Separation principle and bonding force of solid liquid separator

Jul 31, 2019

In the process of working, the solid liquid separator is mainly based on the principle of centrifugal separation. In use, it is mainly used to separate the separator which can precipitate solids in the liquid. The conventional coagulation flocculation process is a process of random collision between destabilized particles. The formed floc structure is loose, the internal void ratio is large, the density is low, and the sedimentation rate is slow. In a large number of high turbidity water purification experiments and Based on the analysis, the theory of agglomeration flocculation and the development of an upflow fluidized bed solid-liquid separator were proposed.


The solid-liquid separator can form a high-content, large-diameter sludge suspension layer under stable working conditions, and the reaction between the initial fine particles and the particles in the suspension layer after destabilization entering from the bottom is a particle. The reaction between the two kinds of particles with different diameters and contents is different. The binding force between the small particles and the suspended particles with high content and large surface area is much larger than the binding force between the small particles. The combination and growth of the particles are suspended in the fine particles. The surface of the particles is adhered one by one, so that the internal voids of the grown particles are small, the density is large, and the precipitation effect is good.
