Fluent-based Copper Flash Smelting Many Simulation

Flash smelting technology has become the mainstream technology of copper smelting,copperflash smelting process simulation research in frontier areas of copper smelting, computersimulation technology is a comprehensive discipline, in addition to the field of simulation required to have a solid theoretical foundation and rich practice in the field, but also requires computer technology and related disciplines (such as calculation, combustion science, fluid mechanics, etc.) have a deep understanding of the copper flash smelting furnace simulation study purpose is to raise labor productivity, achieve energy saving. As indicators of copper flash smelting requirements increase, further increase the level of copper flash smelting processing increasingly important.In this paper, the Jinlong Copper Flash Furnace as a research object, to deepen the process of copper flash smelting reaction mechanism and chemical reactions occurring awareness and understanding, through independent development of complex chemical equilibrium composition computer program concentrates phase analysis carried out to establish the material properties of copper smelting materials database, to facilitate the simulation for the flash smelting. FLUENT and the second development. Is calculated by FLUENT commercial software platform for flash smelting of the temperature field and concentration field, particle field and other field simulation.The simulation study found that:(1) concentrates particles in the reaction tower can rapidly be oxidized, while making complete reaction of sulfur, molten particles at a faster rate into the sedimentation tank, larger particle size the faster the sedimentation tanks arrived.(2) concentrate the temperature in the reaction tower rapid warming occurred in the central oxygen under high temperature, the temperature below the highest point in the burner, there was a delegation of the central nozzle temperature region.(3) areas with high concentrations of SO₂ in the central sedimentation tank until the nozzle below the bottom of the outside of SO₂ in the thick umbrella of particles is relatively low; the central region of oxygen below the basic oxygen consumption completely, outside and smoke in the region near the exit about 7% to 8% did not consume oxygen.
