Performance Characteristics of Cyclones in Cotton-Gin Dust Removal

The results of performance testing of four different cyclone designs are included in this paper. The 1D3D, 2D2D, 1D2D and Barrel cyclone designs are typically used to abate particulate matter (PM) emitted by cotton gins. The PM used for testing included three types of cotton gin trash (with and without lint fiber) and fly ash. The performance tests were conducted at different total trash inlet loading rates and at different fine dust inlet loading rates based on the fine dust fractions associated with each trash. The results were used to define the performance characteristics of different cyclone designs. With these characteristics, cotton ginners can utilize different cyclone designs for different processing streams to minimize PM concentrations emitted.
