Description
Technical field
The utility model relates to the hollow-fibre membrane field, and specifically, the utility model relates to a kind of composite enhanced hollow-fibre membrane for sewage disposal and regeneration.
Background technology
Hollow-fibre membrane is also referred to as self-supported membrane, in the process of using, owing to can repeatedly stand the shock vibration of great deal running water in High-Pressure Water and the cleaning process and air-flow, the phenomenon of fracture of wire very easily occurs, thereby reduce the effect of processing.Hollow-fibre membrane is a kind of important form membrane in the modern application of membrane, and it has the high characteristics of loading density, has been widely used at present the many-sides such as Industrial Wastewater Treatment, sewage reuse, desalinization preliminary treatment at home and abroad.Hollow-fibre membrane is also referred to as self-supported membrane, in the process of using, owing to can repeatedly stand the shock vibration of great deal running water in High-Pressure Water and the cleaning process and air-flow, the phenomenon of fracture of wire very easily occurs, thereby reduce the effect of processing.
In order to solve the low problem of self-supported membrane intensity, at present, many colleges and universities and science institutes are all in the research of carrying out the high-intensity hollow tunica fibrosa, when adopting the standby self-supported membrane of NIPS legal system, the method that can pass through to regulate membrane material and preparation technology or in preparation, add nano-oxide, improve to a certain extent the doughnut film strength, but the DeGrain that improves.When adopting the standby self-supported membrane of TIPS legal system, also can improve to a certain extent the self-supporting film strength, still, TIPS method cost is high, and power consumption is large, and the resistance tocrocking of the self-supported membrane of preparing is bad.
In order to improve the hot strength of hollow-fibre membrane, a kind of method is that polyster fibre is penetrated hole special on the spinning head (Chinese patent 200510013255.2), adopt the non-solvent phase separation method to prepare fiber reinforcement type polyvinylidene fluoride hollow fiber miillpore filter, this method has improved the intensity of Pvdf Microporous Hollow Fiber Membrane, but fiber can affect rete and divides phase behavior in the feed liquid, causes film silk separating property to be difficult to stablize.Second method is that the mode that adopt to apply is fixed on Flat Membrane surface (US Patent No. Patent No.5,472,607) with reinforcement material, makes enhancement mode compound slab film, but the coat film has a significant impact the water permeability of composite membrane.The third method is to have coated successively anti-corrosion layer and hydrophily anti-pollution layer (Chinese patent 200820108190.9) outside hollow braided rope, the preparation enhancement type hollow fiber compound film, the method has satisfied hydrophily and high-intensity requirement simultaneously, but doughnut rope braiding speed is slow, spinning equipment and complex process, and enhancement layer, anti-corrosion layer and hydrophilic layer material are different, compatibility is poor, and easily genetic horizon and interlayer comes off.The 4th kind of method is through compiling filament and twining filament as strengthening structure (Chinese patent 201080015946.5) with non-woven, the dipping spinning solution, make non-woven enhancing hollow-fibre membrane, although the enhancing structure preparation speed of this method is fast, still have the problem of spinning equipment complexity.
For the prior art above shortcomings, the utility model is proposed.
The utility model content
In view of problems of the prior art, the purpose of this utility model is to provide a kind of simple in structure, compound enhancing hollow-fibre membrane of being easy to make.
For realizing above-mentioned utility model purpose, the technical scheme that the utility model provides is: a kind of compound enhancing hollow-fibre membrane comprises hollow-fibre membrane, the gluing fiber filament that has of the outer surface of described hollow-fibre membrane.
Described fiber filament is evenly distributed on the outer surface of hollow-fibre membrane along the axial bonding of hollow-fibre membrane for the 1-10 root.
Described doughnut film outer surface also comprises the fiber filament that unidirectional left-handed or unidirectional dextrorotation is risen and bondd along doughnut outer surface spiral, and helical pitch is 2mm-20mm.
Described doughnut film outer surface also comprises the bidirectional crossed fiber filament that rises and bond along doughnut outer surface spiral of left-handed and dextrorotation, and helical pitch is 2mm-20mm.
Described fiber filament is by the terylene of 20D-1000D, polyamide fibre, polypropylene fibre, viscose rayon, glass fibre or aramid fiber.
The beneficial effects of the utility model are: compound enhancing hollow-fibre membrane of the present utility model, and simple in structure, be easy to make, the doughnut film strength improves obviously, and cost is low, power consumption is little, and the resistance tocrocking of finished product hollow-fibre membrane is better.
