ＩＣやＬＳＩ等の半導体素子の製造には各種の薬液やガス体または超純水が用 いられ、混入物をきらい、より純度の高いものが要求されており、このような事 情は医薬品，遺伝子工学あるいは飲食品の分野においても同様で、ミクロンオー ダ以下の微粒子や細菌でも確実に捕捉できる高精度の分離部材が望まれている。 Various chemical solutions, gases, and ultrapure water are used in the manufacture of semiconductor devices such as ICs and LSIs. In order to avoid contaminants, there is a demand for products with higher purity. The situation is similar in the fields of pharmaceuticals, genetic engineering, and food and beverages. There is a need for a high-precision separation member that can reliably capture even microscopic particles and bacteria of less than 100 ml.
【０００３】 これに応える分離部材としては、例えばポリプロピレン等の合成樹脂素材から なり、外径が１０ミクロンないし１０００ミクロンで内径が２０ミクロン程度で 選択透過性の中空糸膜が好ましいとされ、一般には図７のように一定長さの上記 中空糸膜１を数千本ないし数万本集束し、その両端部をエポキシ系やウレタン系 等の合成樹脂で密閉状態に固定し、その固定部２を刃物で切断し、各中空糸膜１ を切口端面に開口させて両端開口式の中空糸膜モジュールＭ1 としたもの、又は 図８のように所要長さの上記中空糸膜１折り曲げて多数集束し、その端縁の会せ 部を上記のものと同様の合成樹脂で密閉状態に固定し、その固定部２を切断して 各中空糸膜１を切口端面に開口させ、一端開口式の中空糸膜モジュールＭ2 とし たもの等が知られている。[0003] As a separation member that meets this requirement, a permselective hollow fiber membrane is preferably made of a synthetic resin material such as polypropylene, has an outer diameter of 10 to 1000 microns, an inner diameter of about 20 microns, and is generally used. As shown in FIG. 7, several thousand to tens of thousands of hollow fiber membranes 1 of a certain length are bundled together, both ends of which are fixed in a sealed state with synthetic resin such as epoxy or urethane, and the fixed part 2 is The hollow fiber membranes 1 are cut with a knife and each hollow fiber membrane 1 is opened at the cut end face to form a hollow fiber membrane module M 1 with both ends open, or the hollow fiber membranes 1 are bent to a required length and bundled in large numbers as shown in FIG. Then, the meeting parts of the edges are fixed in a sealed state with a synthetic resin similar to that mentioned above, and the fixed part 2 is cut to open each hollow fiber membrane 1 at the cut end surface to form a hollow fiber membrane with one end open. A thread membrane module M2 is known.
【０００４】 そして、前者のモジュールＭ1 は底部に被処理流体（濃縮流体）の出口６，側 部にろ過流体取出口７を備えた筒状容器３内に収容し、一端の固定部２を容器３ の底部に密封支持すると共に他端の固定部２は被処理流体の入口５を備えた蓋体 ４で密封支持し、被処理流体を所要圧力のもとに入口５から出口６に向かって流 通させ、その間に各中空糸膜１を透過した処理ずみ流体を取出口７から取出すよ うにして用いられ、また後者のモジュールＭ2 は一端の固定部２をろ過流体取出 口７を有する蓋体４に密封支持させて、底部に被処理流体の入口５を設けたコッ プ状の容器３に収容し、入口５から取入れた被処理流体を各中空糸膜１を透過さ せて、流体中の混入微粒子を糸膜で捕捉しつつ処理ずみのろ過流体を糸膜内を通 じて取出口７から流出させるようにして使用されている。The former module M 1 is housed in a cylindrical container 3 equipped with an outlet 6 for the fluid to be treated (concentrated fluid) at the bottom and a filtrate outlet 7 at the side, and the fixing part 2 at one end is The fixing part 2 at the other end is hermetically supported by a lid body 4 having an inlet 5 for the fluid to be treated, and the fluid to be treated is directed from the inlet 5 to the outlet 6 under the required pressure. The module M2 is used in such a way that the treated fluid that has permeated through each hollow fiber membrane 1 is taken out from the outlet 7, and the latter module M2 has a fixed part 2 at one end connected to a lid having a filtrate fluid outlet 7. The container 3 is sealed and supported by a body 4 and is housed in a cup-shaped container 3 having an inlet 5 for the fluid to be treated at the bottom. It is used in such a way that mixed fine particles are captured by the thread membrane, and the treated filtrate fluid is allowed to flow out from the outlet 7 through the thread membrane.

