摘要
选用不同浓度的焦化废水制备煤泥水煤浆。实验表明:当焦化废水浓度稀释倍数在3.3~2.5时,制备出煤泥水煤浆的稳定性、流变性能较优,最高制浆浓度为69%;煤泥水煤浆的流变性随着制浆浓度的升高而变差,且在添加剂用量为0.6%(按干基煤计算),制浆温度控制在20~30℃之间时,流变性能佳。
The slime coal water mixture(SCWM) was prepared by selecting different concentrations of coking waste water.The results showed that the rheologic ability and stability of SCWM were better than others when the dilution multiple of coking waste water was between 3.3 and 2.5,and the highest pulping concentration of SCWM was 69%;the rheologic-ability was deteriorated with the increase of pulping concentration,and the rheologic-ability was quite good when additive dosage was 0.6%(on basis of dry coal)and temperature was between 20 ℃and 30 ℃.
