Basic working principle of Desilter Hydrocyclones
Desilter Hydrocyclones is a common separation and classification equipment, and the principle of centrifugal sedimentation is commonly used. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the Desilter Hydrocyclones 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 affected by centrifugal force, centripetal buoyancy, fluid drag, etc., and due to centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow outlet of the cyclone, while most of the fine particles are discharged by The overflow pipe is discharged, so as to achieve the purpose of separation and classification.
As a typical equipment of centrifugal force and gravity composite force field, it is widely used in many fields because of its simple structure, small footprint, convenient installation and operation, and low operating cost.
The basic principle of Desilter Hydrocyclones is to separate liquid-liquid, liquid-solid, liquid-gas and other two-phase or multi-phase mixtures with a certain density difference under the action of centrifugal force. The mixed liquid is tangentially entered into the Desilter Hydrocyclones at a certain pressure, and a high-speed rotating flow field is generated in the cylindrical cavity. Under the action of the swirl field, the components with high density in the mixture move downward in the axial direction, move outward in the radial direction, and move down along the wall of the vessel when they reach the cone section, and are discharged from the underflow port, thus forming The outer vortex flow field is formed; the components with low density move toward the central axis, and form an upwardly moving inner vortex at the center of the axis, which is then discharged from the overflow port, thus achieving the purpose of two-phase separation.
