摘要
介绍了一种苛化工段直接生产沉淀碳酸钙的新技术。该技术通过对传统造纸黑液碱回收苛化工序的关键性技术改造,如:增设石灰净化处理过程及绿液净化处理过程等,不仅避免了废渣(白泥)的产生,而且在回收碱的同时还直接生产出了沉淀碳酸钙。
A new technology for producing PCC directly in the causticizing stage is reported in this paper.By improving the technology of causti-cizing in traditional alkali recovery process,the technology can not only avoid the pollution of lime mud but also directly produce the PCC while the alkali is recovered.
