초록 ▼

A module is disclosed for use as a membrane device, comprising, a shell with fluid couplings removably affixed to each of its ends and at least one non-disassemblable cartridge operably held within the shell. The cartridge is constructed from plural wafers sequentially coaxially aligned, each wafer consisting essentially of a generally planar frame and an array of hollow fibers of selectively permeable material adhesively held by their ends in opposed portions of the border of the frame, without initially potting the ends. Each frame has a central through-passage, and multiple frames together define an axial through passage in each cartridge through which a feedstream is typically flowed in “outside-in”flow. Each opposed portion of border is provided with longitudinal, laterally spaced apart grooves in its upper surface and the fibers trained in the grooves, and successive wafers are bonded together. The bores of the fibers are in open fluid communication with the permeate zone in the shell. Arrays lie in a plane substantially orthogonal to the direction of flow of the feedstream, and fibers of one array are staggered relative to those in a successive array. The ends of the fibers are post-potted by filling a potting channel formed by elongated slots in opposed portions of the borders of successive frames, the ends of which successive slots are in open fluid communication. Several cartridges may be coaxially “ganged”or “stacked”to provide the required filtration area. The cartridges may be removably disposed in the shell, or secured therein so that the entire module may be discarded when its efficiency is unacceptably low.

In a cartridge to be inserted in a module for use in a membrane device, the improvement comprising, plural repeating units, each being a unitary wafer consisting essentially of (i) an array comprising a single monolayer of individual spaced apart hollow fibers of selectively perucable material secured near their terminal portions in near-fluid-tight relationship therewith, without being interconnected intermediate said terminal portions, each said array held non-displaceably by said terminal portions in (ii) a unitary laminar frame having a continuous periphery, a through-passage within said frame defining a perforate planar border having opposed elongated slots within opposed portions of said border, within which border said fibers are secured; (iii) a multiplicity of said unitary laminar frames assembled vertically, one in direct contact upon another, so that said opposed end portions of elongated slots in successive said laminar frames are in open fluid communication with one and another; and, (iv) an end unitary laminar frame secured in fluid-tight relationship with the last and uppermost array, whereby each array is sandwiched between an upper and a lower frame so that a predetermined number of arrays “n”have been sequentially secured in position, each in fluid-tight relationship with the preceding prior array, and capped by said end unitary laminar frame, so that the number of arrays held between successive frames is one less than the number of frames in which the fibers are held, where n represents an integer greater than 2.
