Connection by the hose 5 can be connected in the shortest time. Further, the height of the frame of the hollow fiber membrane module 2 can be reduced, the unit rack supporting the hollow fiber membrane module 2 can be made compact, and when the unit rack is lifted and suspended in the treatment tank, etc. Easy to handle.
更に、図10に示すように、従来の接続構造と本発明の接続構造を比較すると、本発明の接続構造とすることにより口金３の上部に斜線で示すような自由な空間が出来る。これは、中空糸膜モジュール２の口金３と媒体集合ヘッダー管４の先端部６の互いの軸芯位置がずれて設定されているため、両軸芯間の水平方向の離間間隔Ｚが確保されているためである。このため、浸透膜装置での散気管部の点検をする際に、この自由な空間を利用して中空糸膜モジュール２を上部に持ち上げて容易に点検をすることが出来る。 Furthermore, as shown in FIG. 10, when the connection structure of the present invention is compared with the connection structure of the present invention, by using the connection structure of the present invention, a free space as shown by hatching is formed above the base 3. This is because the axial positions of the base 3 of the hollow fiber membrane module 2 and the tip 6 of the medium assembly header tube 4 are set so as to deviate from each other. This is because. For this reason, when inspecting the air diffusing pipe portion in the osmotic membrane device, the hollow fiber membrane module 2 can be lifted up by using this free space and easily inspected.
また、媒体集合ヘッダー管４の傾斜した先端部６が該媒体集合ヘッダー管４本体に対して回転自在に設けられたことにより中空糸膜モジュール２の口金３と、該口金３に対向する媒体集合ヘッダー管４との互いの軸芯位置３ａ，４ａのずれの程度に対応して媒体集合ヘッダー管４の先端部６の軸芯傾斜角度θを自在に調整することが出来る。 Further, the inclined tip portion 6 of the medium assembly header tube 4 is provided so as to be rotatable with respect to the medium assembly header tube 4 main body, so that the base 3 of the hollow fiber membrane module 2 and the medium assembly opposite to the base 3 are provided. The axis inclination angle θ of the tip end portion 6 of the medium assembly header pipe 4 can be freely adjusted in accordance with the degree of deviation of the axis positions 3a, 4a from the header pipe 4.
本発明では図12に示すように、媒体集合ヘッダー管４の先端部が傾斜されていても良いし、膜モジュールキャップ３ｃに接続される口金３が傾斜されていても良いし、その両方が傾斜されていても構わない。 In the present invention, as shown in FIG. 12, the tip of the medium assembly header tube 4 may be inclined, the base 3 connected to the membrane module cap 3c may be inclined, or both of them are inclined. It does not matter.
また、媒体集合ヘッダー管４を、複数の中空糸膜モジュール２の口金３に接続されるトーナメント構造またはループ構造で構成することにより多数の中空糸膜モジュール２を密に収容することが出来る。図５（ａ）はトーナメント構造の例を、図５（ｂ）はループ構造の例をそれぞれ示す。 Further, by forming the medium assembly header tube 4 in a tournament structure or a loop structure connected to the bases 3 of the plurality of hollow fiber membrane modules 2, a large number of hollow fiber membrane modules 2 can be accommodated densely. FIG. 5A shows an example of a tournament structure, and FIG. 5B shows an example of a loop structure.
この場合に密な収容が出来るためには、図11に示すように、媒体集合ヘッダー管４と口金３との軸芯位置４ａ，３ａをずらす方向は、隣り合った中空糸膜モジュール２間の間隔が狭まる方向である必要がある。すなわち、図11において、Ｌ´≧Ｌを満足する必要がある。 In this case, in order to allow dense accommodation, as shown in FIG. 11, the direction in which the axial positions 4a and 3a of the medium assembly header tube 4 and the base 3 are shifted is set between the adjacent hollow fiber membrane modules 2. The distance needs to be narrowed. That is, in FIG. 11, it is necessary to satisfy L ′ ≧ L.
