Abstract
The utility model relates to a novel carrier of catalyst of an automobile ternary purifier. A stainless steel fine metal mesh is used as a base core, and the surface of the base core is wrapped and sintered with a layer of ceramic material to form a mesh-shaped ceramic carrier. Catalyst is sintered on the surface of the ceramic. The stainless steel mesh can be prefabricated into various geometric shapes for forming mesh-shaped ceramic carriers of various shapes. The carrier has the advantages of a honeycomb ceramic carrier and a metal carrier, removes the defects thereof and has the advantages of simple manufacture, material saving, low cost, long service life, favorable ventilation, high mechanical strength, low light-off temperature, etc. The utility model is a novel carrier of catalyst of a purifier.
Description
The utility model is a kind of novel carriers of the outer ternary cleaner catalyst of vehicle exhaust machine, is used for solving raising ternary cleaner catalytic conversion problem.
Used carrier in the outer ternary cleaner of present automobile machine can be divided into honeycomb ceramic carrier and metallic carrier two big classes, and these two kinds of carriers all have pluses and minuses separately; After the honeycomb ceramic carrier sintered catalyst, the loss of catalyst difficult drop-off, but the complex manufacturing technology of carrier own, yield rate is low, and thermal shock resistance is poor, is easy to fragmentation.Metallic carrier mostly is stainless sheet steel or thick bar silk screen, the catalyst direct sintering is in the metal surface, metallic carrier mechanical strength height, the heat conduction is fast, and initiation temperature is low, but the metal surface is easy to oxidation, the catalyst inefficacy that is easy to come off, above-mentioned defective has directly influenced service life of clarifier, for solving the shortcoming separately of two kinds of carriers, relevant department is explored.
The purpose of this utility model provides a kind of honeycomb ceramic carrier and metallic carrier advantage of combining, and has abandoned their a kind of new-type composite catalyst carriers of shortcoming separately.
The purpose of this utility model is to realize like this, with the stainless steel fine metal mesh is basic core, superscribe one deck ceramic material at the fine wire net surface and carry out sintering, make fine wire net surface parcel one deck ceramic material form netted ceramic monolith, catalyst again sintering on netted ceramic monolith surface.For the ease of being installed in the clarifier and the air communication mistake, the stainless steel metal silk screen can be pressed into required geometry in advance, forms the netted ceramic monolith of required geometry.This is a kind of novel composite catalyst carrier.
Concrete structure of the present utility model is provided by following examples and accompanying drawing; Fig. 1 is a woven wire, and Fig. 2 is netted ceramic monolith floor map, and Fig. 3 is single netted ceramic monolith schematic diagram, and Fig. 4 is single netted ceramic monolith schematic cross-section, and Fig. 5 is two kinds of netted ceramic monolith side schematic views of bellows-shaped.
Below in conjunction with accompanying drawing, describe the CONSTRUCTED SPECIFICATION that the utility model proposes in detail;
Fig. 1～Fig. 5 is basic core with the stainless steel fine metal mesh, wraps up one deck ceramic material in its surface, carries out sintering, makes woven wire surface sintering parcel one deck ceramic material, makes netted ceramic monolith, catalyst again sintering on netted ceramic monolith surface.The stainless steel fine metal mesh is pressed into required geometry in advance, makes the netted ceramic monolith of required geometry.
The utility model combines the advantage of honeycomb ceramic carrier and metal carrier, has abandoned it Shortcoming, it is simply with low cost to have a making, be difficult for oxidation after the sintered catalyst and come off, Machinery intensity height, heat-resisting impact is good, and the life-span is long, good permeability, materials are economized, the ignition temperature Spend lowly, low-temperature catalyzed conversion rate advantages of higher is the outer ternary cleaner catalyst of automobile machine Novel carriers.
