no. 1 Embodiment approach

[0052] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0053] figure 1 It is a perspective view of a flat hollow fiber membrane module according to an embodiment of the present invention. figure 2 is along figure 1 The cross-sectional view of the flat hollow fiber membrane module of line II-II. image 3 It is an exploded cross-sectional view of the casing for the flat hollow fiber membrane module. In the description below, the figure 2 , 3 The upper part is called the upper part, and the lower part is called the lower part.

[0054] like figure 1 As shown, the flat hollow fiber membrane module 10 of this embodiment includes: a hollow fiber membrane sheet-like assembly 12 formed of a plurality of hollow fiber membranes 11, and a second hollow fiber membrane sheet-like assembly 12 inserted into the end. A housing 1 and a second housing 13 .

[0055] The hollow fiber membrane sheet-like assembly 12 is a str...

no. 2 Embodiment approach

[0087] Next, a second embodiment of the flat hollow fiber membrane module of the present invention will be described. Figure 4 It is a cross-sectional view of a flat-type hollow fiber membrane module according to a second embodiment of the present invention. In addition, in this embodiment, the difference from the above-mentioned embodiment will be mainly described, and the description of the same part will be omitted.

[0088] from Figure 4 It can be seen that in the flat hollow fiber membrane module of the second embodiment, the shapes of the fitting portions of the connecting member 4A, the housing body 2A, and the cover portion 3A, that is, the shapes of the fitting portions of the flange guide portion 23 and the guide portion 34 are respectively It is a dovetail shape that gradually expands. The dovetail groove shape means that the cross section of the groove is trapezoidal, and the width of the bottom surface of the groove is larger than the width of the top surface ...

no. 3 Embodiment approach

[0093] Next, a third embodiment of the flat hollow fiber membrane module of the present invention will be described. In addition, in this embodiment, the difference from the above-mentioned embodiment will be mainly described, and the description of the same part will be omitted.

[0094] The first housing 1B of the flat hollow fiber membrane module of the third embodiment is the same as that of the first embodiment and the second embodiment in that the opening 7 of the housing main body 2B is openably and closably closed by the cover 3B. , but the connection method between the cover portion 3B and the case main body 2B is different.

[0095] like Figure 5 As shown, among the outer walls 24B of the housing main body 2B, the outer wall 24Ba along the longitudinal direction of the first housing 1B is provided with a flange portion 23B protruding from the outer wall 24Ba. On the lower surface of the flange portion 23B, a groove 40 is formed along the length direction of the firs...

Abstract

The invention relates to a hollow fiber membrane module. The shell constituting the hollow fiber membrane module includes: a shell main body (2) and a cover part (3). The shell main body (2) has an insertion port (21), the insertion port (21 ) is inserted into the ends of the plurality of hollow fiber membranes (11) and fixedly holds the ends of the plurality of hollow fiber membranes (11); 21) Open end faces of the inserted plurality of hollow fiber membranes (11) are exposed to the outside, and the cover portion (3) closes the opening portion (7) of the case main body (2). According to the present invention, there is provided a case capable of easily exposing the opening end surface of the hollow fiber membrane and sealing the opening end surface of the hollow fiber membrane when the hollow fiber membrane is damaged.

Description

technical field [0001] The present invention relates to a hollow fiber membrane module used in solid-liquid separation operations such as water treatment. [0002] This application claims priority based on Japanese Patent Application No. 2011-000153 for which it applied in Japan on January 4, 2011, and uses the content here. Background technique [0003] Hollow fiber membrane modules are used as filter materials in many applications such as the production of sterile water, drinking water, highly pure water, and air purification. As hollow fiber membrane modules, hollow fiber membranes are produced in bundle form, hollow fiber membranes are produced in sheet form and laminated, etc., and are produced in various forms (see Patent Document 1). [0004] A hollow fiber membrane module in which hollow fiber membranes are stacked is also called a flat hollow fiber membrane module, and a plurality of stacked hollow fiber membranes are fixed by a casing (see Patent Document 2). Ins...
