Description
Technical Field
The utility model belongs to the technical field of the processing technique of converter steelmaking flue gas and specifically relates to a novel converter cubic dust excluding hood.
Background
The secondary and third dust removal of a steel plant is relative to the primary dust removal, the primary dust removal refers to the treatment process of searching, cooling and purifying high-temperature smoke generated in the converter converting process through a flue, and in order to achieve the purposes of saving energy and protecting equipment, a fan for primary dust removal generally runs at a low speed during the tapping and slag splashing time of the converter, namely the non-converting time, so that the primary dust removal cannot play a role in dust removal. Although less smoke and dust are generated in the blowing time of the converter, some smoke and dust are generated in the blowing process of the converter, and meanwhile, in order to recover coal gas, a certain positive pressure difference is needed at a furnace mouth, namely, all smoke and dust cannot be absorbed by primary dust removal, and certain smoke and dust are generated in the processes of escaping certain smoke and dust out and tapping in the blowing process, so secondary dust removal equipment and tertiary dust removal equipment are provided. The two-time dust removal and the three-time dust removal are simpler gravity dust removal and cloth bag dust removal. The air inlet of the dust remover is generally arranged around the first flue and is connected to the dust remover through a pipeline. The secondary and tertiary dust removal is an environmental protection measure for making up the deficiency of the primary dust removal.
