2. Description of the Related Art Generally, a hollow fiber type membrane module has a large filtration membrane area within a fixed volume and can be downsized, so that it is used for various membrane separation applications. The hollow fiber type membrane module is usually a hollow fiber membrane bundle composed of a plurality of hollow fiber membranes, which is sealed by sealing resin between the hollow fiber membranes and the case housing, and at least one end surface of the hollow fiber membranes. Is configured in an open state. For these hollow fiber type membrane modules, two or more hollow fiber type membrane modules are connected in parallel for applications requiring a large amount of treatment, so as to have a large filtration membrane area. Alternatively, this is dealt with by simply enlarging one hollow fiber type membrane module.
In addition, a cartridge in which a hollow fiber membrane bundle is protected by a flow path material such as a plastic net, and both ends of the hollow fiber membrane bundle are adhesively sealed together with the flow path material are housed in a case housing.
A large module such as a tridge type hollow fiber type membrane is known.

However, the cartridge type large hollow fiber type membrane module has the following problems. That is, these hollow fiber type membrane large modules
However, for convenience of handling, the maximum diameter is 1
Collect the hollow fiber membrane bundles of about 5 cm as one unit,
A plurality of these hollow fiber membrane bundles are housed and used in a cylindrical case housing. In this case, a plurality of the cylindrical hollow fiber membrane bundles assembled inevitably form a gap between the cylinders in the case housing. When the hollow fiber membrane is washed or sterilized, this gap or space becomes a dead space which requires a long time to completely fill the module or the like with the drug or conversely to completely remove the drug. In order to solve such a problem, for example, Japanese Patent Laid-Open No. 62-1409 proposes a large hollow fiber type membrane module in which a case housing is deformed. However, such a case housing is complicated to manufacture and use, and the cost is high. Further, a polygonal module or a cartridge element has been proposed as in JP-A-62-163709 or JP-A-2-6825, but these also have a complicated module structure, Since the pressure resistant structure becomes difficult, the cost becomes high. Therefore, an object of the present invention is to provide a hollow fiber type membrane module which can be easily formed and which eliminates a wasteful space in the cylindrical case housing.

Comparative Example 1 Hollow fiber membrane 3 similar to that of Example 1
A hollow fiber membrane bundle of 460 filaments was used in Example 1 and Example 2.
Using a mesh net made of the same material as the protective cylinder used in Example 1, the net was housed in a cylindrical protective cylinder having an inner diameter of 10.5 cm and an outer diameter of 11.3 cm, and in the same manner as in Example 1, seven cylindrical cartridges were used. (Cylindrical unit filtration element) was obtained. These were housed in the same case housing as in Example 1 and sealed in the same manner to obtain a hollow fiber type membrane module (FIGS. 6 and 7). The membrane area of the obtained large module of hollow fiber type membrane was 58 m 2 in terms of hollow fiber inner diameter. Further, when the volume of the space outside the hollow fiber membrane in the case housing was measured in the same manner as in Example 1, it was about 55 liters. The filling rate of the hollow fiber membrane bundle in the protective cylinder was 53%.

(Results) From Example 1 and Comparative Example 1, even if the same case housing was used, the cylindrical cartridge (fan-shaped unit filtration element) was used. Since the membrane area of the hollow fiber membrane is larger than that of the cylindrical unit filtration element) and the volume of the space is small, the volume efficiency was excellent. Further, in the large hollow fiber type membrane module of Example 1 having the same membrane area as that of Comparative Example 1, the same effect could be exhibited even if the case housing used was smaller.

INDUSTRIAL APPLICABILITY According to the present invention, a large hollow fiber type membrane module for the purpose of mass processing can be easily constructed by using a plurality of fan type unit filtration elements. Moreover, in this case, since the plurality of fan-shaped unit filtration elements form a columnar shape, the volume of the space portion in the case housing can be reduced, and the membrane area of the hollow fiber membrane per case housing can be increased. be able to.
