摘要
为探究最佳药剂合成方案,采用激光粒度分析仪、电泳仪、X射线衍射仪、X射线荧光光谱仪分析某选煤厂煤泥水性质,探讨高泥化煤泥水形成的原因。运用单因素和正交实验相结合的方法寻找絮凝剂CPBA的最佳合成方案,分析在不同条件下絮凝剂和聚合硫酸铁对煤泥水颗粒的作用机理。结果表明:高泥化煤泥水的形成是由于煤泥中微细颗粒物含量较高,黏土类矿物较多。絮凝剂CPBA单独使用时,煤泥水沉降迅速,但是沉积层厚度较大,药剂用量过多则会取得反效果。絮凝剂CPBA和聚合硫酸铁配合使用能够提高煤泥水沉降效果,降低上清液浊度,降低药剂的使用量。
This paper is intended to explore the best pharmaceutical synthesis program. The explora- tion is accomplished by analyzing the properties of coal slime in a coal preparation plant using laser parti- cle size analyzer, clectrophoresis, X-ray diffractometer , and X-ray fluorescence spectrometer and investi- gating the reasons behind the formation of high muddy coal water; and developing the best synthesis scheme of flocculant CPBA using single factor experiment and orthogonal experiment and thereby identif- ying the mechanism underlying flocculant and polyferric sulfate on coal slime particles under different conditions. The results demonstrate that the formation of high muddy mud is attributed to the higher con- tent of fine particles and more clay minerals in the slime; the use of the floceulant CPBA leads to a rapid slime water settlement, but with the greater thickness of the sedimentary layer, and a greater pharmaceu- tical use is more likely to yield an opposite effect; and the combined use of Flocculant CPBA and polyfer- ric sulfate could contribute to an improved effect on the slime water sedimentation, with a resultant reduc- tion in the supematant turbidity ands the amount of flocculant used.
