초록 ▼

A filter device and technique are described which rely on absorption rather than adsorption for the removal of gas phase contaminants. A filter media is composed of a plurality of wicking fibers each of which comprising a strand with a hollow region impregnated with any of a variety of liquid phase absorbing systems made from the combination of a carrier liquid and soluble complexing/degrading agent or agents. Each strand has a slot which connects the interior hollow region with an external surface. Capillary forces act on the carrier liquid such that the external surface is substantially dry and no appreciable adsorption of contaminates occurs on the external surface which would restrict the flow of an air stream through the filter media even after an extended period of use. The wicking fibers may be connected to an external reservoir which can be used to supply fresh absorbing fluid to the filter media giving them a potentially inexhaustible capacity. The filter media may be made from any of a variety of fibers which can rapidly transport a liquid phase by the nature of either their geometry or their chemical composition. Geometries may include multilobal cross-sectional configurations, porous hollow fibers, porous or striated fibers or tightly bundled microfibers, all of which exhibit the property of wicking fluid from an external source.

[ What is claimed is:] [8.] A cabin air filtration system for removing unwanted gases comprising:a cavity;a liquid reservoir;a gas absorbing liquid within the reservoir;an air flow path through the cavity;an internally wicking fibrous material having a plurality of elongated strands which are aligned to define a mesh within the cavity, said strands each having a hollow internal region extending longitudinally along said strand connected to an outer surface through at least one radial opening extending longitudinally along said strand, said hollow internal region transferring said gas absorbing liquid along a path transverse to the air flow path within the cavity to move liquid from the reservoir into the air flow path without significantly restricting the air flow path as unwanted gases are absorbed by said gas absorbing liquid after passing through said radial openings; andmeans for circulating air from a cabin through the mesh in the cavity along the air flow path and back into the cabin.
