Abstract:ation method,a flue gas purification system based on the process of "quench+dry deacidification+acti⁃vated carbon adsorption+bag dust removal" was designed. The effects of cooling water consumption,hy⁃drated lime consumption and activated carbon consumption on the treatment were investigated. The re⁃sults shows that when the cooling water consumption is 0.9 t/h,the calcium acid ratio is 1.4 and thedosage of activated carbon is 3 kg/h,the removal rates of acid gas and dioxin reach 75.32% and95.42%,respectively. The average emission concentration of dioxin is 0.023 ng-TEQ/Nm3. The totaloperating cost is about 137.35 yuan/h. Close-
