摘　　要：介绍了立式阳极保护浓硫酸冷却器阴极布置特征,阐述了阴极尺寸、位置及阴极间距等参数对阳极保护电位分布的影响规律。对比现有阴极布置方式,立式阳极保护浓硫酸冷却器阴极密封结构简单,便于制造运输,易于安装拆卸。该布置方式在满足阳极保护效果的同时,能够有效减小设备在现场的占地空间。Cathode arrangement characteristics of vertical anodic protection cooler for concentrated sulphuric acid are introduced,effects of anode protection potential distribution on cathode size and cathode position and cathode spacing are described. By comparing current cathode arrangement,cathode seal is simple for vertical structure,convenient for manufacturing and transportation,and easy for installation and disassembly. The arrangement not only satisfied anodic protection effect,but also effectively reduced floor space occupied by equipment.