ところで、上記従来のモジュールはいずれにしても、中空糸膜をランダムに束 ねただけのものであるため、各糸膜同士のすき間は不均一になり易く、使用時に 被処理流体を流通させた際、流路抵抗の小さい部分に集中して流れるようになり 、いわゆるチャンネル現象が生じてしまい、このチャンネル現象により分離機能 を果たさないデッドスペースが存在することになり、中空糸膜モジュールとして の分離効率を低下させてしまう。 そこで、この考案は中空糸膜モジュールとして、中空糸膜同士のすき間が不均 一にならず、使用時にチャンネル現象を起こさず、分離機能を低下させないよう にすることを目的とする。 By the way, in any case, the above conventional module bundles hollow fiber membranes randomly. Since it is only a sticky material, the gaps between each thread membrane tend to be uneven, and when used, When the fluid to be treated flows, the flow will be concentrated in areas with low flow path resistance. , a so-called channel phenomenon occurs, and this channel phenomenon causes the separation function to fail. As a hollow fiber membrane module, there will be dead space that does not fulfill the purpose. This will reduce the separation efficiency. Therefore, this idea was developed as a hollow fiber membrane module with uneven gaps between hollow fiber membranes. so as not to cause channel phenomenon during use and to prevent deterioration of separation function. The purpose is to
【０００６】 上記目的のもとにこの考案は、帯状の通気性シート状物の上に多数の一体長さ の中空糸膜を幅方向に並列させて配設し、その上に同じ通気性シート状物を重ね 合わせてサンドイッチシートとなし、その一端縁を熱融着して中空糸膜の密封部 を形成し、このサンドイッチシートをスパイラルに巻き込み、巻き込みロール体 の上記密封部とは反対側の端部を合成樹脂により固定し、該固定部を切断してそ の切口端面に各中空糸膜を開口させたことを特徴とするものである。[0006] Based on the above purpose, this invention consists of a number of integral lengths on a belt-like breathable sheet-like material. Hollow fiber membranes are arranged in parallel in the width direction, and the same breathable sheet material is layered on top of them. Combine them to form a sandwich sheet, and heat seal one edge of the sheet to seal the hollow fiber membrane. This sandwich sheet is rolled up into a spiral to form a roll body. The end opposite to the above-mentioned sealed part is fixed with synthetic resin, and the fixed part is cut off. The hollow fiber membrane is characterized in that each hollow fiber membrane is opened at the cut end surface of the hollow fiber membrane.
【０００７】[0007]
以下図１ないし図６を参照してこの考案の実施例について説明する。 図１において１１は一定長さの中空糸膜で、合成樹脂素材例えばポリプロピレ ンの半透膜により前記のような太さの中空糸状に形成されており、この中空糸膜 １１の多数のものを、これと同種の合成樹脂材で所要の厚さと幅（例えば、厚さ ０．１mmないし０．５mm，幅３０cmないし６０cm）の網体，織布，不織布などに 形成された帯状の通気性シート状物１３の上にその幅方向に並列させて一層又は 多層に配設し、更にその上に同じ帯状の通気性シート状物１４を重ね合せて中空 糸膜１１を挟み込みサンドイッチシートを形成する。 An embodiment of this invention will be described below with reference to FIGS. 1 to 6. In Fig. 1, 11 is a hollow fiber membrane of a certain length, which is made of a synthetic resin material such as polypropylene. The hollow fiber membrane is formed into a hollow fiber shape with the thickness described above using a semipermeable membrane. 11 of the same type of synthetic resin material with the required thickness and width (e.g. 0.1 mm to 0.5 mm, width 30 cm to 60 cm), woven fabric, non-woven fabric, etc. On the formed band-shaped breathable sheet material 13, one layer or It is arranged in multiple layers, and then the same band-shaped breathable sheet material 14 is superimposed on it to form a hollow A sandwich sheet is formed by sandwiching the thread membrane 11.
