ABSTRACT:
Fluid fractionating apparatus and a unit for use therein, the unit being positionable in a jacket having at least one fluid inlet and at least one fluid outlet, the unit including at least one leakproof band wound up in the form of a spiral cylinder, the turns of which are radially spaced from one another. A multiplicity of hollow fibres are wound around the turns of the spiral cylinder and extend therebetween. Two end walls extend perpendicular to the axis of the spiral cylinder, and may be formed of a solidified glue, the walls being located one at each end of the cylinder and firmly fixed to the leakproof band of the hollow fibres, at least some of the fibres crossing right through at least one of the end walls and opening on the side thereof outside the spiral cylinder. An opening, which may be provided with a hollow mandrel extending into the interior of the innermost turn of the spiral, is used for feeding the fluid thereto or removing it therefrom.
The unit element may be formed by winding a plurality of hollow fibres around a leakproof band, coiling the leakproof band together with the hollow fibres into a cylindrical spiral, gluing the ends of the spiral cylinder thus produced and cutting the ends of the hollow fibres.
