摘要
2015年投产的河南中原黄金冶炼厂整体搬迁升级改造工程,设计年处理含铜及贵金属原料150万t,分两期实现,采用“造锍捕金”技术回收贵金属。火法冶炼工艺选择了底吹熔炼、旋浮吹炼、回转阳极精炼的新型组合,其中铜锍吹炼采用了旋浮吹炼技术。旋浮吹炼技术的核心设备是一台“旋浮吹炼炉”及“旋浮吹炼喷嘴”,旋浮吹炼炉炉体由中国恩菲设计,其设计反应塔规格为Φ4.5 m×6.2 m,旋浮吹炼工艺包及“旋浮吹炼喷嘴”由祥光铜业提供。河南中原黄金冶炼厂的旋浮吹炼炉是国内首座,采用国内技术、完全自主设计、全部国内制造。经过投产后五年的运行及鉴定看,该炉具有结构合理、布置紧凑、操作方便、维护量小、作业率高等优点,其先进的整体弹性骨架结构和合理的水冷技术,加上相匹配的砖体,完全适应了旋浮吹炼工艺的技术要求,成为一台安全、稳定、高效、长寿运行的吹炼炉,实践证明该旋浮吹炼炉的设计是成功的。
In 2015,the green-field upgrade project for Henan Zhongyuan gold smelter was put into operation.The project is designed for handling 1500000 tpa copper concentrate containing precious metals,and it is scheduled for 2 stages.The project process employs oxygen bottom blowing furnace as smelting,Rotation-Suspension furnace as converting,and rotary anode furnace as refining.Wherein,the Rotation-Suspension furnace with reaction shaft sizeΦ4.5 m×6.2 m named from the use of the Yanggu patented Rotation-Suspension nozzle,is entirely innovative designed by ENFI under Yanggu’s progress package.Rotation-Suspension converting furnace is an innovative design of a metallurgical furnace after comprehensive summary of decades of experience in the design of large metallurgical furnace.Besides this,it is also the first domestic converting furnace using domestic technology,completely independent design,all domestic manufacturing Rotation-Suspension converting furnace,with a reasonable structure,compact layout,easy operation,low maintenance,high rate of operation,etc.Applying advanced overall flexible frame structure and rational water-cooling technology,coupled with matching brick,fully adapted to Rotation-Suspension process,the converting furnace has the technical characteristics of safe,stable and efficient,long life.After 5 years of excellent operation,it can come to the conclusion that the design of Rotation-Suspension is supper successful.
