摘要
腐蚀作为循环冷却水系统面临的三大问题之一,对其进行实时、准确的监测,有助于及时发现和控制生产中的腐蚀问题。在分析已有腐蚀速率监测技术的基础上,结合换热器材质、水质、腐蚀控制的实际情况和控制效果,模拟管壳式换热器运行过程中冷却水的流动与传质特点,构建了循环冷却水动态模拟综合评价系统。结合最小二乘支持向量机算法原理,以腐蚀速率为目标量,建立了基于水质参数预测腐蚀速率的模型,为阻垢缓蚀效果的评价提供了可靠的腐蚀特性数据。
Corrosion is one of the three major problems faced by the circulating cooling water system,and its real-time and accurate monitoring is helpful to timely detect and control corrosion problems in production.Based on the analysis of the existing monitoring technology of the corrosion rate,and combined with the actual situation and control effect of heat exchanger materials,water quality and corrosion control,the flow and mass transfer characteristics of cooling water during the operation of shell-and-tube heat exchangers are simulated,and a dynamic simulation and comprehensive evaluation system of circulating cooling water is constructed.Combined with the principle of the least square support vector machine algorithm,a model for predicting the corrosion rate based on water quality parameters is established with the corrosion rate as the target quantity,which provides the reliable data of corrosion properties for the evaluation of scale and corrosion inhibition effects.
