摘要
为了探讨纳米气泡对煤炭浮选的影响,据众多研究表明,纳米气泡的桥力作用可以促进煤炭颗粒粘结,纳米气泡的气液界面和内部高压可以促进气泡矿化,纳米气泡的低密度可以使煤炭颗粒的沉降速度降低。据此,构建了煤炭颗粒在水中存在的模型及矿化过程模型,并用此模型解释了选药剂、充气量、叶轮转速对浮选效果的影响,得出了基于纳米气泡的影响解释煤炭浮选的规律。
To illustrate the effects of nanobubbles on coal flotation, this article assumed that nanob/Jbble bridging capillary force promotes the particle coagulation and mineralization, and nanobubbles can make the sediment velocity of particles lower, then built a model of coal particle in water, and using the model explained the effect of frother, aeration and rotation rate on flotation. Nanobubble-based coal flotation model was predicted and validated.
