【摘要】 纸幅干燥过程是制浆造纸生产过程中能耗最大的工段。对纸幅干燥过程的能量系统进行分析和优化,对提高整个造纸厂能效水平十分关键。本课题针对应用较为广泛的BF-12型卫生纸机,对其干燥部能量系统建立了机理模型,实现对通风系统的空气湿度、成纸干度以及能耗进行模拟。通过工业实际案例对模型求解结果进行验证。结果表明,本课题所提出的干燥部能量系统模型,其计算平均相对误差约为4.3%,模型具有较高的可靠性。更多还原

【Abstract】 The dryer section has the highest level of energy consumption in the papermaking process.An analysis and optimization of the energy system during the paper drying process is critical for improving the energy efficiency of the entire paper mill.The mathematical model for the energy system of the BF-12 tissue machine is proposed in this paper.The model is used to simulate the air humidity of the ventilation system,paper dryness,and energy consumption.The industrial verification results showed that the mean relative error between the simulation results and the industrial results is only 4.3%,which shows high reliability and proves its applicability for future optimization.更多还原
