Abstract: As oil sand cleaning agent prepared by our own, the grit carries out separation on Inner Mongolia Zha Lai Te Qi oil under ultrasonic. The effects of ultrasonic frequency, ultrasonic intensity, cleaning time, cleaning temperature of oil sand separating were investigated. The results show that under ultrasonic cavitations, under the condition of an ultrasonic frequency of 28 kHz, ultrasonic intensity of 7.06 W/cm2, the ratio of cleansing agent to oil sand 0.8∶1, system temperature 60 ℃ , cleaning time 13 min，the oil extraction rate achieve 94 %. The oil extraction rate is improved greatly under the ultrasonic wave action.

Key words: Ultrasound, Oil sand separation, Oil extraction rate

摘要： 以自制的碱液作为油砂清洗剂，在超声波下对内蒙古扎赉特旗油砂进行分离。考察了超声频率、超声声强、清洗时间、清洗温度对油砂分离的影响。结果表明，在超声波作用下，超声频率为28 kHz，超声声强为7.06 W/cm2，剂砂质量比为0.8∶1，体系温度为60 ℃，清洗时间13 min的条件下，其出油率可达到94%，超声波作用大大提高了油砂的出油率。
