The authors of the work have developed a methodology that allows, on the basis of calculating the values of sanitary-hygienic and environmental efficiency, as well as the energy-intensive indicator of the processes of collecting dust and cleaning the gas-air stream from dust, to select and design a highly efficient and energy-efficient engineering dust suppression system for a drying drum operated in brick factories

The authors of the work analyzed the successive stages of the process of reducing air pollution in the working area and atmospheric air, built a physical model of the process for reducing air pollution and selected the preferred options for the efficiency of dust suppression technologies in relation to the operating conditions of the drying drum of a brick factory.

The authors (of the research) suggest choosing the most eco- and energy-efficient engineering system in order to purify the air of the dyrer drums dust. The choice should be made on the basis of the analysis and evaluation of the dust properties and determination of the control methods of the dust aerosol stability, which, eventually will ensure its effective destruction as a dispersed system in the air purification process.
