Analysis of mechanism of flash smelting reaction process

本文从闪速熔炼炉反应塔、沉淀池烟气区、上升烟道及锅炉内部化学反应,及闪速熔炼精矿颗粒行为等角度,结合金冠闪速熔炼系统实际生产工况,分析了锅炉出口温度、硫酸废酸浓度、烟尘发生率及渣含铜的影响因素,进一步分析了金冠闪速炉锅炉粘结、硫酸废酸浓度、烟尘发生率和渣含铜升高的原因,提出了减少锅炉粘结、降低硫酸废酸浓度、降低烟尘发生率和降低渣含铜的措施。

This article from the flash smelting furnace, reaction tower, sedimentation tank area, flue gas flue and increased chemical reaction inside the boiler, and the angle of flash smelting particle behavior, combined with the actual production conditions of golden flash smelting system, analyzes the influencing factors of the boiler outlet temperature, sulfuric acid concentration, the incidence rate of waste dust and slag containing copper, further analysis of the causes of boiler, waste sulfuric acid flash gold bonded acid concentration, soot and incidence of copper slag increased, proposed to reduce the boiler, reduce waste sulfuric acid bond concentration, reduce the smoke and reduce the incidence rate of copper slag containing
