This waste material is normally transported by various air conveying systems from each cleaner in the gin to a final outdoor collection point. Cotton gins then rely on cyclone collectors to remove the waste from the conveying air before discharging the air to the atmosphere. These cyclones need to operate at maximum efficiency to prevent excessive dust emissions which might cause the cotton gin to violate Federal and State air quality regulations. A new long cone cyclone design was tested using full-scale, 34-inch-diameter cyclones and stripper cotton trash material. The new cyclone design was found to be superior to a standard 1D3D design. The long cone cyclone, when compared to the conventional one, reduced particulate emissions by 21.6% and static pressure requirements by as much as 37%. An expansion chamber in the lower cone of the long cone design did not significantly improve its collection performance. Technical Abstract: Two experimental long cone cyclone designs were found to be superior to a standard 1D3D design in an experiment using full-scale cyclones and cotton gin trash from stripper harvested cotton. The long cone cyclones, when compared to the conventional one, reduced particulate emissions by 21.6% and static pressure requirements by as much as 30%. |
