针对氧化还原功能纤维回收贵金属过程为扩散、传质控制的事实，提出用传质传热速率高的流态化技术强化该过程。初步考察了流态化强化功能纤维回收贵金属的过程机制，阐述了功能纤维流态化过程系统的特点。在此基础上，研究分析了该过程系统的传质和传热行为，并建立了相关的数学模型，为该过程实际应用提供依据。 In view of the fact that the recovery of precious metals by redox functional fibers is controlled by diffusion and mass transfer, it is proposed to strengthen the process by the fluidization technique with high mass transfer and heat transfer rate. The mechanism of recovery of precious metals from fluidized reinforcing fibers was first investigated, and the characteristics of the fluidized fiber processing system were expounded. On this basis, the mass transfer and heat transfer behaviors of the process system are studied and analyzed, and the related mathematical models are established, which provide the basis for the practical application of the process.
