要实现工业结晶过程新工艺和设备的开发以及过程操作的优化,就必须建立涉及结晶过程特性并反映结晶器流动、混合和传递规律及其相互作用关系的结晶器总体数学模型。过去几十年中已有许多研究者进行了这方面的探索,提出了各种各样的模型。特别是70年代初由Randolph和Larson提出的粒数衡算模型,将产品的粒度分布与结晶器的结构参数和操作参数联系起来,成为结晶器设计、放大和优化从经验上升到科学的重要标志。 针对不同结晶系统提出的多种数学模型中,最具典型代表性的数学模型是由Mullin等提 To realize the development of new technology and equipment for industrial crystallization process and the optimization of process operation, it is necessary to establish a general mathematical model of the mold, which relates to the characteristics of crystallization process and reflects the laws of flow, mixing and transfer of crystallizers and their interaction. In the past few decades, many researchers have conducted exploration in this area and put forward various models. Especially in the early 70s by Randolph and Larson proposed grain balance model, the product size distribution and the structure of the mold parameters and operating parameters linked to become the mold design, enlarge and optimize the rise from experience to an important symbol of science . Among the various mathematical models proposed for different crystalline systems, the most typical mathematical model is proposed by Mullin et al
