摘　　要：盐酸再生系统吸收塔出口的烟气中含有大量酸性雾滴和粉尘,严重影响尾气排放。为了减少排放,提出利用微型旋流器将酸雾和粉尘进行分离,通过研究旋流器的压降、分离效率以及含液浓度等关键因素,确定符合实际工况的最佳工艺参数。研究结果表明,旋流器分离效率随压降增大先快速增加再逐渐减小,压降和分离效率随进口含液浓度的增大而略微增加。氯化氢和氧化铁高效工作区分别为18~33 m^3·h^(-1)和18~35 m^3·h^(-1),最高分离效率达到92%和89%,烟气净化效果显著。The smoke from the absorption tower in an acid regeneration system contains acid fog and dust,which leads to excessive exhaust emissions. To reduce these emissions,a microcyclone was used to remove the acid fog and dust. The optimal processing parameters suited for actual operating conditions were determined through a study on key factors,such as pressure drop,efficiency,and droplet concentration. The results showed that the separation efficiency increased when the pressure drop increased rapidly at first and then decreased gradually. The pressure drop and separation efficiency increased slightly with an increase in the acid fog concentration. The high efficiency areas of Fe2O3 and HCl were 18 to 33 m3·h-1,and 18 to 35 m3·h-1,respectively,and the corresponding highest separation efficiencies achieved were 92% and 89%. Therefore,the effect of this process on smoke purification was remarkable.
