一种新型生石灰消化及除尘装置的研究与应用

Research and optimization of quicklime digestion technology in sintering plant

本文针对烧结厂生石灰消化系统存在的问题及其配套除尘系统的问题进行了分析,研究了一种新型烧结用生石灰消化系统及除尘装置,并在新余钢铁厂360 m^26~#烧结机应用。生产应用表明:使用新型生石灰消化及除尘装置后,烧结利用系数提高了0.018 t·m^(-2)·h^(-1),焦粉消耗降低了0.19 kg·t^(-1),粉尘排放量下降到25 mg·m^(-3),达到了节能减排的目的,改善了配料室区域的工作环境。

The problems of quicklime digestion and dedusting systems in sintering plant were analyzed in this paper. A new quicklime digester and dust removal device were studied and applied in the 360 m^26^# sintering machine of Xinyu iron and steel plant. The results show that the sintering utilization factor increased by 0.018t·m^-2·h^-1, the consumption of coke reduced by 0.19 kg·t^-1 and the dust emission reduced to 25 mg·m^-3 after using the new quicklime digestion and dedusting systems, which achieved the purpose of energy - saving, emission reduction, as well as work environment improving.
