MODULE MADE OF AT LEAST TWO-TYPE HOLLOW FIBRES, AND PRODUCTION OF SAME

摘要

The present invention relates to a membrane-fitted module and its process of manufacture, said module containing at least two groups of hollow fibers (8, 9), arranged in layers and loaded separately. The membrane-fitted module presents a housing shell comprising a groove-like central part (1) open on the upper side of the module as well as adjacent terminating elements (2, 3), which are also open on their upper side, each having as many arms (4, 5, 6, 7) as there are groups. In the housing shell are inserted groups of hollow fibres (8, 9) in stacked layers, arranged in the longitudinal direction of the central part (I). The ends of the membrane comprised of different groups of hollow fibers are placed in different arms (4, 5, 6, 7) of said terminating elements and embedded in a sealing material (10, 11) so as to leave open at least one end of the hollow-fibre membrane. Both the central part (1) of the housing shell and the terminating elements (2, 3) are tightly closed using a covering device (27, 36) which features around the hollow-fibre membranes an outer cavity (17) also filled with a fluid.
