风机变频调速技术在水泥企业节能技改项目中的应用

Application of Multi-fan Frequency Speed Converter in Energy Conservation Projects of Cement Plant

水泥工业是耗能大户,其中风机耗电在总耗电量中占很大比重,节能空间很大,对风机采用传统的液力耦合器直联带动加上入口风门调节的运行方式进行改造势在必行,技改实践表明,风机节能的最佳途径是采用变频器调速技术,节能效果尤为明显。

In cement industry,there exists large energy consumption and fan power consumption accounts for large proportions in total power consumption.The reform of operation mode of fan,using hydraulic coupling driving with air entrance adjustment,is imperative.Technical improvement practice has proved that the best way of fan energy conservation is based on frequency speed control and by this way its energy saving is especially obvious.
