摘要:
这是一篇矿物加工工程领域的论文。疏水-亲水双液分选相较于泡沫浮选在微细粒（煤30～50 μm、非煤矿物10～20 μm）回收方面有较大优势。基于油团聚、奥蒂斯卡工艺、驱替脱水、双液浮选和低沸点非极性液体回收等开发的新型疏水-亲水双液分选技术（Hydrophobic-hydrophilic Separation）能够促使超细粒团聚体在双相系统中充分破碎再分配，从而达到驱水除杂的双重目的。从HHS选煤过程、团聚体破碎理论、疏水液体回收可行性、相较于泡沫浮选和油团聚的技术优势以及细粒煤脱水技术等方面对疏水-亲水分选近些年的发展进行梳理比较，以期能够为下一步发展提供参考建议。
Abstract:This is an article in the field of mineral processing engineering. Compared with foam flotation, the hydrophobic-hydrophilic two-liquid separation has a greater advantage in the recovery of ultra-fine particles (coal 30～50 μm, non-coal 10～20 μm). Based on oil agglomeration, Otiska process, displacement dehydration, dual-liquid flotation and low boiling point non-polar liquid recovery, a new kind of hydrophobic-hydrophilic dual-liquid separation technology (HHS) can promote the full fragmentation and redistribution of ultra-fine aggregates in the dual-phase system, so as to achieve the purpose of flooding water and ash reduction. In this article, the development of hydrophobic-hydrophilic separation in recent years was summarized and compared from the aspects of HHS coal preparation process, aggregate crushing theory, feasibility of hydrophobic liquid recovery, technological advantages compared with foam flotation and oil agglomeration, and dehydration of fine coal, in order to provide references for the further development.
