Description
本発明は、中空糸膜モジュールに関する。さらに詳しくは、中空糸膜群を収容している束着管を、シール部材を介してハウジングへ装着せしめた中空糸膜モジュールに関する。
The present invention relates to a hollow fiber membrane module. More specifically, the present invention relates to a hollow fiber membrane module in which a bundled tube containing a hollow fiber membrane group is attached to a housing via a seal member.
現在、多孔質セラミックス中空糸膜、多孔質炭素中空糸膜などの多孔質中空糸膜は、液体分離膜、気体分離膜として有効に用いられている。このような多孔質中空糸膜を使用する場合には、これらを固定し、密封する必要があり、そのために多孔質セラミックス中空糸膜群を束着管端部に嵌装させた貫通孔穿設平板の貫通孔に挿入し、貫通孔穿設平板の外面側をガラスシール材で被覆した多孔質セラミックス中空糸膜モジュールなどが、先に本出願人によって提案されている。ここで束着管は、基本的には円筒形なので、ハウジング内周表面に設けられたシール部材嵌装用の溝にシール部材であるOリングを配し、ハウジング装着時のシールを行っている(特許文献１～２)。
Currently, porous hollow fiber membranes such as porous ceramic hollow fiber membranes and porous carbon hollow fiber membranes are effectively used as liquid separation membranes and gas separation membranes. When using such a porous hollow fiber membrane, it is necessary to fix and seal them, and for this purpose, a through-hole drilling in which a porous ceramic hollow fiber membrane group is fitted to the bundled tube end The present applicant has previously proposed a porous ceramic hollow fiber membrane module or the like that is inserted into a through hole of a flat plate and the outer surface side of the through hole drilled flat plate is covered with a glass sealing material. Here, since the bundled tube is basically cylindrical, an O-ring as a seal member is disposed in a groove for fitting a seal member provided on the inner peripheral surface of the housing, and sealing is performed when the housing is mounted ( Patent Documents 1 and 2).
ここで、モジュールをハウジングに装着するに際しては、シール部材の締付力を受けながらモジュールをハウジング内に挿入する必要がある。このような円筒形外周面でのシール部材としては、一般にOリング等が用いられるが、例えば図４～５に示されるようにハウジングへの束着管挿入前(図４)の状態から挿入後(図５)の状態にかけて、Oリング１はOリング２がシールすることとなるシール部位を通過することとなる。このためモジュールの挿入時の装着性が悪く、その結果Oリングが捩れるなどして、シール性を低下させるという問題を生じるおそれがある。このことは、束着管外周表面ではなくハウジング内周表面にシール部材嵌装用の溝を２箇所設けた場合も同様である。
Here, when the module is mounted in the housing, it is necessary to insert the module into the housing while receiving the tightening force of the seal member. An O-ring or the like is generally used as a seal member on such a cylindrical outer peripheral surface. For example, as shown in FIGS. 4 to 5, after the insertion from the state before the bundled tube is inserted into the housing (FIG. 4). In the state shown in FIG. 5, the O-ring 1 passes through the seal portion where the O-ring 2 is to be sealed. For this reason, the mounting property at the time of insertion of the module is poor, and as a result, the O-ring may be twisted, which may cause a problem that the sealing property is deteriorated. This is the same when two grooves for fitting the seal member are provided not on the outer peripheral surface of the bundled tube but on the inner peripheral surface of the housing.
ここで、図６～７に示されるようにOリング１よりもOリング２の径を大きくし、図６に示されるハウジングへの束着管の挿入途中まで、すなわちOリング１がOリング２のシール部位を通過する際の挿入抵抗をなくし、最終的にハウジングへの束着管挿入後(図７)の状態とすることで装着性を向上することも考えられる。しかしながら、より大きな径のOリングに対しては、ハウジング内により大きなスペースが必要となり、またコストに関しても同じ径サイズのOリングを使用するときと比較して高くなってしまう。
Here, the diameter of the O-ring 2 is made larger than that of the O-ring 1 as shown in FIGS. 6 to 7, and until the bundled tube is inserted into the housing shown in FIG. It is also conceivable to improve the mountability by eliminating the insertion resistance when passing through the sealing portion and finally setting the bundled tube into the housing (FIG. 7). However, for a larger diameter O-ring, a larger space is required in the housing, and the cost is higher than when an O-ring having the same diameter is used.
