Abstract

The invention discloses a high-efficiency atomization desulfurization device which comprises a lime powder loading and storage system, a lime slurry preparation system, a lime slurry transfer system,a lime slurry storage system, a lime slurry injection system, a desulfurization catalyst storage system and a desulfurization catalyst injection system. The outlet of the lime powder loading and storage system is connected with the inlet of the lime slurry preparation system; the outlet of the lime slurry preparation system is connected with the inlet of the lime slurry storage system through thelime slurry transfer system. The outlet of the lime slurry storage system is connected with the inlet of the lime slurry injection system through the lime slurry transfer system; the outlet of the desulfurization catalyst storage system is connected with the inlet of the desulfurization catalyst injection system. In addition, the invention also discloses a high-efficiency atomization desulfurization method. The high-efficiency atomization desulfurization device has simple structure, low input, low cost, low energy consumption, and desulfurization efficiency of more than 95%; and SO3 is almostcompletely removed.

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 ,...
