摘　　要：机械真空泵系统在钢水精炼领域已逐渐替代蒸气真空泵系统,合理、高效的除尘系统是保证机械真空泵系统正常运行的必要措施。本文介绍了机械真空泵除尘系统的设计和工作原理,以及除尘系统常见的问题和产生原因。结合相关工程实践经验,对除尘系统进行了优化改进,包括双级气体冷却系统、自动脉冲吹扫系统、自动卸灰系统、废气监控与报警系统。优化改进后的除尘系统在某新建电炉炼钢厂的RH真空精炼炉工程上已连续运行一年多,有效保护了机械真空泵的正常运行,满足了RH真空精炼炉的生产工艺要求。Mechanical vacuum pump system has gradually replaced the steam vacuum pump system in the field of steel refining,and a reasonable and efficient dust removal system is a necessary measure to ensure the normal operation of the mechanical vacuum pump system.This paper introduces the design and working principle of mechanical vacuum pump dust removal system,and analyzes the common problems and causes of dust removal system.Combined with the relevant engineering practical experience,the dust removal system is optimized and improved,including two-stage gas cooling system,automatic pulse purge system,automatic dust transferring system,and waste gas monitoring and alarm system.The optimized and improved dust removal system has been continuously operated in the RH vacuum refining furnace project of a new electric furnace steel-making plant for more than one year,effectively protecting the operation of mechanical vacuum pump and meeting the production process requirements for RH vacuum refining furnace.
