Drawer of chlorine bypass, chlorine bypass facility, cement clinker manufacturing equipment, and manufacturing method of cement clinker

摘要

Problem to be solved: to provide a bleed device capable of reducing dust deposition and deposition and stabilizing the operation of the chlorine bypass facility.The bleed device 90 of the chlorine bypass is connected to the kiln butt 52 and / or the rising duct 51 of the cement kiln, and has a bleed pipe 12 for extracting the kiln exhaust gas 60 from the bleed opening 12a.Bleeding tube 12The cooling gas 62 is introduced along the circumferential direction.A large diameter portion 10 for mixing kiln exhaust gas 60 and cooling gasHaving an inner diameter smaller than the large diameter portionThe large-diameter portion 10 is provided on the opposite side to the bleed port 12a side and concentric with the large diameter portionThe small diameter portion 11 for deriving the bleed gas 63 including the kiln exhaust gas 60 and the cooling gas 62 andA reduced diameter portion 15 is provided between the large diameter portion 10 and the small diameter portion 11 to narrow the flow path of the large diameter portion 10.Diagram
