Reducing of industrial atmospheric emissions using electrocyclone

Abstract


The article is focused on capturing process-related dust at industrial enterprises (in chemical, metallurgical and energy industries). An electrocyclone can be recommended for the purification of gases emitted into the atmosphere from particulates, such as sodium percarbonate (efficiency 97.5%–99.9%), iron-vanadium concentrate (98.0% - 99.9%), fly ash (99.0%–99.9%). However, the fumes from copper-smelting furnaces cannot be purified with high efficiency (less than 50–60%) because of their properties. Using electrocyclone will reduce the amount of aerosol emissions, and in some cases, let the emission reach the values set by standards.
