窑尾排风机智能调速控制改造实现方法

The Implementation Method of Transformation of Preheater Exhaust Fan Intelligent Speed Regulation Control

本文涉及水泥行业窑尾排风机的智能调速节能改造,针对窑尾排风机进行变频智能调速改造后,保证窑系统生产环节能够满足正常生产工艺要求,同时可以降窑尾排风机的电耗。介绍了以变频调速为核心手段来实现窑尾排风机出口流量的调节,取代原有通过档板或阀门的开度来调整流量的控制方式,提高烧成工段自动化程度且降低窑尾排风机的运行电耗。

In the cement industry in the energy saving renovation of preheater exhaust fan of intelligent speed regulation for preheater exhaust fan of intelligent frequency conversion speed regulation reform, maintain the normal production of kiln system can satisfy the production process requirement, can drop preheater exhaust fan power consumption at the same time. Introduces the frequency control of motor speed as the core means to realize the preheater exhaust fan outlet flow adjustment, replace the original by damper or valve opening to adjust the flow control mode, improve the burning section of preheater exhaust fan operation of automation and reduce power consumption.
