摘　　要：介绍了1套1200 t/d硫黄掺烧硫酸亚铁制酸装置改造为硫黄制酸装置的改造思路及实施过程。改造利旧风机、转化、干吸、低温余热回收、尾吸等工序,新建熔硫、焚硫工序和发电系统。将高、中位余热回收蒸汽参数从3.82 MPa、450℃提升到5.3 MPa、490℃,同时配套相应参数的背压汽轮机驱动风机和背压余热发电。改造后产汽率1.65 t/t,系统总转化率99.86%,排放尾气ρ(SO_(2))≤10 mg/m^(3),硫酸雾质量浓度小于或等于5 mg/m^(3)。The renovation ideas and implementation process of converting a 1200 t/d sulphur co fired ferrous sulfate sulphuric acid plant into a sulphur-burning sulphuric acid phant are introduced.Revamp the processes of utilizing old fans,conversion,dry and absorption,low-temperature waste heat recovery,tail absorption,etc.,and build new sulphur melting and sulphur burning process and power generation systems.Raise the steam parameters for high and medium waste heat recovery from 3.82 MPa and 450℃to 5.3 MPa and 490℃,while matching the corresponding parameters with back pressure turbine driven fans and back pressure waste heat power generation.After the transformation,the steam production rate is 1.65 t/t,the total conversion rate of the system is 99.86%,the exhaust gasρ(SO_(2))is less than or equal to 10 mg/m^(3),and the mass concentration of sulphuric acid mist is less than or equal to 5 mg/m^(3).
