Análise e proposta de readequação num sistema de despoeiramento de um britador de uma siderúrgica

Abstract

In the present work, an analysis was performed on a dedusting system of a crusher that performs less than expected. This system is installed in the company Maringá Ferro- Liga S.A., located in the city of Itapeva-SP. In this analysis, points were identified in the dedusting system where there are conservation problems as well as poorly dimensioned components. Using an anemometer, velocity measurements were performed on the pipelines to verify if they were within the recommended ranges. In addition, load loss values were calculated and compared before and after the proposed adjustments in this system, using recommendations to minimize the load losses in pipelines, captors, and accessories. Finally, the minimum drive power required for the system was calculated. In addition, the maximum amount of dust collected by the system was also estimated. For load loss calculations, tabulated load loss coefficients of the accessories and captors, pipe velocity measurements (as well as recommended values), pipe friction factor, density and dynamic viscosity of air were used. Based on this analysis, it was possible to propose improvements in the dedusting system, by means of a more adequate dimensioning of its components, thus verifying the possibility of an increase in the system efficiency.
