Abstract
The utility model discloses a nitrogen and oxygen purifier for an automobile. The nitrogen and oxygen purifier comprises carriers gathered into a silk screen ball-shaped structure, wherein an alumina layer, a rear earth layer, a platinum layer, a palladium layer and a rhodium layer are sequentially wrapped outside the carrier. The nitrogen and oxygen purifier for the automobile is low in cost, convenient to use, and capable of effectively catalyzing hydrocarbon, carbon monoxide and nitric oxide in tail gas of the automobile to purify the tail gas of the automobile.
Description
Technical field
The present invention relates to a kind of automobile nitrogen oxygen purifier.
Background technique
During the motor car engine running, participate in the mixed gas possibility incomplete combustion of burning in the oil-burning internal combustion engine, the waste gas of discharging contains hydrocarbon, carbon monoxide, nitrogen oxide etc., causes environmental pollution, has affected health.Therefore installed ternary catalyzing unit additional on the existing automobile, the gases such as ternary catalyzing unit can catalytic hydrocarbon, carbon monoxide, nitrogen oxide carry out redox reaction, make the dusty gas of motor vehicle exhaust emission be converted into innocuous gas.Yet automobile three-way catalysts is not long working life, domestic ten thousand kilometers of the 5-8 that are generally, and above the ternary catalyzing unit in working life, the function of cleaning of off-gas can weaken even lose efficacy at double.
For the phenomenon of exceeding the time limit, losing efficacy or causing automobile three-way catalysts to poison or stop up because oil product is poor, usually adopt the method for changing ternary catalyzing unit to solve.But what the catalyzer in the automobile three-way catalysts adopted is precious metal material, and cost is higher, and the market price is expensive, and the user is difficult to accept.
The model utility content
The model utility purpose: the purpose of this utility model provides the automobile nitrogen oxygen purifier that a kind of cost is low, catalytic efficiency is high.
Technological scheme: the utility model provides automobile nitrogen oxygen purifier, comprises the carrier that gathers into the silk screen spheroidal structure, is enclosed with successively alumina layer, rare earth layer, platinum layer, palladium layer and rhodium layer in the outside of carrier.
This automobile nitrogen oxygen purifier is the silk screen spheroidal structure, geometric area is large, the noble metal catalyst coated side is large, therefore tail gas is large with the catalyzer area of contact, the effectively hydrocarbon in the catalytic car tail-gas, carbon monoxide, nitrogen oxide etc., catalytic efficiency height.
The preparation method of this automobile nitrogen oxygen purifier adopts under the high-temperature roasting condition coating alumina outside carrier, leaves standstill cooling, adopts the method to apply successively rare earth, platinum, palladium and rhodium again; Make this automobile nitrogen oxygen purifier through repeated calcination.
As a kind of improvement of technical solutions of the utility model, described carrier is the cylinder that a tangent plane and an arc surface form, and described carrier is the internal spiral structure at its bearing of trend; Thereby tail gas is advanced along snail, increased the area of contact of tail gas and catalyzer, reduced the efflux time in ternary catalyzing unit, make the catalysis of tail gas more fully, improve the tail gas clean-up effect.
Described carrier is Stainless Steel Wire, and Stainless Steel Wire carrier specific surface area is large, mechanical strength is high, corrosion resistance is strong, thermal expansion coefficient is low, thermal-shock resistance is strong, has not only reduced cost of production, and durability that can this automobile nitrogen oxygen purifier of Effective Raise.
Described rare earth is the commercially available prod.
A kind of preferred as the technical program, described rare earth be the strong rare earth metal of activity.
During use, the automobile nitrogen oxygen purifier that the utility model provides is put into automobile three-way catalysts, can place as required one or more automobile nitrogen VPO catalysts; Behind the car engine, heat of engine can conduct to rapidly on the nitrogen oxygen purifier, produces fast catalysis.
Beneficial effect: the automobile nitrogen oxygen purifier cost that the utility model provides is low, easy to use, effectively hydrocarbon, carbon monoxide, nitrogen oxide in the catalytic car tail-gas, purifying automobile tail gas.
After using the car engine of this automobile nitrogen oxygen purifier, heat of engine can conduct to rapidly on the carrier, produces fast catalysis; Thereby carrier is the internal spiral structure at its bearing of trend makes tail gas advance along snail, has increased the area of contact of tail gas and catalyzer, has reduced the efflux time in ternary catalyzing unit, makes the catalysis of tail gas more fully, improves the tail gas clean-up effect; It is good that this automobile nitrogen oxygen purifier is crossed gas, indeformable under the high-temperature condition, do not rupture, and do not fall bits.
