Abstract

The utility model discloses a catalyst carrier structure of exhaust gas emission. The catalyst carrier structure of the exhaust gas emission comprises a columnar shell body and a core body in the shell body. The catalyst carrier structure of the exhaust gas emission is characterized in that the core body comprises a first level core body and a second level core body, an interval cavity is arranged between the two levels of core body, and each level core body is formed by crossing overlapping of a plurality circles of alloy plate sheets and a plurality circles of alloy ripple sheets from inside to outside in the circumferential direction. As an optimization, the length of the interval cavity between the two levels of the core bodies is 5 mm to 10 mm. The catalyst carrier structure of the exhaust gas emission prolongs residence time of tail gas staying in a metal carrier, improves transforming efficiency, optimizes producing process of the metal carrier, reduces welding process of welding a three-way catalyst in a muffler factory, and improves producing efficiency of a processing enterprise. Thus, the catalyst carrier structure of the exhaust gas emission has the advantages of being simple in structure, low in cost, high in transforming efficiency, high in processing efficiency, and the like.

Description

A kind of exhaust emissions catalyst support structures
Technical field
The utility model relates to a kind of automotive emission catalytic convention design, especially a kind of exhaust emissions catalyst support structures.
Background technique
Usually adopt the exhaust emissions catalytic converter of in tail gas discharging pipe, packing into petrol engine as the automobile of power, the purification of motorcycle exhaust, it comprises housing, catalyst carrier substantially, catalyst carrier constitutes the porous core body that tail gas can pass through smoothly, is stained with the three-way catalyst of platinum, palladium, three kinds of precious metals compositions of rhodium at core body.When tail gas passes through catalyst carrier, contact with three-way catalyst, wherein the harmful gases such as carbon monoxide, hydrocarbon, oxynitrides are converted into innocuous gas under the three-way catalyst effect, reach discharging standards.
In motorcycle state III initial stage, the normal scheme that adopts the two-stage catalyzer to add Carburetor in the prior art, the two-stage catalyst support structures is the stand-alone product of making separately, the harmful gas of manufacture cycle lengthening, cost height, the welding process that increases silencing apparatus producer, motorcycle emission and the time of contact of catalyzer are shorter, are unfavorable for that catalyzer is to the conversion of harmful gas.
The model utility content
For above-mentioned deficiency, technical problem to be solved in the utility model is, how to provide a kind of simple in structure, with low cost, can improve transformation efficiency, improves the exhaust emissions catalyst support structures of work efficiency.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model.
A kind of exhaust emissions catalyst support structures, comprise the core body in columnar housing and the housing, it is characterized in that, described core body comprises first order core body and second level core body, be provided with spaced cavities between the two-stage core body, every grade of core body by multi-turn alloy sheets shape thin slice and multi-turn alloy corrugated thin slice week upwards from inside to outside juxtaposition form.As optimization, the spaced cavities length between the described two-stage core body is 5-10mm.
In the utility model, adopt the hollow metal carrier, be about to the interval that the two-stage core body is arranged in the housing and middle empty 5-10mm forms for buffering and be beneficial to tail gas by catalysis, so just allow two catalyzer become a catalyzer, effectively simplify the structure, reduced leftover pieces waste, make the manufacture cycle shorten for 1/3rd time, make at least silencing apparatus producer lack the twice welding processs, improved the manufacturing efficiency of silencing apparatus enterprise.
As further optimization, every circle alloy corrugated thin slice by alloy plate thin slice embossing shape after the volume be that cylindrical shape obtains, the ripple form of fracture is trigonometric form, just hexagonal or positive square.Like this, can Effective Raise tail gas and catalyzer area of contact, improve treatment effect, possess simultaneously simple advantage easy to make.
In sum, the utility model improves tail gas holdup time in metallic carrier, has improved transformation efficiency, has optimized the metallic carrier production technology, reduces the welding process of silencing apparatus factory when the welding three-way catalyst, has improved the manufacturing efficiency of processing enterprise.So have simple in structurely, with low cost, transformation efficiency is high, the work efficiency advantages of higher.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During implementation, as depicted in figs. 1 and 2, a kind of exhaust emissions catalyst support structures, comprise the core body in columnar housing 3 and the housing, described core body comprises first order core body 1 and second level core body 2, be provided with spaced cavities 4 between the two-stage core body, juxtaposition forms every grade of core body making progress in week from inside to outside with multi-turn alloy corrugated thin slice 6 by multi-turn alloy sheets shape thin slice 5.Spaced cavities 4 length between the described two-stage core body are 5-10mm.
In addition, during implementation, every circle alloy corrugated thin slice by alloy plate thin slice embossing shape after volume be that cylindrical shape obtains, the ripple form of fracture can be the forms such as trigonometric form, just hexagonal or positive square.
