Kozii I. Scientific foundations of the system approach to reducing the man-made load from industrial emissions on the environment

The dissertation is devoted to solving the scientific problem of reducing the artificial load on the environment from industrial emissions that contain finely dispersed suspended substances. These emissions have a complex negative impact on all-natural components of the environment and disrupt its ecological balance. Work has developed the scientific and methodological foundations for a systematic approach to reducing the impact of artificial emissions from industrial productions containing finely dispersed suspended substances, specifically PM2.5. Carried out the substantiation of developing a mathematical model of the spread of pollutants, the result of a methodology for selecting environmental protection equipment, and the study of highly efficient constructions of dust cleaning equipment. To forecast and prevent the consequences of technogenic load from dust emissions, an algorithm and software implementation of a mathematical model for calculating the distribution of PM2.5 in the surface layer of the atmosphere was developed. Created a web application for calculating the spread of pollutants, which can be used in monitoring systems to assess and control the artificial impact of industrial enterprises on the surrounding natural environment and to inform the public at various levels. Developed methods for selecting dust and gas cleaning equipment using graph theory and the technique of sequential hierarchical clustering. The mechanism for choosing dust and gas cleaning equipment using the online service of electronic spreadsheets based on comparing parameters of three databases: characteristics of pollutants, technological conditions of the environment, and parameters of dust and gas cleaning equipment, was implemented in software. Based on laboratory studies, designs of devices with a regular pulsation nozzle (nozzle and ejection type) are proposed, which ensure the creation of organized vortex zones in the working area of the device and have a wide range of stable operations. Carried out a study and mathematical description of PM2.5 deposition mechanisms, which allows for designing devices for capturing fine dust. Confirmed the practical significance of the work by the acts of introducing into the production process highly efficient designs of devices and methods of reasoned selection of effective environmental protection equipment, forecasting and calculation of the pollution zone of the surface layer of the atmosphere, as well as the introduction of research results into the educational process.
