氨基酸联产中的分布式供能技术应用探索

Application of Distributed Energy Supply Technology in Co-production of Amino Acids

分布式供能是指将供能系统以小规模和分散式的方式布置在用户附近,同时输出电、热、冷等多种能源,具有能源利用率高、规模小、灵活性强等特点,但该技术在工业生产中几乎没有应用。“有机酸-氨基酸”的生产拥有丰富的余热资源,开展余热回收研究,以期实现节能减排和行业的可持续发展、提高产品生产技术水平。本研究利用分布式供能的系统基本原理,以热/电和冷(热)/热水/电/蒸汽等不同方式对热能的综合利用率进行应用探索,在工业产业层次,实现分布式供能,结果表明,全工况条件下冷/热/电/蒸汽多联供系统的能量利用效率达95%以上,显著高于单纯的热/电输出,可用于氨基酸企业工业生产中余热资源循环综合高效利用,有效提升资源循环综合利用率,对工业产业中热能回收应用具备指导意义。

Distributed energy supply is the energy supply system,which is arranged near the users in a small-scale and decentralized manner,while outputting multiple energy sources such as electricity,heat,and cooling.This technology has almost no application in industrial production.The production of“organic acid-amino acid”possesses redundant heat resources,and the recovery research on redundant heat is important for bringing about the energy conservation,emission reduction and sustainable development,which will improv the production technology.Our research used the basic principles of distributed energy supply systems to explore the comprehensive utilization of thermal energy in different ways.At the industrial industry level,distributed energy supply is realized.The results show that the energy utilization efficiency of the cold-heat-electricity-steam multi-supply system is above 95%,which could effectively improve the comprehensive utilization rate of resource circulation and has guiding significance for the application of heat energy recovery in industries.It is significantly higher than pure heat/electricity output,which can be used for comprehensive and efficient utilization of waste heat resources in the industrial production of amino acid enterprises.
