New Ultrasonic Sonochemistry Machine-Ultrasonic Crude Oil Demulsifier
Ultrasonic demulsification equipment is based on the “displacement effect” of ultrasonic fluid acting on a fluid medium that is not used to achieve oil-water separation. Due to the "displacement effect", water ions will continue to move toward the antinodes or nodes, collide and collide, generating larger diameter droplets and separating them from the oil under gravity. In the standing wave field, the uneven distribution of the sound pressure results in uneven distribution of the water particles, which is more conducive to the collision of the water particles in the crude oil, thereby achieving the purpose of breaking the milk. Ultrasonic demulsification equipment mainly uses the mechanical vibration and heat of ultrasonic waves.
1. The mechanical vibration promotes the condensation of water particles. When the ultrasonic wave passes through the crude oil medium with suspended water particles, the suspended water particles vibrate together with the crude oil medium. Because the different size of the suspended water particles have different relative vibration speeds, the water particles will collide with each other and adhere to each other, so that the volume and mass of the particles will increase, and finally the sedimentation will separate.
2. The mechanical vibration can disperse the natural emulsifiers such as paraffin, colloid and asphalt in the crude oil medium, increase its solubility, reduce the mechanical strength of the oil-water interface film, and facilitate the sedimentation and separation of the aqueous phase.
3. Thermal effects can reduce the strength of the oil-water interface film and the viscosity of the crude oil. On the one hand, the boundary friction increases the temperature at the oil and water boundary, which is beneficial to the rupture of the interface film. On the other hand, the heat energy absorbed by the crude oil to convert part of the acoustic energy can reduce the viscosity of the crude oil and favor the gravity sedimentation separation of the water particles.
