Abstract
The utility model discloses a ceramic membrane with a toothed channel. Longitudinal grooves are uniformly distributed on the inner wall of the channel, edges of the cross section of the channel are in toothed arrangement, so that the inner wall of the channel of the ceramic membrane rises and falls, the area of the inner wall is increased, furthermore, filtering efficiency of the membrane is improved advantageously, turbulent flow or burble of liquid during filtering is generated to form unstable flowing, pollutants deposited on the surface of the channel of the membrane are reduced, and penetrability of the membrane is enhanced.
Description
Technical field
The utility model relates to the membrane separation technique field, relates in particular to a kind of ceramic membrane.
Background technology
That ceramic membrane has is high temperature resistant, intensity is high, resistance to chemical attack, inanimate object degraded, pore-size distribution are controlled, be easy to advantage such as regeneration, long service life and receive extensive concern, in fields such as waste water and exhaust-gas treatments wide application prospect is arranged.The prior art ceramic membrane is generally circular multichannel ceramic membrane, and its unit volume film effective filtration area is little, and filter efficiency is low; And in the filter process, liquid is that the master forms steady flow with the laminar flow in the passage, and pollutant is prone at the membrane channels surface deposition; Having reduced permeability of the membrane can; Cause the membrane filtration separative efficiency low, thereby improved the application of membrane separation technology cost, be unfavorable for the Industry Promotion and the application of ceramic membrane.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; Provide a kind of channel cross-section to be the ceramic membrane of profile of tooth; So that when improving unit volume film effective filtration area; Make liquid in filter process, produce turbulent flow or flow-disturbing and form unstable flowing, thereby reduce the deposition of pollutant on the membrane channels surface, improve permeability of the membrane can and filter efficiency.
The purpose of the utility model is achieved through following technical scheme:
A kind of profile of tooth passage ceramic membrane that the utility model provides; The inner wall even distribution of its passage has and is groove longitudinally; Its edge of the cross section of said passage is profile of tooth and arranges; Make the inwall of ceramic membrane passage have the fluctuating shape, not only enlarged inner wall area, and can form unstable flow (turbulent flow or flow-disturbing).
Further, said each profile of tooth of the utility model interconnects, and also is that vias inner walls all is to be constituted and be continuous fluctuating by profile of tooth sideline (face of groove), thereby has further increased the unstability of turbulent flow or flow-disturbing.
In the such scheme, consider form turbulent flow to the influence and the effect of filtering and produce and implement and factors such as lumber recovery, the said profile of tooth of the utility model is horn shape, the cross section of said passage is star, is advisable with 4～8 angles.The star that preferably has 6 angles can be reduced ceramic body in moulding or the heat treatment process because the cracking phenomena that unbalanced stress causes.
In addition, arranging of each profile of tooth of said its cross section of passage of the utility model can be round and have circumscribed circle and inscribed circle, said circumscribed circle diameter: inscribed circle diameter=1.5～1.8.
The utlity model has following beneficial effect:
(1) compare with traditional circular channel, the utility model ceramic membrane passage is non-circular, and the cross section of passage is profile of tooth, and inwall is the fluctuating shape, has significantly increased unit volume film effective filtration area, thereby helps improving the filter efficiency of film.
(2) non-circular passage helps when isolated by filtration, making liquid to produce turbulent flow, has reduced the deposition of pollutant on the membrane channels surface, thereby has improved the permeability of the membrane ability.
Description of drawings
To combine embodiment and accompanying drawing that the utility model is done further to describe in detail below:
Fig. 1 is the structural representation of one of the utility model embodiment;
Fig. 2 is 7 passage ceramic membrane structure sketch mapes embodiment illustrated in fig. 1;
Fig. 3 is 19 passage ceramic membrane structure sketch mapes embodiment illustrated in fig. 1;
Fig. 4 is two the structural representation of the utility model embodiment.
Among the figure: groove 1, profile of tooth 2, circumscribed circle 3, inscribed circle 4
The specific embodiment
Embodiment one:
Fig. 1～shown in Figure 3 is one of embodiment of a kind of profile of tooth passage of the utility model ceramic membrane, and the inner wall even distribution of its passage of ceramic membrane has and is groove 1 longitudinally, and its edge of the cross section of passage is profile of tooth 2 arranges, and each profile of tooth 2 interconnects and arranges and is round.As shown in Figure 1, profile of tooth 2 is horn shape and is 6, makes the cross section of passage be hexagram.The ratio of its circumscribed circle 3 of hexagram and inscribed circle 4 diameters is: circumscribed circle 3 diameters: inscribed circle 4 diameters=1.75.
The quantity of present embodiment ceramic membrane passage can be 1,7 (see figure 2)s, 19 (see figure 3)s or more.
Embodiment two:
Shown in Figure 4 be a kind of profile of tooth passage of the utility model ceramic membrane embodiment two, be with embodiment one difference: the ratio of its circumscribed circle of hexagram 3 and inscribed circle 4 diameters is: circumscribed circle 3 diameters: inscribed circle 4 diameters=1.46.
