Abstract
Description
本発明は、液体の濾過等に用いる中空糸膜モジュールの製造方法に関する。 The present invention relates to a method for producing a hollow fiber membrane module used for liquid filtration and the like.
中空糸膜モジュールは、従来から、無菌水、飲料水、高度純水の製造、空気の浄化等の数多くの用途で使用されてきた。これらの用途に加えて、近年では、下水処理場における２次処理、３次処理や、浄化槽における固液分離、産業廃水中のＳＳ（懸濁物質）の固液分離など、高汚濁性水の処理用途に用いられるようになっている。 The hollow fiber membrane module has been conventionally used in many applications such as aseptic water, drinking water, production of highly pure water, and air purification. In addition to these applications, in recent years, highly polluted water such as secondary and tertiary treatment in sewage treatment plants, solid-liquid separation in septic tanks, solid-liquid separation of SS (suspended material) in industrial wastewater, etc. It is used for processing purposes.
これらの高汚濁性水濾過の用途に使用可能な中空糸膜モジュールを効率良く製造する方法として、かせ枠体に中空糸膜を巻き付ける各種方法が開示されており、例えば、かせ枠体に中空糸膜を巻き付けて、接着剤によって固着し、場合によっては該かせ枠体と共に該中空糸膜の端部を切断して、該中空糸膜の開口端面を露出させた後、中空糸膜の前記開口端面が位置する領域に濾過液流路を設ける中空糸膜モジュールの製造方法が示されている（特許文献１）。 Various methods for winding a hollow fiber membrane around a skein frame body have been disclosed as a method for efficiently producing a hollow fiber membrane module that can be used for these highly polluting water filtration applications. The membrane is wound and fixed by an adhesive, and in some cases, the end of the hollow fiber membrane is cut together with the skein frame to expose the opening end face of the hollow fiber membrane, and then the opening of the hollow fiber membrane A manufacturing method of a hollow fiber membrane module in which a filtrate flow path is provided in a region where an end face is located is shown (Patent Document 1).
一方、中空糸膜モジュールのユニットの単位体積あたりの中空糸膜モジュールの集積率を高くでき、しかもエアバブリング等の影響によるハウジングのたわみが少なく、中空糸膜の絡まりを発生させることの無い中空糸膜モジュールが提案されている（特許文献２）。
しかしながら、前記のかせ枠体を使用する従来の中空糸膜モジュールの製造方法においては、１本のかせ枠体に中空糸膜を巻き付けた巻き付け体から、１体の中空糸膜束を得るものであり、中空糸膜束を効率良く得られるような中空糸膜モジュールの製造方法としての限界がある。 However, in the conventional method for producing a hollow fiber membrane module using the skein frame body, a single hollow fiber membrane bundle is obtained from a wound body in which the hollow fiber membrane is wound around one skein frame body. In addition, there is a limit as a method for manufacturing a hollow fiber membrane module that can efficiently obtain a hollow fiber membrane bundle.
又、前記従来のかせ枠体を使用する中空糸膜モジュールの製造方法によって得られた中空糸膜モジュールは、中空糸膜束間にかせ枠体が挟み込まれたままになっており、該かせ枠体により生ずる中空糸膜束間の空隙部分に夾雑物が堆積しやすく、特に１モジュール当たりの濾過流量を増加させる目的で中空糸膜の本数を増加させると、夾雑物の堆積が更に加速される傾向にあり、このために中空糸膜面が閉塞してしまい、汚泥中での長期にわたる中空糸膜モジュールの運転が困難になる。 In addition, the hollow fiber membrane module obtained by the method for producing a hollow fiber membrane module using the conventional skein frame body has the skein frame body sandwiched between the hollow fiber membrane bundles. Contaminants are likely to accumulate in the gaps between the hollow fiber membrane bundles produced by the body, and in particular, if the number of hollow fiber membranes is increased for the purpose of increasing the filtration flow rate per module, the accumulation of contaminants is further accelerated. This tends to block the hollow fiber membrane surface, making it difficult to operate the hollow fiber membrane module in sludge for a long time.
更に、前記従来のかせ枠体を使用する中空糸膜モジュールの製造方法によると、中空糸膜束間に不要な空隙の無い中空糸膜モジュール、つまりバブリング等の一般的な洗浄方法にて夾雑物の堆積を防止できる、例えば特開２００２−１７７７４４号公報における図面に示されるような中空糸膜モジュールを得ることは困難である。 Furthermore, according to the method for producing a hollow fiber membrane module using the conventional skein frame, a hollow fiber membrane module having no unnecessary voids between the hollow fiber membrane bundles, that is, a general cleaning method such as bubbling. For example, it is difficult to obtain a hollow fiber membrane module as shown in the drawing of JP-A-2002-177744.
