<p><P>PROBLEM TO BE SOLVED: To provide an improved hollow fiber separation membrane module constituted so as to more enhance the pressure-resistant capacity and durability of a tube plate. <P>SOLUTION: In this hollow fiber separation membrane module wherein a pressure receving surface and a falling-off preventing surface are provided to a part where the tube plate and a container are in contact with each other, (1) the pressure receiving surface is vertical to the pressure direction applied to the tube plate when used and provided so as to be separated by 15 mm or above from the surface of the tube plate receiving pressure when used, (2) the corner parts of the pressure receiving surface are chamfered and (3) the falling-off preventing surface is provided between the surface of the tube plate receiving pressure when used and inclined by 90-150°with respect to the surface between the falling-off preventing surface and the pressure receiving surface or provided behind the pressure receiving surface when looked from the pressure direction applied to the tube plate when used. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
