Abstract
Official abstract text for this publication.
A device for cooling a fine-grained solid includes a fluidized bed cooler/heater in which the solid is fluidized with a fluidizing gas and thereby releases energy in the form of heat within the cooler/heater at least two cyclones which are connected in parallel. The cyclones are arranged such that after the fluidization of the solid the fluidizing gas passes through the cyclones so contained particles are removed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for cooling a fine-grained solid, comprising: a fluidized bed cooler/heater in which the solid is fluidized with a fluidizing gas and thereby releases energy in the form of heat; and at least two cyclones connected in parallel and provided within the cooler/heater such that the at least two cyclones are located inside of the cooler/heater, whereby the cyclones are arranged such that after the fluidization of the solid the fluidizing gas passes through the at least two cyclones so contained particles are removed, wherein the at least two cyclones connected in parallel have a common outlet leg for withdrawing the particles from the fluidized bed cooler/heater and a sealing device adapted to seal the common outlet leg. 2. The device according to claim 1 , wherein the fluidized bed cooler/heater is divided into at least two different segments which are in fluidic contact with one another. 3. The device according to claim 1 , wherein at least one cyclone of the at least two cyclones has a tangential inlet. 4. The device according to claim 1 , wherein the outlet leg includes additional nozzles for fluidizing the separated particles. 5. The device according to claim 1 , wherein the outlet leg opens into a collecting container. 6. The device according to claim 1 , wherein the outlet leg opens into a fluidized bed of the fluidized bed cooler/heater. 7. The device according to claim 6 , wherein the outlet leg opens into the fluidized bed of the fluidized bed cooler/heater established therein during operation. 8. The device according to claim 1 , wherein the outlet leg opens into a seal pot. 9. The device according to claim 1 , wherein the outlet leg has a flap.