図６（ａ）では、固定した中空糸膜モジュール２の口金３の中心軸である軸芯位置３ａと、媒体集合ヘッダー管４の中心軸である軸芯位置４ａとを同一直線上に配置させた場合の配管接続形態を示す。この場合、可撓性ホース５を用いて口金３と媒体集合ヘッダー管４とを接続しようとすると、口金３に該可撓性ホース５を差し込むために該可撓性ホース５をある程度撓ませて接続することになる。そのため、該可撓性ホース５の長さは撓ませる分だけ余分に長くする必要がある。また、このときの撓みによる屈曲部は３ヶ所となり、該可撓性ホース５を屈曲させて接続させる際に、屈曲部分に反力が生じ接続し難くなる。従って、該屈曲部分に発生する反力は図６（ｂ）〜（ｄ）に示す他の配管接続形態に比べて大きくなる。また、接続の際、中空糸膜モジュール２と媒体集合ヘッダー管４に曲げ応力を生じ、該媒体集合ヘッダー管４が変形したり破壊したりすることが懸念される。この懸念を解消するためには、該媒体集合ヘッダー管４に重厚な補強が必要になる。また、可撓性ホース５が樹脂製ホースの場合には曲がり癖（くせ）が付き易いという問題がある。 In FIG. 6A, the axial center position 3a that is the central axis of the cap 3 of the fixed hollow fiber membrane module 2 and the axial center position 4a that is the central axis of the medium assembly header pipe 4 are arranged on the same straight line. Shows the pipe connection configuration. In this case, when the base 3 and the medium assembly header pipe 4 are to be connected using the flexible hose 5, the flexible hose 5 is bent to some extent in order to insert the flexible hose 5 into the base 3. Will be connected. Therefore, it is necessary to make the length of the flexible hose 5 longer than the length of the flexible hose 5 to be bent. Further, there are three bent portions due to the bending at this time, and when the flexible hose 5 is bent and connected, a reaction force is generated in the bent portion and it is difficult to connect. Therefore, the reaction force generated at the bent portion is larger than the other pipe connection forms shown in FIGS. Further, when connecting, there is a concern that bending stress is generated in the hollow fiber membrane module 2 and the medium assembly header tube 4, and the medium assembly header tube 4 is deformed or broken. In order to eliminate this concern, the medium assembly header pipe 4 needs to be heavily reinforced. Further, when the flexible hose 5 is a resin hose, there is a problem that it is easy to bend.
図６（ｂ）では、固定した中空糸膜モジュール２の口金３の中心軸である軸芯位置３ａと、媒体集合ヘッダー管４の中心軸である軸芯位置４ａとをずらして水平方向の離間距離Ｚを確保した場合の配管接続形態を示す。離間距離Ｚの寸法分だけ可撓性ホース５の全長は長くなるが、該可撓性ホース５は緩やかな曲げ半径を取ることが出来るため、可撓性ホース５に発生する反力が図６（ａ）に示す配管接続形態と比べて小さく可撓性ホース５の接続は容易である。 In FIG. 6B, the axial position 3a that is the central axis of the cap 3 of the fixed hollow fiber membrane module 2 and the axial position 4a that is the central axis of the medium assembly header pipe 4 are shifted to be separated in the horizontal direction. The piping connection form when the distance Z is secured is shown. Although the total length of the flexible hose 5 is increased by the dimension of the separation distance Z, since the flexible hose 5 can take a gentle bending radius, the reaction force generated in the flexible hose 5 is shown in FIG. The flexible hose 5 is small and easy to connect as compared to the pipe connection form shown in FIG.
しかしながら、図６（ｂ）の方法では屈曲部が２箇所となるため、該可撓性ホース５の長さを最短にすることが出来ないだけでなく、曲がり管内部を流通する流体の流線に渦を生じさせ、配管内の管摩擦抵抗による圧力損失を上昇させる恐れがある。 However, in the method of FIG. 6 (b), since there are two bent portions, not only the length of the flexible hose 5 cannot be minimized, but also the streamline of the fluid that circulates inside the bent pipe May cause vortices to increase pressure loss due to pipe frictional resistance in the pipe.
