Abstract
A novel catalytic converter for pollutants exhausted by a motor vehicle comprises an air inlet pipe (1), an enlarged cone body (2), a supporting frame (3), catalyst (4), a direct cylinder body (5), a contracting cone body (6), an air outlet pipe (7) and a cone-shaped guide valve (8). A honeycomb ceramic carrier or a metal carrier coated with the catalyst with active components is arranged in the direct cylinder body. The catalytic converter is characterized in that the cone-shaped guide valve (8) is positioned at the middle part in the cavity of the enlarged cone body (2), and is combined into a whole with the enlarged cone body (2) through the supporting frame (3). After the adoption of the novel catalytic converter, compared with the prior device, the conversion rate of pollutants like Co, HC and Ox exhausted by the motor vehicle can be improved by 5 to 10 percent.
Description
Technical field
The utility model belongs to the auto parts machinery technical field, relates in particular to a kind of treatment device of automobile exhausting pollutant catalytic purification.
Background technique
Along with the development of society, the quantity of China's Motor Vehicle is more and more huger, and the waste gas of its discharge is also serious day by day to the pollution of atmosphere.For this reason, country has put into effect a series of relevant laws and regulations in succession, and has worked out corresponding automobile exhausting pollutant emission standard.
At present, the method for using external purification on the basis of emission controls by improving combustion, is separately generally adopted in the improvement of automobile exhausting pollutant, and promptly harmful components such as waste gas CO, the HC that motor is discharged with catalytic converter, NOx are converted into harmless CO
2, H
2O, N
2, to reduce pollution to atmosphere.Catalytic converter generally is made up of suction tude, expansion cone, straight barrel, contraction cone and steam outlet pipe.It in the straight barrel catalyzer that on honeycomb ceramic carrier or metallic carrier, is coated with active component.Generally speaking, it is shorter to enlarge cone, and the air-flow diffusion is insufficient, and the air-flow of flowing through on the catalyzer cross section is inhomogeneous, and the flow of intermediate portion is greater than peripheral part, thereby the transformation efficiency of catalyzer is descended.
Summary of the invention
The purpose of this utility model provides a kind of improved automobile exhausting pollutant purification device, makes the air-flow in the catalyzer cross section of flowing through even, improves the transformation efficiency of catalyzer.
Concrete technological scheme of the present utility model is as follows:
A kind of novel automobile exhausting pollutant catalytic converter, suction tude 1, enlarge cone 2, supporting frame 3, catalyzer 4, straight barrel 5, shrinking cone 6, is the catalyzer that is coated with active component on honeycomb ceramic carrier or metallic carrier in the steam outlet pipe 7, described straight barrel, be characterized in: a taper pilot valve 8 that is positioned at the middle part is arranged in expansion cone 2 inner chambers that connect suction tude 1, and this taper pilot valve 8 is formed one by supporting frame 3 and expansion cone 2.
The high h of the vertex angle theta of above-mentioned taper pilot valve and taper pilot valve has determined the distribution of air-flow.When the pinnacle of taper pilot valve enlarging cone on the plane, the vertex angle theta of taper pilot valve is littler 10～15 ° than the cone angle that enlarges cone, and the height h of taper pilot valve when enlarging the 2/5-3/5 of vertebral height H, in the time of can making exhaust contaminant flow through the catalyzer cross section, has good distribution.
This device is applicable to existing all kinds of oil-fired vehicles.
Description of drawings
Fig. 1 is a catalytic converter structure schematic representation of the present utility model.
Among the figure: 1. suction tude 2. enlarges cone, 3. supporting frame, 4. catalyzer, 5. straight barrel 6. shrinks cone, 7. steam outlet pipe, 8. taper pilot valve, θ. the drift angle of taper pilot valve, α. enlarge the cone angle of cone, the height of h. taper pilot valve, H. enlarges the height of centrum.
Embodiment
As shown in Figure 1, a kind of novel automobile exhausting pollutant catalytic converter comprises: suction tude 1, enlarge cone 2, and supporting frame 3, catalyzer 4, straight barrel 5 shrinks cone 6, steam outlet pipe 7, taper pilot valve 8.It in the described straight barrel catalyzer that on honeycomb ceramic carrier or metallic carrier, is coated with active component.
Taper pilot valve 8 is positioned at the middle part that enlarges cone 2, and this taper pilot valve 8 fuses by 3 supporting frames 3 and expansion cone 2.
The pinnacle of taper pilot valve 8 is on plane on the expansion cone 2, and taper pilot valve vertex angle theta is designed to littler 10～15 ° than the cone angle that enlarges cone; The height h of taper pilot valve is designed to enlarge the 2/5-3/5 of vertebral height H.The taper pilot valve can be for solid, can also be for hollow.
Working principle: when the waste gas that motor car engine is discharged enters expansion cone 2 through suction tude 1, owing in enlarging cone 2, installed taper pilot valve 8 additional, air-flow is evenly distributed when making the automobile exhausting pollutant enter the catalyzer cross section, thereby has improved the transformation efficiency of purification plant.
I type test with GB 18352.3-2005 " light-duty vehicle pollutant emission limit and method of measurement (Chinese III, IV stage) " is an example, after adopting catalytic converter of the present utility model, compare with original device, the conversion ratio of automobile exhausting pollutant CO, HC, NOx can improve 5-10%.
