Semeniuk M. Cleaning gas flows in centrifugal filters

The thesis is dedicated to the development and research of the apparatus of a new construction - a centrifugal filter, which combines two principles of purification: centrifugal separation and multiple filtration through the dynamic dust layer. The results of experimental studies of aerodynamic characteristics and the efficiency of dust collecting for the centrifugal filter had been presented in the paper. On the basis of the energy principle, the calculated dependencies with constant a and n had been obtained according to the data of laboratory-experimental studies and characteristics of materials. Multivariate numerical calculations of flue gas cleaning efficiency from SO2. A three-dimensional model of the centrifugal filter had been created and numerical and analytical research had been carried out. The increase in productivity by 10% without additional energy consumption for grinding had been achieved at the modernization of the aspiration system of cement mills at the enterprise «EUROCEMENT-UKRAINE» (Balakliia city). The passing of solid particles by 2-3 times compared with the analogue had been reduced due to the improvement of centrifugal filter construction in the form of successively connected curvilinear channels with the removal of particles in separate bunkers seally insulated from each other.
