| 摘 要： | 为提高褐煤制气化水煤浆的制浆浓度,采用传统制浆工艺与分级研磨制浆工艺分别对某化工企业提供的3种煤样进行水煤浆成浆性实验,并在此基础上进行配煤制浆实验。结果表明:东明煤、扎赉诺尔煤、宝矿提质煤传统制浆工艺的最高浓度分别为48.54%、51.76%、56.08%,分级研磨制浆最高浓度分别为51.72%、54.82%、59.21%,3种煤样分级研磨制浆工艺水煤浆浓度提高3%以上。按照东明煤、扎赉诺尔煤质量比1∶1或东明煤、宝矿提质煤质量比2∶1配煤时所制水煤浆浓度分别为53.12%、54.21%,满足水煤浆浓度设计要求。

| Abstract: | In order to improve the concentration of coal water slurry （CWS） for gasification with lignite,the slurryability of three coal sam-ples which were provided by an chemical enterprise was conducted through traditional CWS preparation process and classified grinding process.Then the CWS preparation with blending coal was carried out.The results showed that,prepared by traditional process,the highest pulp concentration of Dongming coal,Zhalainuoer coal,Baokuang upgrading coal were 48.54%,51.76%,56.08%.Prepared by classified grinding process,the highest pulp concentration of above three CWS were 51.72%,54.82%,59.21%,which were above 3% higher than the concentration of CWS prepared by traditional process.When the mass ratio of Dongming coal and Zhalainuoer coal was 1 to 1,or the mass ratio of Dongming coal and Baokuang upgrading coal was 2 to 1,the concentration of CWS were 53.12% and 54.21%,which met the design requirements. |
