<p>PURPOSE:To obtain an adsorption unit for an air cleaner having small pressure drop and long adsorption lifetime, by rolling and laminating an adsorption sheet with described space from each other and both ends thereof opened to the outside. CONSTITUTION:Agents to eliminate smell is applied to a sheet-like matter (e.g. non-woven fabrics of nylon) by impregnation or spraying to form an adsorption sheet 1. The adsorption sheet 1 thus obtained is formed into a laminated rolling structure having a space between adjacent sheets by, for example, inserting spacers thereinto, with both ends opened to the outside and is then molded into an adsorption unit, after which the adsorption unit 1 is placed and fixed in a case 2 in such a way that the surfaces thereof is parallel to the air flow. Air is sucked, as shown by an arrow A, into an end opening formed in the manner as stated above and flows parallel to the surface of the adsorption unit 1 to be discharged from the opposite opening as shown by an arrow B. As a result, since air does not cross the adsorption sheet 1, pressure drop of air is negligible. With regard to the adsorption unit, the ratio between the length L between both ends thereof and a space D provided between adjacent sheets is preferred to be L/D >=2.</p> |
