Sustainable development of the country includes a balance between economic growth, social welfare and environmental safety. This means managing all aspects of life so as to ensure the well-being of people and not harm the environment. This is important so that future generations can live in safety. The quality of atmospheric air is of particular importance, as it has a direct impact on people's health. Cement industry is one of the first positions on the scale of emissions of harmful substances, including carbon dioxide (CO₂). In its structure, dust emissions from cement plants are considered mainly as aerodisperse systems. In these systems, the dispersed phase consists of solid particles (dust) or fine droplets, while the dispersed phase is a gas-air mixture This gas-air mixture may contain a variety of contaminants, both organic and inorganic. Predicting and regulating air quality in areas adjacent to cement plants can be achieved by modeling the spread of cement dust. This simulation allows to determine dust concentrations in the air at different distances from the source of emissions and helps to develop effective measures to reduce the man-made load on the environment.
Cement dust is one of the priority pollutants that must be considered when organizing air quality monitoring. Effective atmospheric monitoring of dust pollution of the air environment allows you to obtain up-to-date data on dust concentration, analyze trends of change and assess the impact on human health and the environment.
Reducing the technogenic impact of aerodisperse systems formed as a result of cement production is an important task to ensure environmental safety.
We conducted a detailed analysis of the literary data of this problem and developed a mathematical model for predicting the distribution of cement dust in residential buildings. Invention proposes improvement of dust-collecting equipment in cement production that allows to reduce emissions of cement dust into atmosphere by 10-15%.
