Abstract
The utility model discloses a kind of and Oxidation assembly, comprise housing, be arranged on the suction tude at housing two ends and outlet pipe, the carrier be arranged in housing, be arranged on the outer field buffer layer of housing, in described suction tude and outlet pipe, be respectively arranged with spiral guide sheet.The setting of the utility model spiral guide sheet, can increase the torsion of outlet pipe, and waste gas is discharged fast, to reduce carbon distribution, and fast cooling, the usefulness of effective lifting vehicle toxic emission.
Description
Technical field
The present invention relates to automobile exhaust purification equipment technical field, particularly relate to the ternary catalyzing unit on a kind of automobile engine exhaust pipe road.
Background technique
Ternary catalyzing unit major function is discharged into air after the harmful gas of discharging after engine combustion is changed into innocuous gas, catalyzer in catalytic converter can promote the oxidation reaction of hydrocarbon and carbon monoxide, and it is changed into water vapour and carbon dioxide respectively; Reduction of nitrogen oxide is become nitrogen simultaneously.But, in engine low-speed running situation, if a small amount of waste gas is all discharged by vent systems, back pressure diminished strength makes engine torque not enough, if waste gas anelasticity in vent systems is too high, carbon deposition quantity will be caused too high and reduce running usefulness, generation large quantity of exhaust gas and temperature and engine runs up, effectively can not get rid of, will vehicle mechanizm be damaged.
Model utility content
For overcoming above-mentioned deficiency, the invention provides a kind of can the and Oxidation assembly of effective lifting vehicle toxic emission.
The technical solution adopted in the utility model is: a kind of and Oxidation assembly, comprise housing, be arranged on the suction tude at housing two ends and outlet pipe, the carrier be arranged in housing, be arranged on the outer field buffer layer of housing, in described suction tude and outlet pipe, be respectively arranged with spiral guide sheet.
As the further setting of such scheme, described spiral guide sheet is provided with several pores.
As the further setting of such scheme, the shape of described carrier is cellular, and the material of described carrier is pottery or stainless steel, and the cellular duct wall of described carrier scribbles catalyst coat.
As the further setting of such scheme, described suction tude is provided with exhaust gas temperature sensor in housing joint.
As the further setting of such scheme, described buffer layer is inflated insert or steel net pad.
As the further setting of such scheme, described housing is also provided with bed course between carrier, and described bed course is wire netting or ceramic substrate.
The setting of the utility model spiral guide sheet, can increase the torsion of outlet pipe, and waste gas is discharged fast, to reduce carbon distribution, and fast cooling, the usefulness of effective lifting vehicle toxic emission.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, housing; 2, suction tude; 3, outlet pipe; 4, spiral guide sheet; 5, carrier; 6, buffer layer; 7, exhaust gas temperature sensor; 8, bed course; 9, pore.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1, a kind of and Oxidation assembly, comprise housing 1, be arranged on suction tude 2 and the outlet pipe 3 at housing 1 two ends, be arranged on the carrier 5 in housing 1, be arranged on the outer field buffer layer 6 of housing 1, spiral guide sheet 4 is respectively arranged with in described suction tude 2 and outlet pipe 3, described spiral guide sheet 4 is provided with several pores 9, the shape of described carrier 5 is cellular, the material of described carrier 5 is pottery or stainless steel, the cellular duct wall of described carrier 5 scribbles catalyst coat, described suction tude 2 is provided with exhaust gas temperature sensor 7 in housing 1 joint, described buffer layer 6 is inflated insert or steel net pad, described housing 1 is also provided with bed course 8 between carrier 5, described bed course 8 is wire netting or ceramic substrate.
Working principle of the present utility model is as follows: in suction tude 2 and outlet pipe 3, be respectively arranged with spiral guide sheet 4, a kind of automobile that allows can be provided to have the large Ramp Rate of torsion in motion, the torsion of traveling or the acceleration of tail speed can be increased, spiral guide sheet 4 is provided with several pores 9, allow gas can the channelling via the design of pore 9, mixed flow, increase torsion, waste gas are discharged, fast to reduce carbon distribution; And Oxidation assembly is made up of housing 1, vibration damping layer 6, carrier 5 and catalyst coat 4 part.Catalyst converter housing 1 is made up of stainless steel material, causes carrier to block in case scale comes off.Vibration damping layer 6 generally adopts inflated insert or steel net pad, plays sealing, insulation and immobilization carrier.Catalyst converter carrier 5 generally adopts ceramic honeycomb material, also has minority to adopt metal (stainless steel) material.Carrier 5 duct wall scribbles the active layer that one deck loosens very much, i.e. catalyst coat, it is based on r-Al2O3, the precious metal as active material is studded with at coating surface, be generally platinum (Pt), rhodium (Rh) and palladium (Pd), the oxidation reaction of rhodium (Pt) major catalytic CO and HC, Rh is used for the reduction reaction of catalyzing N Ox.
