基于 Comsol Multiphysics 的金属储罐阴极保护方案的优化
Optimization of Cathodic Protection Plan for Metal Storage Tank with Comsol Multiphysics
摘要
Abstract
The mathematical model of cathodic protection potential distribution with impressed current on the exterior of metal storage tank bottom is established and calculated by using Comsol multiphysics software.The effects of the numbers and layout of cathodic confluence points depth of auxiliary anode,soil resistivity,and the influence of polarization characteristic on protection potential distribution of tank bottom were studied.The results showed that,with other conditions unchanged,the way of setting confluence points on the center of tank bottom and more points confluence would produce better results of cathodic protection.But due to potential drop of tank bottom with little difference,and considering economic feasibility factors. Single-point confluence at the edges was proposed.Moreover,the smaller the soil resistivity was,the deeper the depth of auxiliary anode was.The tank bottom is not easy to be corroded and polarized.It is better for cathodic protection effect of tank bottom.关键词
