| Summary: | A cyclone separator is an equipment that separates particles contained in a liquid or gas without filters. Dust particles in flue gases can be separated using centrifugal forces and different particle densities so that the exhaust gases must be cleaned before being discharged into the environment. The selection of optimal geometric dimensions and operation parameters of industrial equipment is always a topical issue. In the work, numerical modeling and research of a modified centrifugal cyclone dust collector are carried out. A modified centrifugal cyclone was developed by one of the article's authors at the Institute of Mechanics and Seismic Resistance of Structures of the Academy of Sciences of the Republic of Uzbekistan, which has a high efficiency of at least 98%. The study was carried out in the Comsol Multiphysics 5.6 engineering software package using the Flow Simulation add-on, designed to simulate hydrodynamic processes. The relevance of the chosen research topic was indicated. The standard k-ɛ model is chosen as a turbulence model, which is often used in engineering problems. The computational experiment was carried out at three flow rates in the centrifugal cyclone. Based on the obtained numerical data, it is shown that the efficiency of the modified cyclone is significantly higher than that of the classical cyclone.
