摘要
石灰石-石膏湿法烟气脱硫系统中,喷淋层是吸收塔内最为核心的部件之一,其设计直接影响到脱硫系统的性能参数和运行可靠性。对于超大直径吸收塔,塔内喷嘴密布,如何保证塔内高的脱硫效率,同时又不会发生浆液喷穿塔壁和支撑梁的问题,是大型吸收塔喷淋层设计的难题之一。文章对超大型直径吸收塔喷淋层设计进行了研究和优化,以便为国内同类型脱硫工程吸收塔的设计提供借鉴及参考作用。
The spray bank is the most important system of absorber in wet limestone-gypsum FGD plant.The design will affect the performance data and operation reliability of FGD.For large-scale absorber,how to ensure the nozzles with high removal efficiency without slurry injecting and wearing absorber and support beam,is critical problem in the design of spray bank.This article introduces the process design principle of spray bank in order to provide reference experience for the similar FGD project in domestic.