【０００８】 そのサンドイッチシートの一端縁をホットプレスにより熱融着して、図２のよ うに中空糸膜１１の密封部１５を形成し、この一端密封のサンドイッチシートを 合成樹脂製の芯棒１６上にスパイラルに巻き付けて所要直径のロール体となし、 これを一旦紐等でくくり、密封部１５と反対側の端部を図３のようにポリプロピ レンより融点の低いポリエチレン樹脂で密閉状態に固定し、その固定部１２を刃 物工具で鎖線に沿って切断し、多数の中空糸膜１１を切口端面に開口させ、図４ のような一端開口式の中空糸膜モジュールＭを形成する。[0008] One edge of the sandwich sheet is heat-sealed using a hot press, as shown in Figure 2. A sealed portion 15 of the hollow fiber membrane 11 is formed in the sea urchin, and this sandwich sheet with one end sealed is Wrap it spirally around a core rod 16 made of synthetic resin to form a roll body of the required diameter, Tie this with string, etc., and tie the end opposite to the sealing part 15 with polypropylene as shown in Figure 3. It is fixed in a sealed state with polyethylene resin whose melting point is lower than that of resin, and the fixed part 12 is attached to the blade. Cut along the chain line with a tool to open a large number of hollow fiber membranes 11 on the cut end surface, as shown in FIG. A hollow fiber membrane module M with one end open is formed.
【０００９】 その使用時には、図５のように上記中空糸膜モジュールＭの固定部１２の部分 をろ過流体の出口２３を有する蓋体２１に気密に取付けて、糸膜モジュールＭを 被処理流体の入口２２を備えたコップ状の容器２０内に収容し、容器２０と蓋体 ２１との突き合せフランジ部を緊締バンド２４により気密にかつ着脱可能に結合 する。[0009] When using it, as shown in FIG. 5, the fixing part 12 of the hollow fiber membrane module M is is airtightly attached to the lid body 21 having the outlet 23 for the filtered fluid, and the thread membrane module M is installed. It is housed in a cup-shaped container 20 equipped with an inlet 22 for the fluid to be treated, and the container 20 and the lid are connected together. The butt flange part with 21 is airtightly and removably connected with the tightening band 24. do.
【００１０】 そして、被処理流体を入口２２から所要圧力のもとに容器２０内に流入させれ ば、被処理流体は中空糸膜モジュールＭの側周及びサンドイッチシートの巻き込 みすき間から通気性のシート状物１３，１４を通り抜け、かつ並列する中空糸膜 １１を透過し、ろ過されて各糸膜１１の内部を通り、蓋体２１の出口２３から流 出していく。その間に流体中に混入している不純物等の微粒子は各中空糸膜１１ により捕捉され、その表面に付着して被処理流体から分離される。0010 Then, the fluid to be treated is caused to flow into the container 20 from the inlet 22 under a required pressure. For example, the fluid to be treated is around the side of the hollow fiber membrane module M and wrapped around the sandwich sheet. The hollow fiber membranes pass through the air permeable sheet-like materials 13 and 14 through the gap and are arranged in parallel. 11, is filtered, passes through the inside of each thread membrane 11, and flows from the outlet 23 of the lid body 21. I'll bring it out. During this time, fine particles such as impurities mixed in the fluid are removed from each hollow fiber membrane 11. is captured by the fluid, adheres to its surface, and is separated from the fluid to be treated.
