Title:
【発明の名称】高表面積悪臭除去フィルタのための固形粒子を備えた芯ファイバ
Document Type and Number:
Japanese Patent JP2001520108
Kind Code:
A
Abstract:
A unique filtration device (10) which continuously removes gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a fine solid powder and a selected chemisorptive liquid (18) which can capture the gas phase contaminants. The wicking fibers (20) are generally disposed to extend in the same direction and are formed into a filter element (12). The air stream to be cleaned is directed through filter element (12). The wicking fibers (20) include internal longitudinal cavities (22) filled with a fine powder and each having a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected contaminant removing chemisorptive liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected chemisorptive liquid, with which they come into contact, through the internal cavities (22). The chemisorptive liquid and fine powder remains within the wicking fiber cavities (22) and generally does not enter the space between the wicking fibers yet through the longitudinal openings (24) the chemisorptive liquid is in full fluid communication with the air stream flowing past the fibers (20).
