摘　　要：一些小型间冷开式循环水系统以RO产水、软水或其他低电导率的水源作为补水,使循环水系统中的总硬度维持在较低状态。对此类腐蚀性水质,碱度调节不当会增加循环水系统设备的腐蚀速率,影响设备使用寿命,设备内的锈蚀物沉积还会降低换热效率,不利于循环冷却水系统的稳定运行。采用传统方式投加缓蚀剂难以将腐蚀速率控制在国家标准以内,通过对比测试不同调节剂在此类系统中的实际使用情况,优化运行工艺,大幅度降低了系统的腐蚀速率,保证了系统安全稳定运行。Some small inter-cooled open circulating water systems adopt RO produced water,soft water or other low conductivity sources as make-up water to keep the total hardness in the circulating water system low.For such corrosive water quality,inappropriate alkalinity adjustment will increase the corrosion rate of the circulating water system equipment,affecting its service life.On the other hand,the deposition of rust and corrosion in the equipment will also reduce the efficiency of heat transfer,which is not conducive to the stable operation of the circulating cooling water system.It is difficult for the traditional way of adding corrosion inhibitors to control the corrosion rate at national standards.Through the comparative testing of different regulators in such systems in the actual use,the operation process is optimized,which significantly reduces the corrosion rate of the system and ensures the safe and stable operation of the system.
