関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hollow fiber type module in which the ends of a hollow fiber membrane bundle are fixed in two layers in the longitudinal direction of the bundle with different materials.

Typical membrane separation modules are known as flat membrane type, tubular type, and hollow fiber type. Hollow fiber type modules have a large membrane area per unit volume, and separate the raw solution and permeated liquid to be processed through the membrane. It has various advantages such as a simple sealing mechanism. Conventionally, such hollow fiber modules are made by bundling multiple hollow fiber membranes and then loading them into a case.
It is manufactured by injecting and filling a sealant to fix the hollow fiber membranes to each other and airtightly seal the edges of the case.
The sealant for fixing is required to have a high degree of pressure resistance and durability, so a sealant with relatively high hardness is usually used.

液を中空糸の内側に通して使用した場合、シール
剤と中空糸膜との界面で応力集中が起り、中空糸
膜が破損するという問題があつた。 However, when the module manufactured in this way is used by passing the stock solution inside the hollow fiber under a combination of relatively high temperature and pressure conditions, stress concentration occurs at the interface between the sealant and the hollow fiber membrane, causing the hollow fiber to collapse. There was a problem that the thread membrane was damaged.

難点があつた。 In other words, when internal pressure is applied to the module at high temperature,
A force acts to inflate the hollow fiber membrane in the circumferential direction, but while the part that is fixed with a relatively hard sealant does not deform at all, the hollow fiber membrane part expands due to the magnitude of the stress. Therefore, since it deforms freely,
A sudden difference in the amount of deformation occurs at the interface, and the hollow fiber membrane cracks along its length starting from this point, and the hollow fiber membrane is used under conditions that effectively take advantage of its inherent pressure resistance. The problem was that I couldn't do it.

内側からの圧力に対するモジユールの耐圧性を向
上させることはできない。 As a method for reinforcing the bonded end, there is, for example, the method disclosed in Japanese Patent Application Laid-open No. 59-4403. This method prevents SS components from accumulating on the outer surface of the hollow fibers and damaging the hollow fibers. Specifically, the hollow fibers are coated and reinforced by coating and impregnating the surface of the hollow fibers near the bonded end with a resin, which prevents breakage of the hollow fibers on the outer periphery of the bundle due to bending moments at the bonded end. Although it is possible to prevent the membrane from becoming brittle due to the heat generated when bonding the ends, this method cannot improve the pressure resistance of the module against pressure from inside the hollow fiber.

The present application provides a hollow fiber type module that has pressure resistance against pressure from inside the hollow fiber membrane.

ものである。[Means for Solving the Problems] The present invention solves the above-mentioned problems by fixing the outermost end of the hollow fiber membrane bundle with a sealant that substantially adheres to the hollow fiber membranes, and A hollow fiber type characterized in that a layer formed of an elastic material that does not substantially adhere to the hollow fiber membranes is provided at the end of the hollow fiber membrane bundle that has become the sealing portion, in contact with the sealing portion. It is modular. That is, by providing a sealant layer and a layer made of an elastic material that does not substantially adhere to the hollow fiber membrane in contact with the sealant layer in the longitudinal direction of the hollow fiber membrane, the interface between the sealant and the hollow fiber membrane is This alleviates the difference in stress that occurs and improves pressure resistance.

Things can be given. A known method is employed to seal the hollow fiber membrane with a sealant.

てんし、形成される。 In order to alleviate the difference in stress occurring at the interface between the sealant and the hollow fiber membrane, the elastic body must be one that does not substantially adhere to the hollow fiber membrane. Examples of such elastic bodies include silicone, urethane, and other rubber-like substances. The elastic layer is provided in the longitudinal direction of the hollow fiber in contact with the end surface of the sealant layer to a thickness of 5 to 50 mm, preferably 5 to 10 mm. The elastic material layer is made by adjusting the viscosity of a liquid elastic material by adding a reactive diluent or solvent as necessary, and then applying head pressure or other known methods to contact the sealant layer. So it is filled and formed.