図６（ｃ）では、固定した中空糸膜モジュール２の口金３の中心軸である軸芯位置３ａと、媒体集合ヘッダー管４の中心軸である軸芯位置４ａとを一致させ、媒体集合ヘッダー管４の先端部６を傾斜させた配管接続形態を示す。この場合、可撓性ホース５の接続は容易であるが、媒体集合ヘッダー管４の先端部６の軸芯傾斜角度θ次第では、可撓性ホース５に発生する反力は大きくなり、該可撓性ホース５の全長も曲げ戻す分長くなる。尚、図６（ｃ）に示す配管接続形態では、図６（ａ），（ｂ），（ｄ）に示す他の配管接続形態に比べて可撓性ホース５の長さは最も長くなる。 In FIG. 6 (c), the axial center position 3a that is the central axis of the base 3 of the fixed hollow fiber membrane module 2 and the axial center position 4a that is the central axis of the medium assembly header pipe 4 are made to coincide with each other. The pipe connection form which inclined the front-end | tip part 6 of the pipe | tube 4 is shown. In this case, the connection of the flexible hose 5 is easy, but the reaction force generated in the flexible hose 5 becomes large depending on the inclination angle θ of the axial center of the front end portion 6 of the medium assembly header tube 4. The total length of the flexible hose 5 is also lengthened by bending back. In addition, in the piping connection form shown in FIG.6 (c), the length of the flexible hose 5 becomes the longest compared with the other piping connection form shown in FIG.6 (a), (b), (d).
本発明の実施態様の１つである図６（ｄ）では、固定した中空糸膜モジュール２の口金３の中心軸である軸芯位置３ａと、媒体集合ヘッダー管４の中心軸である軸芯位置４ａとをずらして水平方向の離間距離を確保し、更に媒体集合ヘッダー管４の先端部６を傾斜させた配管接続形態を示す。 In FIG. 6 (d) which is one embodiment of the present invention, an axial center position 3 a which is the central axis of the cap 3 of the fixed hollow fiber membrane module 2 and an axial core which is the central axis of the medium assembly header pipe 4. A pipe connection form in which the horizontal separation distance is ensured by shifting the position 4a and the front end portion 6 of the medium assembly header pipe 4 is inclined is shown.
媒体集合ヘッダー管４の先端部６の軸芯角度θを図６（ｄ）に示すように適切な角度に傾斜させ、可撓性ホース５の最小曲げ半径で接続できるようにすることで、該可撓性ホース５の屈曲部を１箇所だけとすることが出来る。そうすると、該可撓性ホース５は滑らかに接続することが出来るため、該可撓性ホース５のひずみが小さく、癖が付き難い。しかも可撓性ホース５の長さを最短とすることが出来、中空糸膜モジュール２の口金３と、媒体集合ヘッダー管４との高さ方向の離間間隔Ｈを短くすることが出来ることから、浸漬濾過装置１の背丈を低く出来、かつコンパクト化が可能となる。また、曲がり管部の配管内の管摩擦抵抗による圧力損失は図６（ｂ）に比べて低減できる。 By tilting the axis angle θ of the front end portion 6 of the medium assembly header pipe 4 to an appropriate angle as shown in FIG. 6D, the flexible hose 5 can be connected with the minimum bending radius, Only one bent portion of the flexible hose 5 can be provided. Then, since the flexible hose 5 can be connected smoothly, the distortion of the flexible hose 5 is small and it is difficult to be wrinkled. In addition, the length of the flexible hose 5 can be minimized, and the distance H in the height direction between the base 3 of the hollow fiber membrane module 2 and the medium assembly header pipe 4 can be shortened. The height of the immersion filtration device 1 can be reduced and the size can be reduced. Further, the pressure loss due to the pipe frictional resistance in the pipe of the bent pipe portion can be reduced as compared with FIG.
更に、図６（ｄ）の形態で該可撓性ホース５を接続する際、該可撓性ホース５の弾性力を利用することで、小さな力で中空糸膜モジュール２の口金３と媒体集合ヘッダー管４の先端部６とを連結することができる。 Further, when the flexible hose 5 is connected in the form of FIG. 6D, the base 3 and the medium assembly of the hollow fiber membrane module 2 can be used with a small force by utilizing the elastic force of the flexible hose 5. The tip 6 of the header pipe 4 can be connected.
本発明でいう、媒体集合ヘッダー管４の先端部６が可撓性ホース５の最小曲げ半径以上の曲げ半径で接続を可能とし得る角度に傾斜された状態とは、次のように調節することが出来る。例えば、可撓性ホース５の長さを長くした場合には、先端部６の軸芯傾斜角度θを大きくするか、若しくは中空糸膜モジュール２の口金３の中心軸である軸芯位置３ａと、媒体集合ヘッダー管４の中心軸である軸芯位置４ａとの水平方向の離間間隔Ｚを大きくすることで調節出来る。 According to the present invention, the state in which the front end portion 6 of the medium assembly header pipe 4 is inclined at an angle that enables connection at a bending radius greater than the minimum bending radius of the flexible hose 5 is adjusted as follows. I can do it. For example, when the length of the flexible hose 5 is increased, the axis tilt angle θ of the tip 6 is increased, or the axis position 3a that is the center axis of the base 3 of the hollow fiber membrane module 2 The distance Z in the horizontal direction from the axial center position 4a that is the central axis of the medium assembly header tube 4 can be adjusted.
