摘　　要：活性石灰回转窑烟气超低排放环保改造项目,采用小苏打粉脱硫工艺。小苏打粉(NaHCO3)在烟气中分解成Na2CO3,因其异常活跃,在烟气管道中会立刻与烟气中的酸性物质发生反应,脱除SO2及其它酸性物质。项目投入运营后,基本实现了SO2的近零排放。The project of environmental protection reconstruction for ultra-low emission of flue gas from active lime rotary kiln adopts the technology of desulfurization with baking soda powder.The baking soda powder(NaHCO3)is decomposed into sodium carbonate(Na2CO3)in flue gas.Because Na2CO3 is very active,it will react with acid substance in flue gas to remove SO2 and other acid substance.After the project was put into operation,the SO2 emission was nearly zero.
