PROBLEM TO BE SOLVED: To realize a chlorine bypass equipment or the like comprising a multi-gas extraction part/single treatment system by using a gas converging device capable of easily setting a distribution ratio of gas amount and preventing an imbalance of gas temperature at the gas treatment part. SOLUTION: In a gas converging device 15 equipped with a plurality of gas inlet ducts 16 introducing an extracted gas from a cement manufacturing process, a chamber 17, and a gas outlet duct 18 whose number is less than that of the gas inlet ducts 16, the gas inlet ducts 16 and the gas outlet duct 18 are connected with a distance each other to the chamber 17. The distance between the gas inlet duct 16 and the gas outlet duct 18 is set at an extent over 2.5 times of the inner diameter of the gas inlet ducts 16. A flow control damper 19 is installed at least at one of a plurality of the gas inlet ducts 16. A dust recovery duct 30 to discharge dust precipitated in the chamber 17 and a cooling air duct 40 to introduce the cooling air to the chamber 17 can be installed. COPYRIGHT: (C)2006,JPO&NCIPI
