Description
Technical field
This utility model is related to technical field of membrane separation, more particularly to a kind of flat board ceramic honey comb film.
Background technology
Membrane separation technique has been referred to as in the world one of new and high technology of 21st century most application prospect.Ceramic membrane is
Membrane separation technique of new generation, is with Al2O3、ZrO2、TiO2、SiO2, a series of tool that is made of special process of raw material Jing such as SiC
There is the separation material of loose structure.Ceramic membrane is divided into tubulose, multichannel and tabular according to shape.With traditional tubulose and Duo Tong
Road ceramic membrane is different, and ceramic membrane is filtered using external-compression type, and the outer surface of ceramic membrane is stratum disjunctum, and fenestra road is logical for penetrating fluid
Road.Due to eggshell effect, using this structure, for ultra-thin ceramic membrane, the wall thickness of its supporter can be as small as
1mm, the thickness of whole Flat Membrane in 3~5mm, so as to significantly reduce the osmotic resistance of ceramic membrane.But, this structure also must
So bring problems with：
(1) increased the requirement to forming technique.In particular by extrusion moulding, need to control pug property to avoid
Ceramic film support deforms.
(2) bulk strength of ceramic membrane is inadequate.Although the buckling strength of membrane material is not changed in, due to supporter
Thickness is less, and the pressure that ceramic membrane can bear is less, easily snaps off.
(3) membrane area of unit volume is less.Because the external surface area for adopting slab construction, ceramic membrane is film surface
Product, for component, the membrane area of the ceramic membrane that can be installed in unit volume is less than Multichannel ceramic membrane.
(4) the preparation difficulty of ceramic membrane separation layer increases.Because the thickness of supporter is reduced, it is difficult to using traditional cement-dipping method
Enough thicknesses of layers (10 μm of general ＜) are obtained, film defect is also easy to produce.
At present, prior art is for the preparation of tabular ceramic film support, also have using injection moulding, gel injection-moulding into
The methods such as type, but consider from the performance and preparation efficiency of ceramic film support, extrusion moulding still has obvious advantage.So
And, the method for prior art extrusion molding does not propose to be effectively improved to arrange for the technology of preparing of ultra-thin ceramic membrane
Apply.Additionally, further to improve unit volume membrane area, large-sized thin wall hollow flat ceramic has also been researched and developed at present
Film.But size is bigger, either deformation is still easily caused during later stage drying and calcination in molding, particularly can be increased
Plus there is the probability of film defect in ceramic membrane.And, as the change of size is big, it is existing that vibration easily occurs in membrane filtration processes in thin plate
As easily rupturing because of resonance.
In terms of preparative separation film layer, prior art generally uses cement-dipping method, in addition with being applied using vacuum impregnation
The method of film, but not special adaptations.For this purpose, also having researched and developed plasma spraying preparative separation film layer, but substantially increase
Ceramic membrane cost；And compressed air is adopted for source of the gas, and film layer is prepared by spraying, under the brushing of compressed air, film layer is held
Easily ftracture because of rapid draing.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of combined flat plate ceramic honey comb film,
With tabular ceramic honey comb lamina membranacea as unit, large scale, the combined flat plate of different shape structure are obtained by way of split
Ceramic honey comb film.
The purpose of this utility model is achieved by the following technical programs：
A kind of combined flat plate ceramic honey comb film that this utility model is provided, by tabular ceramic honey comb film unit split structure
Into；The tabular ceramic honey comb film unit is narrow boards shape, and the edge shape of its two avris is symmetrical in central rotation；The flat board
It is connected with avris in the width direction between shape ceramic honey comb film unit and is spliced.
The edge of this utility model tabular ceramic honey comb two avris of film unit is symmetrical in central rotation, therefore in width
Can be fitting to connection well between the ceramic membrane unit of direction.Further, tabular ceramic honey comb film described in the utility model
Width≤the 15cm of unit.
In such scheme, the avris of tabular ceramic honey comb film unit described in the utility model its edge cross-section is shaped as directly
One kind or its combination in line, camber line, curve, broken line.Tie in plane, knuckle between the tabular ceramic honey comb film unit
Structure or the split of W type corrugateds connect, it is hereby achieved that plane or the large scale flat board ceramic honey comb of bending structure combination
Film, and bending structure is conducive to structural stability of the raising flat board ceramic honey comb film in running.
In such scheme, thereon outer lower face surface is separation membrane layer to tabular ceramic honey comb film unit described in the utility model,
There is single or double penetrating fluid duct in it.The thickness of the separation membrane layer is 15~25 μm.
This utility model has the advantages that：
(1) this utility model is only with tabular ceramic honey comb film unit, by the split of multiple units, you can obtain big chi
The combined flat plate ceramic honey comb film of very little, different shape structure.Splice by 180 °, in the way of in planar structure, can obtain big
The unit volume membrane area of size flat-panel ceramic honey comb film；Bending structure, W type corrugateds that at other angles split is formed,
With gusseted effect, be conducive to structural stability when improving operation, for the flat board ceramic honey comb film (example of long length
Such as larger than 1m), feed liquid caused ceramic membrane resonance to washing away for supporter in membrane filtration processes can be effectively reduced, so as to effective
Reduce the probability of ceramic membrane fracture；And, the structure such as this bending, W type corrugateds, it helps improve the turbulent flow of feed liquid
Degree, reduces fouling membrane, improves permeability of the membrane energy.
(2) this utility model is by the way of splicing, and combination is flexible, changes convenient.Due to dividing for flat board ceramic honey comb film
From film layer ceramic membrane upper outer lower face surface, therefore each ceramic membrane unit split connection will not to membrane separating property produce shadow
Ring, can be with independent assortment.And, such as the separating property of single ceramic film unit declines, only by changing defective ceramic membrane
Unit, you can keep the performance of large scale flat board ceramic honey comb film.
