Description
Technical field
The present invention relates to a kind of water separating membrane treatment facility, relate in particular to a kind of hollow fiber film assembly that is applied to water treatment, belong to water-treatment technology field.
Background technology
Owing to membrane science and the development of technology and the update of water technology, the product of membrane separation technique and employing membrane separation technique is applied to water treatment field more and more in recent years.Along with the continuous maturation of popularizing gradually of using of engineering and production technology, the price of film product descends to some extent.But in general, the one-time investment of embrane method water technology and operating cost are still apparently higher than other comparatively ripe conventional water technologies, especially the short partially replacement cycle that brings of film life of product is short, make actual embrane method engineering of water treatment bear higher depreciable cost, this has limited membrane technology to a great extent and has further enlarged range of application in water treatment field.
Scientific research personnel and film product development manufacturing enterprise think that the film life of product mainly comes from film than weak point and pollutes at present.Film pollutes materials such as being defined as particle, colloid, emulsion, suspension, big molecule and salt on the film surface or the reversible and irreversible deposition of fenestra inside, and this deposition comprises absorption, obstruction, precipitation, formation filter cake etc.The development that film pollutes makes the strainability of film descend gradually, and the water-yielding capacity of film is decay thereupon also, when serious even lose water-yielding capacity substantially, has greatly influenced the stable operation of water processing establishment.The phenomenon of film film pollution in use is inevitably, so the researcher pays close attention to inhibition and removing means that film pollutes more except the formation mechanism and influence factor of deeply investigating the film pollution.At present in the middle of actual engineering, when the film pollution develops into to a certain degree, will take the chemical agent of online or off-line to clean measure to it, though this can recover the strainability of film to a great extent, but clean used chemical agent and all membrane material is caused to a certain degree damage, Chemical cleaning has equally also shortened the actual life of film product continually.
In fact, in use the wasting phenomenon of membrane material also is the assignable cause that the film life of product is short, depreciable cost is high.In the middle of several membrane component forms such as flat sheet membrane, tubular membrane and hollow-fibre membrane, hollow-fibre membrane has obtained because loading density is big, cost is low using widely.The hollow fiber film assembly made from hollow fibre membrane component has curtain formula, bundle formula and three kinds of basic forms of pillar.Relevant doughnut curtain type film assembly can be referring to Chinese patent and patent application 00102210.5,01820629.8,03803307.0,200410098416.8,200420029295.7,200510013293.8,200510015570.9,200510116589.2,200520123501.5,200610104225.7.Relevant hollow fiber bundle formula membrane module can be referring to Chinese patent and patent application 02158708.6,02158711.6,03822704.5,200420029337.7,200420109650.1,200510049324.5,200580025651.5,200610065807.9,200620039621.1,200710056641.9.Relevant doughnut pillar membrane module can be referring to Chinese patent and patent application 99800749.8,01229169.2,01229790.9,03121949.7,200310100565.9,200420056864.7,200420056865.1,200480028264.2,200510015346.X and 200520027729.4,200610129352.2.Problem of the equal ubiquity of above-mentioned these hollow fiber film assemblies, the promptly undue loading density of pursuing, a large amount of hollow-fibre membrane silks, usually thousands of even up to ten thousand hollow-fibre membrane silk, by potting in a stiff end, this not only causes membrane module potting operation in process of production difficulty of processing big, the percent defective height, in case and part film silk fracture in the process of using, even if other most of film silks still structure are intact and have a good strainability, but because together with the film silk potting of having ruptured, film silk in can not carrying out is among a small circle changed, therefore whole intrafascicular hollow fiber film or whole membrane module just can't continue to use, and have caused unnecessary waste, have increased the depreciable cost of film product.
Summary of the invention
An object of the present invention is to provide a kind of hollow fiber film assembly, this membrane module can improve the utilization rate of hollow-fibre membrane silk and the service life of hollow fiber film assembly.
In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:
The invention provides a kind of hollow fiber film assembly, comprise the hollow fiber membrane bundle of forming by the hollow-fibre membrane silk, the termination and the water producing pipe of hollow fiber membrane bundle one or both ends, it is characterized in that: described hollow-fibre membrane silk number is less than or equal to 500, the cross-sectional area sum of described hollow-fibre membrane silk accounts on the termination casting end face has the percentage of the area in hollow-fibre membrane silk zone to be less than or equal to 40%, the termination of described hollow fiber membrane bundle one or both ends refers to, and an end of hollow fiber membrane bundle has termination or two ends that the termination is all arranged.
This paper hollow-fibre membrane silk is also referred to as the film silk, and hollow fiber membrane bundle is also referred to as the film bundle.
When described hollow-fibre membrane silk number during greater than 500, if the fracture of part hollow-fibre membrane silk is arranged, even if other most of film silks still structure are intact and have a good strainability, but because together with the film silk potting of having ruptured, film silk in can not carrying out is among a small circle changed, therefore whole hollow fiber film assembly just can't normally use, so the number of hollow-fibre membrane silk can not be too big, so just can reduce unnecessary waste.And the cross-sectional area sum of hollow-fibre membrane silk accounts for has the percentage of the area in hollow-fibre membrane silk zone can not be greater than 40% on the termination casting end face.
In the research and use of traditional hollow fiber film assembly, researcher and engineers and technicians pursue the hollow-fibre membrane silk that comprises as much as possible always in a hollow fiber film assembly, the number of the hollow-fibre membrane silk that a common assembly comprises is thousands of even up to ten thousand, Duo hollow-fibre membrane silk is in the process of boundling like this, and the percentage that the cross-sectional area sum of inevitable requirement hollow-fibre membrane silk accounts for this region area is also very big.The inventor is on the basis of a large amount of research and analysis, think that the hollow fiber film assembly that satisfies following condition can overcome above-mentioned technical problem, be that hollow-fibre membrane silk number is less than or equal to 500, the cross-sectional area sum of described hollow-fibre membrane silk accounts on the termination casting end face has the percentage of the area in hollow-fibre membrane silk zone to be less than or equal to 40%.
