摘要
燃煤电厂锅炉在燃烧过程中产生的SO3不仅污染环境,还会严重影响机组的稳定运行。本文分析了碱基喷吹脱除三氧化硫技术的特点、原理、吸附剂选择、喷吹位置和喷射单元。应用实例分析中,采用碱金属盐,通过溶解送至烟道并与烟气充分混合后发生反应脱除SO3,可实现90%以上的脱除率,有效解决了SO3污染问题。
The boilers in coal-fired power plants will produce a certain amount of SO3 during the combustion process,which causes environmental pollution and seriously influence the the stable operation of the machine.The characteristic,principle of SO3 removal by alkaline sorbent injection was analyzed,as well as the sorbent selection,the position of injection and injection unit. In this case,alkali metal salt was dissolved and sent to react with the flue after fully mixing. It was concluded that the SO3 removal rate was higher than 90% and SO3 pollution problem was solved effectively.
