Abstract
A honeycomb ceramic catalyst carrier comprises a cylindrical body and a plurality of holes which penetrate through the body. A wall part is provided between two adjacent holes. The cross section of each hole is square. Furthermore the holes are distributed on the body with a number of 600 per square inch. Compared with the prior art, the number of the holes are increased thereby obtaining a better catalytic effect of the catalyst. The thickness of the wall between two adjacent holes is 0.14 millimeter. The catalytic effect of the catalyst can be exerted more effectively.
Description
Technical field
The utility model relates to a kind of carrier for ceramic honeycomb catalyst, in particular for the carrier for ceramic honeycomb catalyst 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.
Carrier for ceramic honeycomb catalyst 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; Carrier for ceramic honeycomb catalyst 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/square inches, 400 hole/square inches, but the hole count that the present manufacturer production of China goes out surpasses the carrier for ceramic honeycomb catalyst of 400 hole/square inches, wall thickness can not be lower than 1.7mm mostly, makes the catalytic effect of catalyst not good.
So, need a kind of new carrier for ceramic honeycomb catalyst 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 carrier for ceramic honeycomb catalyst that improves the catalyst effect is provided.
For achieving the above object, the utility model carrier for ceramic honeycomb catalyst can adopt following technical scheme:
A kind of carrier for ceramic honeycomb catalyst, include columniform body and run through some holes of this body, has wall portion between described two adjacent holes, the cross section in described hole is square, and the distributed number of this hole on body is 600/square inch, and the wall thickness of the wall portion between described two adjacent holes is 0.14 millimeter.
Compare with background technology, the utility model carrier for ceramic honeycomb catalyst is square by the cross section in hole, and the distributed number of this hole on body is 600/square inch, hole density increases compared to existing technology, make catalyst obtain catalytic effect greatly, the wall thickness of the wall portion between described two adjacent holes is 0.14 millimeter, and the prior art of comparing is thinner, can more effectively bring into play the catalytic effect of catalyst.
Description of drawings
Accompanying drawing is the structural representation of the utility model carrier for ceramic honeycomb catalyst.
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 carrier for ceramic honeycomb catalyst 100 in order to purifying automobile tail gas.This carrier for ceramic honeycomb catalyst 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 square, 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 0.14 millimeter.
The utility model carrier for ceramic honeycomb catalyst 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, density with respect to prior art hole 30 increases, can make catalyst obtain catalytic effect greatly, wall thickness between the hole 30 is 0.14 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 carrier for ceramic honeycomb catalyst 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.
