摘要
An energy-saving environmentally-friendly integrated fluidized bed drying system and processing method based on multi-stage microwave heating. The drying system comprises a fluidized bed dryer (1) provided with multi-stage conveyor belts (6) and uniform distribution boards (5) therein, thus preventing material build-up in the fluidized bed, and allowing a material to be processed in a flowing state. In addition, multi-stage microwave heating is used as a thermal source, thus preventing concentration of microwave heat, and improving a drying effect. Heat in exhausts, a magnetron, and the material is recycled and reused to reduce energy waste to the lowest level. Exhausts produced from drying the material in the fluidized bed dryer (1) are condensed and introduced into a waste water treatment container (15) to be processed and then discharged, thus enabling the volatile organic compound-containing exhausts produced during drying to be treated. The present invention solves the problem of fluidized bed drying in the prior art, in which exhausts cause pollution to the environment.
