水泥行业电机节能发展现状和未来趋势

皖南电机导读:随着规模化基础设施的建设和社会经济的飞速发展,大、中型水泥厂的建设日趋完善,随之而来的节能减排任务相当繁重。在水泥厂用电中,中小型电机占据主导地位,每年所消耗的电能占整个水泥厂电能损耗的一半以上。为了进一步落实国家节能减排政策,实现节能减排的指标,中小型电机的节能是水泥行业所面临的一大课题,也是水泥行业发展的新机遇。

某水泥厂电机节能改造之前现场

▲皖南电机对某水泥厂电机节能改造现场。 

水泥厂无论大小装备都采用的是电机拖动,其中90%是交流异步电机,而且约50%是高压电机,这其中约70%拖动的是风机等类负载,而且这类负载有很大一部分需要调速。目前在传统的水泥厂中,应用最广泛的调节风量的方式是利用电动执行机构来调节挡风板,通过调节挡风板的开度来调节所需风量。

3、结语

推广变频调速等先进电机调速技术,改善电机系统调节方式,逐步淘汰闸板、阀门等机械节流调节方式,重点对传统水泥厂电动机进行系统改造,选择合适的调速方式;合理选配电动机,使电机运行在最佳效率状态;新建或改扩建水泥厂设计时要认真核算,力争做到电机功率与负载的最佳匹配,逐步消除或减少“大马拉小车”现象;设计选型时优先采用高效节能电动机拖动负载,从根本上真正实现电机的节能。
