本発明は、浄水器用の中空糸濾過モジユールに
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hollow fiber filtration module for a water purifier.
中空糸濾過膜は、優れた濾過機能を有している
ため、従来より高純度の工業用水、飲料水、医療
用の無菌水等を製造するための浄水器に使用され
てきた。
Since hollow fiber filtration membranes have excellent filtration functions, they have traditionally been used in water purifiers for producing highly purified industrial water, drinking water, sterile water for medical use, and the like.
これら浄水器に使用される中空糸濾過膜を具備
する濾過モジユールの構造としては、従来殆どの

いは一端を封鎖した糸状の形でそれぞれの開口端

た。 Conventionally, most of the structures of filtration modules equipped with hollow fiber filtration membranes used in water purifiers include hollow fiber filtration membranes in a cylindrical body in a U-shape or in the form of a thread with one end closed. It had a structure in which the opening end of the opening was fixed to a fixing member made of polyurethane or the like while keeping it open.
中空糸濾過モジユールを使用して、大量の用水
を工業的規模で処理するには、中空糸濾過膜の本
数を増加させるかあるいは中空糸濾過膜の長さを
長くすることで対処されてきた。 In order to treat large amounts of water on an industrial scale using hollow fiber filtration modules, measures have been taken by increasing the number of hollow fiber filtration membranes or by increasing the length of the hollow fiber filtration membranes.
しかし、単位面積当りの中空糸濾過膜の本数を

かつた。 However, if the number of hollow fiber filtration membranes per unit area is increased, the amount of water to be treated will increase in proportion to the number of installed hollow fiber filtration membranes to a certain extent, but if the installation density of hollow fiber filtration membranes becomes too high, the hollow fiber filtration Since the passage resistance of water for treatment to the center of the membrane bundle increases, it becomes impossible to increase the amount of water for treatment in proportion to the number of installed membranes. On the other hand, if the length of the hollow fiber filtration membrane is increased, the membrane area increases and the amount of water to be treated can be increased. If the length exceeds a certain length, the flow path resistance inside the hollow fiber filtration membrane becomes rate-determining, and the amount of water to be treated cannot be increased.
しかしながら、時によつては、大量の用水をで

濾過モジユールでは対処できなかつた。 However, sometimes it is required to treat a large amount of water using a hollow fiber filtration module that is as compact as possible, and in such cases, a hollow fiber filtration module with a conventionally known structure is I couldn't deal with it.

In order to solve the problems of the conventional hollow fiber filtration module described above, the present inventors have provided a filtrate collection chamber at one end of the module, and the filtrate in this filtrate collection chamber is combined with the filtrate collected at the other end. A hollow fiber filtration module with a completely new structure equipped with filtrate piping for merging was proposed in Japanese Patent Application No. 59-100571 and No. 59-100572.

てしまうことがあり、その傾向はモジユールが大
型化する程顕著となつた。 These hollow fiber filtration modules were not intended to treat large amounts of water with a module that was as compact as possible. However, in order to simplify the structure of the module, if the filtrate piping is placed in the center of a fixed member made of a resin such as polyurethane that is fixed to the inner surface of the annular member at both ends of the module, it is possible to Alternatively, the vibrations and stress applied to the module during use are concentrated at the joint between the filtrate piping and the fixing member, which tends to cause peeling at this joint, making it impossible for the fixing member to fulfill its role as a partition member. In extreme cases, the module may be destroyed, and this tendency becomes more pronounced as the module becomes larger.

に対してかなりの防止効果が認められる。 In the filtration module of the present invention, the supporting member 4 having rigidity for fixing the arrangement position of the filtrate pipe 7 within the fixing member 2 is connected to the annular members 1, 1'.
It is attached to be connected to. 2a and 2b are a plan view and a cross-sectional view taken along the line A-A showing an example of an embodiment of the support member 4, which includes the filtrate pipe 7 and the joints 8, 9 with the annular members 1, 1'. At the same time, it has a cavity 10 that allows the hollow fiber filtration membrane 3 to be placed therein. The number of voids 10 may be any number as long as they are plural, but due to the processing of the material,
Approximately 3 to 5 pieces are preferable. The joint portion 9 has a cylindrical shape with a sufficient length 1 to function to fix the installation position of the filtrate pipe 7 and at the same time to prevent stress transmitted from the filtrate pipe 7 from being applied to the fixing member 2 as much as possible. It is preferable that As mentioned above, the purpose of installing the support member 4 is to reduce the stress applied to the fixing member 2 through the filtrate pipe 7, so it is appropriate that the support member 4 is made of hard resin or metal. be. It is preferable that the support member 4 is disposed in both of the two hollow fiber membrane fixing parts, but even if it is disposed only in the annular member 1 on the side that does not have the filtrate collecting chamber 5, the support member 4 and the filtrate piping are A considerable effect of preventing peeling with No. 7 was observed.

させることができる。 In the hollow fiber filtration module of the present invention, by installing the filtrate piping 7 that connects the hollow fiber membrane fixing part, the water collection port for the filtrate per module is located at one part of the water collection surface on the side where the filtrate collection chamber 5 is not provided. The installation and fixing part of the hollow fiber filtration module in a hollow fiber filtration module unit incorporating a large number of hollow fiber filtration modules can be halved. Furthermore, in the case of hollow fiber filtration membranes, generally, due to the relationship between the inner diameter of the hollow fiber filtration membrane and the permeation performance of the filtration membrane,
The longer the length, the more the hollow fiber filtration membrane is unable to exhibit its inherent permeability. That is, in a normal flat membrane, if the area of the permeable membrane is doubled, for example, the amount of permeation will be doubled under the same operating conditions. However, in the case of hollow fiber membranes, for example, even if the membrane area doubles, the amount of permeation does not double, but decreases, although this varies depending on the relationship between its form (inner diameter) and permeation performance. The degree of this decrease increases as the length increases. In the example module shown in Figure 1, the water collection surfaces are at both ends of the module, and the filtrate that has filtered through the hollow fiber membrane is collected from the water collection ports at both ends, thereby effectively cutting the length of the hollow fiber membrane in half. It has the effect of
The amount of permeation per unit membrane area can be increased accordingly. In addition, as in the example shown in Figure 3, by dividing the module into two with the same unit length and arranging the U-shaped hollow fiber filtration membranes to face each other, the pressure loss of the hollow fiber filtration membranes can be reduced. The length that contributes to this is halved, and the amount of permeation per unit membrane area can be increased by that much.
