Item Acesso aberto (Open Access) Determinação experimental da vazão de despoeiramento na descarga de carvão coqueificável(Universidade Federal do Pará, 2021-02-26) CHAVES, Gabriel Guedes; MESQUITA, André Luiz Amarante; http://lattes.cnpq.br/1331279630816662Dust control mechanisms during industrial processes are often carried out using spray nozzle methods or exhaust systems, equipped with bag filters. The following work aims to develop an experimental method to determine the volume of exhaust in different quantities of materials and different heights of material discharge. A test protocol is presented to design exhaust systems for any material, mass flow and drop height, using an experimental method in which it simulates the material drop in order to evaluate experimental dedust flow rates for an industrial ventilation system. A literature review of the current empirical models of exhaustion volume is presented. The methodology is correlated through the concentration of respirable particles measured by the measurement equipment with the exhaust flow data. The results presented are for coal, comparing existing and suggested correlations with experimental data for three different heights of fall. It is hoped, therefore, to support design engineers in the design of industrial exhaust systems, reducing the damage caused by fine particles in workers and in the population that lives near the polluting source.
