Abstract. The article observes the impact factors of heat power engineering enterprises on the environment and ways of anthropogenic impact reduction during the application of ecological security control technological methods. The authors suggest attending to the optimization of specific environmental protection processes during the elaboration of ecological security control technical methods in order to reduce the anthropogenic impact on the environment. At the industrial enterprises it is reasonable to implement the principle of the optimization of the environmental protection processes with the help of the high-intensity purification equipment. The optimization of the environmental protection process involves the choice of the physical-chemical factors such as: thermodynamic, kinetic, mass-and heat-exchanging, hydrodynamic, influence parameters on the heterogeneous, complex systems.According to the results of the systems analysis of impact factors on the efficiency of environmental protection processes, it is suggested to optimize the cleaning equipment due to classified and structural parameters, which would allow design the systematic approaches to the selection of environmental protection equipment in future. The process intensity is considered as an environmental protection process optimization criterion.

The work is devoted to the reduction of the technogenic impact on the environment from the emissions of heat power engineering by using a highly efficient equipment for the complex purification of exhaust gases — a equipment with a regular pulsating plug (RPP). The aim of the study is the physical and mathematical description of the mechanisms of the process of capturing fine dust in a equipment with an on-load tap changer. This goal is achieved by describing the physical picture of the dust collection process in an experimental equipment with an on-load tap-changer; mathematical description of the condensation capture of fine dust; descriptions of the process of droplet distribution in the layer of turbulizing packing elements during upward movement of phases. As a result of calculations, an equation was obtained for determining the radius of a particle in the process of condensation of a vapor-gas-liquid system, which allows one to determine the further possibility of trapping particles due to the inertial or turbulent-diffusion mechanism in the device. An equation is obtained for calculating the diameter of liquid droplets formed during the crushing of liquid flows by turbulizing packing elements, which allows us to conclude that the phase contact surface is developed due to the pulsating movement of packing elements. Studies of the equipment with an on-load tapchanger allow us to speak about the possibility of its use for the complex cleaning of dust and gas emissions from heat power enterprises in order to reduce the negative impact on the environment.

The paper is dedicated to reducing the technogenic impact on the environment of using highly efficient apparatus for the complex exhaust gas treatment, operating in the advanced turbulence regime – an apparatus with a regular pulsating nozzle (RPN). Devices with on-load tap-changers are characterized by high efficiency of capturing solid particles of different dispersion (e.g., fog, dust, and smoke), the possibility of self-cleaning of contact elements from sticky dust, low material consumption, and high reliability in operation. Purpose of the study – to obtain analytical solutions for assessing the efficiency of capturing polydisperse aerosols in an apparatus with an on-load tap-changer due to diffusion and inertial mechanisms. The paper proposes a new solution for the minimum effective diameter of aerosol particles that can be captured in devices with an on-load tap-changer and can be used for a wide range of diameters of absorbing liquid droplets and their number in the volume of the apparatus. The calculations allow us to say that the minimum effective diameter of aerosol particles captured by liquid drops in an apparatus with an on-load tap-changer is less than 0.3 microns.

The article discusses the issues of studying the effect of fine dust on human health using mathematical and statistical modeling. The initial data were statistical data on the volume of emissions of suspended particulate matter into the atmosphere and registered cases of diseases of the circulatory system among the population of Ukraine in 2012–2019. To assess the relationship between several factor signs was used method of correlation-regression analysis. The high connection between the actual statistical data and the data of the model calculation indicates the presence a very strong dependence the incidence of the circulatory system of the population on the emissions of fine dust. The obtained results of the study testify to the confirmation of the risk to the health and life of the population. The coefficients of determination make it possible to assert that the emissions of fine dust are one of the main reasons for the development of diseases of the circulatory system in humans. Among the types of dust that enters the atmospheric air from anthropogenic sources of emissions, the most dangerous type of dust for humans is dust containing solid particles ranging in size from 2.5 to 10 microns.

Revolutionary technologies of nowadays are virtual and augmented reality. Humanity's concern for nature may be affected by their ability to combine reality with the simulated effects of human impact on the environment. An urgent task today is creating software applications to assess the impact of human activities on the environment. Recently, most scientists have been trying to model the impact of various factors on environmental change today and for decades using information technology. Visual models are very impressive and they also make a deep impression on the psychological state of the person. This forces people to use natural resources wisely. In this article we have considered the sequential process of building and implementing models for assessing the impact of pollutants from a stationary emission source. We have created a software product that helps to show visually how the emissions of a chemical plant are spreading to the surrounding city. The harmfulness to the city of the cloud into which emissions are converted can also be calculated by the program. We have implemented a number of functions responsible for emission modeling, taking into account different conditions.
