Description
【０００１】[0001]
本考案は、純水，用水，食品，製薬等の製造プロセスや排水処理において、原 液から固形物質等を分離する場合に使用する外圧型中空糸膜モジュ−ルに関する ものである。 The present invention relates to an external pressure type hollow fiber membrane module used when separating a solid substance or the like from an undiluted solution in a manufacturing process such as pure water, water, food, pharmaceuticals, etc. and wastewater treatment.
【０００２】[0002]
純水，用水，食品，製薬等の製造プロセスや排水処理において、原液から固形 物質等を分離する場合、近来においては、膜モジュ−ルを使用することが多い。 膜モジュ−ル中、中空糸膜を用いたモジュ−ルにおいては、単位容積当たりの 膜面積を大きくできるのでモジュ−ルをコンパクト化できる、縦型設置の場合、 単位設置スペ−ス当たりの処理能力を大きくできる等、多くの点で有利である。 In the production process of pure water, water, foods, pharmaceuticals, etc. and wastewater treatment, when separating solid substances from the undiluted solution, membrane modules are often used recently. Among the membrane modules, in the module using a hollow fiber membrane, the membrane area per unit volume can be increased so that the module can be made compact. In the case of vertical installation, treatment per unit installation space It is advantageous in many ways, such as increasing the capacity.
【０００３】 この中空糸膜モジュ−ルの中でも、外圧型モジュ−ルが、内圧型に較べて、懸 濁物質成分を含む原液に対する流通路詰りが生じ難いので有利であり、特に、懸 濁物質成分濃度が高い原液に対しては、クロスフロ−濾過方式を使用することに より、原液流の膜面洗浄作用で膜面への懸濁物質成分の付着を低減でき、外圧型 中空糸膜モジュ−ルをクロスフロ−濾過方式で使用することが多い。Among the hollow fiber membrane modules, the external pressure type module is advantageous as compared with the internal pressure type module because it is less likely to cause clogging of the flow passage for the stock solution containing the suspended matter component, and particularly, the suspended substance For a stock solution with a high concentration of components, the cross-flow filtration method can be used to reduce the adhesion of suspended solids to the membrane surface by the action of cleaning the membrane surface of the stock solution flow. Is often used in a cross-flow filtration system.
【０００４】 このクロスフロ−濾過方式で外圧型中空糸膜モジュ−ルを使用する場合、中空 糸膜束全体に対し原液を一様に流動させ、原液流による膜面洗浄を中空糸膜束全 体に対して均一に行なうことが重要である。When the external pressure type hollow fiber membrane module is used in this cross-flow filtration method, the stock solution is uniformly flowed through the entire hollow fiber membrane bundle, and the membrane surface is washed by the stock solution flow as a whole. It is important to do this uniformly.
【０００５】 図３はクロスフロ−濾過方式を使用した従来の外圧型中空糸膜モジュ−ルの一 例を示している。 図３において、１’は筒状ケ−ス、２’は筒状ケ−ス１’内に収容された中空 糸膜束である。３’は筒状ケ−ス１’の一端に設けられた樹脂隔壁であり、複数 箇の原液流通用孔４’，…が等間隔で設けられ、中空糸膜束２’の一端部が埋着 されて中空糸膜の一端２１’が樹脂隔壁３’の外面側に開通されている。他方、 中空糸膜の他端２２’は閉塞され、自由状態とされている。１１’は筒状ケ−ス １’の他端に設けられた原液流出口である。５’はヘッダ−であり、隔壁５１’ により原液室ａ’と透過液室ｂ’とに仕切られ、その隔壁５１’に原液流通用管 ６’，…が貫設され、原液室ａ’には原液供給口７１’が、透過液室ｂ’には透 過液取出口７２’がそれぞれ設けられている。FIG. 3 shows an example of a conventional external pressure type hollow fiber membrane module using a cross flow filtration system. In FIG. 3, 1'is a cylindrical case and 2'is a hollow fiber membrane bundle housed in the cylindrical case 1 '. Reference numeral 3'denotes a resin partition wall provided at one end of the tubular case 1 ', and a plurality of stock solution distribution holes 4', ... Are provided at equal intervals, and one end of the hollow fiber membrane bundle 2'is embedded. One end 21 'of the attached hollow fiber membrane is opened to the outer surface side of the resin partition wall 3'. On the other hand, the other end 22 'of the hollow fiber membrane is closed and is in a free state. Reference numeral 11 'is a stock solution outlet provided at the other end of the cylindrical case 1'. Reference numeral 5'denotes a header, which is partitioned by a partition wall 51 'into a stock solution chamber a'and a permeate solution chamber b', and a stock solution flow pipe 6 ', ... Is pierced through the partition wall 51' to form a stock solution chamber a '. Is provided with a stock solution supply port 71 ', and a permeated liquid chamber b'is provided with a permeated liquid outlet 72'.
