no. 1 Embodiment approach ）

[0055] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0056] 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 on 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.

[0057] Such as 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 .

[0058] The hollow fiber membrane sheet-like assembly 12 is a ...

[0090] 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.

[0091] 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 ...

[0096]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.

[0097] 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.

[0098] Such as 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 ...

Abstract

The present invention relates to a hollow fiber membrane module comprising a housing which is provided with: an insertion slot (21) in which the end sections of a plurality of hollow fiber membranes (11) are inserted and securely held; a housing main body (2) which includes an opening (7) for exposing open end surfaces of the plurality of hollow fiber membranes (11) inserted in the insertion slot (21); and a cover section (3) for sealing the opening (7) of the housing main body (2). According to the present invention, a housing can be provided which makes it possible for the open end surfaces of the hollow fiber membranes to be easily exposed and for the open end surfaces of the hollow fiber membranes to be sealed when the hollow fiber membranes are 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 a bundle form, hollow fiber membranes are produced in a sheet form and laminated, etc., and are produced in various forms (see Patent Document 1). [0004] A hollow fiber membrane module in the form of stacked hollow fiber membranes 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)...
