DEVICE FOR REACTING GAS AND GAS OR SOLID IN FLUIDIZED BED AND MANUFACTURING HEAT-SENSITIVE SOLID
1. An apparatus for reacting a gas with a gas or a solid in fluidized-bed reactor to give a heat-sensitive solid, wherein a) the cylindrical fluidized-bed reactor (1) has a conical lower section (3) whose vertex angle is from 20 to 60 degrees, preferably from 30 to 50 degrees, and the gas is passed...

| description | 1. An apparatus for reacting a gas with a gas or a solid in fluidized-bed reactor to give a heat-sensitive solid, wherein a) the cylindrical fluidized-bed reactor (1) has a conical lower section (3) whose vertex angle is from 20 to 60 degrees, preferably from 30 to 50 degrees, and the gas is passed in, via a pipe system (4), with controlled flow rectification, b) the conical lower section (3) has a single-jet nozzle (5) in order to increase the velocity of the inflowing gas to 5-50 3/s, the ratio of the free cross-section area of the cylindrical reactor (1) to that of the single-jet nozzle (5) being from 500:1 to 20:1, preferably from 300:1 to 30:1, c) the single-jet nozzle (5) has a cut-off edge (6) for the stream of gas, behind which high turbulence occurs in the peripheral region of the lower section and prevents the deposition of solid particles, it being necessary to match the exact geometry of the nozzle (5) to the particular bulk material and the gas employed, and d) heat exchangers (7) are provided inside the upper section (2) of the cylindrical reactor in order to conduct away the heat of reaction or to keep the fluidized bed at a specific temperature. |
