CEMENT KILN DUST PROCESSING SYSTEM AND METHOD

摘要

To provide a method for removing at least one heavy metal from exhaust gas flow.SOLUTION: A method including: a step at which at least one heavy metal is separated from an exhaust gas stream, and a heavy metal-containing stream is formed; a step at which the heavy metal-containing stream is processed with a processing liquid which contains a reagent as a solution; and a step at which at least a part of heavy metal is removed from the heavy metal-containing stream. The processing step includes exposing the heavy metal-containing stream to the processing fluid containing the reagent as a solution. The removing step includes formation of fine particles containing at least one heavy metal, and collection of the fine particles in at least one fine particle collection system.SELECTED DRAWING: Figure 1
