Description

technical field [0001] The invention relates to the field of environmental protection, in particular to the desulfurization of a cement production line, in particular to a high-efficiency atomization desulfurization device; in addition, the invention also relates to a high-efficiency atomization desulfurization method. Background technique [0002] 1. The source and form of sulfur in the cement production process [0003] There are two main sources of sulfur in the cement production process, one is from raw materials, and the other is from fuel. The sulfur contained in raw meal is divided into organic sulfur, sulfide and sulfate. [0004] Table 1: Sulfur Analysis of Raw Materials [0005] [0006] Organic sulfur is an organic compound of sulfur, and the sulfide is mainly FeS 2 And a small amount of PbS, ZnS, sulfate mainly CaSO 4 、Na 2 SO 4 、K 2 SO 4 . In the preheater system, when the material temperature is less than 200°C, organic sulfur is oxidized to SO 2 ,...
