Interpretive Summary: The standard particulate emission control device on cotton gin exhausts is the 2D2D or 1D3D cyclone. These collectors have demonstrated their effectiveness in controlling gin particulate emissions by enabling gins to meet regulatory requirements. However, there is a need to further improve cyclone operational efficiency in order to meet more stringent control requirements. A series of laboratory tests were conducted on 12-inch- diameter experimental cyclone models to find ways of further improving performance. It was determined that the proper design of the inlet to a cyclone could significantly improve its collection performance. Also, alternative cyclone designs were significantly improved in collection efficiency over the standard 2D2D or 1D3D design. These experimental results will be tested using full-size cyclones

Technical Abstract: Experiments were conducted to evaluate the particulate collection performance of several model cyclone designs against the standard 1D3D cyclone. The design of the cyclone inlet and the inlet transition significantly affected cyclone effectiveness. The type of inlet transition to a 1D3D cyclone could affect particulate collection by as much as a factor of 1.37. A 3/4D4D and an alternate 1D3D design, both with 2D2D style inlets, improved particulate collection over the best standard 1D3D by factors of 1.23 and 1.29, respectively. These results will be verified by performance testing of full-size cyclones.
