摘要
论述石灰石-石膏湿法脱除烟气中SO2的技术特点、工艺流程,对关键技术参数(空塔气速、液气比、钙硫比、循环浆液质量浓度、循环浆液p H值)、影响系统运行和石膏品质的因素进行了分析。
The technical characteristics and process flow of limestone-gypsum wet process for removal of S02 from flue gas are discussed. The key technical parameters, including empty tower gas velocity, liquid-gas ratio, calcium-sulfur ratio, slurry mass concentration and slurry pH value, as well as factors affecting the operation of the system and the quality of gypsum are analyzed.
