摘要
随着环保节能的重视程度提高,废弃的液压油会造成环境污染,对其进行回收再利用能够节约能源,并且起到保护环境的作用。当前,我国主要采用溶剂精制法对废弃的油进行回收,为了提高液压油的回收率和质量,文章对其溶剂精制法回收的工艺进行了改进,选择了双溶剂精制,即在糠醛溶剂中加入异丙烷从而构成双溶剂精制,通过实验研究,双溶剂精制法回收效果更好,不仅提高了回收油的质量,而且能够节约溶剂成本、提高回收效率。
With the increasing emphasis on environmental protection and energy conservation,waste hydraulic oil will cause environmental pollution.Recycling it can save energy and protect the environment.At present,in China,solvent refining is mainly used to recover waste oil.In order to improve the recovery rate and quality of hydraulic oil,the solvent refining process is improved in this paper.Two-solvent refining was selected,that is,isopropane was added to the furfural solvent to constitute a two-solvent refining.Through experimental research,the two-solvent refining method has a better recovery effect,which not only improves the quality of the recovered oil,but also saves solvent costs and improves recovery efficiency.
