Energy saving measures and potential analysis of power lithium battery plants
摘要:
根据南京某锂电池厂实际系统及现阶段能耗特征,结合常规工业厂房节能技术,有针对性地提出了结合锂电池厂工艺流程的节能措施。通过TRNSYS模拟和技术经济性分析,确定了全年运行能耗降低情况及节能改造方案的投资回收期。研究结果表明,采用涂布热回收、老化机组热回收、免费供冷技术及高低温冷水机组,全年的节能率为14.6%,动态投资回收期为1.9 a,具有良好的技术经济性。
Abstract:
In this paper, according to the actual system and energy consumption characteristics of a lithium battery plant in Nanjing, combined with the conventional industrial plant energy saving technology, the energy saving measures combined with the craft process of the lithium battery plant are put forward. Through TRNSYS simulation and technical and economic analysis, the reduction of annual operation energy consumption and the investment payback period of energy saving transformation scheme are determined. The results show that the energy saving rate of the whole year is 14.6% and the dynamic investment payback period is 1.9 years by using coating heat recovery, aging unit heat recovery, free cooling technology and high and low temperature chillers, which has good technical and economic performance.
