脱硫吸收塔除雾器塌陷、喷嘴冲刷大梁分析处理（Analysis and treatment of demister collapse and nozzle erosion beam in desulfurization absorption tower） Two thousand and nine point one zero China Kunming 2009 clean and efficient coal-fired power generation technology cooperation network annual meeting 1, October,, Collaboration, Network, Annual, Meeting, of, and, Clean Kunming, China, Efficient, Coal-fired, Power, Generation, Technology Analysis and treatment of demister collapse and nozzle erosion beam in desulfurization absorption tower Liu Datang Anyang power Limited Liability Company, address: Henan Anyang City Huaxiang No. 1 zip code: 455004 Abstract: the desulfurization absorption tower of #9 and 10 units of Anyang power plant found that the fouling of the demister seriously collapsed and caused the damage of other equipment in the absorption tower, which led to the failure of the flue gas The design can meet the design requirements of the discharge humidity, increase the water absorption capacity of the absorption tower, make the flue gas condensate pipe drainage and slurry pressure increase, resulting in clogging of the condensate pipe The clean flue, the partial bypass flue and the front horizontal flue cause corrosion, blockage and leakage, and the desulfurization efficiency is also affected. Outage inspection also found near the beam The part of the nozzle jet faces the beam, and the girder from the brush wear and corrosion seriously affects the safe operation of the desulfurization system directly. The fouling, collapse and spray of demister are discussed in this paper The paper analyzes the erosion of the beam, puts forward some suggestions and solutions to improve the economy and safety of the operation of the desulfurization system. Key words: demister collapse; blockage; flushing; lashing; nozzle; crossbeam; adjustment; treatment 1. The absorption tower slurry nozzle is one of the key equipment in the desulfurization unit The atomization performance has an important influence
