Proposição e avaliação de medidas de controle de material particulado em um processo de eletrofusão

Abstract

The processing of solid materials generates emission and suspension of particulate matter - for this reason industries are making major investments in prevention and minimization of emissions, returning those losses into profits by reducing their losses, using environmental protection as a marketing tool, increasing the company's competitiveness in the market. The motivation of this project right comes from the need to mitigating the particulate emissions of an industry that uses the electrofusion process in its production system because there is escape of particulate matter during the process. The main objective of the project consists in analyzing the efficiency of the exhaustion system to guide improvement propositions in it. Four representative sampling points were, samples were collected three times a day during 5 days. Chemical and physical characterization were made by using x-ray fluorescence and with light scattering technique with the Malvern equipment, respectively. After that, the particle size distribution curves were traced so the cyclone cut diameter could be determined. In order too evaluate the exhaustion system it was calculated cyclone efficiency by mass balance; by using the RRB parameters adjusted by linear and nonlinear model adjustment using the results of particle size analysis. The conclusion was that it is necessary to improve the cyclone in order to improve the exhaustion system efficiency reducing the loss and emission of particulate matter. The analyzes guided the resizing of the cyclone.
