Solid-liquid mass transfer in a Peirce-Smith converter: A physical modelling study

摘要: Pyro-metallurgical processes are multiphase in nature involving gas-liquid-solid interactions. In the Peirce-Smith converter operation, additions of cold solids liquid matte form fluxing agents (silica sands) for slag liquidity, process scrap and reverts temperature control is a common practice. It reasonable to postulate that with such practice, solid-liquid mass transfer step may play an important role performance attainment bath homogeneity process. this work, solid were simulated sintered benzoic acid compacts spatially positioned 1:5 water model converter. Water kerosene used simulate respectively. Solid-liquid was characterized by experimentally determined coefficient, K (ms-1) values calculated dimensionless turbulence characteristic, Tc values. The coefficients characteristic highest at surface near plume region. decreased identified dead zones regions close circular side walls model. results revealed characteristics different respect submergence levels compacts. These findings lead conclusion fluid flow stratified within vessel.
