摘要
植物油脱色废白土是粉末状物料,现有制油工艺和设备难以回收其中的油脂,关键是混合油中的固液分离困难。本研究指出混合油是非水介质悬浮液,存在扩散双电层,故混合油体系稳定,采用投加某种凝聚剂,使悬浮液中的固粒产生吸附-电中和作用,固粒可迅速聚沉。在此基础上应用高效节能的卫星式浸出器可进行连续化工业生产。
Waste clay for vegetable oil decolorization is powder. The difficulty to recover the oil from the existing process and equipment at present is that of solid liquid separation in mixed oil. Mixed oil is non-aqueous medium suspension,which has diffusion double layers,so the mixed fluid system is stable. Adding some kind of coagulant to make solid particles in suspension would produce adsorption electric neutralization,which would cause the gathering of solid particles. In this case,high efficiency and energy saving satellite leaching device can conduct continuously in industrial production.
