本発明は、流体混合物の成分を分離するのに用いられる
選択透過膜中空繊維膜（セルロースアセテート系中空繊
維膜を除く）からなる流体分離素子の装置方法に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus and method for a fluid separation element comprising a selectively permeable hollow fiber membrane (excluding cellulose acetate hollow fiber membranes) used to separate components of a fluid mixture.
一般に選択透過性膜を用いて流体混合物から各成分を分
離したり、濃縮したりするには、逆浸透、限外−過の原
理が応用される。この際の流体分離速度は膜面積に比例
するため、いかにして単位容積当たりの膜面積を大きく
するかが膜分離を行うに当たっての課題であり、その解
決手段として中空繊維膜からなる繊維束を組み込んだ流
体分離素子が開発された。In general, the principles of reverse osmosis and ultrafiltration are applied to separate and concentrate components from a fluid mixture using a permselective membrane. Since the fluid separation rate in this case is proportional to the membrane area, the problem in membrane separation is how to increase the membrane area per unit volume.The solution to this problem is to use fiber bundles made of hollow fiber membranes. An integrated fluid separation element has been developed.

、Ｕ字型に折返されて埋め込まれている。A fluid separation element using a hollow 1a fiber bundle accommodates the hollow fiber bundle in a case, adheres the ends of the fiber bundle with resin, closes the fiber gaps, fixes the hollow fiber bundle, and stores the hollow fiber bundle in the case. is separated into two compartments. To explain a partially cutaway front view of a drawing showing an example of a fluid separation element,
A permselective hollow fiber bundle 2 is housed in the case l. This hollow fiber bundle 2 is folded back into a U-shape, and both ends are bonded and fixed with resin layers 3 and 31, and the fiber gaps are closed. Therefore, inside the resin layer 3, the hollow fiber bundle 2 penetrates and opens to the opposite side, and inside the resin layer 3', it is folded back in a U-shape and embedded.

Furthermore, it is fixed to the case 1 via the resin M3Fi O-ring 6, and the inside of the case 1 is connected to the inner chamber 4.
It is divided and isolated into outer room 5.

排出される。In the fluid separation element described above, the fluid to be treated is in the perforated pipe 7
) into the inner chamber 4 of the case 1 through the hole 8,
It is discharged from the outflow pipe 9. During this time, some of the components in the fluid to be treated pass through the hollow fiber membrane and flow into the hollow fibers, are discharged into the outer chamber 5 through the hollow portions within the fibers, and are discharged from the outflow pipe 10.

には幾多の問題がある。すなわち、−樹脂ＰＪ３，３／
に使用する樹脂は、種類のいかんを問わず水が存在する

不良を起こす。ところが中空繊維は乾燥すると透過性が
低下し、流体分離素子の性能が低下する。従って中空繊
維の性能を低下させることすく、強固に接着することは
きわめて困難である。Although the fluid separation element has the above-described structure, there are many problems in the portion where the permselective hollow fiber bundle 2 passes through the resin layers 3, 3I. That is, -resin PJ3,3/
Regardless of the type of resin used, the presence of water will cause poor emulsification or hardening, as well as a decrease in mechanical strength and poor adhesion. However, when hollow fibers dry, their permeability decreases and the performance of the fluid separation element decreases. Therefore, it is extremely difficult to bond firmly without reducing the performance of the hollow fibers.
また、選択透過性中空繊維は薄い活性層とこの活性層を
支持するスポンジ層からなり、仁のスポンジ層は、湿潤
状態の程度により膨潤、収縮の差が大きいため、流体分
離素子を組み立てたのちも不安定で樹脂と中空繊維との
界面で剥離したり、樹脂層にひび割れが生じて流体分離
素子としての用をなさなくなることがしばしば起こる。In addition, permselective hollow fibers consist of a thin active layer and a sponge layer that supports this active layer, and since the sponge layer has a large difference in swelling and contraction depending on the degree of wetness, it is necessary to It is also unstable and often peels off at the interface between the resin and the hollow fibers, or cracks occur in the resin layer, rendering it useless as a fluid separation element.

であることが好ましい。W 9-D 9 Water content (2) = -x 100 Since the specific gravity of water is approximately 1, OD: From the outer diameter of the hollow fiber: The inner diameter of the hollow fiber! = Yarn length measured using a microscope Furthermore, the hollow fiber membrane of the present invention can be obtained by formula (1) as described above.
That is, this means that the porosity (HB) of the hollow fiber membrane in the bonded area is suitably smaller than the porosity (HB) of the hollow fiber membrane in the effective area, and is preferably smaller.

が起こって流体抵抗が増加する等の欠点がある。When HB/HA is greater than 0.9, the water in the hollow fibers at the bonding part may be discharged into the inner chamber when the operation is stopped, or the bond may deteriorate due to forward osmosis when processing high concentration water. When the water in the adhesive part is discharged into the inner chamber and the adhesive part dries, the hollow fibers shrink, causing peeling and cracking at the interface between the hollow fibers and the adhesive resin. There are drawbacks such as an increase in fluid resistance due to blockage caused by swelling of the hollow fibers during operation.

ことが好ましい。In addition, the hollow m-thin membrane can be expressed by formula (2), that is, (where, HA
: Porosity of the hollow fiber membrane in the effective part H : Porosity of the hollow fiber membrane in the adhesive part) It is necessary to satisfy the following: : Outer diameter of the hollow fiber membrane at the adhesive part). Furthermore, this hollow fiber is preferable.

れや剥離を起こす欠点がある。When the value of 0DB10DA is smaller than 0.7, the inner diameter of the hollow fiber becomes small, the pressure loss of permeated water becomes large, and the performance of the fluid separation element is significantly reduced. Also 0DB10D
If the value of A is larger than 0.95, the gap between the hollow fibers becomes small, making it difficult to impregnate the adhesive resin, causing liquid leakage, and poor adhesion at the adhesive interface, resulting in cracking or peeling during operation. It has the disadvantage of causing
上述のような条件を充たす中空繊維は、中空繊維の接着
部を大気中で風乾するか、熱風乾燥することによって得
られるが、その乾燥程度を充分に制御することが必要で
ある。Hollow fibers satisfying the above conditions can be obtained by air drying the bonded portion of the hollow fibers in the atmosphere or by hot air drying, but it is necessary to sufficiently control the degree of drying.
本発明に使用する接着剤樹脂は、通常エポキシ樹脂を使

もしかし、中空ｍ維の材質を考慮して、これと親和性の
ある樹脂を選択するのが好ましい。The adhesive resin used in the present invention is usually an epoxy resin, but other thermosetting resins or thermoplastic resins may also be used. Preferably, a resin is selected.

繊維が充分に固着され処理能力が大幅に上昇する利点が
ある。By using the hollow fiber membrane of the present invention, not only will the hollow fibers not peel off at the resin bonded part and the resin part will not crack, but the pressure loss of the fluid separation element will not increase, and the As the diameter decreases, the filling density of the hollow fibers in the resin part decreases, making it easier to impregnate the adhesive resin into the gaps between the hollow fiber bundles, improving adhesive strength, and ensuring that the hollow fibers are sufficiently fixed, significantly increasing processing capacity. There are advantages to doing so.
