Title:
FLUIDIZED BED SYSTEM
Document Type and Number:
Japanese Patent JPS52142669
Kind Code:
A
Abstract:
A selected fraction of solid particles having sizes, densities and/or weights in a selected range is separated from a mixture of articles by fluidizing the mixture in a bed using a fluidizing fluid to cause particles including the selected fraction to pass out of the top of the bed; conveying the particles in a conveying fluid to a suitable separator (e.g. a cyclone) wherein the selected particles fraction is separated from smaller, lighter particles; injecting the separated fraction from the separator into a utilization zone (e.g. a fluid bed reactor); entraining other particles in the conveying fluid to another separator (e.g. a cyclone) to produce solids-free conveying fluid which is recirculated for re-use. The original particles mixture may be obtained by separation (e.g. in a cylone) from fluid leaving the utilization zone.
