Research progress on intensification technologies for fine coal flotation separation
摘要
细粒煤颗粒粒度细、比表面积大、表面能高,浮选过程中分选精度低、药剂消耗大、精煤灰分偏高.本文综述国内外细粒煤强化浮选技术及其应用瓶颈,分析选择性絮凝、载体浮选、疏水团聚等增大颗粒表观粒径的强化手段,以及微纳米气泡、超声空化、电解浮选等微泡强化浮选方法;阐述极性复配、表面活性剂、微乳液等新型捕收剂在优化颗粒界面疏水性方面的研究进展.总结现有细粒煤浮选强化技术存在的问题与局限,对细粒煤浮选技术后续发展方向进行展望.
Fine coal has fine particle size,large specific surface area,high surface energy,low separation accuracy,high reagent consumption and high ash content in clean coal during flotation.In this paper,the enhanced flotation technology of fine coal at home and abroad and its application bottlenecks are summarized,and the enhanced flotation methods such as selective flocculation,carrier flotation and hydrophobic agglomeration are analyzed,as well as the enhanced flotation methods such as micro-nano bubbles,ultrasonic cavitation and electrolytic flotation.The research progress of new collectors,such as polar compound,surfactant and microemulsion,in optimizing the hydrophobicity of particle interface is described.The existing problems and limitations of fine coal flotation enhancement technology are summarized,and the future development direction of fine coal flotation technology is prospected.
