运用闪速炉反应塔“高效反应区”模型,研究闪速炉操作的优化与强化。结果表明,形成“高效反应区”的主要条件是高温、氧气和颗粒群的集中。“高效反应区”模型在生产中的初步应用获得了显著效果。“高效反应区”的形成有利于强化生产、降低油耗和烟尘率、延长反应塔寿命、提高氧利用率和铜直收率。 The flash reactor’s “high efficiency reaction zone” model was used to study the optimization and strengthening of flash furnace operation. The results show that the main conditions for the formation of “efficient reaction zone” are the concentration of high temperature, oxygen and particle swarms. The initial application of the “efficient reaction zone” model in production has yielded significant results. The formation of “efficient reaction zone” is conducive to strengthening production, reducing fuel consumption and smoke and dust, extending the life of the reactor tower, and improving the oxygen utilization rate and copper yield.
