According to the double-channel ceramic filtering membrane, the path of liquid reaching a penetrating side from a material inlet side in the main body of the membrane is shortened, one penetrating side is added for the inner-layer membrane hole which is adjacent to the drainage hole by the drainage hole, the filtration resistance is greatly lowered, and the filtration efficiency is enhanced.
Description
Technical field
The present invention relates to the water filtration technology field, particularly relate to a kind of binary channels ceramic filter membrane.
Background technology
Current; Drinking-water is healthy all greatly to be paid close attention in countries in the world, and for removing the harmful substance that exists in the water for example bacterium, microorganism and heavy metal, the whole mankind can the exploration way in institute extremely to the greatest extent; For example means such as high temperature, bleaching are used extensively, but can not thoroughly remove the impurity in the water; Take the filter effect of modes such as filter cotton, active carbon also very limited, can't bring into play filtration for impurity and heavy metal that molecular volume is less or thinner.For this reason; Prior art adopts membrane filtration technique effectively to address this problem; Owing to need applying huge pressure to liquid, membrane filtration reaches little molecule through film and the purpose that big molecule tunicle stops, the problem that film filter ubiquity permeability of the prior art is poor, filtration resistance is big, filter efficiency is low and energy consumption is high to form pressure differential.
Summary of the invention
To the problems referred to above, the present invention provides a kind of binary channels ceramic filter membrane, compares with organic film, and it is good that ceramic membrane has chemical stability, and mechanical strength is big, and anti-microbe ability is strong, and is high temperature resistant, and pore-size distribution is narrow, the separative efficiency advantages of higher.
Utilize the advantage of ceramic membrane, the present invention provides a kind of binary channels ceramic filter membrane, and the film main body is cylindric; The center of circle has a conduction hole; Radially around the conduction hole be provided with two-layer fenestra, film in the fenestra, conduction hole picks out water pipe; The external water inlet pipe of fenestra; Penetrating fluid after the internal layer fenestra filters gets into conduction hole and reclaims through outlet pipe under the effect of water inlet pipe pressure, the penetrating fluid after the outer fenestra filtration oozes out and reclaims through the outer wall of binary channels ceramic filter membrane main body under the effect of water inlet pipe pressure, thus the formation binary channels.
Binary channels ceramic filter membrane of the present invention also can be made as a plurality of conduction holes, and each conduction hole is the structure of some fenestra drainages around it, thereby forms more multichannel filter membrane, further improves filter efficiency.
For guaranteeing the pressure of liquid in fenestra, described water inlet pipe and fenestra seal, and the compactness extent of water inlet pipe is greater than the compactness extent of film in the fenestra.
For further improving filter efficiency, axial entire body has some grooves on the film main body excircle.
The groove that has on the said film main body excircle, the position is corresponding with outer fenestra, and width is greater than the diameter of fenestra.
Binary channels ceramic filter membrane of the present invention has shortened liquid arrives per-meate side from feed side in the film main body distance, conduction hole of the present invention made its internal layer adjacent fenestra many per-meate side; Make liquid in arriving the path of per-meate side, gone out the outer wall of film main body many again a selection; According to the minimum principle of energy, liquid always can select the shortest distance to arrive per-meate side, thereby has solved the problem of filter membrane permeability difference; Reduce filtration resistance significantly, improved filter efficiency.
Description of drawings
Fig. 1 is a binary channels ceramic filter membrane structural representation of the present invention.
Fig. 2 is the structural representation of external water inlet pipe of binary channels ceramic filter membrane of the present invention and outlet pipe.
Fig. 3 is the structural representation of binary channels ceramic filter membrane outer wall fluting of the present invention and external water inlet pipe and outlet pipe.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Like Fig. 1, shown in Figure 2, binary channels ceramic filter membrane of the present invention, film main body 1 is cylindric; The center of circle has a conduction hole 2, radial internal layer fenestra 3 and outer fenestra 4, the fenestra inner wall film-coating of being provided with around the conduction hole; Conduction hole and outlet pipe are tightly connected, and fenestra and water inlet pipe are tightly connected, and liquid gets into from an end of fenestra; Trapped fluid is discharged from its other end; Infiltrate into conduction hole 2 under the effect of the liquid fluid pressure water inlet pipe 31 in the internal layer fenestra 3 and be recovered, ooze out and be recovered through the outer wall of film main body 1 under the effect of the liquid fluid pressure in water inlet pipe 41 in the outer fenestra 4 through outlet pipe 21, thus the formation binary channels.
For guaranteeing the pressure of liquid in fenestra, described water inlet pipe and fenestra seal, and the compactness extent of water inlet pipe is greater than the compactness extent of the film that is coated with in the fenestra.The compactness extent of described film is looked filtration institute's desired impact and is decided.
As shown in Figure 3, for further improving filter efficiency, axial entire body has some grooves 11 on film main body 1 excircle; The position is corresponding with outer fenestra; And width makes the easier outer wall that oozes out film main body 1 of penetrating fluid of outer fenestra, thereby further improves filter efficiency greater than the diameter of fenestra.The effect of this groove also is to make things convenient for film main body fixing in confined space.
Binary channels ceramic filter membrane of the present invention also can be made a plurality of conduction holes, and each conduction hole is the structure of some fenestra drainages around it, thereby forms more multichannel filter membrane, further improves filter efficiency.Institute's filtered liquid also is not limited only to water, also can be various oil or the industrial liquids that need to filter screening.
