Abstract
By means of numerical modeling in the program ANSYS Fluent CFX the evaluation of fractional efficiency in a direct-flow cyclone with intermediate dust collector has been carried out. The boundary conditions were as close as possible to the experimental ones. As a gas phase, the authors take the air under normal conditions, as the solid phase – spherical particles of 30 and 80 microns in size. In order to evaluate the adequacy of the calculation model, a laboratory installation of a DCIC with two separate chambers for the selection of collected particles was made. This design allowed estimating the fractional efficiency of both individual chambers of a direct-flow cyclone DCIC and the apparatus as a whole. The results of the experiments carried out on different types of dust (fly ash, cement) showed a good convergence with the design model
