摘要:目前生活用纸的干燥部常采用扬克烘缸干燥系统。本研究以环境温度和湿度以及容易采集的工艺操作参数为输入,建立了扬克烘缸干燥能耗与干燥速率的软测量模型,并将该模型在国内生活用纸纸厂广泛使用的BF系列纸机上进行了工业验证。结果表明,干燥速率与蒸汽流量平均误差分别在3%与5%以内。由此可见,本研究建立的软测量模型具有较好的可靠性,可为生产精细化管理提供科学依据。
Abstract:The drying section has the highest energy consumption in tissue paper machine. Besides, it is also one of the key processes to control the quality of the products.How to reduce the energy consumption of drying section and ensure the product quality is a hot issue in the industry.Taking environment temperature and humidity and accessible operational parameters as model input, this study proposed a soft sensing model to simulate the energy consumption and drying rate of Yankee drying system which is a common drying method for tissue paper at present.The proposed model has been applied to BF paper machines under various production conditions.The results indicated that the average errors of drying rate and steam flow rate were are less than 3% and 5% respectively,it verifies the reliability and accuracy of the model, which could be used to supply the scientific basis for the drying process optimization.
