To have the tubed itself (20

摘要

PROBLEM TO BE SOLVED: To provide a solid/gas separation apparatus for granular powder by which foreign substances produced due to the pneumatic transportation is suitably separated from the granular powder and discharged from a flow-out pipe together with air.;SOLUTION: The solid/gas separation apparatus is provided with a cylindrical body 20 having an axial center in the vertical direction. The cylindrical body 20 has a cylindrical part 23 having a cylindrical shape in the upper part and a cone part 24 having an inside diameter made smaller downward in the lower part. A flow-in pipe 27 for allowing the pneumatically transported granular powder to flow in the cylindrical body is connected to the peripheral wall of the cylindrical part 23 in the tangential direction, a discharge port 25 for discharging the granular powder from the cylindrical body 20 is formed in the lower end part of the cone part 24. The flow-out pipe 29 for discharging the transporting air from the cylindrical body 20 and having the axial center in the vertical direction is connected to the upper wall of the cylindrical part 23 and the lower end part of the flow-out pipe 29 is arranged in the cone part 24. An air supply means for supplying ascending air flow into the cone part 24 from the discharge port 25 is further provided.;COPYRIGHT: (C)2008,JPO&INPIT
