Abstract
A ceramic honeycomb-shaped filter consists of ceramic honeycomb-shaped structure of the porous bulkhead which is provided with a plurality of channels. The average diameter of the hole is 0.1-0.4mm and is rectangle. The ceramic honeycomb-shaped filter is a cylindrical body. The ceramic honeycomb channel can load the noble metal catalyst or three way catalyst, and also can bear the nanometer grain-shaped catalyst. The utility model has wide prospect in the high temperature filtration and the locomotive tail gas disposal.
Description
Technical field
The utility model relates to a kind of ceramic honeycomb filter, in particular for the ceramic honeycomb filter of carrier.
Background technique
Ceramic honeycomb filter has had product to occur, as 02154555.3 ceramic honeycomb filter, it is made of the ceramic honeycomb tectosome with porous matter next door of dividing many runners, utilize waste gas by the particulate in the described porous matter next door filtering waste gas, wherein, the end of sealing regulation runner, described porous matter next door has catalyzer, to under the situation of measuring described porous matter next door by mercury penetration method, the porosity is that 60-75% and average pore size are 15-25 μ m.
Yet it is wider to need applicable surface, needs more rational aperture shape structure, the better ceramic honeycomb filter of pore-size distribution.
Summary of the invention
The purpose of this utility model is: it is wider to propose a kind of applicable surface, especially proposes a kind of have more rational aperture shape structure, the better ceramic honeycomb filter of pore-size distribution (carrier).
Technical solution of the present utility model is: ceramic honeycomb filter, and there is the ceramic honeycomb tectosome in the porous matter next door of dividing many runners to constitute, the average pore size that it is characterized in that the hole is 0.1-0.4mm, and is rectangular opening.
The utility model especially will be made cylindric body.
Can load there be catalyzer (noble metal catalyst or nanocatalyst) in described porous matter next door, and by measuring (being pressed into the water logging bubble), the porosity is 55-70% (water absorption rate is 20～30%), the more uniform ceramic honeycomb filter of pore-size distribution.
Characteristics of the present utility model are: the average pore size in hole is 0.1-0.4mm, and is the ceramic honeycomb filter of rectangular opening, and the ceramic honeycomb duct can supported precious metal catalyst or three-way catalyst, also can the loaded with nano pellet type catalyst.Application in high temperature filtration and vehicle exhaust processing has prospect very much.

Cylindric shape 1, porous matter next door 2, honeycomb structure 3.
Embodiment
The utility model ceramic honeycomb columnar structure, preparation comprises white clay, talcum, aluminium oxide and other steinheilite or mullite, water forms the mixtures of material batch of material, in mould, push, the porous matter next doors 2 that extrusion modling and form honeycomb formed article, this honeycomb formed article have cylindric shape shell 1, become honeycomb structure 3 to arrange in the enclosure.Elder generation's dried heats and rotate evenly and heat.Green compact are dry and fire honeycomb structured body.Green compact are heated to are about 1250-1350 ℃ temperature.Get finished product after insulation a period of time.The present invention gets the ceramic honeycomb filter base by the mould extrusion modling, divides the porous matter next door of many runners, and the average pore size in hole is 0.1-0.4mm, and is rectangular opening.Determine by mould.Especially will make cylindric body.
Claims (2)
1, ceramic honeycomb filter, the ceramic honeycomb tectosome that is provided with the porous matter next door of dividing many runners constitutes, and the average pore size that it is characterized in that the hole is 0.1-0.4mm, and is rectangular opening.
2, ceramic honeycomb filter according to claim 1 is characterized in that ceramic honeycomb filter is cylindric body.
