Embodiment 1

[0051] Such as figure 2 As shown, the hollow fiber membrane element of this embodiment is composed of a pressure-bearing housing 7 , a water distribution pipe 5 , a hollow fiber membrane 6 , and a head cover 3 .

[0052] Wherein, the pressure-bearing shell 7 is a cylindrical structure with one end closed of plastic material, and is made of a plastic pipe with an outer diameter of 225mm, an inner diameter of 215mm, and a length of 1.5m. The packaging cover 3 is hermetically arranged at the other end of the pressure-bearing housing 7 , and there is a cap cavity 10 in the middle of the package cover 3 , and the cap cavity 10 is provided with a cap liquid port 2 . The cover cavity 10 is isolated from the inside of the pressure-bearing type shell 7 . The water distribution pipe 5 is arranged inside the pressure-bearing housing 7 through the packaging cover 3; regularly distributed water distribution holes 9 are arranged on the water distribution pipe 5. The part of the water dis...

Abstract

A hollow fibrous membrane element comprises a pressure-bearing housing (7), and hollow fibrous membranes (6), and a water distributing pipe (5). A head sealing cover (3) is disposed at one end of the pressure-bearing housing (7). The head sealing cover (3) is used for fixing the water distributing pipe (5) and sealing the pressure-bearing housing (7). A housing liquid port (8) is disposed in the pressure-bearing housing (7). A cover head liquid port (2) is disposed in the head sealing cover (3). One end of each hollow fibrous membrane (6) is fixed with the pressure-bearing housing (7). The interior of the hollow fibrous membrane (6) communicates with the cover head liquid port (2). The other end of each hollow fibrous membrane (6) is sealed. Each hollow fibrous membrane (6) is radially distributed in the pressure-bearing housing (7).

Description

technical field [0001] The invention relates to a membrane element, especially a hollow fiber membrane element, which is mainly used in the field of water treatment equipment. Background technique [0002] Existing hollow fiber membrane elements, no matter they are external pressure type, negative pressure pumping or internal pressure type, adopt the method of sealing both ends of the hollow fiber membrane, that is, use glue to fix both ends of the hollow fiber membrane to the two ends of the shell. [0003] For example, the utility model patent with the publication number CN201470318U provides a column-type hollow fiber membrane module with a stepped end structure, including a pressure-bearing shell, and the outer two ends of the pressure-bearing shell are provided with ends. Connect the end cover; the inside of the pressure-bearing shell is provided with a hollow fiber membrane, and the two sides of the hollow fiber membrane are respectively provided with a sealant. On th...
