Structural optimization of upflow blocking prevention in shallow tank separation
In view of the problems of unsmooth and easily blocked Upwelling system of shallow trough separator in practical production,the blocking mechanism was analyzed,the factors affecting Upwelling system were explored,and the structure of Upwelling system of heavy medium shallow trough separator was optimized.The analysis and exploration results show that the viscosity of suspension and the structure of Upwelling system are all factors that affect whether the Upwelling system is blocked;The particles on the pipe wall of the Upwelling system leave in the pulling mode or rolling mode,otherwise the particles will adhere to the wall;The optimized flow distribution orifice plate and Upwelling medium hopper of heavy medium shallow trough separator significantly reduce the pipe blockage frequency of Upwelling system compared with that before the implementation of the scheme.