本発明の目的は、同一のシール部材、例えば同じ径サイズのOリングを使用したうえで、ハウジングへの装着性を改善せしめたハウジング装着中空糸膜モジュールを提供することにある。
An object of the present invention is to provide a housing-attached hollow fiber membrane module in which the same seal member, for example, an O-ring having the same diameter size, is used and the mounting property to the housing is improved.
かかる本発明の目的は、中空糸膜を収容した束着管からなる中空糸膜モジュールを、ハウジングの一端に設けられた中空糸膜モジュール挿入部より挿入させ、束着管外周面と束着管を収容するハウジング内周面との間隙に同一のシール部材を少なくとも２個配してハウジングに装着せしめたハウジング装着中空糸膜モジュールにおいて、
ハウジングの中空糸膜モジュール挿入部とは反対側に位置する端部の内周表面およびハウジングの中空糸膜モジュール挿入部側に位置する端部に対応する束着管外周表面にそれぞれ設けられたシール部材嵌装用の溝にシール部材をそれぞれ嵌装せしめることによって、中空糸膜モジュールをハウジングに装着せしめたハウジング装着中空糸膜モジュールによって達成される。 An object of the present invention is to insert a hollow fiber membrane module composed of a bundled tube containing a hollow fiber membrane through a hollow fiber membrane module insertion portion provided at one end of a housing, so that the outer peripheral surface of the bundled tube and the bundled tube are inserted. In the housing-attached hollow fiber membrane module in which at least two identical seal members are arranged in the gap between the housing inner peripheral surface and the housing, and the housing is attached to the housing.
Seals provided on the inner peripheral surface of the end located on the opposite side to the hollow fiber membrane module insertion portion of the housing and on the outer peripheral surface of the bundled tube corresponding to the end located on the hollow fiber membrane module insertion portion side of the housing This is achieved by the housing-mounted hollow fiber membrane module in which the hollow fiber membrane module is mounted on the housing by mounting the seal members in the member mounting grooves.
ハウジングの中空糸膜モジュール挿入部とは反対側に位置する端部の内周表面およびハウジングの中空糸膜モジュール挿入部側に位置する端部に対応する束着管外周表面にそれぞれ設けられたシール部材嵌装用の溝にシール部材をそれぞれ嵌装せしめることによって、中空糸膜モジュールをハウジングに装着せしめたハウジング装着中空糸膜モジュールによって達成される。 An object of the present invention is to insert a hollow fiber membrane module composed of a bundled tube containing a hollow fiber membrane through a hollow fiber membrane module insertion portion provided at one end of a housing, so that the outer peripheral surface of the bundled tube and the bundled tube are inserted. In the housing-attached hollow fiber membrane module in which at least two identical seal members are arranged in the gap between the housing inner peripheral surface and the housing, and the housing is attached to the housing.
Seals provided on the inner peripheral surface of the end located on the opposite side to the hollow fiber membrane module insertion portion of the housing and on the outer peripheral surface of the bundled tube corresponding to the end located on the hollow fiber membrane module insertion portion side of the housing This is achieved by the housing-mounted hollow fiber membrane module in which the hollow fiber membrane module is mounted on the housing by mounting the seal members in the member mounting grooves.
本発明に係るハウジング装着中空糸膜モジュールは、多孔質セラミックス中空糸膜、多孔質炭素中空糸膜等の中空糸膜を収容した束着管からなる中空糸膜モジュールを、束着管外周面とハウジング内周面との間隙にシール部材を少なくとも２個配してハウジングに装着せしめるに際し、シール部材をいずれも同一のもの、すなわち同じ形状およびサイズとすることによって、省スペース化の維持およびコスト増加の回避を達成している。
The housing-attached hollow fiber membrane module according to the present invention comprises a hollow fiber membrane module comprising a bundled tube containing hollow fiber membranes such as a porous ceramic hollow fiber membrane and a porous carbon hollow fiber membrane, and an outer peripheral surface of the bundled tube. When installing at least two seal members in the gap with the inner peripheral surface of the housing and mounting them on the housing, the same seal member is used, that is, the same shape and size, thereby maintaining space saving and increasing costs. Has achieved avoidance.
