White carbon black drying system using fire coal circulating fluid bed hot-air furnace

The invention relates to a white carbon black drying system using a coal-fired circulating fluid bed air heating furnace, which comprises a circulating fluid bed air heating furnace system that is provided with a heat exchange surface in the furnace for controlling combustion temperature and co-producing steam, a flue gas reverse-flow system used for regulating the flow rate of the flue gas of a hot air heat exchanger and recovering the waste heat and a white carbon black sizing agent drying system used for exchanging the heat of clean air and the hot air heat exchanger and recovering the heat of tail gas of a dryer. The invention takes coal as fuel, the fuel is low in cost and wide in source, and multiple systems can be used for recovering and utilizing heat energy, so that the thermal efficiency is high, the energy consumption is low, the drying effect of the white carbon black is good, and the service life of the air heating furnace and the heat exchanger is long.
