Abstract
A hexagonal ceramic carrier of catalysts includes a cylindrical body and a plurality of holes penetrating the body, a wall part is arranged between two adjacent holes, the cross section of each hole is hexagonal, therefore, each hole is provided with six wall parts. In comparison with the surface area of a normal square inner-bore carrier with the same volume as the hexagonal ceramic carrier, the surface area of the hexagonal ceramic carrier is 1.5 times larger, so that the catalytic effect of catalysts can be realized more effectively.
Description
Technical field
The utility model relates to a kind of ceramic catalyst carrier, in particular for the ceramic catalyst carrier on the automobile.
Background technology
The industrialized development of automobile industry, the tail gas pollution that brings are also serious day by day, and Europe comes into effect the control criterion of exhaust emissions already, and present exhaust emission standard is European IV discharge standard.China recent years has also begun to pay attention to the motor vehicle exhaust emission problem.Just coming into effect European III exhaust emission standard, just discharging standards III.
Ceramic catalyst carrier is the core component in the automobile exhaust gas purifying installation, in order to the absorption tail gas cleaning catalyst with purifying automobile tail gas.Catalyst carrier can make the cleaning catalyst of making have suitable shape, size and mechanical strength, to meet the operation requirement of industrial reactor; Ceramic catalyst carrier can make active component disperse in its surface, obtains higher specific surface area, improves the catalytic efficiency of unit mass active component.Modal so far is the carrier for ceramic honeycomb catalyst of 200 hole/inches square, 400 hole/inches square, but the China at present hole count that goes out of manufacturer production surpasses the carrier for ceramic honeycomb catalyst of 400 hole/inches square, wall thickness can not be lower than 1.7mm mostly, makes the catalytic effect of catalyst not good.
So, need a kind of new ceramic catalyst carrier to address the above problem.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of hexagonal ceramic catalyst carrier that improves the catalyst effect is provided.
For achieving the above object, the utility model hexagonal ceramic catalyst carrier can adopt following technical scheme:
A kind of hexagonal ceramic catalyst carrier includes columniform body and runs through some holes of this body, has wall portion between described two adjacent holes, and the cross section in described hole is a hexagon.
Compare with background technology, the utility model hexagonal ceramic catalyst carrier is a hexagon by the cross section in hole, make each hole have six wall portions, make the porosity of the utility model ceramic catalyst carrier on equal specific area greater than the poroid ceramic catalyst carrier of common square, thereby can more effectively bring into play the catalytic effect of catalyst.
Description of drawings
Accompanying drawing is the structural representation of the utility model hexagonal ceramic catalyst carrier.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
See also shown in the accompanying drawing, the utility model discloses a kind of hexagonal ceramic catalyst carrier 100 in order to purifying automobile tail gas.This hexagonal ceramic catalyst carrier 100 includes columniform body 20 and runs through some holes 30 of this body 20, has wall portion 31 between described two adjacent holes 30, the cross section in described hole 30 is hexagon (a preferred regular hexagon), make each hex hole 30 all have six wall portions 31, and this hole 30 distributed number on body 20 is 600/square inch, and the wall thickness of the wall portion 31 between described two adjacent holes 30 is 0.2 millimeter.
Existing result of study shows that ceramic catalyst carrier specific area (specific area is meant the gross area that the unit mass material is had) size, the size of porosity, the shape in hole all can have influence on the catalytic effect of catalyst to vehicle exhaust.Porosity is big more, and specific area is big more, and then gas-flow resistance is more little, and the result of use for catalyst of ceramic catalyst carrier is good more.Comparatively speaking, hex hole 30 the porosity on the equal specific area greater than the existing market on the common poroid ceramic honey comb (specific area is about 1.5 times of common square endoporus ceramic catalyst carrier) of square, make the utility model hexagonal ceramic catalyst carrier 100 can more effectively bring into play the catalytic effect of catalyst.
The utility model hexagonal ceramic catalyst carrier 100 selects for use cordierite as raw material, and the raw material that mix other ceramic honey combs are fired and formed.Because the distributed number of hole 30 on body 20 is 600/square inch, with respect to prior art, hole 30 density increase, can make catalyst obtain catalytic effect greatly, wall thickness between the hole 30 is 0.2 millimeter in addition, the prior art of comparing is thinner, can more effectively bring into play the catalytic effect of catalyst.After testing, these the utility model hexagonal ceramic catalyst carrier 100 thermal coefficient of expansions are for being 0.9 * 10
-6/ ℃, being parallel to axial strength is 23.5Mpa, 650 ℃ of air coolings of thermal shock resistance do not ftracture for three times.Reach European IV discharge standard through entrucking examination inspection.
