Particle self-rotation is a common phenomenon in the natural environment and industrial fluids. The particle surface renewal and centrifugation caused by particle self-rotation are the inherent mechanisms that enhance the desorption of pollutants. In this paper, a motor and rotary shear flow field are used to drive the self-rotation of the porous media Maifan stone particles and soil particles, respectively. An experimental device for active and passive particle self-rotation control is established to determine the driving parameters that influence the relationship between the diesel desorption efficiency of particles and particle self-rotation. Active self-rotation increased the diesel desorption efficiency of Maifan stone particles by approximately 65.1%. Alternating active and passive self-rotation, self-rotation speed, and temperature were positively correlated with diesel desorption efficiency. Passive particle self-rotation in the rotating shear flow field achieves balanced desorption efficiency in a single pass through the hydrocyclone. The desorption efficiency of underflow particles is approximately 50% higher than that of overflow particles. The experimental results show that both active and passive self-rotation can improve the diesel desorption of particles and suggest the possibility of reducing the amount of surfactant used.

粒子自转是自然环境和工业流体中的普遍现象。粒子自转引起的粒子表面更新和离心是增强污染物解吸的内在机制。本文采用电机和旋转剪切流场分别驱动多孔介质麦饭石颗粒和土颗粒自转。建立了主动和被动颗粒自转控制实验装置，确定了影响颗粒柴油解吸效率与颗粒自转关系的驱动参数。主动自转使麦饭石颗粒的柴油解吸效率提高了约65.1%。交替的主动和被动自转，自转速度，和温度与柴油解吸效率呈正相关。旋转剪切流场中的被动粒子自旋转在单次通过水力旋流器时实现平衡解吸效率。底流颗粒的解吸效率比溢流颗粒的解吸效率高约50%。实验结果表明，主动和被动自旋都可以改善柴油对颗粒的解吸，并提出了减少表面活性​​剂用量的可能性。
