| 中文摘要: |
| 基于三段通汽式干燥部工艺流程，在“输入已知、输出未知”和“先烘缸、再通风、后纸张”的原则指导下，以烘缸组为最小建模单元，根据序贯模块法的基本思路，构建了纸机干燥部的静态模型。以某新闻纸机干燥部为对象进行模拟，给出了进出各模块的物流和能流信息，模拟结果与该纸机实际运行情况基本一致。该模型符合纸机干燥部工艺流程，可以用来模拟各模块之间的物流和能流信息，便于为干燥部用能分析提供依据。 |
| Abstract: |
| Based on the drying process of three-stage steam heating paper machine dryer section, a static model for paper machine dryer section was developed using sequential modular approach. The input parameters of the model were known and the output parameters were unknown. The dryer group was chose as the basic modeling unit. The cylinder modular, ventilation modular and paper modular were built consequently according to the drying techniques. As a case study, the static model of a newsprint machine dryer section was then constructed according to its specific drying process and conditions. The mass and energy flows information of each basic modular were presented in the results. The simulated results were basically consistent with the practical operation of the paper machine. The model was in line with the drying techniques and it could be useful for energy analysis in dryer section. |
