<p><P>PROBLEM TO BE SOLVED: To provide a duct for a bagfilter capable of greatly lowering a material cost and a construction cost required for forming and installing a whole duct as compared with a conventional stepwise plenum system while preventing a pressure drop and a turbulent flow in an inlet duct even if increasing an inlet area of the inlet duct to increase a treatment amount of exhaust gas. <P>SOLUTION: The duct 10 for the bagfilter is installed to the bagfilter 30, 30 arranged in parallel, wherein the inlet duct 12 and the outlet duct 14 are formed by dividing a duct casing 11 with a partition wall 22. The partition wall 22 is arranged to be inclined so that a volume decreases according to a distance from a supplying opening 12b where an exhaust gas is supplied. Under the inlet duct 12, inlet branch ducts 16, 16 equipped with a flow straightening plate 20, 20 is arranged. The upper side between the respective inlet branch ducts 16, 16 is formed to be as inclined as the partition wall 22 located to be faced. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
