氯离子对火电厂湿法烟气脱硫系统的影响及处理技术现状

Effect of chlorine ion for FGD system in power plant and actual state of anticloration technology

火电厂湿法烟气脱硫系统氯离子来源于燃煤、脱硫剂及工艺水。氯离子具有侵蚀性,会对系统材料产生腐蚀,而且会降低脱硫效率及石膏品质。通过沉淀、膜处理及蒸发技术等方法可以对氯离子进行去除,但是存在一定的技术难度。

The chloride ion for FGD system was from coal,desulfurization agent and process water. It was corrosive,the material of system was corroded,but also desulfurization efficiency and the quality of gypsum was reduced. By precipitation,membrace treatment,evaporation and other methods the chloride ion was removed,but there was a certain degree of technical difficulty.
