Interpretive Summary: Because of changes in the Federal Clean Air Act, cotton gins are having to meet more stringent state and Federal particulate emission requirements. Due to the nature of the cotton ginning industry, it is important that the design of the high-efficiency cyclone be improved, so that it will be retained as the industry's primary particulate collection device. A series of tests using model cyclones has indicated that the particulate collection performance of the industry standard 1D3D high-efficiency cyclone can be improved by a factor of 1.3. Verification of these results by tests of full-size cyclone units will result in cyclone designs that will allow the ginning industry to readily meet current particulate emission regulations.
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.
