According to the actual situation of cement kiln, the traditional limestone - gypsum desulfurization process was improved.adding turbulence ring, dehydrator and rectifier equipment developed a set of high desulfurization efficiency, export without droplets, and higher quality gypsum wet desulphurization technology, has been successfully applied in several cement kiln, including the desulfurization system after processing,As a result, the export emission concentration can be accurately controlled within 35mg/Nm³, and the desulfurization efficiency can reach more than 98%. The obtained by-product gypsum has excellent quality, and the moisture content is within 15%. For the export fog drops, its emission is less than 50mg /Nm³, and the technical indexes are in the leading level in China.