次に図７を用いて図６（ｂ），（ｄ）に示す配管接続形態の中空糸膜モジュール２の口金３と、媒体集合ヘッダー管４との垂直方向の離間間隔Ｈの比較と、媒体集合ヘッダー管４の先端部６の軸芯傾斜角度θの設定について説明する。図７に示すように、媒体集合ヘッダー管４の軸芯位置４ａと、中空糸膜モジュール２の口金３の軸芯位置３ａとの水平方向の離間間隔Ｚを確保した状態で、可撓性ホース５を最小曲げ半径で接続するための媒体集合ヘッダー管４の先端部６の軸芯傾斜角度θは、中空糸膜モジュール２の口金３の接続口先端３ｂに水平線ａを引いて、可撓性ホース５が描く円弧の開始点を中空糸膜モジュール２の口金３の接続口先端３ｂとし、該可撓性ホース５の最小曲げ半径Ｒを設定する。 Next, with reference to FIG. 7, a comparison of the vertical separation distance H between the base 3 of the hollow fiber membrane module 2 having the pipe connection configuration shown in FIGS. 6B and 6D and the medium assembly header pipe 4, and the medium The setting of the axis inclination angle θ of the distal end portion 6 of the collective header pipe 4 will be described. As shown in FIG. 7, the flexible hose is secured in a state in which a horizontal separation distance Z between the axial center position 4 a of the medium assembly header pipe 4 and the axial center position 3 a of the base 3 of the hollow fiber membrane module 2 is secured. The axis inclination angle θ of the front end portion 6 of the medium assembly header tube 4 for connecting the members 5 with the minimum bending radius is determined by drawing a horizontal line a to the connection port front end 3b of the base 3 of the hollow fiber membrane module 2. The starting point of the circular arc drawn by the hose 5 is the connection port tip 3b of the base 3 of the hollow fiber membrane module 2, and the minimum bending radius R of the flexible hose 5 is set.
媒体集合ヘッダー管４の先端部６の中心軸である軸芯位置６ａ上で接続口先端６ｂを通る水平線ｂを引き、可撓性ホース５の最小曲げ半径Ｒの中心点Ｏと、媒体集合ヘッダー管４の先端部６の軸芯位置６ａ上で接続口先端６ｂとを通り該軸芯位置６ａと直交する直線ｃを引くことが出来、該直線ｃと、前記水平線ａとが成す角度θが求められる。即ち、この角度θが媒体集合ヘッダー管４の先端部６の軸芯傾斜角度θである。傾斜角度θは、水平線ａ，ｂが平行であるため同位角で等しい。 A horizontal line b passing through the connection port front end 6b is drawn on the axial center position 6a which is the central axis of the front end portion 6 of the medium assembly header pipe 4, and the center point O of the minimum bending radius R of the flexible hose 5 and the medium assembly header A straight line c passing through the connection port tip 6b on the axial position 6a of the distal end portion 6 of the tube 4 and perpendicular to the axial position 6a can be drawn, and an angle θ formed by the straight line c and the horizontal line a is Desired. That is, this angle θ is the axial center inclination angle θ of the tip portion 6 of the medium assembly header tube 4. Since the horizontal lines a and b are parallel, the inclination angle θ is equal in the isotope angle.
