湿法脱硫吸收塔在线监测系统常见问题及解决办法

Common problems in on-line monitoring system of wet desulphurization absorber and its solutions

在线监测装置是运行人员的"眼睛",能否正常运行,对整套脱硫系统的可靠、经济、甚至安全运行均有十分重要的影响。脱硫系统所属的关键在线监测装置包括压降测量装置、吸收塔浆液密度和液位测量装置、吸收塔浆液pH值测量装置,堵塞是三者所存在的共性问题,后两者还存在其他方面的常见问题,分析了某厂湿法脱硫吸收塔在线监测系统产生上述常见问题的原因,提出了相应的解决办法。

On-line monitoring device is the eye of operating personnel,it has important influence on reliable,economic and safe operation of flue gas desulfurization system.The key on-line monitoring device of flue gas desulfurization system includes the measuring device of pressure drop,slurry density,the liquid level and pH value in the absorbing tower.Blockage is the coexistent problem.There are some common problems of later two factor.The common problems in on-line monitoring system of wet desulfurization absorber in a thermal power plant are analyzed and relevant solutions are put forward.
