Description
Technical field
The present invention relates to a kind of catalyst converters, and in particular to a kind of automobile speed-raising energy-saving and purifying catalyst converter.
Background technique
The continuous high speed development of modern industry, makes energy and environment have become countries in the world today focus of attention.Especially
It is that in recent years, oil price fluctuation is larger, the continuous growth of energy demand allows the awareness of saving energy of people to be gradually increased, and the world is each
Government, state seeks various means and improves energy utilization rate.Automobile is greatly changed as the important vehicles that people go on a journey
Human life style promotes the progress of human society.People are while enjoyment modernization offers convenience, daily life
Exempt from customs examination environment does not bring harm, the haze weather strong influence that the proximal segment time frequently occurs in China the north, middle part
The daily life and human health of resident.Now worldwide car ownership is more than 700,000,000, the year production and marketing of China's automobile
Amount also break through 20,000,000, while facilitating people to go on a journey, bring energy consumption, pollution environment the problem of also can not be ignored.
National governments all put into effect severe statutory standard, urge Automobile Enterprises exploitation more energy-efficient and the automobile of low emission.
Organic matter fuel used in automobile engine in the combustion chamber completely burned when, if not considering a little impurity therein
If, only generate carbon dioxide and water.However, when engine operation, is extremely difficult to fuel completely burned in actual use
Condition, higher revolving speed can make fuel very short with air contact time, often be unable to substantially uniformity mixing, when for hypoxgia,
High temperature and high pressure environment makes fuel that cracking, dehydrogenation occur, to generate CO, HC, NOXEqual pernicious gases.
By catalytic action by vehicle exhaust hydro carbons and Oxidation of Carbon Monoxide be that the catalyst of carbon dioxide and water leads to
Frequently referred to automobile oxidation catalyst (DOC) or catalytic cleaner, are mounted in automobile engine exhaust pipe.When the automobile of high temperature
When tail gas passes through catalytic cleaner, the catalyst in catalytic cleaner will enhance the activity of tri- kinds of gas of CO, HC and NOx, promote
It carries out certain oxidationreduction chemical reaction, and wherein CO is oxidized into colourless, nontoxic carbon dioxide gas at high temperature；
HC compound is oxidized to water (H20) and carbon dioxide at high temperature；NOx is reduced into nitrogen and oxygen；Three kinds of pernicious gases become
Innocuous gas makes vehicle exhaust be purified.
After study, the principal element for influencing car tail-gas catalytic purifier working efficiency includes two o'clock: 1) being coated in vapour
The catalytic efficiency of catalyst coat on tail gas catalytic cleaner；2) when tail gas passes through catalytic cleaner and catalyst coat
The area and reaction timeliness of contact.
Had some researchs about purifying vehicle exhaust catalyst converter at present, such as Publication No.: CN107620619A is public
A kind of exhaust gas cleaner using perovskite-based catalyst is opened, which is by air inlet, exhaust outlet and tail gas clean-up
Portion's composition, which is characterized in that tail gas clean-up portion is the hollow circuit cylinder that internal diameter is 24cm, in the tail gas clean-up portion described in
Air inlet to exhaust outlet direction is disposed with high-tension circuit, double wire nettings, oil mist filter screen and catalyst carrier, the dress
It sets and further tail gas is catalyzed before exhaust emissions using perovskite-based three-way catalyst by the way that catalyst carrier is arranged
Conversion, by CO, HC, NOXIt aoxidizes respectively, be reduced to the carbon dioxide being harmful to human health, nitrogen and vapor, to make
The tail gas that exhaust gas cleaner discharge must be eventually passed through is the gas that atmosphere pollution is obviously reduced, but the apparatus structure is multiple
It is miscellaneous, and due to tail gas using directly enter directly go out by the way of contact with catalyst carrier, contact area is small, it is low to react timeliness, and
That there are high temperature actives is poor for the perovskite-based three-way catalyst used, thermal stability also poor problem.
Summary of the invention
In view of the deficiencies of the prior art, the invention proposes a kind of automobile speed-raising energy-saving and purifying catalyst converters, by mentioning simultaneously
High exhaust gas and catalyst contact area react timeliness and improve the mode of catalyst efficiency, effectively improve vehicle exhaust
Middle CO, HC, NOXThe purification efficiency of equal pernicious gases.
To realize above-mentioned technical proposal, a kind of automobile speed-raising energy-saving and purifying catalyst converter provided by the invention, comprising: inlet end
Lid, strong magnet, spring, catalyst carrier Water conservancy diversion core, diversion shell and outlet end cap, the outlet end cap are mounted on blower inlet casing
The bottom of body, catalyst carrier Water conservancy diversion core are socketed in diversion shell, and spring is mounted on the top of catalyst carrier Water conservancy diversion core,
Strong magnet is mounted on the top of spring, and strong magnet, which is provided centrally with, covers the through-hole that air inlet pipe matches, inlet end with inlet end
Lid is mounted on the top of diversion shell after covering strong magnet, be uniformly provided in multilayer in the catalyst carrier Water conservancy diversion core
The lower deflector hole group being stacked that misplaces, every layer of deflector hole group are made of the deflector hole of multiple circumferentially array distributions, each
Deflector hole includes air inlet taper hole, split channel hole and outlet taper hole, the air inlet taper hole be set as from gas flow direction by
Tapered outside to inside, outlet taper hole is set as from gas flow direction flaring from inside to outside, and split channel hole is for connecting inlet cone
Hole and outlet taper hole, and the outlet taper hole in the single deflector hole in the deflector hole group of upper layer and four in lower layer's deflector hole group
Air inlet taper hole in a deflector hole mutually overlaps, and catalyst filling carrier in the split channel hole, the catalyst carrier is every
300~400 holes are opened up on square inch, average pore size is 15~30μThe metal beehive carrier of m, catalyst are coated in the gold
Belong on honeycomb substrate, the metal beehive carrier of the coating catalyst is made by the following method: S1, being by weight percent
2%~7% aluminium oxide Al2O3, 32%~45% cerium oxide CeO2, 10%~15% calcium oxide CaO, 12%~18%
Lanthana La2O3, 13%~22% titanium oxide TiO2, 5%~8% copper oxide CuO, 11%~18%ZnO and 200%~
400% deionized water is uniformly mixed, and forms slurries；S2, slurries obtained in abrading-ball processing step S1, control are used
Granularity D90 is less than 3 μm；S3, it is evaporated the moisture in mixed liquor obtained by step S2 to obtain solid powder using rotary evaporator
Then end roasts 3~5h at 600~700 DEG C, obtains primary coat object；S4, by weight takes 85~95 parts of step S4 preparations
