摘　　要：采用湿法脱硫的燃煤电厂,吸收塔pH值是主要控制指标,pH值过高会使石膏元法脱除,吸收塔密度持续升高,引起环保停机。国能重庆万州电力有限责任公司吸收塔高pH值运行和pH值过高危害及处理,为其他电厂吸收塔的运行提供了运行经验。The pH value of the absorption tower is the main control index for coal-fired power plants with wet desulfurization.Exorbitant pH value will make gypsum unable to be removed,the density of the absorption tower will continue to rise,resulting in environmental protection shutdown.The high pH value operation of absorption tower and the hazards and treatment of high pH value of absorption tower of Chongqing Wanzhou Electric power Co.,Ltd.provides experience for the operation of absorption tower of other power plants.

关 键 词：吸收塔 PH值 湿法脱硫
