介绍了超重力机结构和工作原理。浙江巨化股份有限公司硫酸厂2套制酸装置的尾气脱硫系统原采用泡沫塔—复喷复挡装置两级氨法脱硫工艺,技术改造后采用泡沫塔—超重力机两级氨法脱硫工二艺。改造后72h性能考核表明,新脱硫系统排放尾气ρ（SO2）最高429mg/m^3、最低74mg/m^3,ρ（H2SO4）最高31.9mg/m^3、最低8.5mg/m^3,ρ（NH3）最高27.9mg/m^3、最低11.7mg/m^3。技术改造后硫酸厂每年可节省SO2排污费约28.35万元,增产亚硫酸铵/亚硫酸氢铵产品产值约71.5万元/a,经济效益和环境效益可观。

The structure and working principle of high-gravity rotating packed bed are described.Zhejiang Juhua Co.＇s two sulphuric acid plants originally used two-stage ammonia desulphurization process with foam column and multi spray and impact device for tail-gas desulphurization.After revamping,a two-stage ammonia desulphurization process with foam column and high-gravity rotating packed bed is used.The 72 h performance test showed that,the gases emitting from new systems contained 74-429 mg/m^3 SO2,8.5-31.9 mg/m^3 H2SO4 and 11.7-27.9 mg/m^3 NH3.The plants can save about 283 500 yuan/a on SO2 emissions cost and increase about 715 000 yuan/a of ammonium sulphate/ammonium bisulphate product value.Economic and environmental benefits are considerable.
