2About.For a membrane area is 16m
2Component devices, then need 7 assemblies to be together in parallel and to be competent at, and these 7 required parts of assembly are a lot, comprise assembly joint, admitting pipe joint, pipeline, valve etc., and floor space are also bigger, cost is also higher, this just is unfavorable for the miniaturization, high-effect of equipment, and simultaneously because cost, the price of film device also is higher, this has just weakened its power of striving unexpectedly on market, has limited its extensive use.In addition, the standard device of original 7 assemblies, because main line has certain length, in reality was implemented, 7 assembly flow regimes were not quite similar, and make also be not quite similar the service life of every assembly.Relevant patent has J62247296, CN1037180A, 85103278,86103358
The purpose of the utility model patent is to provide a kind of large-scale polysulfone hollow fiber ultrafiltration membrane system, start with from reducing membrane module material requested and volume, and then dwindle the external form volume of film device, reach the miniaturization, high-effect of equipment, reduce simultaneously cost of manufacture significantly, strengthen film device competitiveness in market mechanism.
For the film device of a typing, the size of kinetic pump and connecting line, valve is certain, can not change.If want volume miniaturization and reducing cost as much as possible, then can only under the prerequisite that does not reduce membrane area, reduce the membrane module number as much as possible, thereby reduce each accessory of connecting line, reduce the length of pipeline, the film device overall volume is dwindled and cost reduces thereby reach.
The utility model designs based on above-mentioned conception, the hollow fiber bundle of 7 independent Φ 75mm is installed in simultaneously in the thick shell of a Φ 200mm, and length is constant, still is 1m.The pipeline that has reduced original a whole set of assembly like this connects, be arranged in a row 7 independently assembly shortened one into and had only the thick big assembly of Φ 200mm, overall volume greatly reduces.Each the assembly joint, securing member, the seal that originally connect 7 assemblies have all saved, thereby have realized that equipment volume is as much as possible little and conception that membrane area is big as far as possible, and manufacturing cost also greatly reduces.In addition, the utility model is not owing to exist trunk line, and the import and export of 7 assemblies are are directly imported and exported with pump and linked to each other, and the flow regime of 7 assemblies is identical, thereby makes the life-span of assembly same, and filter efficiency is even.If which assembly goes wrong,, all stop up this assembly until doughnut and just really scrap through still using again after the leak detection repairing.Have, assembly of the present utility model two ends are provided with the floral disc that is used for the support hollow fibre bundle again, and this floral disc is to make with the ABS engineering plastics, establishes a plurality of circular holes on the dish, these circular holes with this floral disc center of circle be the axle center to around symmetric arrays.Two floral discs bond together with the shell inner rim respectively up and down.Because the existence of floral disc, make that the sealing of assembly termination is very firm tight, general assembly termination sealing resin and shell can not occur and break away from situation that the assembly termination has very high intensity, can bear very high pressure, this just lays the first stone for improving the assembly operating pressure.Each is connected assembly two ends of the present utility model with end socket with 8 bolts, repairing, easy removal.
The utility model is not limited to by 7 assemblies and shortens a big assembly into, also can be as the case may be or the membrane area of actual needs, handle component is made thicker big assembly, can be more diameter that the hollow fiber bundle of Φ 75mm is dressed up a big assembly in the thick shell.Certainly, the diameter of hollow fiber bundle is not limited to Φ 75mm, also can hollow fiber bundle become thick a bit or more carefully.But hollow fiber bundle is thick excessively, and then prepackage is made into difficulty of form shown in Figure 3, and the hollow fiber bundle termination is difficult for solid envelope, and the doughnut number that contains in the assembly is few, and promptly loading density is low; Hollow fiber bundle is meticulous, though the loading density height, the hollow fiber bundle bulk strength is little, flexible fractureing.Facts have proved that the diameter of hollow fiber bundle is advisable with Φ 40mm-Φ 100mm.In addition, the length of the hollow fiber bundle that is contained in the thick shell also is not limited to 1m, also can extend or shorten, but this is limited.Hollow fiber bundle is too short, though the flow regime of feed liquid in doughnut is good, the membrane area of assembly is little, and loading density is low; Hollow fiber bundle is long, though the membrane area of assembly increases, the doughnut beam intensity reduces, and the flow regime variation of feed liquid in doughnut, and flow resistance increases, and film easily pollutes and causes filtering rate to reduce.Facts have proved that hollow fiber bundle length is advisable with 500mm-1500mm.Have, the doughnut beam diameter that the utility model also is not limited in the assembly and is contained all is the same thicknesses, also can thickness load in mixture again.By geometrical principle as can be known, the doughnut beam diameter is more little, and the doughnut number that contains in the assembly is many more, and the membrane area of assembly is big more, and loading density is high more, but complex process, manufacture difficulty strengthens.Facts have proved that thickness loads in mixture, can be so that the membrane area of assembly strengthen, loading density improves, and can make manufacture craft simple again, reduces difficulty of processing.
The utility model provides 3 accompanying drawings, and Fig. 1 is an integral installation figure of the present utility model, and Fig. 2 is the profile of termination, and Fig. 3 is the prepackage figure of hollow fiber bundle.
The utility model is achieved in that package shell is cylinder, as shown in Figure 1. Cylinder Two ends respectively are provided with the end cap flange 1 of liquor inlet and outlet about the shell, and fastening bolt nut 2 is close Packing 3, big assembly flange 4, assembly sees through liquid outlet 5, cylinder 6, hollow fiber bundle end 7, big assembly floral disc 8, hollow fiber bundle 9, sealing resin 10, doughnut pipe joint 11.
7 intrafascicular hollow fiber bundles take the assembly center of circle as the axle center to around the symmetry axis symmetric arrays, such as Fig. 2 institute Show.
During the utility model work, the feed liquid that is provided by pump discharge enters big assembly through the assembly entrance In, the 7 intrafascicular hollow fiber bundles that contain in the big assembly since be take the center of circle of assembly as the axle center to around Symmetric arrays, thus feed liquid cross in each intrafascicular hollow fiber tube bank with identical flow velocity, traffic flow, Flow out from the end opening of the lower end doughnut of big assembly. In this flow process, compare hollow in the feed liquid The material permeance hollow fiber walls that the fiber aperture is little and come together in big package shell and doughnut encloses In the space, flow out from seeing through liquid outlet 6, material bigger than doughnut aperture in the feed liquid is thoroughly only fine Dimension film and flow out from the hollow fibre filament other end comes together in space that lower flange 4 encloses from lower end outlet stream Go out.
For making feed liquid flow point cloth more even, import and export and all adopt conical arc transition, such as Fig. 1 institute Show. Whole assembly is still vertically placed, like this to flow through the feed liquid of doughnut mobile very equal Even, also be identical thereby make the intrafascicular feed liquid that flows through of every intrafascicular hollow fiber, every intrafascicular hollow fiber bundle Transmission rates, efficient even, the life-span is same. If there is a hollow fiber bundle to go wrong, process Still can continue after leak detection is repaired to use, until doughnut all stops up, this assembly is then really scrapped.
