摘要
乳化液的破乳脱水处理是工业废油资源化再利用工艺中的首要环节。对于含水量较高、成分复杂的废油乳化液,集成了旋流离心场和高压电场的耦合破乳脱水装置可实现单一方法无法完成的分离过程。为了提高该装置的分离效率,通过建立不同锥段结构参数下耦合装置的数值模型,并结合Box-Behnken因子设计和响应面法对耦合装置的锥段结构进行优化。结果表明:小锥角、大锥角和公称直径的最佳取值分别为5.09°、20°和22mm,在此条件下脱水率和脱油率的数值计算值分别为96.46%和97.05%。
Demulsification and dewatering treatments of the emulsion are the critical rink in the recycling technology of industrial waste oil.For the emulsion with high water content and complex composition,the coupling demulsification and dewatering device integrated swirl centrifugal and high voltage fields can achieve the separation process which cannot be accomplished by using a single method.To improve the separation efficiency of the device,the conical structure of coupling device was optimized by establishing numerical model of coupling device under different structural parameters of cone and combining with the Box-Behnken design and response surface methodology.The results show that the optimal values of large cone angle,little cone angle and nominal diameter are 5.09°,20°and 22 mm,respectively and the dewatering and deoiling rates are 96.46%and 97.05%under the optimal condition.
