<p><P>PROBLEM TO BE SOLVED: To provide a technique of reducing noises and removing pollutants, such as nitrogen oxides, sulfur oxides, volatile hydrocarbons, and dust including suspended particulate matter, in a place, such as a roadside and an industrial area, situated in an environment with marked noise production and air pollution and being capable of ensuring a moderate ventilation quantity. <P>SOLUTION: Disclosed is a cleaning structure comprising an activated carbon fiber molding 3 constituted from an activated carbon fiber, processed in a pleated form, and having air permeability across the pleats, a surface plate 4 disposed on the side of the pleat surfaces of the activated carbon fiber molding 3, and a backing plate 1 having sound insulating performance and disposed on the side of pleat backs, wherein the surface plate 4 has vent holes 4a allowing ventilation across the surface plate 4, and a communicating space running along pleat folds and formed on the pleat valleys confined by the activated carbon fiber molding 3 processed in the pleated form functions as a cleaning space that cleans the fluid, as the object to be cleaned, entering from the vent holes 4a formed on the surface plate 4. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
