<P>PROBLEM TO BE SOLVED: To eliminate influence caused by a level difference at the winding end part of a metal carrier to improve the performance of the metal carrier as a clarification device. <P>SOLUTION: A metal carrier built-in clarification device is provide with; a metal carrier 1 having honeycomb-like structure which is formed by alternately overlapping strips of corrugated foils 1a and flat foils 1b and connecting these foils with each other as they remain wound up in a roll and keeps a catalyst adhering to the surface after the connection; a cylindrical metallic container which keeps the metal carrier inserted and a metal carrier housing machined at both its axial ends, after the insertion, to have a reduced diameter as a tapered diffuser to hold the metal carrier; and a cushioning member 23 which is inserted into the inner part of the container together with the metal carrier as it remains wound around the outer periphery of the metal carrier, to be put between the inner circumference of the container and the outer periphery of the metal carrier. The cushioning member is formed to have a different-section shape which absorbs a radial level difference H at the wound-up end parts of the corrugated foils and flat foils which constitute the metal carrier. <P>COPYRIGHT: (C)2007,JPO&INPIT |
