body is catalyst carrier.When tail gas passes through catalyst carrier, contact with three-way catalyst, wherein harmful gases such as carbon monoxide, hydrocarbon, nitrogen oxide form innocuous gas under the catalysis of three-way catalyst, reach the emission standard of permission.At the ternary catalyst purifier initial stage of development; Core body generally adopts porous ceramic bodies to process, and is the ceramic monolith of three-way catalyst, but because its mechanical strength; High-temperature behavior etc.; Limited the raising of working life and purifying effect, be about 2 years its working life, and automobile effectively purifies 50,000 kilometers of strokes.Now external most of manufacturers adopt the particular alloy thin slice to be rolled into the metallic carrier of multicolumn body as three-way catalyst; For tail gas can be passed through smoothly; And can adhere to three-way catalyst preferably, and general strike out alloy sheet earlier corrugatedly, the planar alloy sheet of every corrugated alloy sheet and same material is superimposed together; Be rolled into the multilayer cylinder again; From cross section, can see that the structure of metallic carrier is the porous road structure that one deck corrugated thin slice and one deck flat sheet are asked formation mutually from the center to the skin, the ripple height of corrugated thin slice is 2.5-5mm, effectively purifies stroke and can reach 100,000 kilometers.
But discover that at the ternary catalyst purifier duration of work, three-way catalyst can split away off from metallic carrier, has reduced the effective dose of three-way catalyst, influenced the purifying effect and the working life of ternary catalyst purifier significantly.For this reason, people have carried out long-term exploration, have proposed various solutions.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, is easy to manufacturing, and cost of production is lower, the three-way catalytic converter metallic carrier of long service life.
For achieving the above object; The utility model has adopted following technical proposal: this three-way catalytic converter metallic carrier; The housing and the core body that is arranged in the housing that comprise cylinder; It is characterized in that described core body comprises some being arranged in parallel and the plate body of spaced set, is provided with the folded plate of bending undulate between the two adjacent plate bodys.
In above-mentioned three-way catalytic converter metallic carrier, the thickness of described plate body is greater than the thickness of folded plate.
In above-mentioned three-way catalytic converter metallic carrier, described folded plate thickness is 0.05-0.1mm; The thickness of described plate body is 0.1-0.2mm.
Compared with prior art, the advantage of this three-way catalytic converter metallic carrier is: reasonable in design, simple in structure, and long service life, the manufacturing cost is lower, good operating stability.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, housing 1, core body 2, plate body 21, folded plate 22.
Embodiment
