Abstract
The utility model relates to a metal carrier of catalysts for purifying exhaust gas of motor vehicles. By using metal as a carrier of catalysts for purifying exhaust gas of motor vehicles, the carrier has the advantages that the carrier has high strength, the carrier is not easy to have poisoning, etc. However, the carrier has the problems that catalysts are easy to fall, and how to further reduce airflow resistance. Micropores with certain density and protruded spikes are arranged on a metal carrier sheet, which not only can increase the adhesive area and the adhesive force of the catalysts, but also can reduce airflow resistance.
Description
The utility model belongs to a kind of metallic carrier that is used for the motor vehicle vent gas purification catalysis agent, also is applicable to the metallic carrier of plant gas cleaning catalyst.
Common tail gas cleaner for motor-driven vehicle is to allow tail gas stream through having the purifier of catalyst, makes the CO in the tail gas, and pernicious gases such as HC burn under catalyst action and become CO
2And water, the carriers that adopt coccoid or cellular pottery to make catalyst in the prior art more, its low price, technology is simple, but gas-flow resistance is big, increased the engine power loss, and easy to wearly shaken brokenly, the life-span is short, the easy contaminated obstruction of its aperture, catalyst poisoning lost efficacy, so there is research to make catalyst carrier with metal in recent years, it is little that metallic carrier has gas-flow resistance, life-span is long, the intensity advantages of higher, but have the caducous deficiency of catalyst attached thereto, also there is the problem that how further to reduce gas-flow resistance simultaneously.
The utility model aims to provide a kind of metallic carrier that can increase catalyst adhesive force and bond area and can further reduce the motor vehicle vent gas purification catalysis agent of gas-flow resistance.
The technical scheme that realizes above-mentioned purpose is: the metallic carrier of attached catalyst is characterised in that: metallic carrier is a sheet, is provided with the micropore of the band projection burr with certain density on sheet metal.
The general available acupuncture method for processing of metallic carrier forms the micropore of band projection burr.
With sintering of catalyst on the sheet metal of this band projection burr micropore, not only can increase the bond area of catalyst, and can improve the adhesive force of catalyst and metallic carrier greatly, simultaneously this structure has increased by micropore to the passage that flows with the metal covering vertical direction air-flow, thereby can further reduce the resistance of air-flow.

Embodiment 1 (Fig. 2 to Fig. 4)
This example is the metallic carrier sheet with unidirectional projection burr micropore, adopts unidirectional needle-punching method to be processed into, and promptly the burr of projection is all on a face of sheet metal.
Sheet thicknesses 0.1mm, micro-pore diameter 0.15mm, density 100 holes/cm
2
From improving catalyst bond area and adhesive force, reduce vapour lock and reduce composite factors such as micropore obstruction and consider that common metal sheet thickness can be selected in the 0.06-0.15mm scope, micro-pore diameter can select the density can be at 80-100 hole/cm in the 0.1-0.2mm scope
2Select in the scope.
Embodiment 2 (Fig. 5 to Fig. 7)
This example is the metallic carrier sheet with two-way projection burr micropore, adopts two-way needle-punching method to be processed into, i.e. all bossed burr on two of sheet metal faces.
This example is processed into two-way needle-punching method, promptly prick out the micropore of some band projection burrs earlier at sheet metal from a direction with mould, prick out the hole of some band projection burrs more the other way around at the golden back side with mould, the metallic carrier sheet promptly is the double-sided belt burr like this.The adhesive force of catalyst on this metallic carrier can adapt to the different directions air-flow, has further improved the adhesive force of catalyst.
Embodiment 3 (Fig. 8)
This routine metallic carrier structure is: the planar metal sheet 5 by band projection burr micropore rolls into this two metal level bar shape alternately with corrugated sheet metal 4.
Ripple on this routine corrugated sheet metal can form the axial flow passage, and the micropore on its sheet metal is then for air-flow provides the radial passage, so can reduce gas-flow resistance greatly.