ここで、媒体集合ヘッダー管４の軸芯位置４ａと中空糸膜モジュール２の口金３の軸芯位置３ａとの水平方向の離間間隔をＺ、中空糸膜モジュール２の口金３と媒体集合ヘッダー管４との垂直方向の離間間隔をＨ、中空糸膜モジュール２の口金３と媒体集合ヘッダー管４との垂直方向の離間間隔Ｈを最短としたときの該Ｈ寸法との差をΔＨ、可撓性ホース５の最小曲げ半径をＲ、可撓性ホース５が形成する円弧の中心角をθ、可撓性ホース５が形成する円弧の長さ（可撓性ホース５の長さ）をＬ、可撓性ホース５両端部の接続代の長さをＬＣとすると、可撓性ホース５の長さＬ＝π×Ｒ×（θ／１８０）＋２×ＬＣで表すことが出来る。 Here, the distance in the horizontal direction between the axis position 4a of the medium assembly header tube 4 and the axis position 3a of the base 3 of the hollow fiber membrane module 2 is Z, and the base 3 of the hollow fiber membrane module 2 and the medium assembly header pipe 4 is H, and the difference between the vertical dimension H between the base 3 of the hollow fiber membrane module 2 and the medium assembly header pipe 4 is ΔH, and the flexibility is ΔH. The minimum bending radius of the flexible hose 5 is R, the central angle of the arc formed by the flexible hose 5 is θ, the length of the arc formed by the flexible hose 5 (the length of the flexible hose 5) is L, If the length of the connection allowance at both ends of the flexible hose 5 is LC, the length of the flexible hose 5 can be expressed as L = π × R × (θ / 180) + 2 × LC.
尚、前記実施形態では、図８（ａ）に示すように、中空糸膜モジュール２が浸漬槽17の液中に起立した状態で浸漬される濾過液減圧式の浸漬膜型濾過装置に適用した場合の一例について説明したが、図８（ｂ）に示すように、中空糸膜モジュール２を密閉タンク18内に収容し、該密閉タンク18内に原液を加圧送入するか若しくは濾過液を減圧吸引して濾過するタンク型濾過装置にも適用出来、更には、図９（ａ）に示すように、外筒ケース19内に収容された中空糸膜モジュール２で中空糸膜の内側から原液を濾過する内圧型膜モジュール構造と、図９（ｂ）に示すように、中空糸膜の外側から原液を濾過する外圧型膜モジュール構造において、原液を加圧挿入するか若しくは濾過液を減圧吸引する方法を持つ種々の濾過装置にも適用可能である。尚、図８中、20はスカート部、21は散気管である。 In addition, in the said embodiment, as shown to Fig.8 (a), it applied to the submerged membrane type filtration apparatus of the filtrate depressurization type in which the hollow fiber membrane module 2 is immersed in the state which stood up in the liquid of the immersion tank 17. Although an example of the case has been described, as shown in FIG. 8 (b), the hollow fiber membrane module 2 is accommodated in the sealed tank 18, and the stock solution is pressurized and fed into the sealed tank 18 or the filtrate is depressurized. It can also be applied to a tank-type filtration device that sucks and filters. Furthermore, as shown in FIG. 9A, the hollow fiber membrane module 2 accommodated in the outer cylinder case 19 can be used to remove the stock solution from the inside of the hollow fiber membrane. In the internal pressure type membrane module structure to be filtered and the external pressure type membrane module structure in which the stock solution is filtered from the outside of the hollow fiber membrane as shown in FIG. 9B, the stock solution is inserted under pressure or the filtrate is sucked under reduced pressure. Applicable to various filtration devices with methodIn FIG. 8, 20 is a skirt portion and 21 is an air diffuser.
図13は、加圧型モジュールに本発明を適用した場合において、可撓性ホース５を用いた接続方法の一例である。 FIG. 13 is an example of a connection method using the flexible hose 5 when the present invention is applied to a pressure type module.
尚、前記実施形態では、複数の中空糸膜モジュール２に媒体集合ヘッダー管４を接続する場合に適用した構成について説明したが、該媒体集合ヘッダー管４の代わりに媒体注入ヘッダー管を複数の中空糸膜モジュール２に接続する場合も同様な構成とすることが出来る。その際には、前述と同様に、媒体注入ヘッダー管の傾斜した先端部を該媒体注入ヘッダー管本体に対して回転自在に設けることが出来る。 In the above embodiment, the configuration applied when the medium assembly header tube 4 is connected to the plurality of hollow fiber membrane modules 2 has been described. However, instead of the medium assembly header tube 4, a medium injection header tube is replaced with a plurality of hollow tubes. The same configuration can be adopted when connecting to the yarn membrane module 2. In this case, as described above, the inclined tip portion of the medium injection header pipe can be rotatably provided with respect to the medium injection header pipe main body.
上記構成により、膜濾過装置の膜面積と据付面積との比が４００〜１１００の範囲となる膜分離ユニットとして構成できる。 By the said structure, it can comprise as a membrane separation unit from which the ratio of the membrane area of a membrane filtration apparatus and an installation area becomes the range of 400-1100.
