<p>PROBLEM TO BE SOLVED: To efficiently remove hot harmful gaseous components discharged from a garbage incinerator, an automobile, etc., under a small pressure drop by fixing a deodorant having gas adsorbing performance and decomposing performance on a material having a three-dimensional network skeleton structure and imparting heat resistance and regenerating function. SOLUTION: An inorg. firing material is fired on the skeleton of a polyurethane form or a resin net having a three-dimensional network skeleton structure so as to improve the heat resistance of the structure. A cubic net based on synthetic chemical fibers of PP, etc., is suitable for use as the material having the three-dimensional network skeleton structure. A deodorant having gas adsorbing performance and decomposing performance is then fixed on the front, rear and lateral faces of the polyurethane foam or resin net and on the inner skeleton with an inorg. binder such as a colloidal silica type inorg. binder or water glass to produce the objective deodorization filter.</p> |
