摘　　要：文章对聚丙烯酸钠絮凝剂在焦化行业酚精制工艺相关的苛化反应后碳酸钙浆液沉降的促进效果进行了研究。研究发现,碳酸钙浆液沉降速度明显加快,电子显微镜影像显示CaCO3小晶体聚集成团继而相互融并成较大的晶体,抽滤后滤饼含水量明显下降。絮凝剂最佳添加量在5~10mg/m3。In this paper, the effect of sodium polyacrylate fl occulant on the sedimentation of calcium carbonate slurry after causticization reaction related to phenol refining process in coking industry was studied. The sedimentation rate of calcium carbonate slurry was obviously accelerated. The electron microscope images showed that the small crystals of CaCO3 gathered into clusters and fused into larger crystals. The moisture content of filter cake decreased significantly after filtration. The optimum adding amount of fl occulant is 5 ~ 10 mg/m3.
