Fluidized bed drying device and fluidized bed drying equipment

摘要

This fluidized bed drying device or fluidized bed drying equipment includes: a hollow drying vessel (101), a raw coal inlet (102) on one end of the drying vessel (101) to introduce raw coal, a dried coal outlet (103) to discharge, from the other end of the drying vessel (101), dried coal obtained by heat drying raw coal, a fluidization gas supply portion (104) that forms a fluidized bed (S) with raw coal by supplying fluidization gas to the lower part of the drying vessel (101), a gas outlet (105) that releases fluidization gas and generated steam from a higher point than the raw coal inlet (102) formed on one end of the drying vessel (101), a heat transfer tube (106) that heats the raw coal in the fluidized bed (S), and an inclined plate (111) that leads fluidization gas and generated steam to the gas outlet (105) by guiding fluidization gas and generated steam from the dried coal outlet (103) side to the raw coal inlet (102) side.
