摘要
通过对目前造纸工业中 6种主要造纸废液的成分对喷雾干燥工艺参数造成影响的研究 ,得出了不同造纸废液的喷雾干燥有不同的工艺条件 ,分析了废液的浓度、温度和粘度之间的相应关系 ,最后针对喷雾干燥出口温度高、热效率较低的特点 。
In this paper, the effect of chemical composition of pulping waste liquor toward the spray drying technological parameters were explored. The results showed that different technological conditions of spray drying should be adopted for different pulping waste liquor. The relations between solid content, temperature and viscosity of waste liquor were analyzed. Considering the high outlet temperature and low heat efficiency of spray drying, a new energy saving technological process was suggested, in which thin waste liquor is concentrated by using the discharged waste gas from spray drying.
