脱硫系统湿烟囱石膏雨成因分析与治理研究

Analysis and Countermeasures on the Cause of Gypsum Rain in Wet Stack of Desulfurization System

目前火力发电厂湿法脱硫后均采用"湿烟囱"的排放方案,但是由此产生的"石膏雨"会带来严重的环境影响和危害,重点介绍了目前湿法烟气脱硫后"石膏雨"的影响因素和定州电厂相关改造治理方案。

At present, all the thermal power plants adopt the discharge scheme of ＂wet stack＂ after wet desulfurization, however, this mode may cause ＂gypsum rain＂ which has brought serious environmental impacts and hazards. The paper focused on the influence factors of ＂gypsum rain＂ after wet flue gas desulfurization and correlative modification and treatment scheme in Dingzhou Power Plant.
