济南钢铁股份有限公司炼钢厂210 t转炉采用干法(LT法)烟气净化工艺,轴流风机是该系统的重要设备,主要作用是为转炉烟气提供动力来源。详细介绍了轴流风机风量控制的形式及原理,分析了生产中风机风量理论计算值与转炉实际产生烟气量相差较大的原因,并提出了解决办法,通过对风机风量控制模型参数的优化,降低了风机的能耗,避免了配水量失真,粉尘湿度大等问题,为干法除尘系统的稳定运行打下了坚实的基础。
Jinan Iron & Steel Co., Ltd. 210 t converter steel mill using dry (LT France) flue gas purification process, the axial fan is an important equipment of the system, the main role is to provide a source of power for the converter flue gas. The paper introduces in detail the form and principle of axial flow fan air volume control, analyzes the reasons why the calculated theoretical value of fan air volume in production is different from the actual flue gas volume generated in converter, and proposes the solution. By optimizing the parameters of the fan air volume control model, , Which reduces the energy consumption of the fan, avoids the problems of water distribution distortion and dust humidity, and lays a solid foundation for the stable operation of the dry dust removal system.
