<P>PROBLEM TO BE SOLVED: To reduce labor for mounting a sheet-like filter when the sheet-like filter is mounted so as to divide an exhaust gas passage. <P>SOLUTION: This device is the dioxins removal device in which the exhaust gas passage is divided to front and rear spaces A1, A2 in the exhaust gas passing direction by the sheet-like filter 2 shape-retained by a shape-retaining frame 9 and the dioxins in the exhaust gas passing through the exhaust gas passage can be adsorbed to the sheet-like filter. The shape-retaining frame is formed to a cylindrical shape with a bottom having a large number of ventilation ports 11 formed at an intermediate part in a cylinder shaft direction and an opening side peripheral part is sealingly connected to an inner side relative to a passage forming member of the exhaust gas passage. The sheet-like filter is covered on the shape-retaining frame so as to cover the ventilation port by connecting a pair of side parts opposed to each other. Thereby, the shape is retained to the cylindrical shape and both ends are sealingly fixed to an outer peripheral part of the shape-retaining frame by an end fixing member 22. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
