摘　　要：针对目前造纸过程用能分析和仿真中未能有效集成物流、能流和流分析的缺点,采用物流、能流和流衡算方法,给出了造纸过程的通用建模方法和基本模型,建立了造纸过程物流、能流和流各自的基本抽象单元模型,给出了多物料通用能量和量计算的数学模型以及单元分析参数集,建立了水和水蒸气、干空气等的相关物性数据库,构建了集成物流、能流和分析的造纸过程通用的基本功能模块——混合模块和分离模块,为实现造纸企业全厂能量系统基于能流和物流的集成建模提供了技术和实现基础.Considering that the present energy-using analysis and simulation of papermaking process are lacking in the integrated analyses of the material,energy and exergy flows,first,the balanced calculation of the three types of flows is employed to model the papermaking process.Next,the general modeling methods as well as the basic mo-dels of papermaking process are presented.Then,the basic Abstract unit models to respectively describe the mate-rial,energy and exergy flows are established,and the general mathematical models for the energy and exergy flow calculations of multiple materials as well as an unit analysis parameter set are presented.Finally,the material pro-perty database of water,vapor,dry air,etc.,are established,and the general and fundamental functional modules to describe the mix and split of integrated analyses of the above three flows in the papermaking process are presented,thus providing a technology and implementation foundation for the modeling of the energy system for a whole papermaking mill based on the integration of energy and material flows.
