为解决废油分离困难、耗时、耗能大的问题，对超声对油包水乳状液的脱水破乳工艺进行了研究，包括温度、破乳剂、沉淀时间、超声辐照时间、声强、声频等。与传统破乳方法相比，超声破乳具有节能、高效的优点。最佳破乳条件为：60℃，超声辐照5 min，声强为0.66 W·cm−2，沉淀6 h，可实现本研究乳剂的良好脱水性能，水含量可降至0.1%。
In order to solve the difficulty of waste oil separation, time consuming and high energy consumption, the dehydration and demulsification process of water-in-oil emulsions by ultrasound was studied, including temperature, demulsifier, settling time and ultrasonic irradiation time, sound intensity, and acoustic frequency. Compared with traditional demulsification methods, ultrasonic treatment shows the advantages of energy saving and high efficiency. Optimum conditions for demulsification are obtained at 60°C, ultrasonic irradiation for 5 min when the sound intensity is 0.66 W·cm−2, settling for 6 h, then good performance can be realized to dehydrate the emulsions in this study that the water content can be reduced to 0.1%.
