摘　　要：流化床内喷雾增湿可以使颗粒在不断的碰撞中发生强烈的传热传质而团聚长大。综述了颗粒物化特性、操作参数及加入团聚促进剂对颗粒团聚的影响,分析了循环流化床烟气脱硫工艺的工艺过程、床内增湿团聚机理以及综合脱除SO2以及超细颗粒物的可行性,指出增湿团聚技术可以有效提高燃煤烟气中超细颗粒物的脱除效率,有很好的应用前景。Fluidized bed spray humidification and strong heat and mass transfer. The present can make particles agglomerate by constant collision research situation of submicron particles humidifying agglomeration is reviewed in this paper which introduces the influence of physicochemical characteristics of particles, operation variables and agglomeration promoter on particles agglomeration, analyzes the technology of CFB flue gas desulfurization,mechanism of humidifying agglomeration and the feasibility of cooperative removal of SO2 and submicron particles.The technology could improve removal efficiency of submicron particles in coal-fired flue gas and may have a good prospect.