また、一方のシール部材嵌装用の溝をハウジングの中空糸膜モジュール挿入部とは反対側に位置する端部の内周表面に設け、他方のシール部材嵌装用の溝を中空糸膜モジュール挿入部側に位置する端部に対応する束着管外周表面に設けることによって、ハウジングへ中空糸膜モジュールを装着する際の挿入抵抗を減らし、また挿入回数増加による抵抗によって生ずるシール部材の変形、破損等を防止して、中空糸膜モジュールを何回か交換して使用する場合にあっても、そのシール性を維持せしめるといったすぐれた効果を奏する。
Also, one groove for fitting the seal member is provided on the inner peripheral surface of the end located on the opposite side of the hollow fiber membrane module insertion portion of the housing, and the other groove for fitting the seal member is provided on the hollow fiber membrane module insertion portion. By providing it on the outer peripheral surface of the bundled tube corresponding to the end located on the side, the insertion resistance when mounting the hollow fiber membrane module to the housing is reduced, and the deformation or breakage of the seal member caused by the resistance due to the increased number of insertions Even when the hollow fiber membrane module is used after being replaced several times, the excellent sealing effect can be obtained.
ハウジング装着中空糸膜モジュールは、図１～３に示されるように中空糸膜３を収容した束着管４からなる中空糸膜モジュール５を、束着管４の外周面とハウジング６の内周面との間隙にOリング等のシール部材を少なくとも２個配してハウジング６に装着せしめて構成される。中空糸膜モジュールをハウジングに装着する一態様を図１～２に示す。図１は中空糸膜モジュールをハウジングに挿入している途中の状態を示し、図２は挿入後の状態を示している。ここでハウジング６としては、図１～２に示される中空糸膜モジュール５全体をその管内に収容することができる一体型のハウジングのほか、図３に示されるような中空糸膜モジュール５の両端部を別々に収容するといった分割型のハウジングのいずれも用いることができる。
As shown in FIGS. 1 to 3, the housing-mounted hollow fiber membrane module includes a hollow fiber membrane module 5 including a bundled tube 4 containing the hollow fiber membrane 3. At least two sealing members such as O-rings are arranged in the gap with the surface and are mounted on the housing 6. One embodiment of mounting the hollow fiber membrane module on the housing is shown in FIGS. FIG. 1 shows a state in the middle of inserting the hollow fiber membrane module into the housing, and FIG. 2 shows a state after the insertion. Here, as the housing 6, in addition to an integral housing that can accommodate the entire hollow fiber membrane module 5 shown in FIGS. 1 and 2 in the tube, both ends of the hollow fiber membrane module 5 as shown in FIG. Any of the divided housings can be used in which the parts are accommodated separately.
シール部材としては同一の形状およびサイズのものが用いられ、ここではOリング１，２として同じ径サイズ(断面径および内径)のものが用いられている。シール部材をいずれも同一とすることによって、ハウジング内の省スペース化の維持および異なる形状あるいはサイズのシール部材を用いることによるコストの増加を回避することが可能となる。
The seal member has the same shape and size, and here, the O- rings 1 and 2 have the same diameter (cross-sectional diameter and inner diameter). By making all the sealing members the same, it becomes possible to maintain the space saving in the housing and avoid an increase in cost due to the use of sealing members having different shapes or sizes.
