Summary: | The invention discloses a finished product dedusting method and device for direct reduction iron, and the method comprises the following steps: mixing a certain amount of auxiliary dust into to-be-dedusted flue gas of a finished product storage and transportation system, wherein the auxiliary dust is used for diluting the concentration of pure iron powder in the to-be-dedusted flue gas to form mixed flue gas suitable for treatment of a dry dust remover; and the mixed flue gas is subjected to dry-type filtering dust removal treatment through the dry dust remover. According to the dust removal method, a certain amount of auxiliary dust is mixed into the to-be-dedusted flue gas of the finished product storage and transportation system, so that the concentration of pure iron powder in the to-be-dedusted flue gas is diluted, combustion of dust with active chemical properties in the dust remover can be inhibited or weakened, and the dust can adapt to filtration treatment of a dry dust remover. Due to the fact that |
