【 摘 要 】

The aim of the work is to improve cyclone and filter dust collectors by increasing the efficiency of fine particle deposition classes PM10, PM2,5 as well as reducing energy and material costs. The analysis of existing methods of cyclonic filtration of industrial dispersed emissions is carried out. The laboratory tests of the cyclone filter, made by modernization of the cyclone CN-11-200, were performed, the aerodynamic characteristics of its operation were found. The calculated determination of the efficiency of suspension deposition from multiphase flow in the separator using a dimensionless Rer criterion is performed, derived from the Navier-Stokes single-phase flow equations of motion and the particle motion equation based on Newton's law. A numerically studied the aerodynamic parameters of the cyclone on the basis of computational fluid dynamics methods. For mathematical modeling of turbulence we used the DES model.
