摘要
针对目前国内大多数炼油企业循环水冷却塔均按电动风机进行设计,普遍存在回水扬程偏大的现象。结合中海石油宁波大榭/舟山石化有限公司二套循环水冷却风机节能改造的应用实例,评价了水动冷却风机的节能效果,并分析了其在炼油企业推广的意义。
At present,the electric air machines are used in circulating water cooling tower in many refinery plants,where the backwater lift is generally high.Combining the energy-saving technical example about CNOOC Ningbo Daxie/Zhoushan Petrochemical LTD＇s second reconstruction of cooling air machine,the energy-saving effect of cooling water machine was evaluated,and the developing significance in refinery plants was also analyzed.
