Simulation and Optimization of Melted iron Desulfurization Process in Torpedo with Blowing Gas and Spray
According to the practical physical dimension and processing parameters of torpedo in a factory, Eulerian multiphase model was applied and adopting porous media model for the gas flow through the porous refractory, desulphurization process model was coupled, the desulphurization process of melted iron in torpedo with bottom blowing were computed using mathematical simulation approach, effect of bottom blowing technique was discussed. The results show that: Compared with the desulphurization behavior of melted iron in torpedo without bottom blowing, porous refractories were located at the bottom of torpedo in order to mixing melted iron by blowing gas, even using 30m3/h gas flow rate, desulphurizing result is improved. As the gas flow rate increased, the desulphurizing result become better. The desulphurizing result of bottom blowing between inlet and the end at the bottom of torpedo is better, especially the position of 2500mm. Blowing in 260s after the end of dust can avoid resulfuring and decrease sulfur content.
