Background technology
Compare with other separating technology, it is a kind of simple relatively, low separating technology of power consumption that film separates, and can reclaim and utilize component in the mixture in principle, thereby be widely used in bioengineering, oil, chemical industry, metallurgy, medicine and other fields.Film separates realizes that by membrane module its core is a filter membrane.Compare with organic film, ceramic filter membrane has that chemical stability is good, mechanical strength is big, anti-microbe ability is strong, high temperature resistant, pore-size distribution is narrow, the separative efficiency advantages of higher.Because the rigidity of ceramic material is better, is subjected to preparation technology's restriction simultaneously, the prior art ceramic membrane is mainly based on tubular type and multichannel tubular type at present.Yet because its film density of ceramic membrane of single tube configuration (being the membrane area in the unit volume) is lower, therefore the ceramic membrane of commodity production at present improves film density by increasing duct number (as 7,19,37 passages) mostly.In addition, be further to increase membrane area, ceramic filter element has also adopted the ceramic honey comb structure at present, increases membrane area in the unit volume by the method that increases fenestra road number, reduces channel diameter.
Yet in prior art multichannel/ceramic honey comb pipe configuration, the formed penetrating fluid in duct that is in the center need be through outside the long distance ability discharger, and this has obviously increased the osmotic resistance of film, has reduced permeation flux; And the ceramic honeycomb filter membrane is along with channel diameter and ceramic membrane pore wall thickness reduces, and more the penetrating fluid in multimembrane duct can only infiltrate into outlet by the inner duct of ceramic honey comb supporter, and the transport resistance of penetrating fluid also obviously increases.Be head it off, for the ceramic honey comb film, prior art adopts the method that part fenestra road is transformed into permeate passageway usually, to reduce the path of infiltration water outlet; Perhaps, along cross-wise direction slotted in the part duct, reserve the part fluting, use the method for sintering that the port that penetrates aquaporin is carried out shutoff then as penetrating water out in the port; In addition, also have and central duct do not filmed and as the filtration and infiltration side, and adopt in central hole that a drainage tube is drawn penetrating fluid, method that epoxy sealing is adopted in the gap between centre bore and the drainage tube, to reduce osmotic resistance, improve permeation flux.But prior art ceramic honey comb pipe configuration still exists following technological deficiency:
(1) utilizes the part passage as permeate passageway, can reduce the path of infiltration water outlet, but also reduced the membrane area in the unit volume simultaneously, run counter to the design original intention that increases membrane area by honeycomb configuration.
(2) need carry out post-processed to ceramic membrane, the post-production difficulty is higher for ceramic membrane, has further increased preparation technology's complexity.
(3) for methods such as port fluting or increase drainage tubes, need port be sealed, sealing difficulty is bigger, causes penetrating fluid to mix with feed liquid easily.For example, the port of cross-notching carries out the method for shutoff owing to relate to drying and sintering process, and the difference between plugging material and the ceramic honey comb performance forms hole easily, thereby causes feed liquid pollution infiltration water outlet in filter process easily.
(4) more, the complex process of the preparation section of ceramic honey comb film, the possibility of introducing defective increases, make that the yield rate of zero defect ceramic honey comb film is lower, the ceramic honey comb film of larger volume particularly, increase along with the ceramic membrane sectional area, yield rate also can be lower, thereby further increased originally just than higher ceramic membrane cost.

It is the feed liquid passage that the utility model filters the duct, and each ceramic honey comb film monomer is tabular, makes ceramic membrane have short seepage distance.Gap between the ceramic honey comb film monomer is a permeate passageway, and the hole wall infiltration in duct after, thereby flow out, have higher permeation flux after filtration by the gap between ceramic honey comb film monomer for penetrating fluid.
The utility model also can be taked following further measure: detachable being arranged on of described supporting member filtered the port, duct.Like this, can adjust the width of permeate passageway by the thickness of regulating supporting member according to the size of infiltration capacity; In addition, it is seriously polluted or replace defective ceramic honey comb film monomer to be convenient to disassembly, cleaning.
For reducing the transport resistance of penetrating fluid, the filtration duct is directly adjacent with permeate passageway in the utility model ceramic honey comb film monomer, and single duct can be adopted in promptly described filtration duct; Also can adopt double duct and have higher unit volume membrane area.Further, filter wall thickness between duct and the ceramic honey comb supporter outer surface in the described ceramic honey comb film monomer less than other position wall thickness, thereby have shorter seepage distance, the while can be improved the intensity of ceramic honey comb supporter.
It is a rectangle perpendicular to the cross sectional shape that filters the duct axis for ceramic honey comb film monomer described in the utility model, and the ceramic honey comb film filtering element after the combination is cuboid.Perhaps, this cross sectional shape is trapezoidal for containing arc, and the ceramic honey comb film filtering element after the combination is cylinder.
