К оценке параметров дисперсного состава частиц твердых ингредиентов в выделениях электросталеплавильного цеха
Аннотация
Дата поступления статьи: 11.05.2024Ferrous metallurgy enterprises annually emit into the atmosphere a significant amount of highly dispersed dust with a particle size of 10 microns or less. The article presents the results of a study performed to determine the dispersed composition of aerosols of solid ingredients in the secretions of an electric steelmaking workshop. Based on the results of a comprehensive optical analysis, the fractional composition, average median values of equivalent dust particle sizes were determined and integral dependences of the distribution density over equivalent sizes (diameters) D for the ingredients accepted for the study were obtained. Mathematical processing of the research results made it possible to obtain regression dependences of the distribution density D as a function of equivalent dust particle sizes. Based on the conducted research, a conclusion was made about the possibility of using inertial type dust collectors in dedusting systems in order to increase the environmental safety of the steelmaking shop.
