Field of the Invention The present invention relates to a hollow fiber membrane filtration module used for filtration by a hollow fiber membrane whose temperature changes drastically, especially for high temperature sterilization or hot water filtration, or a filtration module having a large inner diameter of a module case, that is, a large size module. The present invention relates to a hollow fiber filtration module.

ース外径を大きくするには限界が存在した。However, since the liquid sealing resin for molding and the case material are different materials, the coefficient of thermal expansion between the materials is increased in filtration in a system where the temperature changes drastically. Subject to distortion due to the difference. This is because the larger the module is, the larger the size of the case is, the adhesive is peeled off due to heat cycle, the sealing resin is liable to crack, and the durability is insufficient. There wasn't. Further, as the liquid sealing resin used for modularization, only a resin having a very small curing shrinkage can be used. And, even if the encapsulation casting resin having extremely small curing shrinkage is used, there is a limit in increasing the outer diameter of the module case.

的としている。The present invention is intended to improve a seal structure having a good heat cycle property, and since it has excellent heat resistance and chemical resistance, but has a large curing shrinkage, it has not been conventionally used in a module having a large case outer diameter. It is possible to use a casting resin for stoppage, and it is an object of the present invention to provide a hollow fiber membrane module particularly suitable as a large module.

を見出し、本発明を完成させるに至ったものである。[Means for Solving the Problems] As a result of various studies to achieve this object, it was found that it is effective to form a groove having a predetermined angle in the depth direction on the inner wall surface of the case. The present invention has been completed.

中空糸膜モジュールにある。That is, the gist of the present invention is that a hollow fiber bundle consisting of a plurality of hollow fiber membranes is housed in a case, and the end portions on the opening side of each hollow fiber membrane are fixedly sealed with a casting resin at the end portions of the case. In the hollow fiber membrane module described above, a single or a plurality of grooves having a predetermined depth are formed continuously or intermittently on the inner wall surface of the end portion of the case, and the grooves are 3 with respect to the center line inside the case. The hollow fiber membrane module is characterized by being inclined at an angle of ° to 85 °.

ることが最も好ましい。However, in the present invention, it is necessary to incline the groove depth direction at a specific angle. That is, it is necessary to incline the angle with respect to the inner centerline of the case within the range of 3 ° to 85 °. If this angle is 3 ° or less, the sealing resin may be torn off at the entrance of the groove, and 85 °
As described above, resin peeling may still occur. Further, in the present invention, it is most preferable that the depth of the groove in the direction perpendicular to the center line is 0.5 to 30 mm and the groove width is 0.5 to 100 mm.

加させる。[Function] Since the casting resin for sealing the hollow fiber membrane is integrally formed in the groove by being bonded and integrated, the casting resin adheres to the inner surface of the case in a stepwise manner, and the bonding area increases only. Rather, the peeling direction is not constant, the substantial peeling resistance is increased, and it withstands heat cycle and high pressure in the case well. Moreover, by limiting the depth direction of the groove as described above, leakage from the interface of the case is surely eliminated, and at the same time, the pressure resistance of the casting resin against the liquid pressure in the case is further increased.
