一、前言麦草蒸煮工序是整个造纸过程中的关键工序之一。在这一工序中,要消耗大量的电、蒸汽及化工原料。蒸煮工艺的优劣,直接影响到成品纸的质量和成本。近几年来,造纸行业经过反复试验,总结出了“慢升温快蒸煮新工艺”,其蒸煮过程中,蒸球中压力和蒸煮时间有如图1所示的关系。实践证明,这种蒸煮工艺的优点:得浆率高,纤维较长,大大节约能源及化工原料,并且能缓和蒸球用汽高峰对锅炉的影响。但是,目前大多数造纸厂蒸煮工序的控
First, the prelude Wheat straw cooking process is one of the key processes in the entire papermaking process. In this process, to consume a large amount of electricity, steam and chemical raw materials. The pros and cons of cooking process, a direct impact on the quality and cost of finished paper. In recent years, the paper industry after repeated tests, summed up the “slow heating fast cooking new technology”, the cooking process, the steam pressure in the ball and cooking time as shown in Figure 1 relationship. Practice has proved that the advantages of this cooking process: pulp rate was high, longer fibers, greatly saving energy and chemical raw materials, and steam boil steam peak can ease the impact of the boiler. However, most of the current paper-making process controls
