摘　　要：金川集团公司低浓度SO_2烟气成分复杂,烟气浓度、气量、温度等工况条件差异较大。在吸收治理过程中生产的稀酸、亚硫酸钠等物质对系统设备、设施、厂房等造成了严重地腐蚀破坏。装置运行存在多处安全隐患,运行成本居高不下。通过研究相关腐蚀机理,针对性的采取相关防腐措施,有效降低系统腐蚀状况,提高系统运行稳定性。Composition of low concentrations SO2flue gas is complex.Flue gas concentration,gas flow,temperature and other working conditions varied greatly.During absorption and treatment,the produced dilute acid,sodium sulfite and other substances serious corroded the system equipment,facilities and work shops,factories.There are many potential hazards in the operation of the plant,causing operating costs.By studying the relevant corrosion mechanism and taking the relevant anticorrosion measures,system corrosion has been effectively reduced and the system operating stability was improved.
