[0002] Fluid cyclone is a common separation and classification equipment, which usually uses the principle of centrifugal sedimentation. When the two-phase mixed liquid to be separated enters the cyclone from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the difference in particle size between coarse particles and fine particles, they are subject to different centrifugal forces, centripetal buoyancy, fluid drag, etc. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged from the overflow pipe, thereby achieving the purpose of separation and classification.
