烧结机湿法脱硫系统设计、运行及维护

中国烧结机烟气脱S工程应用时间较短,国内成熟的烟气脱S技术在燃煤电厂已广泛应用,如湿法、干法、半干法、氨法等,主流技术是湿法脱S。由于烧结机脱S运行故障较多,维护工作量较大,急需总结相关工程设计、运行维护经验。结合已实施的烧结湿法脱S项目,针对烧结厂工况和烟气条件的特点,从烧结机湿法脱S系统的设计优化、运行维护及生产管理方面进行了经验总结,可为今后烧结机湿法烟气脱S工程提供借鉴,为工程设计优化、运行维护等提供参考。

Design,operation and maintenance of wet desulfurization system of sintering machine

In China, the application time of desulfurization project of sintering machine flue gas is relatively short. Mature flue gas desulfurization technology has been widely used in coal-fired power plants, such as wet, dry, semi dry method, ammonia method, the mainstream technology of wet FGD. Due to the large sintering machine desulfurization operation failure, maintenance workload, it needs summing up the design, operation and related engineering need maintenance experience. Combined with the sintering FGD projects have been implemented, according to the characteristics of sintering plant condition and flue gas conditions, from the aspects of sintering machine of wet FGD system design optimization, operation and maintenance and production management experiences were summarized, which can provide reference to the future of sintering machine flue gas desulfurization project, and provide reference for the engineering design optimization, operation and maintenance.
