水冷器壳程腐蚀防护的仿真与优化
Simulation and Optimization of Corrosion Protection of Water Cooler Shell Side
摘 要
为抑制工业冷却水对水冷器壳程侧的腐蚀,提高水冷器的腐蚀防护效果,采用电化学测试与边界元模拟计算相结合的研究方法,开展了不同温度条件下牺牲阳极保护、硅醛涂层+牺牲阳极联合保护的水冷器的保护效果仿真评价。结果表明:水冷器所需的阴极保护电流密度随着温度的升高而增大,硅醛涂层保护的水冷器所需的阴极保护电流密度显著减小,硅醛涂层+牺牲阳极的保护效果优于牺牲阳极保护,且对水冷器换热效率的影响较小。

Abstract
In order to inhibit the corrosion of industrial cooling water on the shell side of water cooler and improve the corrosion protection effect of water cooler, the simulation evaluation of protection effect of sacrificial anode protection and silicon aldehyde coating + sacrificial anode combined protection under different temperature conditions was carried out by using the combination of electrochemical test and boundary element simulation. The results showed that the cathodic protection current density required for the water cooler increased with the increase of temperature, and the cathodic protection current density required for the water cooler protected by the silicon aldehyde coating decreased significantly. The protection effect of the silicon aldehyde coating + sacrificial anode was better than that of sacrificial anode protection, and had little effect on the heat transfer efficiency of water cooler.
