摘　　要：针对现有石灰石-石膏烟气脱硫法在运行实践中存在的问题,提出改进的工艺流程,在除尘器前设置半干预调质装置,清除SO3和部分粉尘,实现二级脱硫和三级除尘,具有消除强腐蚀、零废水、节能节水和减少粉尘排放等优越性,可提高系统可用率,并降低投资和运行成本。An improved technological process has been put forward against the existing problems in the practice of present desulfurization way of the flue-gas with limestone ＆ gypsum, i.e. a semi-dry preconditioning device is set in front of the precipitator for removing S03 and partial dust so as to realize twostage desulfurization and three-stage dust precipitation. The improved technology has some advantages such as removing strong corrosive matter, zero waste water, saving energy ＆ water and reducing dust emission, which will increase the availability of the system and reduce the cost of both investment and operation.
