为探索水合阳离子对煤泥矿物颗粒表面水化的微观影响机理,以煤泥中主要矿物高岭石和石英为研究对象,依据煤泥水溶液环境构建了[Na(H_(2)O)_(5)]+及[Ca(H_(2)O)_(8)]^(2+)两种煤泥水中常见的水合阳离子构型,并采用密度泛函理论对这2种水合阳离子在高岭石(001)面、(001)面和α-石英(001)面的单一吸附及与水分子间的竞争吸附进行了模拟计算。模拟结果表明,单一水合阳离子在3种表面的吸附能均比水分子的吸附能低出50%以上,其在矿物表面的吸附稳定性顺序为:α-石英(001)面>高岭石(001)面>高岭石(001)面;在竞争吸附作用下,竞争稳定构型的吸附能比单一水合阳离子在高岭石、石英表面上的吸附能低出34%~57%,其中2种吸附条件下[Ca(H_(2)O)_(8)]^(2+)构型均比[Na(H_(2)O)_(5)]+构型更稳定。水合阳离子在3种表面上单一吸附时,与表面形成强氢键作用,比水分子与高岭石、石英表面间的氢键作用更强,2种水合阳离子在矿物表面的氢键强弱顺序均为:高岭石(001)面>α-石英(001)面>高岭石(001)面;在竞争吸附作用下,[Na(H_(2)O)_(5)]+与矿物表面间的氢键作用增强,[Ca(H_(2)O)_(8)]^(2+)与矿物表面间的氢键作用减小;由于氢键作用不能完全对应吸附能的变化,经分析可知,吸附构型中存在静电作用,水合阳离子单一吸附构型中的静电作用比水分子吸附时更强,而在竞争吸附作用下,水合阳离子与矿物表面间静电作用增强,同时[Ca(H_(2)O)_(8)]^(2+)比[Na(H_(2)O)_(5)]+与对应矿物表面间的静电作用更强。由于水合阳离子在高岭石、石英表面的强吸附作用,导致煤泥颗粒脱水更加困难,同时可能增加颗粒间的水化斥力,从而导致颗粒在煤泥水中分散更稳定。

煤泥颗粒表面水化是煤泥脱水困难的重要因素之一,通过弱化煤泥颗粒表面水化膜促进煤泥高效脱水是一种新的技术方法。为掌握基于弱化水化膜促进煤泥脱水机理,采用密度泛函理论方法模拟了不同长链烷基季铵阳离子(表面活性剂)在煤泥水主要矿物颗粒表面的吸附,通过对吸附构型、Mulliken键布局及电荷的分析,研究了水及药剂在高岭石(001)面、α-石英(001)面和蒙脱石(001)面的吸附机理;通过开展煤泥脱水试验和接触角测试,探讨长链烷基季铵盐药剂对煤泥水分和表面润湿性的影响规律。结果表明,水分子在不同种类矿物(001)面的吸附稳定性顺序为石英>高岭石>蒙脱石,石英对煤泥脱水影响大于高岭石和蒙脱石;长链烷基季铵盐药剂在矿物表面的吸附稳定性明显高于水分子,说明药剂与水分子的竞争吸附作用顺序是蒙脱石>石英>高岭石;长链烷基季铵盐与几种矿物(001)表面吸附均是以静电引力为主,弱氢键为辅。随着长链烷基季铵盐药剂用量的增加,煤泥滤饼水分先减少后增加,当药剂用量为500 g/t效果最好,水分降低2.25%以上;随着药剂用量和链长的增加煤泥表面疏水性显著增加。控制药剂用量是实现高效煤泥脱水的技术关键,添加适量的表面活性剂有利于弱化矿物表面的水化膜,过量长链烷基季铵盐阻碍煤泥脱水。

为实现黏土矿物颗粒界面疏水调控进而提高难沉降煤泥水处理效果,研究了水分子在铵伊利石表面的吸附机理.采用密度泛函理论方法对水分子在铵伊利石有晶格取代的(001)面和不存在晶格取代的(001)面上的吸附进行模拟计算.结果表明:水分子在(001)面吸附的最强活性点位于晶格取代原子Al成键的氧原子处,吸附最稳定的水分子垂直于有NH_4^+的硅氧环,并与NH_4^+和活性原子形成共2个氢键作用,吸附能为-0.67eV,且水分子有将NH_4^+拉离(001)面的趋势;水分子在(001)面的最稳定吸附主要是位于硅氧环空穴上方,水分子与表面氧原子形成3个氢键,吸附能为-0.41eV.2种最稳定吸附均存在微弱的静电吸附.选择合适的阳离子型疏水药剂与NH+4发生交换吸附,覆盖(001)面活性点,破坏水分子的稳定吸附,理论上可实现铵伊利石等黏土类矿物颗粒界面的疏水调控.
