火电厂烟气脱硫装置吸收塔倒装工艺

Upside-down construction methodology of flue gas desulfurization absorption tower for coal-fired power plants

吸收塔是火电厂烟气脱硫装置中的关键设备,以铜陵电厂2×1 000MW机组烟气脱硫装置吸收塔安装为例,介绍了吸收塔倒装工艺及其特点。由于倒装法在降低费用、缩短工期、减少高空作业量、不受场地限制等方面具有显著的优点,因而在吸收塔的施工技术中被广泛采用。

Absorption tower is served as critical equipment for desulfurizing facilities in power plant.The process and characteristics of upside-down constraction methodlogy of FGD system in 1000MW units in Tonyling Power are introduced.With its distinctive advantages,such as cost-effective,time-saving,minimizing of work at height,free from limited space,upside-down construction methodology is widely adopted in the construction of absorption tower.
