| 摘要 |
A hollow fibre membrane module with a fixed structure comprises: a bearing shell (7), an inlet (8), a concentrated water outlet (10), a produced water outlet (9), a central tube (1) and hollow fibre membranes (6), in which the hollow fibre membranes (6), the central tube (1) and the bearing shell (7) are fixed together, the inlet (8) is located at one end of the hollow fibre membranes (6), the concentrated water outlet (10) is located at the other end of the hollow fibre membranes (6), the produced water outlet(s) (9) is(are) located at one end or both ends of the central tube (1), and there are small holes drilled on the side wall of the central tube (1). The module also comprises at least one separate fixed ring(s)(2) for fixing the hollow fibre membranes (6), with the separate fixed ring(s)(2) fixed on the central tube (1) and the hollow fibre membranes (6) arranged in parallel through the separate fixed ring(s)(2).
