碱法蒸煮麦草浆黑液提取,若采用4台鼓式真空洗浆机串联逆流洗涤后,再筛选净化,则造成工艺流程加长,稀释因子大,动力消耗增加等弊端。通过改进和实践,对碱法连蒸麦草浆采用了“三加一”提取新工艺,运行效果十分显著。流程如图1. Alkaline steaming straw liquor black liquor extraction, if the use of 4 drum vacuum pulp washer series countercurrent washing, and then screening purification, resulting in longer process, dilution factor, increased power consumption and other drawbacks. Through the improvement and practice, the new technology of “three plus one” was used to extract the wheat straw from Alkaline Process, the running effect was very significant. Process shown in Figure 1.