図１～２に示される一体型のハウジングにあっては、中空糸膜モジュール挿入部７とは反対側に位置するハウジング他端部９の内周表面およびハウジング中空糸膜モジュール挿入部７側に位置するハウジング一端部８に対応する束着管外周表面にそれぞれシール部材嵌装用の溝が設けられる。Oリング１、２を収容するいずれの溝も寸法、すなわち溝深さと溝幅は同じであり、ハウジング他端部９に設けられる溝はハウジング内周表面を凹ませることにより形成され、一方ハウジング一端部８に設けられる溝は束着管外周表面に凹部を有する出張り部を設けることにより形成される。これらの図において、Oリング１，２嵌装用の溝の深さは、Oリング１，２のゴム断面の直径よりも小さく設定されており、これによって中空糸膜モジュール５をハウジング６に水密状態で装着させることが可能となる。
In the integrated housing shown in FIGS. 1 and 2, on the inner peripheral surface of the other end 9 of the housing located on the side opposite to the hollow fiber membrane module insertion portion 7 and on the housing hollow fiber membrane module insertion portion 7 side. A groove for fitting a seal member is provided on the outer peripheral surface of the bundled tube corresponding to the housing one end 8 located. Each of the grooves for receiving the O- rings 1 and 2 has the same dimensions, that is, the groove depth and the groove width, and the groove provided in the other end 9 of the housing is formed by denting the inner peripheral surface of the housing. The groove provided in the portion 8 is formed by providing a protruding portion having a recess on the outer peripheral surface of the bundled tube. In these figures, the depth of the groove for fitting the O- rings 1 and 2 is set to be smaller than the diameter of the rubber cross section of the O- rings 1 and 2, thereby allowing the hollow fiber membrane module 5 to be watertight in the housing 6. It becomes possible to attach with.
また、図３に示される分割型のハウジングにあっては、中空糸膜モジュール挿入部７とは反対側に位置するハウジング端部９の内周表面および中空糸膜モジュール挿入部７側のハウジング端部８に対応する束着管外周表面にそれぞれシール部材嵌装用の溝が設けられる。この場合には、各端部に少なくとも２個のシール部材を装着することが容易となるので、全体では少なくとも４個のシール部材の装着を容易に行うことができる。この図の場合にも、Oリング１，２嵌装用の溝の深さは、Oリング１，２のゴム断面の直径よりも小さく設定され、これによって中空糸膜モジュール５をハウジング６に水密状態で装着させることが可能となる。
In the split housing shown in FIG. 3, the inner peripheral surface of the housing end 9 located on the opposite side of the hollow fiber membrane module insertion portion 7 and the housing end on the hollow fiber membrane module insertion portion 7 side are also provided. A groove for fitting a seal member is provided on the outer peripheral surface of the bundled tube corresponding to the portion 8. In this case, since it becomes easy to attach at least two seal members to each end, it is possible to easily attach at least four seal members as a whole. Also in the case of this figure, the depth of the groove for fitting the O- rings 1 and 2 is set smaller than the diameter of the rubber cross section of the O- rings 1 and 2, whereby the hollow fiber membrane module 5 is sealed in the housing 6. It becomes possible to attach with.
ハウジングがこれらいずれの場合にあっても、ハウジング内周表面あるいは束着管外周表面に位置するシール部材嵌装用の溝が設けられるハウジング端部とは、束着管を装着したときに、束着管側周部に設けられている空気あるいは流体の流出入孔が設けられている部分を除く束着管側端部と相対することとなる位置を指している。すなわち、この部位に生じているハウジング内周面と束着管外周面との間に生じる間隙をシール部材を用いて確実にシールすることで、中空糸を通過する前後の流体を完全に隔離することができる。
In any of these cases, the housing end provided with the groove for fitting the seal member located on the inner peripheral surface of the housing or the outer peripheral surface of the bundled tube is defined as the bundled tube when the bundled tube is mounted. It refers to the position facing the bundled tube side end excluding the portion provided with the air or fluid inflow / outflow holes provided in the tube side peripheral portion. That is, the gap generated between the inner peripheral surface of the housing and the outer peripheral surface of the bundled tube generated in this part is reliably sealed using a seal member, so that the fluid before and after passing through the hollow fiber is completely isolated. be able to.
