APPARATUS AND METHOD FOR REGULATING A SOLID PARTICLE FLOW AND FLUIDISED BED REACTOR Russian patent published in 2022 - IPC B01J8/18 

FIELD: physics.

SUBSTANCE: inventions relate to the regulation of solid particle flows. Described is an apparatus for regulating a solid particle flow, containing a vertical inlet pipe for directing the solid particle flow downwards, the lower part whereof is at level L0; a first outlet chute and a second outlet chute in a particle flow connection with the vertical inlet pipe; and fluidisation means for directing the regulated first and second subflows formed from the solid particle flow into the first and second outlet chute; the apparatus comprises a branch in a particle flow connection with a hole in the side wall of the vertical inlet pipe, for directing the first subflow of solid particles into the first outlet chute, wherein the hole has a bottom edge at level L1, higher than L0, and the branch comprises an overflow barrier, which must be passed by the solid particles in order to reach the first outlet chute, and the hole has an upper edge at level L4, and the overflow barrier reaches level L3, higher than level L4, to create a gas seal forming a layer of particles in the branch; a horizontal intermediate pipe for directing the second subflow of solid particles into the second outlet chute, wherein the horizontal intermediate pipe comprises at least one nozzle for supplying fluidising gas into the horizontal intermediate pipe and has a first end in particle flow connection with the lower part of the vertical inlet pipe at level L0, and the apparatus comprises a vertical ascending pipe, the lower end whereof is in particle flow connection with the second end of the horizontal intermediate pipe, wherein the upper end of the vertical ascending pipe is in particle flow connection with the second outlet chute at level L2, higher than L1. Describes is a fluidised bed reactor including the above apparatus. Described is a method for regulating the solid particle flow using the above apparatus.

EFFECT: ensured regulation of the solid particle flow.
