Abstract
A low-temperature catalytic oxidation purifier for vehicle exhaust comprises an inlet tube, an outlet tube, a base material and a catalytic transforming unit. The base material comprises an inner tube and an outer tube which is covered to integration, one end of the base material is connected to the air inlet tube, and the other end is connected to the discharge tube. The catalytic transforming unit is fixed in the base material by the clamping unit, and the catalytic transforming unit is made up of wounding and lamination of wire screen. The Platinum mesh material is the 0CrNi19 steel wire with 0.1 to 2 mm, and coated with Platinum (Pt), Rhodium (Rh) and Palladium (Pd) is coated on the mesh screen by plaza screening.
Description
Affiliated technical field
The utility model relates to a kind of automobile exhaust purifier, particularly diesel locomotive low-temp tail gas catalyzing, oxidizing and purifying device.
Background technique
As everyone knows, carbon monoxide in diesel engine vent gas (CO), hydrocarbon (HC), oxynitrides (NOx), particle (PT) harmful matter are by the time greatly threatening existent environment of people, people begin this has been given the attention of height for this reason, are intended to address this problem.
At present, it is also few that China is used for the device of diesel engine of vehicle tail gas clean-up, a kind of like this purification plant is disclosed in D.B.P. (GB2298147Device for treating exhaust gases), it is made up of inside and outside two tubes that are nested together, and is provided with metallic catalyst between inner/outer tube.Chinese patent (the comprehensive purification plant of ZL02227045.0 diesel engine truck exhaust) discloses a kind of like this device, and it is interconnected by heater, secondary air feeder, thermal reaction chamber and catalytic converter forms.Also having some on the market is the purification plant of carrier with the ceramic particle.Generally speaking, the complex structure of these devices, effect is not fine, and particularly the discharging of homemade diesel engine itself is poor, and the particle in the waste gas very easily stops up catalytic converter, and external purification plant can not satisfy the actual demand of China.
Summary of the invention
The utility model is exactly the defective that exists in the above-mentioned prior art in order to overcome, and a kind of simple and reasonable exhaust gas cleaner is provided, and the oxious component of discharging tail gas is reduced as much as possible, the environment of protection human survival.
The technical scheme in the invention for solving the technical problem is: a kind of vehicle exhaust low-temperature catalytic oxidation purifier, form by suction tude, steam outlet pipe, matrix, catalytic convention design, matrix is made up of inside and outside jacket casing together, one end of matrix connects suction tude, the other end connects steam outlet pipe, and catalytic convention design is fixed in the matrix by clamp device.
Around, stacking forming, the steel wire material is that diameter is the OCr18Ni19 steel wire of 0.1-2 millimeter to catalytic convention design in the utility model, scribbles platinum (Pt), rhodium (Rh), palladium oxidation catalysts such as (Pd) with plasma spray on it by the steel wire circle.
The invention has the beneficial effects as follows, simple in structure, catalysed oxidn produces at low temperatures, make the steel wire diameter of steel wire can be very little, the spraying of oxidation catalyst can be more even, and catalytic convention design can not be prematured by solids yet, particularly the harmful gas in the waste gas significantly reduces, according to detection, through after the purification of the present utility model, the purification ratio of the CO in the waste gas, HC, NOx, PT reaches 36.0%, 32.7%, 33.6%, 52.5% respectively.
Description of drawings
Fig. 1 is the utility model embodiment's a vertical section structure schematic representation.
Fig. 2 is the structural representation of catalytic convention design embodiment in the utility model.
Fig. 3 and Fig. 4 are respectively two embodiment's schematic representation of clamp device.
Among the figure, the 1st, suction tude, the 2nd, steam outlet pipe, the 3rd, matrix, the 4th, catalytic convention design, the 5th, clamp device, the 6th, urceolus, the 7th, inner core, the 8th, internal layer lid, the 9th, outer cover.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The catalytic convention design 4 of the cylindrical shape that the steel wire circle that is coated with oxidation catalyst equably matches around the internal diameter of, stacking one-tenth and inner core 7, fill in the centre of inner core 7, clamp device 5 is fixed, inner core 7 is fixing by internal layer lid 8 and suction tude 1, steam outlet pipe 2, and urceolus 6 is fixing by outer cover 9 and suction tude 1, steam outlet pipe 2.
In order to reduce in the purifier the area that stops to waste gas, and clamp device 5 is fixed catalytic reforming unit 4 reliably again, clamp device 5 can be lambdoid, also can be cross or other shape, fixing with inner core 7 welding to back, catalytic convention design 4 location.
Between inner core 7 and urceolus 6, sink can be set.
The utility model is installed in the appropriate location of Diesel Engine Exhaust Pipe, and waste gas enters matrix 3 by suction tude 1, and the temperature in the matrix 3 is lower usually, is generally below 800 degree, by after the catalytic convention design 4, is discharged by steam outlet pipe 5 at last.
Claims (3)
1. a low-temperature catalytic oxidation purifier is made up of suction tude (1), steam outlet pipe (2), matrix (3), catalytic convention design (4), and it is characterized in that: catalytic convention design (4) is fixed in the matrix (3) by clamp device (5).
2. a kind of low-temperature catalytic oxidation purifier according to claim 1, it is characterized in that: catalytic convention design (4) by the steel wire circle around, stacking forming, the steel wire material is that diameter is the OCr18Ni19 steel wire of 0.1-2 millimeter, scribbles platinum (Pt), rhodium (Rh), palladium oxidation catalysts such as (Pd) with plasma spray on it.
