摘　　要：针对提钒工艺中的关键环节,采用METSIM软件对含钒钢渣加压强化提钒工艺进行了工艺建模和物料衡算,得到了整个工艺过程中各物流的质量流量以及所包含的物质的详细信息。模拟过程可清晰了解每种物质详细走向,为工艺的设计及优化提供参考。结合上述模拟结果和产线实际运行中存在的蒸发水量较大的问题,设计了优先处理尾渣中钒酸钙,其次再进行优化尾渣洗涤的方式。结果表明通过模拟分析可进一步优化实际工艺方案,模拟结果使提钒工艺中总用水量减少7552 t/a,蒸发水量减少7521 t/a,显著降低了提钒工艺能耗。In this paper, in view of the key steps in the vanadium extraction process, METSIM software was used to carry out the process modeling and material balance in the extraction process from vanadium bearing steel slag using pressure strengthening, and the mass flow rate of each logistics and the detailed information of the substance in the whole process were obtained. The simulation process could clearly understand the detailed trend of each substance, and provided a reference for the design and optimization of the process. Combined with the above simulation results and the problem of large amount of evaporative water in the actual operation of the production line, the calcium vanadate in the tail slag was firstly treated,and then the washing method of the tail slag was optimized. The results show that the actual process scheme can be further optimized by simulation analysis. The total water consumption and evaporation water in vanadium extraction process can be reduced respectively by 7 552 t/a and 7 521 t/a, and the energy consumption of vanadium extraction process can be significantly reduced by the simulation results.