【０００６】 このヘッダ−５’は筒状ケ−ス１’の一端にＶバンド等により連結されてヘッ ダ−５’内の原液流通用管６’，…が筒状ケ−ス一端の樹脂隔壁３’の原液流通 用孔４’，…にｏリング等を介して連結されている。The header 5'is connected to one end of a cylindrical case 1'by a V band or the like, and the stock solution distribution pipes 6 ', ... In the header 5'are made of resin at one end of the cylindrical case. It is connected to the undiluted solution flow holes 4 ', ... Of the partition wall 3'via an o-ring or the like.
【０００７】 上記外圧型中空糸膜モジュ−ルにおいては、原液がヘッダ−５’の原液供給口 ７１’から供給され、この供給源液が原液室ａ’，原液流通用管６’，原液流通 用孔４’を経て筒状ケ−ス１’内に流入される。In the above external pressure type hollow fiber membrane module, the stock solution is supplied from the stock solution supply port 71 ′ of the header 5 ′, and the supply source solution is supplied to the stock solution chamber a ′, the stock solution distribution pipe 6 ′, and the stock solution distribution. It is flowed into the cylindrical case 1'through the hole 4 '.
【０００８】 この外圧型中空糸膜モジュ−ルにおいては、筒状ケ−ス一端の樹脂隔壁３’の 原液流通用孔４’が複数箇とされ、中空糸膜束２’の断面に対し、よく配分され ているから、原液を中空糸膜束２’内に充分一様に流し得、原液流による膜面洗 浄を中空糸膜束全体に対して充分均一に行なうことができる。In this external pressure type hollow fiber membrane module, a plurality of undiluted solution flow holes 4 ′ of the resin partition wall 3 ′ at one end of the cylindrical case are provided, and the cross section of the hollow fiber membrane bundle 2 ′ is Since it is well distributed, the stock solution can be flowed into the hollow fiber membrane bundle 2 ′ sufficiently uniformly, and the cleaning of the membrane surface by the flow of the stock solution can be performed sufficiently uniformly over the entire hollow fiber membrane bundle.
【０００９】 上記において、原液が中空糸膜束２’内を流動する間、原液中の溶媒が中空糸 膜を透過し、この中空糸膜内の透過液が中空糸膜の一端２１’よりヘッダ−５’ の透過液室ｂ’を経て透過液取出口７２’から取り出されていく。他方、濾過に より溶質濃度が濃縮された原液が筒状ケ−ス他端の原液出口１１’から流出され ていく。In the above, while the stock solution flows in the hollow fiber membrane bundle 2 ′, the solvent in the stock solution permeates the hollow fiber membrane, and the permeated solution in the hollow fiber membrane is transferred from the end 21 ′ of the hollow fiber membrane to the header. It is taken out from the permeated liquid outlet 72 'through the permeated liquid chamber b'of -5'. On the other hand, the stock solution whose solute concentration is concentrated by filtration is discharged from the stock solution outlet 11 'at the other end of the cylindrical case.
