摘要： A fluidized bed type spent activated carbon regenerator with an upper drying chamber and a lower reactivating chamber within a column through which spent activated carbon particles are treated in a fluidized state. The regenerator has a distributor at the lower end of a spent carbon feed pipe which opens into the upper chamber to distribute the feed of spent activated carbon uniformly on all sides of the feed pipe and over a larger area in the upper chamber. A hood is mounted around an upper end of a first overflow pipe which provides a passage to the lower chamber for carbon particles devolatilized in the upper chamber to block shortpasses of incompletely devolatilized carbon particles to the lower chamber. The regenerator is further provided with a louver strainer at the ceiling of the upper chamber to block fine carbon powder which tends to leave the regenerator entrained in upward streams of a regeneration gas flowing through the upper chamber toward a gas outlet at the top of the regenerator.
