摘要
作为过程工业中高能耗辅助系统的代表,循环水系统表现出用户多、系统复杂、能耗高等特性,决定了工业循环冷却水的研究重点集中在系统节能和降低总体水量这两个方面。本文提出了工业循环冷却水系统的多尺度整体协同优化策略,从系统与设备层面进行循环冷却水系统的多尺度优化,以降低整体水耗和能耗。以国内某炼油厂的单个循环水系统优化为例,节能节水协同优化与改造前相比,系统节水25.6%,考虑长周期运行情况,节水23.6%,系统节能25.6%。
As a representative of high energy consumption auxiliary systems in the process industry,the circulating water system exhibits characteristics such as multiple users,complex system,and high energy consumption,which determines that the research focus of industrial circulating cooling water is on system energy conservation and reducing overall water volume.This thesis proposes a multi-scale overall collaborative optimization strategy for industrial circulating cooling water systems,multi scale optimization of the circulating cooling water system at the system and equipment levels to reduce overall water and energy consumption.Taking the optimization of a single circulating water system in a domestic refinery as an example,the energy and water-saving synergistic optimization save 25.6%of water in the system compared with that before the transformation,and 23.6%of water considering the long cycle operation,and 25.6%of energy-saving in the system.