【００１０】[0010]
上記の通り、図に示す外圧型中空糸膜モジュ−ルにおいては、原液流による膜 面洗浄を均一に行ない得、中空糸膜束全体に濾過作用を一様に行なわせ得るが、 ヘッダ−５’における原液流通用管６’の本数、従って、筒状ケ−ス一端の樹脂 隔壁３’における原液流通用孔４’の箇数が複数箇であり、原液流通用管６’と 原液流通用孔４’とを複数箇所において位置合わせしなければならず、モジュ− ルの製造時、原液流通用管６’の位置決め並びに原液流通用孔４’の位置決めを 複数箇所において行なう必要があるので、モジュ−ルの製造が容易ではない。 As described above, in the external pressure type hollow fiber membrane module shown in the figure, the membrane surface can be uniformly washed by the undiluted stream, and the entire hollow fiber membrane bundle can be uniformly filtered. There are a plurality of undiluted solution distribution pipes 6'in the tube, and therefore, there are a plurality of undiluted solution distribution holes 4'in the resin partition wall 3'at one end of the cylindrical case. Since it is necessary to align the holes 4'at a plurality of positions, it is necessary to position the undiluted solution flow pipe 6'and the undiluted solution flow hole 4'at a plurality of positions during manufacturing of the module. The manufacture of modules is not easy.
【００１１】 また、原液流通用管６’と原液流通用孔４’との連結箇所が複数箇であるため 、原液側と透過液側との間のＯリング等によるシ−ル箇所の個数が多くなって、 全体的なシ−ルに対する信頼性にも問題がある。Further, since the undiluted solution flow pipe 6 ′ and the undiluted solution flow hole 4 ′ are connected at a plurality of points, the number of seal points due to an O-ring or the like between the undiluted solution side and the permeated solution side is reduced. There is also a problem with the overall reliability of the seal.
【００１２】 本考案の目的は、クロスフロ−濾過方式で使用する外圧型中空糸膜モジュ−ル において、製作が容易で、しかも、原液側と透過液側との間のＯリング等による シ−ル箇所を少なくして信頼性をよく向上できる外圧型中空糸膜モジュ−ルを提 供することにある。An object of the present invention is to provide an external pressure type hollow fiber membrane module for use in a cross flow filtration method, which is easy to manufacture and which is sealed by an O-ring or the like between the raw solution side and the permeated side.

The stock solution distributing member and the one end of the hollow fiber membrane bundle are embedded in the resin partition wall, and the mouth tube part of the distributing member and one end of the hollow fiber membrane are opened to the outer surface side of the resin partition wall and the distribution member is divided. The passage is opened to the inner surface side of the resin partition wall, the other end of the hollow fiber membrane is closed, and a permeated liquid take-out case having a stock solution flow pipe inside is connected to one end of a tubular case. This is a configuration characterized in that the stock solution distribution pipe is connected to the mouth pipe part of the stock solution distribution member.
【００１４】[0014]
筒状ケ−ス一端の樹脂隔壁における原液流通用孔への原液流通用管の連結箇所 が１ヶ所であるので、モジュ−ル製作における原液流通用管の位置決め並びに原 液流通用孔の位置決めがそれぞれ１ヶ所だけとなり、モジュ−ルの製作が容易と なる。 Since there is only one place where the undiluted solution flow pipe is connected to the undiluted solution flow hole in the resin partition wall at one end of the cylindrical case, positioning of the undiluted solution flow pipe and positioning of the undiluted solution flow hole in module manufacturing can be performed. Each has only one location, which facilitates module production.
【００１５】 また、透過液取出用ケ−ス内の透過液と筒状ケ−ス内の原液を遮断するＯリン グ等によるシ−ル箇所が１ヵ所だけとなるので、信頼性が向上する。Further, since there is only one sealing position due to the O-ring or the like for blocking the permeated liquid in the permeated liquid take-out case and the stock solution in the cylindrical case, the reliability is improved. ..
