THE ENVIRONMENTAL BENEFITS OF USING BAG FILTERS IN METALLURGICAL PLANTS IN THE CZECH REPUBLIC
Abstract
This article is focused on possibilities of dedusting equipments to capture particulate matters from the chosen production process of the metallurgical plants in the Czech Republic. It deals with the issue of particulate matter generated during the production of pig iron. The article presents the manufacturing process at main sections of a metallurgical enterprise for the production of pig iron and possible formation of particulate emissions in individual sections. The emissions from sinter plants dominate the overall emissions for most of the pollutants. In 1980s, the sintering bands in Czech metallurgical plants sintering process was dedusted by cyclones. In 1990s the cyclones were replaced by more efficient electrostatic filters that are currently (since 2011) reinforced by the largest baghouse in the entire mill. Subsequently, the metallurgical companies installed bag filters in other section. All of the new technologies include the bag filter, which is recommended as the best available technology by the European Union. The bag filter captures PM2.5 and PM10 dust particles with 99 % efficiency. A bag filter is highly efficient at reducing dust and simultaneous heavy metals emissions in a waste gas stream.
