The pollution problem of desulfurization waste liquid and sulphur sludge in desulfurization process at home and abroad,A new process for producing concentrated sulphuric acid from the waste liquid of coking desulfurization and slime dry incineration is put forward.Using the process of sulfur foam desulfurization wastewater and common quality and drying,the direct burning of sulfur salt the use of advanced"3 + 2"ⅢⅠ-ⅤⅣⅡ two RPM two suction process,improve the sulphur resource utilization rate,the total conversion rate of SO_2 more than 99. 7%; In the process of production,the wastewater from the process is recycled,and no two pollution is produced.
