| 中文摘要: |
| 通过对纸机压榨部压力和压榨脱水原理的分析，得到出压榨部纸幅干度可作为压榨部的能耗指标，同时确定压榨线压力和纸机车速是压榨部能耗的主要影响因素。结合纸机实际生产测试并记录压榨脱水数据，绘制测试数据曲线图并拟合压榨线压力、纸机车速和出压榨部纸幅干度三者之间的函数关系，最终确定压榨线压力和纸机车速的最优取值范围。通过对测试数据的分析和拟合，控制压榨线压力在90 kN/m、纸机车速在1075 m/min时，纸幅质量可满足正常生产的要求，还可以节约2.1%的电能，实现卫生纸机压榨部的能耗优化。 |
| Abstract: |
| Based on the analysis of the pressure at press section and the principle of squeezing and dewatering in paper machine， it was concluded that the dryness of pressed paper web could be regarded as the energy consumption index of press section， and the linear pressure at the press section and the speed of paper machine were the main factors affecting energy consumption of press section. Combined with the actual production test of the paper machine and the data of pressing dewatering， the test data curve was plotted. The function relation among the linear pressure at press section， paper machine speed and pressed paper web dryness was fitted based on the obtained test data curve. Finally， the energy consumption of press section was optimized by determining the optimal value ranges of linear pressure at press section and paper machine speed． Through analysis and calulation of the test data, the web quality could meet the demand of production, and the eletricity consumption could reduce by 2.1% when the linear pressure at press section and paper machine speed were 90 kN/m and 1075 m/min, respectively. |
