Abstract
The disclosure is directed to a method of dehumidification of air or gas which includes the steps of preparing a dehumidifying member composed of active carbon fiber material in the form of sheets, and bringing air or gas to be dehumidified into contact with the dehumidifying member in a direction parallel to the sheets for a less air passing resistance.
Claims21
A method of dehumidification which comprises the steps of preparing a dehumidifying member composed of active carbon fiber material, in the form of sheets and bringing air to be dehumidified into contact with said dehumidifying member for the dehumidification of air.
An air dehumidifying arrangement which comprises a pair of dehumidifying members axially aligned and rotatably provided in a spaced relation from each other, each of said dehumidifying members being formed by a moisture adsorbing element which is composed of a corrugated sheet of active carbon fibers and a flat separate sheet of active carbon fibers bonded to one surface of said corrugated sheet, and which is spirally wound to form said dehumidifying member, with air passage defined therebetween being arranged in substantially the same direction, and a heat exchanging member fixedly disposed coaxially between said dehumidifying members and having one portion which allows air to be dehumidified to pass therethrough and through which cooling medium is passed for cooling the air to be dehumidified, and another portion for permitting hot air for dehumidification and regeneration of the active carbon fibers to pass therethrough.
An air dehumidifying arrangement which comprises a rotatable hollow cylindrical dehumidifying member composed of moisture adsorbing elements each formed by a corrugated sheet of active carbon fibers and cooling air flow passing elements each formed by a corrugated sheet of non-moisture adsorbing material and a separate flat sheet of non-moisture adsorbing material applied to both surfaces of said corrugated sheet of non-moisture adsorbing material so as to define a large number of air passages therebetween, with said moisture adsorbing elements and cooling air flow passing elements being alternately laminated one upon another so that the respective air passages of said moisture adsorbing elements and said cooling air flow passing elements are alternately arranged to be directed in the axial direction and radial direction of said hollow cylindrical dehumidifying member so as to pass the air to be dehumidified through said moisture adsorbing elements and to pass cool air through said cooling air flow passing elements, and a regenerating means provided to surround one portion of said rotatable hollow cylindrical dehumidifying member for regenerating active carbon fibers of said moisture adsorbing elements by passing regeneration gas through said moisture adsorbing elements.
