<p>PURPOSE:To improve deodorization and dust collection performances by parallelly disposing laminated adsorptive bodies, consisting of a first member with a plurality of protrusions and a flat-plate-like second member, and dust- collecting venting sheets in a flow direction of fluids to be treated to form a filter. CONSTITUTION:One of a first member with a plurality of protrusions and a flat-plate-like second member is formed out of electret non-woven fabrics, while the other thereof is formed out of paper containing carbon fiber having paper structure, whereby both the members are superposed on one another to provide a laminated adsorptive body A. In concrete terms, the first member 1 consisting of paper containing active carbon fibers of paper structure, having protrusions 2 thereon, and the flat-plate-like second member 3 are superposed on one another to form a laminated adsorptive body A in such a way that the protrusions overlap each other in the direction of superposition. Sheets 5 for dust collection and air flow are provided in a casing 4, while the adsorptive bodies A are stacked to form a multistage laminated construction on the downstream side of the flow of fluids to be treated, whereby a filter is provided.</p> |
