Abstract
The invention discloses a pneumatic drying and ultraviolet sterilizing device of a circulating fluidized bed. According to the pneumatic drying and ultraviolet sterilizing device, a draught fan (1), a circulation pipe I (2), a dust remover (4), a regulating valve (5), an air inlet tee joint (6) and a circulation pipe II (7) form a circulation passage. An ultraviolet sterilizing lamp tube is arranged in the circulation passage. Under the action of airflow generated from the draught fan (1), materials are in a fluidization state and carry out circular flow in the circulation passage at a high speed, heat exchange and water exchange are rapidly carried out between the fluidized materials and the air, and then moisture is discharged out through an exhaust port of the dust remover (4). Consequently, drying of the materials is achieved, and microorganisms in the fluidized materials are killed when the fluidized materials pass the ultraviolet sterilizing lamp tube.
