摘要
利用高硫物料代替部分煤在湿法锌浸出渣火法回收处理过程中优势明显,一方面硫燃烧产生大量的热可满足火法冶金生产过程中的热量需求,减少煤的消耗量,降低企业碳排放总量;另一方面硫燃烧产生的SO_(2)可用于生产硫酸等化工产品,增加企业副产品产量,提高盈利能力,实现资源回收利用,降低企业生产成本。随着国家加快推进碳达峰、碳中和进程,在火法冶金过程中利用其他热源代替煤已经成为行业趋势,如何在火法冶金行业发展“低碳经济”,达到低能耗、低排放的目标可谓任重而道远。因此,开展高硫物料在湿法锌浸出渣火法回收处理过程中代替原煤的生产实践研究具有重要的现实意义。
Replace part of the coal in the wet zinc leaching slag thermal recovery process using highsulfur materials,the advantages are obvious,on the one hand,sulfur combustion produces a large amount of heat to meet the heat demand in the pyrometallurgical production process,reduce coal consumption,reduce the total amount of carbon emissions;on the other hand,sulfur combustion of SO_(2)can be used for the production of chemical products such as sulfuric acid,increase the output of byproducts,increase profitability,and achieve resource recycling.On the other hand,SO_(2)from sulfur combustion can be used to produce chemical products such as sulfuric acid,which increases the output of by-products,improves profitability,achieves resource recycling and reduces production costs.As the country accelerates the process of carbon peak,carbon neutrality process,in the process of pyrometallurgy,the use of other heat sources instead of coal has become an industry trend,how to develop“low carbon economy”in the pyrometallurgy industry,to achieve the goal of low energy consumption,low emissions can be said to be a heavy load and a long way to go.Therefore,it is of great practical significance to carry out the research on the production practice of high-sulfur materials replacing raw coal in the process of thermal recovery and treatment of wet zinc leaching slag.
