循环水整体优化节电项目的成功应用
|
摘要
齐鲁石化股份有限公司供排水厂针对乙烯水务车间第三循环水场(三循)存在的电耗高实际问题,于2015年开展了循环水整体优化节电改造项目,通过优化循环水系统节能运行模式、更新高效率节能型循环水泵、新增循环水泵和冷却风机变频设备及强化节能管理等一系列技改措施,用电量逐渐下降,节能效果逐步显现,达到了预期既定目标。三循自实施节能优化和自动控制系统改造并正式投入运行以来,工艺指标可控,设备参数正常,循环水泵和冷却风机运转平稳,系统高耗电现状得到明显改善,优化运行11个月共计节约电量545.7×10~4kWh,创效322.5万元,收到了较好的节电效果。
with the increasing requirements of the state for energy conservation and consumption reduction in petrochemical enterprises,the water supply and drainage plant of Qilu petrochemical co.,ltd. of Sinopec is also facing increasing pressure on energy conservation. In view of the actual problem of high power consumption in the third circulating water plant of ethylene water supply workshop(hereinafter referred to as " three circulation", the same as the following), In 2015.through a series of technological renovation measures such as optimizing the energy-saving operation mode of the circulating water system, updating high-efficiency and energy-saving circulating water pumps,adding frequency conversion equipment for circulating water pumps and cooling fans, and strengthening energy-saving management, the electricity consumption gradually decreased, and the energy-saving effect gradually appeared, reaching the expected set target. Since Sanxun implemented the energy-saving optimization and automatic control system transformation and put it into operation, the process indexes are controllable, the equipment parameters are normal,the circulating water pump and cooling fan run smoothly,and the current situation of high power consumption of the system has been significantly improved. After 11 months of energy-saving optimization operation, a total of 5.547 million kW.h of electricity has been saved, and 3.225 million yuan of efficiency has been created, and good energy-saving effects have been achieved.
