Chemical and Petroleum Engineering Aims and scope

This work proposes a design of a multi-vortex classifier–separator with coaxially arranged pipes for the fractionation of bulk materials based on silica gel with a boundary grain size equal to 30–40 microns. The article presents a three-dimensional model of the apparatus and its operation principle. The efficiency of a multi-vortex classifier–separator with coaxially arranged pipes at various design and technological parameters was determined. The k–w shear stress transport turbulence model was used in numerical simulations. The efficiency of one and three sequentially connected classifiers–separators was calculated. The use of an inner tube without a conical junction allows the fractionation of bulk materials based on silica gel with a near-mesh grain size equal to 30–40 microns. An engineering method for calculating a multi-vortex classifier–separator was obtained, which predicts the apparatus efficiency depending on the input velocity of the gas flow and the required size of the near-mesh grain.
