Packed bed, moving bed, and multistage fluidized bed device having swing mechanism and enabling uniform contact between gas and powder

Abstract

Embodiments of the present disclosure relate to a powder bed including at least one pair of plates including a horizontally swinging perforated plate and a static perforated plate inside a packed bed or a moving bed that is aerated from below. In some embodiments, the swinging perforated plate may be configured to move horizontally relative to a horizontal plane so as to transmit a horizontal swinging motion to the powder. In some embodiments, the powder bed including the at least one pair of plates may improve uniform gas-solid contact in packed beds, moving beds, or multi-stage fluidized beds using highly cohesive, easily consolidated, or compacted powder. Further, in some embodiments, the powder bed may decrease consolidation and compaction of the powder in the powder bed.
