摘要
针对火电厂循环冷却水系统普遍存在的管理粗放问题,围绕循环水系统的控制目标,结合循环水的水质特性和运行要求,研发了一套循环冷却水智慧监控系统.该系统由在线仪表、信息传输、控制系统和显示界面4个部分组成,可实现循环水水质的全面、实时、准确监测,以及补水、排污和加药的自动控制,将阻垢剂浓度的变化幅度控制在±1mg·L-1以内,避免因水质波动造成不必要的排污,同时还可减少人工工作量,节约水资源,提升循环水的综合管理水平.
Abstract
In response to the widespread problem of rough management in circulating cooling water systems in thermal power plants,a smart monitoring system for circulating water was developed,focusing on the control ob-jectives of the circulating water system,the water quality characteristics,and operational requirements.The sys-tem consists of four components:online instruments,information transmission,control systems,and display in-terfaces.It can achieve comprehensive,real-time,and accurate monitoring of circulating water quality,as well as automatic control of water replenishment,sewage discharge,and chemical dosing.The concentration variation of the scale inhibitor is controlled within±1 mg·L-1,avoiding unnecessary sewage discharge due to water quality fluctuations,reducing manual labor,conserving water resources,and enhancing the overall management of circu-lating water.
