Description
Technical field
This utility model is related to automobile exhaust purification equipment technical field, more particularly to a kind of purifying vehicle exhaust catalysis
Device.
Background technology
With the fast development of social economy and city process, people's living standard is improved constantly, to go out it is accommodating,
It is quick to require also more and more higher with comfortable.Automobile is going into family, vehicle exhaust as a kind of vehicles of modernization
Pollution problem also become current social urgent problem.
At present, automaker is that the national standard for reaching the discharge of vapour tail-gas would generally be installed additional in vehicle exhaust exit
Automobile exhaust purifier.The operation principle of automobile exhaust purifier is to allow tail gas by being supported with the cellular of noble metal catalyst
Reacted using pyro-oxidation-reduction during carrier and nitrogen oxides not sufficiently combusted in tail gas, carbon monoxide and Hydrocarbon are dropped
Solution is into nontoxic nitrogen, carbon dioxide and water.However, current automobile exhaust purifier still can not completely by dusty gass
Change into innocuous gas, it is therefore necessary to further improve the transformation efficiency of vehicle exhaust, mitigate the pollution to air, and,
It is encapsulated in the core body of existing catalyst converter in housing more and can not takes out, cause cleaning to be difficult, affects the service life of catalyst converter.
Utility model content
To overcome above-mentioned deficiency, the invention provides a kind of easy to clean, long service life and the high automobile of transformation efficiency
Exhaust purification catalytic device.
The technical solution adopted in the utility model is：A kind of purifying vehicle exhaust catalyst converter, including housing, are arranged on housing
The air inlet pipe and exhaustor at two ends, is arranged on the heat-insulating and shock-absorbing layer of shell skin, and the shell portion of the housing is by three cylinders
Circle is formed by connecting, and the two ends of the cylindrical enclosure are respectively arranged with fixing device, the fixing device of two adjacent cylindrical enclosures
On be fixed with catalyst carrier, catalyst is provided with the catalyst carrier, the catalyst carrier includes honeycomb metal
Carrier and SiC foam ceramic monolith.
Used as the further setting of such scheme, the metallic honeycomb substrate and SiC foam ceramic monolith are respectively by phase
Fixing device on adjacent two cylindrical enclosures is fixed.
Used as the further setting of such scheme, the honeycomb of the metallic honeycomb substrate is corrugated, described for ripple
The material of stricture of vagina shape piece is alloy thin band.
As the further setting of such scheme, in the outer corresponding fixing device of the housing, screw, the phase are provided with
It is spirally connected connection by bolt-through screw between two adjacent cylindrical enclosures.
As the further setting of such scheme, soft damping between the catalyst carrier and fixing device, is filled with
Thing.
The beneficial effects of the utility model are as follows：
1st, cylinder is constituted by three cylindrical enclosure splicings, convenient to dismantle, easy cleaning increases the service life of catalyst converter；
2nd, the complex carries of metallic honeycomb substrate and SiC foam ceramic monolith are arranged, and are enhanced the conversion ratio of catalyst converter, are carried
High clean-up effect.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
In figure：1st, housing；2nd, air inlet pipe；3rd, exhaustor；4th, heat-insulating and shock-absorbing layer；5th, cylindrical enclosure；6th, fixing device；7th, it is catalyzed
Agent carrier；71st, metallic honeycomb substrate；72nd, SiC foam ceramic monolith.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the present invention.
As shown in figure 1, a kind of purifying vehicle exhaust catalyst converter, including housing 1, it is arranged on 2 He of air inlet pipe at 1 two ends of housing
Exhaustor 3, is arranged on the heat-insulating and shock-absorbing layer 4 on 1 top layer of housing, the shell portion of the housing 1 connected by three cylindrical enclosures 5 and
Into the two ends of the cylindrical enclosure 5 are respectively arranged with fixing device 6, solid in the fixing device 6 of two adjacent cylindrical enclosures 5
Surely there is catalyst carrier 7, in the catalyst carrier 7, be provided with catalyst, the catalyst carrier 7 includes that honeycomb metal is carried
Body 71 and SiC foam ceramic monolith 72；The metallic honeycomb substrate 71 and SiC foam ceramic monolith 72 are respectively by two neighboring
Fixing device 6 on cylindrical enclosure 5 is fixed；The honeycomb of the metallic honeycomb substrate 71 is corrugated, described for corrugated
Material be alloy thin band；Screw, two adjacent cylindrical enclosures 5 are provided with 1 outer corresponding fixing device 6 of the housing
Between be spirally connected connection by bolt-through screw；Soft damping thing is filled between the catalyst carrier 7 and fixing device 6.
In this utility model, housing 1 is formed by connecting by three cylindrical enclosures 5, and catalyst carrier 7 is arranged at two cylinders
In the middle of circle 5, the dismounting and cleaning of catalyst converter are facilitated, the service life of ternary catalyzing unit is improve；
Metallic honeycomb substrate 71 and 72 complex carries of SiC foam ceramic monolith are arranged, and are enhanced the conversion ratio of catalyst converter, are carried
High clean-up effect, metallic carrier geometry specific surface area, percent opening are high than ceramic monolith, are conducive to catalyst activity material
Adsorb and reduce exhaust resistance；Additionally, the metallic carrier coefficient of heat conduction, thermal coefficient of expansion are also above general ceramic material, can be with
Good thermal expansion matching is realized with the housing 1 of catalyst converter, and ratio of heat capacities ceramic monolith is low, can be shortened and reach catalysis instead
Answer the time of temperature；Mechanical strength, can avoid the secondary pollution caused because of catalyst breakage.