【００１１】 その際、各中空糸膜１１の一端（図で下端）は密封部１５により前後の通気性 シート状物１３，１４に一体に固着され、かつ全長にわたって前後の通気性シー ト状物１３，１４によって整列状態に保持されているため、中空糸膜１１同士の すき間は一定に保たれ、流体の流れの片寄りが防止され、いわゆるチャンネル現 象を生じない。[0011] At that time, one end (lower end in the figure) of each hollow fiber membrane 11 is provided with a sealing part 15 to ensure ventilation between the front and rear. It is integrally fixed to the sheet-like materials 13 and 14, and has a front and rear breathable sheet along the entire length. Since the hollow fiber membranes 11 are held in an aligned state by the tabs 13 and 14, The gap is kept constant and the fluid flow is prevented from shifting, creating a so-called channel effect. does not cause an elephant.
【００１２】 なお、固定部１２の形成に先立って、この端部も予め熱融着しておけば、中空 糸膜１１のほつれが確実に防止される。一方芯棒１６はシートの巻き込みに便利 なためで、省略しても差支えない。また、中空糸膜１１の素材としては前記のも のの他にポリスルホン，ポリエチレン，ポリアミド，アセチルセルロース，弗素 樹脂等が用いられ、固定用の樹脂としては前記のものの他にエポキシ系．ウレタ ン系の樹脂が用いられる。0012 Note that if this end is also heat-sealed in advance before forming the fixing part 12, the hollow The fraying of the thread membrane 11 is reliably prevented. On the other hand, the core rod 16 is convenient for winding the sheet. Therefore, it can be omitted. In addition, as the material for the hollow fiber membrane 11, the above-mentioned materials are also used. In addition to polysulfone, polyethylene, polyamide, acetylcellulose, fluorine In addition to the above-mentioned resins, epoxy resins are used as fixing resins. Ureta A resin based on the resin is used.
【００１３】 以上のようにこの考案は、流体ろ過用の中空糸膜モジュールとして、帯状の通 気性シート状物の上に多数の一定長さの中空糸膜を幅方向に並列させて配設し、 その上に同じ通気性シート状物を重ね合せてサンドイッチシートとなし、その一 端縁を熱融着して中空糸膜の密封部を形成し、このサンドイッチシートをスパイ ラルに巻き込み、この巻き込みロール体の一端部を合成樹脂により固定し、この 固定部を切断してその切口端面に各中空糸膜を開口させたので、多数の中空糸膜 の一端は前後の通気性シート状物と一体で、そして、中空糸膜は全長にわたって 通気性シート状物により保持されるため、各中空糸膜同士のすき間を均一に保つ ことができ、使用時における流体のチャンネル現象を確実に防ぐことができ、デ ッドスペースを作ることなくモジュールの機能を低下させない。 また、多数の中空糸膜を保持するシート状物は通気性のものなので、被処理流 体を円滑に処理することができる。[0013] As mentioned above, this idea is a hollow fiber membrane module for fluid filtration. A large number of hollow fiber membranes of a certain length are arranged in parallel in the width direction on top of a pneumatic sheet-like material, Layer the same breathable sheet material on top of it to make a sandwich sheet, and The edges are heat-sealed to form a sealed part of the hollow fiber membrane, and this sandwich sheet is Roll it up into a roll, fix one end of this roll body with synthetic resin, and Since the fixing part was cut and each hollow fiber membrane was opened at the cut end, a large number of hollow fiber membranes could be formed. One end is integrated with the front and rear breathable sheet materials, and the hollow fiber membrane extends over the entire length. The gap between each hollow fiber membrane is maintained evenly because it is held by a breathable sheet material. can reliably prevent fluid channel phenomenon during use, and does not reduce module functionality without creating head space. In addition, since the sheet-like material holding a large number of hollow fiber membranes is breathable, The body can be processed smoothly.
