Description

technical field [0001] The invention relates to the technical field of waste oil treatment, in particular to a double-field coupling dehydration device and a parameter optimization method. Background technique [0002] During the transportation, storage and long-term use of lubricating oil, due to various factors, it will be polluted by water, which will cause oil quality to decay and form waste lubricating oil. [0003] At present, the main methods of waste lubricating oil treatment include direct discharge, direct combustion, recycling and so on. Among them, the waste lubricating oil that can be recycled accounts for about 40% of the total consumption, which is of great significance for alleviating energy shortage, resource conservation and environmental protection. Among the many regeneration processes, the demulsification and dehydration treatment of the emulsion is a very important link. For waste oil emulsions with high water content and complex components, various s...
