Description
Technical field
This utility model relates to vehicular equipment field, a kind of automobile exhaust purifier.
Background technology
The exhaust gas component that automobile is discharged mainly has Hydrocarbon, oxynitride, carbon monoxide, granulated carbon etc..The harmful gass such as the carbon monoxide in vehicle exhaust, Hydrocarbon, oxynitride are mainly changed into harmless carbon dioxide, water and nitrogen by oxidation and reduction by three-element catalytic.But catalyst surface deposited particles carbon can make catalyst surface active reduce even to lose efficacy, and the most most of exhaust purifiers can add defecator before catalyst carrier.But on the existing defecator used, the effect of deposited particles carbon is not very good, easily blocks, it is therefore desirable to frequently change defecator, greatly reduces the service life of depurator.
Utility model content
The purpose of this utility model is the deficiency for solving above-mentioned technical problem, it is provided that a kind of good purification, the automobile exhaust purifier of length in service life.
By the above-mentioned technical problem of solution, this utility model be the technical scheme is that automobile exhaust purifier includes casing, casing one end is provided with gas inlet, the other end is provided with offgas outlet, in casing, the flow direction subsection setup successively along tail gas has through hole honeycomb aluminium lamination, catalyst support layer and three-way catalytic apparatus, the two ends of described through hole honeycomb aluminium lamination are evenly equipped with opening, and the opening at two ends is connected by the hole being interconnected inside through hole honeycomb aluminium lamination.
The left end of described through hole honeycomb aluminium lamination is additionally provided with the part flow arrangement of dispersion tail gas stream.
Described catalyst support layer is through hole honeycomb aluminium block, and two ends are connected by the hole being interconnected by inside, and inner void wall is coated with catalyst layer.
Described casing is provided with the convenient detaching structure disassembled by through hole honeycomb aluminium lamination in the position of through hole honeycomb aluminium lamination.
Described part flow arrangement is at least one piece of through hole honeycomb aluminum plate.
The beneficial effects of the utility model are: 1, this utility model uses through hole honeycomb aluminium lamination as defecator, increases the precipitation quantity of the particulate matters such as granulated carbon and is not easily blocked, and the granulated carbon of deposition can also recycle, and dismounting cleaning is the most convenient；2, this utility model is using through hole honeycomb aluminium block as catalyst carrier, solves ceramic monolith and holds susceptible to plugging shortcoming, simultaneously because the specific surface area of through hole honeycomb aluminium block makes greatly catalytic effect more abundant；3, this utility model arranges through hole honeycomb aluminum plate at gas inlet, makes the tail gas stream dispersion that automobile is discharged, uniformly across casing cross section, it is to avoid cause local ageing to damage through hole honeycomb aluminium lamination and catalyst support layer, extends the service life of depurator；4, structure of the present utility model makes the noise of exhaust purifier also can greatly reduce, and can reach preferable damping effect simultaneously, have good application prospect on automobile.

Detailed description of the invention
Automobile exhaust purifier, including casing 1, casing 1 one end is provided with gas inlet 101, the other end is provided with offgas outlet 102, in casing 1, the flow direction subsection setup successively along tail gas has the dispersion part flow arrangement 2 of tail gas stream, through hole honeycomb aluminium lamination 3, catalyst support layer 4 and three-way catalytic apparatus 5, the two ends of described through hole honeycomb aluminium lamination 3 are evenly equipped with opening, and the opening at two ends is connected by the internal hole being interconnected of through hole honeycomb aluminium lamination 3.Catalyst support layer 4 is through hole honeycomb aluminium block, and two ends are connected by the hole being interconnected by inside, and inner void wall is coated with catalyst layer.Casing 1 is provided with the convenient detaching structure disassembled by through hole honeycomb aluminium lamination 3 in the position of through hole honeycomb aluminium lamination 3.Part flow arrangement 2 is one piece of through hole honeycomb aluminum plate.
In use, the tail gas that automobile is discharged enters in casing 1 at gas inlet 101, by through hole honeycomb aluminum plate, tail gas stream is disperseed, uniform by through hole honeycomb aluminium lamination 3, by in the hole of internal for the particulate matter filter deposition in tail gas to through hole honeycomb aluminum connection, then tail gas is by being coated with the through hole honeycomb aluminium block of catalyst layer, owing to the specific surface area of through hole honeycomb aluminium block is big, tail gas and catalyst is enable to be fully contacted, excellent catalytic effect.Tail gas after filtering and being catalyzed passes through three-way catalytic apparatus by HC, NOx, CO, granulated carbon etc. be converted into CO2、H2O、N2It is drained in air.After a predetermined time, can be disassembled by the detaching structure on through hole honeycomb aluminium lamination 3 sidewall, the materials such as the granulated carbon by through hole honeycomb aluminium lamination 3 inside deposition clear recovery by concussion etc., and the granulated carbon of recovery may be used for manufacturing carbon goods, rubber etc..This utility model simple in construction, convenient disassembly, be not easily blocked, good purification, is also greatly improved service life.The structure using the present embodiment arranges and the noise of exhaust purifier also can greatly be reduced, and reaches preferable damping effect simultaneously, has good application prospect on automobile.
Further, in order to make tail gas stream disperse evenly, part flow arrangement 2 can use 2 pieces or 3 pieces of through hole honeycomb aluminum plates, extends the service life of depurator.
The above is only the preferred implementation of utility model, and for those skilled in the art, on the premise of without departing from utility model know-why, it is also possible to make some improvement and modification, these also should be regarded as protection domain of the present utility model.
