本文提出了连续环状色谱床中的传递参数辨识方法、包括建立连续环状色谱轴向扩散系数的辨识模型，以惰性物作为示踪剂采用扰动－应答方法在环状色谱床中直接测定轴向扩散系数；考虑轴向扩散的作用，建立了线性吸附体系的吸附平衡常数及相间总传质系数的辨识模型，并采用扰动－应答技术进行了测定。考察了操作因素对轴向扩散系数及总传质系数的影响规律。结果表明，流体流速增加，轴向扩散系数增大，总传质系数也增大。 In this paper, a method for the identification of transfer parameters in a continuous annular chromatographic bed is proposed, which includes establishing an identification model of the axial diffusion coefficient of a continuous annular chromatogram and using inertia as a tracer to determine the axis directly in a cyclic chromatography bed using a perturbation-response method Considering the effect of axial diffusion, the adsorption equilibrium constants of adsorption system and the identification model of the total mass transfer coefficient between two phases were established. The perturbation-response technique was used to determine the diffusion coefficients. The influence of operating factors on axial diffusion coefficient and total mass transfer coefficient was investigated. The results show that the fluid flow rate increases, the axial diffusion coefficient increases, the total mass transfer coefficient also increases.
