Abstract
A hollow fiber module of a device for separating fluids has hollow fibers with walls that have partially permeable structures. The hollow fibers are positioned parallel to each other. At least one areal fluid-permeable spacer medium with a structure that is self-supporting an areal state of the at least one spacer medium is provided and arranged between the hollow fibers such that the at least one spacer medium surrounds at least partially circumferentially a first one of two neighboring hollow fibers at least on a side of the first hollow fiber that is facing the second one of the two neighboring hollow fibers.
Claims16
A hollow fiber module of a device for separating fluids, the module comprising:
- hollow fibers comprising walls that are comprised of partially permeable structures, the hollow fibers positioned parallel to each other;
- at least one areal fluid-permeable spacer medium comprising a structure that is self-supporting an areal state of the at least one spacer medium;
- the at least one spacer medium arranged between the hollow fibers such that the at least one spacer medium surrounds at least partially circumferentially a first one of two neighboring hollow fibers at least on a side of said first hollow fiber that is facing the second one of the two neighboring hollow fibers;
- wherein a first spacer medium of the at least one spacer medium is an air permeable mat of open, flexible material;
- wherein the mat is corrugated to form a continuous corrugated mat having a plurality of alternating corrugation valleys and corrugation peaks, the corrugation valleys opening at a first side of the corrugated mat and the corrugation peaks opening at an opposing second side of the corrugated mat;
- wherein a first portion of the hollow fibers are arranged directly on the corrugated mat in corrugation valleys opening at the first side of the corrugated mat;
- wherein a second portion of the hollow fibers are arranged directly on the corrugated mat in immediately adjacent corrugation peaks opening in the opposing second side of the corrugated mat, such that individual ones of the hollow fibers are arranged alternatingly in the corrugation valleys and corrugation peaks at opposite sides of the corrugated mat to form a hollow fiber layer.
A hollow fiber module of a device for separating fluids, the module comprising:
- hollow fibers comprising walls that are comprised of partially permeable structures, the hollow fibers positioned parallel to each other;
- at least one areal fluid-permeable spacer medium comprising a structure that is self-supporting an areal state of the at least one spacer medium;
- a plurality of spacer hoses of a woven textile material or a foam material, wherein the hollow fibers each are each arranged in a respective one of said plurality of spacer hoses, wherein said spacer hoses each comprise a fluid-permeable circumferential wall;
- wherein the hollow fibers are not fixed to each other;
- wherein contact of neighboring spacer hoses fixes spacing between neighboring hollow fibers;
- wherein the hollow fibers are separated from each other only by the spacer hoses and not by other separating elements or structures.
