摘要 In order to investigate different influencing parameters acting on ultrasonic demulsification effect,a comprehensive analysis of ultrasonic intensity,dehydration temperature,acting time and emulsion water content was carried out with emulsified waste oil and machinery oil as experimental materials.Results indicate that,with ultrasonic intensity and demulsification temperature increasing,the displacement and demulsification effects of ultrasound enhance.With the increase of ultrasonic time,demulsification velocity enhances rapidly at first and then tends to slow.Water content of emulsion takes on complex influencing laws,which is depended on water droplet granularity distribution in waste oil emulsion and the characteristics of ultrasonic demulsification.Besides,oil viscosity and density affect ultrasonic demulsification greatly.The demulsification of oil with higher oil viscosity and density is less affected by ultrasound intensity,while it is sensitive to the dehydration temperature.
