Evaluation of a dry filter for dust removal under laboratory conditions in comparison to practical use at a laying hen barn.

摘要: The high amount of particulate matter from poultry houses in the exhaust air, especially at different types laying hen barns, is main challenge farmers are faced with concerning emissions. As a possibility for mitigation outgoing dry filter based on principle centrifugal force was investigated under laboratory and field conditions. Aerosol spectrometers were used continuous measurements raw clean gas. Field experiments took place summer winter conditions, so that efficiency climate conditions could be compared measurement values barn continuously collected over 24-h periods. Data showed filter, whereas results differed each size fraction matter. These differences may explained by fact better circumstances correct measuring created, e.g., laminar flow air.
