摘　　要：在硫黄设计产能14.75 t/d的Lo-Cat络合铁湿法脱硫装置基础上,串联蓄热式热氧化器对脱硫尾气进行焚烧处理,实践结果表明:Lo-Cat工艺对φ(H_(2)S)6%~7%的低浓度硫化氢酸性气的脱除效果好,装置负荷适应范围宽,脱除硫化氢后的尾气经750℃左右高温焚烧处理后,可有效改善低浓度挥发性有机化合物的环境影响。On the basis of the Lo-Cat complex iron wet desulfurization unit with a designed sulphur capacity of 14.75 t/d,the desulfurization tail gas is incinerated by a series regenerative thermal oxidizer.The practical results show that the Lo-Cat process can effectively remove the acid gas ofφ(H_(2)S)6%~7%with a wide range load adaptation.The tail gas after removing hydrogen sulfide is incinerated at a high temperature of about 750℃,and the impact on the environmental by low concentration volatile organic compounds is effectively improved.
