【摘要】 造纸机的干燥部能耗占到了整个造纸过程总能耗的50%以上，建立干燥部能耗模型并对其能耗进行优化，对提高整个造纸过程能源效率有着重要意义。纸张干燥是一个复杂的工业过程，现有的纸张干燥模型大部分只是针对纸张干燥过程，并没有把干燥部当作整个系统去考虑。本文针对双挂烘缸建立纸张干燥模型，并对机理模型中拟合较差的部分使用数据驱动模型进行修正，修正后的模型MAPE平均降低了5%。最后基于混合模型对纸张干燥过程进行优化，优化结果每吨纸可节省4%的蒸汽使用。更多还原

【Abstract】 The energy consumption of the drying part of the paper machine accounts for more than 50% of the total energy consumption of the whole papermaking process. It is of great significance to establish the energy consumption model of the drying part and optimize its energy consumption to improve the energy efficiency of the whole papermaking process. Paper drying is a complex industrial process,most of the existing paper drying models only focus on the page drying process, and do not consider the drying part as the whole system.In this paper, a paper drying model was established for the double hanging dryer, and the poor fitting part of the mechanism model was modified by using the data-driven model, and the MAPE of the modified model decreased by 5% on average. Finally, the paper drying process was optimized based on the hybrid model, and 4% steam consumption per ton of paper was saved.更多还原
