麦草浆黑液提取性能试验

Experiment on extraction property of black liquor from wheat straw pulp

采用真空吸滤和挤压过滤两段组合式提取装置两次提取麦草浆黑液，能获得高且稳定的黑液提取率。探讨了黑液提取率与浆料洗涤时间、水量的关系及洗后浆所达到的洗净程度等。

High and steady extraction efficiency of black liquor from wheat straw pulp can be obtained by a two-stage extraction process using the extraction apparatus which combines vacuum filtration with press filtration. The relationship between extraction efficiency and washing time as well as water quantity,and the pulp quality after washing are investigated.