従って本発明の目的は、中空糸膜束間に不要な空隙を有さない中空糸膜モジュールを、的確に、かつ能率良く得ることのできる中空糸膜モジュールの製造方法を提供することにある。 Accordingly, an object of the present invention is to provide a method for producing a hollow fiber membrane module capable of accurately and efficiently obtaining a hollow fiber membrane module having no unnecessary voids between the hollow fiber membrane bundles.

After the fixing cured resin layers (14 ′) and (16 ′) are formed, the inside of the partition plates (6) and (7) and the bent portions (11) and (12) of the hollow fiber membrane bundle (10) are formed. ) And the fixing cured resin layers (14 ′) and (16 ′) at the same time, and the remaining portions of the partition plates (6) and (7) are removed. Accordingly, the hollow fiber membrane bundle (10), preferably so that about 2 split.
以上の通り、本発明の中空糸膜モジュールの製造方法においては、複数本の中空糸膜（９）を固定用硬化樹脂層（１４’），（１６’）によって固定した状態で、該固定用硬化樹脂層（１４’），（１６’）の部分内を切断する手段を採るものであるから、中空糸膜束（１０）のばらつきが無く、取り扱い性が良好であると共に、仕切り板（６），（７）を固定用硬化樹脂層（１４’），（１６’）と同時に切断し、該仕切り板（６），（７）を取り除くことにより、１体のかせ枠体（１）に中空糸膜（９）を巻き付けた巻き状体から、２体の中空糸膜束（１９），（２０）を得るものであり、中空糸膜モジュールにするための中空糸膜束（１９），（２０）を極めて効率的良く製造することができる。 As described above, in the method for producing a hollow fiber membrane module of the present invention, a plurality of hollow fiber membranes (9) are fixed with the fixing cured resin layers (14 ′) and (16 ′). Since the means for cutting the inside of the cured resin layers (14 ′) and (16 ′) is taken, there is no variation in the hollow fiber membrane bundle (10), the handleability is good, and the partition plate (6 ) And (7) are cut simultaneously with the fixing cured resin layers (14 ′) and (16 ′), and the partition plates (6) and (7) are removed to form one skein frame (1). Two hollow fiber membrane bundles (19) and (20) are obtained from a wound body around which the hollow fiber membrane (9) is wound, and a hollow fiber membrane bundle (19) for forming a hollow fiber membrane module, (20) can be manufactured very efficiently.
更に、従来方法にて得られた中空糸膜モジュールは、中空糸膜束同士の間にかせ枠体が挟み込まれたままの構造であったために、モジュールに用いる中空糸膜の本数に限界があったが、本発明の製造方法によって得られる中空糸膜束（１９），（２０）には、中空糸膜束同士の間に挟み込まれたかせ枠体が無く、これによって用いる中空糸膜（９）の本数を大幅に増加させても、バブリング等の一般的な洗浄方法によって夾雑物の堆積を防止することが可能となる。なお、ここで用いる中空糸膜（９）の本数は、例えば単一の中空糸膜モジュール当たり１００〜１００００本の範囲が好ましく、５００〜５０００本の範囲がより好ましい。 Furthermore, since the hollow fiber membrane module obtained by the conventional method has a structure in which the skein frame is sandwiched between the hollow fiber membrane bundles, the number of hollow fiber membranes used in the module is limited. However, the hollow fiber membrane bundle (19), (20) obtained by the production method of the present invention does not have a skein frame sandwiched between the hollow fiber membrane bundles, and the hollow fiber membrane (9) used thereby. Even if the number of these is greatly increased, it is possible to prevent the accumulation of impurities by a general cleaning method such as bubbling.

A two-component curable urethane resin was injected and cured to form a fixing cured resin layer having a height of about 100 mm, and then the resin case was removed from the mold and removed.
（６）続いて、中空糸膜の端部を開口させるべく、高さ約１００ｍｍの二つの部分からなる固定用硬化樹脂層を、それぞれ約３０ｍｍの高さを残して、外端面から約７０ｍｍの位置を中空糸膜の長さ方向（Ｚ−Ｚ′）と直交する一方向（Ｘ−Ｘ′）の面で切断し、すなわちポリエチレン樹脂製の仕切り板の部分内で切断し、切断部分を取り除いた。なお、前記固定用硬化樹脂層の外端面から約７０ｍｍの位置で切断することによって、中空糸膜束の巻き曲がり部分を切断し、これを除去することによって、各中空糸膜束の両端部の固定用硬化樹脂層内に、中空糸膜の開口端面を露出させた。 (6) Subsequently, in order to open the end portion of the hollow fiber membrane, a fixing cured resin layer composed of two portions having a height of about 100 mm is left about 70 mm from the outer end surface, leaving a height of about 30 mm. The position is cut in one direction (XX ') perpendicular to the length direction (Z-Z') of the hollow fiber membrane, that is, cut in the part of the polyethylene resin partition plate, and the cut part is removed.
