摘　　要：本文研究了5种有机废液的水煤浆制备特性,并在有分散剂和无分散剂条件下与清水对比了各废液的制浆性能。结果表明:本文涉及的5种有机废液,在添加0.3%分散剂的条件下,制备得到最优水煤浆浓度较清水高2%~4%;在无分散剂条件下,几种废液也可制备得到满足气化要求的水煤浆;制备得到的水煤浆表观粘度都随浓度升高而增大,且丙烯酸丁脂浓废液和固定床浓缩废液水煤浆表观粘度增大趋势更加陡峭。The preparation characteristics of coal water slurry(CWS)of five kinds of organic waste liquid are studied,and the pulping performance of each waste liquid with and without dispersant is compared with that of clean water.The results show that:the five kinds of organic waste liquid involved in this paper,in the condition of adding 0.3%dispersant,the optimal concentration of coal water slurry is 2%~4%higher than that of clean water.In the absence of dispersant,these waste liquid are also prepared to qualified coal water slurry which meets the gasification requirements.The apparent viscosity of the coal water slurry increases with the increase of the concentration,and the increase trend of coal water slurry which is prepared with the concentrated waste liquid of butyl acrylate and fixed bed concentrated waste liquidis is more steep.
