Abstract

Background & objective: Industrial ventilation systems and dust collectors are effective solutions to reduce particulate emissions in the workplace and environmental in mineral processes. In this study, LOCAL EXHAUST VENTILATION System and dust collectors for control of emitted silica, coke, SILICON CARBIDE dusts from crushing unit was designed and evaluated.Methods: LOCAL EXHAUST VENTILATION system based on standards and guides was designed and implemented after field study of the processes and sources of air pollutants. A set comprised of the four parallel CYCLONEs (Stairmand model) and a new design of the SCRUBBER had been used for dust control. After set-up of systems, its effectiveness in reducing the exposure of workers in the workshops and dust collecting were assessed.Results: Test results were significant differences between the concentration of particles in both on and off the ventilation system revealed (P<0.05). The system has been implemented as means of personal exposure to pollutants and environmental emissions were reduced 93.01% and 64.64%, respectively. Also, alone and integrated collection efficiency of CYCLONE and SCRUBBER, were 94.2%, 59.05% and 97.4%, respectively. The results show good agreement with the values of the parameters ventilation system was designed.Conclusion: Implementation of integrated dust collectors is a good option in industries that have the financial and technical constraints to improve change processes and devices. This method with attainment to health and environmental standards not only can be resolve of the pollution problems, but also will be economically justified of such projects with reduction of depreciation expense and dust recycling.
