Abstract
The utility model discloses a woven reinforced hollow fiber membrane which comprises hollow fiber membrane yarns, wherein every three hollow fiber membrane yarns are integrated into a bundle, and a layer of net structure is woven on the external surface of each bundle of hollow fiber membrane yarns. External support fiber weaving is conducted on the membrane bundles integrated by the three hollow fiber membrane yarns, and the weaving is sparse; compared with that the external support weaving is conducted on the single hollow fiber membrane yarn, the weaving efficiency is improved greatly, woven fiber raw materials required for supporting are greatly decreased correspondingly, and the cost for producing the raw materials, production equipment cost and labor cost are further lowered.
Description
Technical field
The utility model relates to sewage treatment area, and specifically, the utility model relates to a kind of fibrage enhancement type hollow fiber film for membrane bioreactor.
Background technology
Polymer hollow tunica fibrosa advantage is that specific area is large, loading density is high, volume is little, treatment effeciency is high, production technology is simple, has been widely applied to the fields such as the processing of municipal wastewater, middle water reuse, medication chemistry now.Because the immanent structure of polymer hollow tunica fibrosa is loose structure, thereby its mechanical strength is not high, self-supporting hollow-fibre membrane tensile strength and bend resistance intensity are lower, its hot strength is generally in the 5MPa, when in the more serious separation of damage ratio and concentrated field, using, especially when using the air concussion cleaning method, the problems such as fracture of wire appear easily.
When doughnut film diameter was thinner, the anti-pull-off force of hollow-fibre membrane was little; When doughnut film filament diameter is thicker, because doughnut belongs to self-supporting, for keeping certain anti-flattening, must strengthen the wall thickness of hollow-fibre membrane, not only increased the production cost of hollow-fibre membrane, and the degree that the doughnut film-strength improves is limited, and more prior is that unit effective film area significantly reduces, and increases the engineering operation cost.
In order to expand the scope of application of hollow-fibre membrane in engineering of water treatment, improve the mechanical strength of polymer hollow tunica fibrosa, preparation can be used for the hollow fiber composite membrane of external pressure and inner pressed filtration simultaneously, the people such as Yoon have proposed macromolecular fibre and casting solution are carried out the compound method for preparing hollow fiber composite membrane in patent (WO03/097221), by the autonomous channel fiber and casting solution are incorporated into respectively the spinning head outlet, when contacting film forming with core liquid, casting solution carries out compound preparation hollow fiber composite membrane, but because contact and recombination time are short, Compound Degree is limited, only have the part fiber dispersion in casting solution and adhesive force very weak, cause fiber that the humidification of hollow-fibre membrane is weakened.
Xu again first-class people (application number 201110243287.7) by carrying out long fibre and casting solution compound in advance, and long fibre is positioned in the casting solution, and suitably increase long stapled tractive force and realize long fibre distributing with fully compound in order and in hollow-fibre membrane with stretching, thereby the hollow fiber composite membrane for preparing a kind of long fiber reinforcement, the mechanical strength of the hollow fiber composite membrane that makes with the method can improve 3-5 doubly.But the spinning head complex structure that the method is used, interface binding power control and technology controlling and process are difficult for realizing, the bending of long fibre in casting solution easily occur in preparation process, thereby weaken the intensity of hollow fiber composite membrane.
The people's such as Chen Yili outer support enhancement type hollow fiber film (application number 201220001563.9) is by improving the doughnut film strength at the high-intensity network structure of the outer continuous continual braiding of hollow-fibre membrane, compare with the method for in the spinning casting solution, adding fiber, easily make resulting doughnut film-strength much larger than in the spinning casting solution, adding the resulting doughnut film-strength of fiber, but production efficiency reduces, the cost of raw material increases, and causes the masking cost to increase considerably.
For the prior art above shortcomings, the utility model is proposed.
The utility model content
In view of problems of the prior art, the fibrage enhancement type hollow fiber film that the purpose of this utility model is to provide a kind of and is widely used, technique is simple, cost is low.
For realizing above-mentioned utility model purpose, the technical scheme that the utility model provides is: a kind of fibrage enhancement type hollow fiber film, comprise hollow fiber film thread, hollow fiber film thread per three integrated a branch of, the outer surface of every a branch of hollow fiber film thread is woven with one deck network structure.
Described network structure is to be formed by the high-speed knitter braiding by polyester filament, and the number of spindles of high-speed knitter is the 4-32 ingot, and bipatch is 5-50mm.
The external diameter of described hollow fiber film thread is 1mm-5mm, and the wall thickness of hollow fiber film thread is 0.1mm-1mm.
The other optimal technical scheme that the utility model provides is, described network structure is to be formed by the braiding of crochet hook machine by polyester filament, and cancellated knitting density is the 4-20 order, and the pin number of described crochet hook machine is the 3-12 pin.
The beneficial effects of the utility model are: greatly improved the doughnut film strength because the outer layer fiber braiding strengthens body, permeability and separation performance and the strength character of film body are separated, therefore, in film-forming process, reduced the content that is used for guaranteeing film silk mechanics material of main part, the masking cost is significantly reduced, and the masking composition and engineering is simplified more.
Guaranteeing to reach film silk working strength, when satisfying service requirement, production efficiency is greatly improved.The utility model is to 3 film Shu Jinhang outer support fibrages that hollow-fibre membrane is integrated, weave sparse, with respect to single hollow fiber film thread is woven outer support, braid efficiency greatly improves, required passive braided fiber raw material are reduced greatly, and raw materials for production, production equipment and cost of labor further reduce;
With respect to former hollow-fibre membrane, the method does not cause the change of hollow fiber membrane filter performance, its original loading density changes little, in the situation that guarantee its original hollow-fibre membrane serviceability, increasing in the production cost situation of seldom measuring, just can widen the use field of hollow-fibre membrane, prolong engineering service life, reduce operation, maintenance and replacement cost.
Outer weaving and raw material selection aspect select fiber softer, excellent elasticity to carry out sparse braiding, are conducive to improve hollow-fibre membrane and swing, and improve the effect of cleaning, thereby can reduce the gas consumption when cleaning, and reduce the engineering operation cost.
