Particle discharge method and device null of fluidized bed

摘要

PURPOSE: To provide the method and device in which a grain from a fluidized- bed reactor is stably discharged. ;CONSTITUTION: A moving packed bed 8 of grains is bent in the shape of a U in the grain discharge device of a fluidized-bed reactor. The packed bed 8 on the reactor side of the bent part 13 has a length sufficient to seal the reactor pressure by the pressure drop of the packed bed, and the discharge of the grain is controlled by adjusting the supply of a carrier gas from the bottom of the bent part 13 of the packed bed 8.;COPYRIGHT: (C)1995,JPO
