摘要
介绍了商洛炼锌厂109 m2流态化炉焙烧制酸系统的设计工艺、主要设备及生产运行实践情况。该系统开车一次成功,生产经济技术指标都达到设计值,制酸转化率稳定在99.7%,吸收率超过99.96%,尾气达标排放,且安全连续运行395 d。然后停车检修28 d,对部分工艺设备问题进行改进处理,第二次开车一次成功,生产运行8个月未出现重大问题。
The equipment,technology and improving produce instance are introduced about the system producing sulfuric acid on 109 m2 flowing roasting furnace in zinc smelting company of Shangluo.The system is successful at the first carrying,and it has produced for 395 days continually.The mainly economy producing technological index reached the designed number,and the transform rate of producing sulfuric acid is 99.7% stablily.The absorbed rate exceeded 99.96%,and the trail gas was attained standard.After the produce was finished,the system has been checked and repaired for 28 days,and then a part of technical equipment was improved.The produce is successful at the second carrying.The big serious problem isn＇t appeared after the system has been carried for 5 months.
