Steelmaking primary flue gas dust removal, atomization and dehydration composite device

A steelmaking primary flue gas dedusting, atomizing and dewatering composite device belongs to the technical field of steelmaking primary flue gas dedusting and comprises a first primary flue gas pipeline (1), a dewaterer (2), a second primary flue gas pipeline (3) and an atomizing spray gun (4). Wherein the first primary flue gas pipeline (1), the dehydrator (2), the second primary flue gas pipeline (3) and the atomizing spray gun (4) are sequentially connected by welding. The device is installed in the technological process of the dry electric precipitation technology of the primary flue gasdust removal technology of the converter, the dust emission concentration of the diffusion chimney can be reduced after the device passes through, and the national environmental protection requirement is met. The method has the advantages that the technical problem that dust emission of the diffusion chimney exceeds the standard and seriously pollutes the environment in the initial stage of steelmaking oxygen blowing is
