CHLORINE BYPASS DEVICE
The present invention provides a chlorine bypass device which can cool exhaust gas quickly by mixing extracted exhaust gas with cooling air at high efficiency, thereby produce fine chloride dust, and increase dust recovery efficiency. In the present invention, a cooling pipe 21 adapted to cause cooling air to flow into an extraction pipe 20 adapted to extract part of exhaust gas from an exhaust gas pipe is formed by an annular revolving portion 22 and an introducing portion 23, the revolving portion 22 includes an inner pipe 24 and outer pipe 25 configured to be cylindrical in shape and adapted to surround an outer wall of the extraction pipe via a gap, the introducing portion 23 is defined by a reduced-diameter pipe 28 joined at a first end to the outer pipe of the revolving portion 22 and joined at a second end to the outer wall of the extraction pipe 20, the second end being reduced in diameter compared to the first end, a cooling air duct 27 from the blower is connected to the revolving portion 22 so as to introduce the cooling air in a circumferential direction of the revolving portion 22, and a flow inlet 29 adapted to cause the cooling air from the introducing portion 23 to flow into the extraction pipe is formed over an entire circumference of the outer wall of the extraction pipe 20.
