摘要
针对目前油砂分离研究中存在的问题,提出了油砂超声分离的新方法。结果表明,在超声条件下,超声空化状态对油砂分离的效果有很大影响,油砂分离的最佳空化状态为弱空化状态。考察了超声频率、功率、作用时间、温度对油砂分离的影响,通过正交实验优化得到油砂超声分离的最佳工艺条件为:超声频率40 kHz、功率50W、作用时间20 min、温度50℃。在此条件下,油砂出油率达94%以上,证实了油砂超声分离在技术上是可行的。
The method for detaching oil sand by ultrasonic was put forward aiming at the problems which oil- sand separation. The results show that the state of ultrasonic cavitation has large influence upon the effect of oil removing from oil sand, and the best state of ultrasonic cavitation is weak ultrasonic cavitation. The effects of the ultrasound frequency, power, time, temperature on the separation of oil and sands were studied. From orthogonal test, the optimum conditions of oil--sand separation are the ultrasonic frequency 40 kHz, utrasonic power 50 W, operative temperature 50 ℃ and treatment time 20 min. The removal rate of oil from oil sand is above 94% at this condition. It is show that the method for detaching oil sand by ultrasonic is feasible.
