AVOIDANCE OF OCCUPATIONAL RISKS OF WORKERS AND MAN-MADE EMERGENCY SITUATIONS DURING CLEANING OF METALLURGICAL EMISSIONS

Abstract

The article highlights the problem of increasing the level of flue gas filtration at industrial enterprises using the example of the metallurgical industry with the determination of technologically possible ways to increase the level of sulfur removal from gaseous emissions into the atmosphere. This can prevent occupational risks for employees of enterprises due to the reduction of the harmful effects of the components of industrial emissions on occupational health. Increasing the level of understanding of the impact of technological parameters on the target result opens up opportunities for organizing a more balanced and stable flue gas cleaning process. This, in turn, increases the ability of factories to comply with sanitary standards and prevent emergencies of a man-made nature when the maximum permissible concentrations of harmful components in gaseous emissions are exceeded. Solving this problem is possible when using mathematical modeling based on determining the relationship between the level of sulfur removal and the technological indicators of the desulfurization process. Regression analysis was used as a method for building a mathematical model. At the same time, the construction of a multifactorial mathematical model was carried out, based on the industrial parameters of the production of the metallurgical enterprise. The visualization of the obtained results is carried out by presenting the constructed mathematical model as three-dimensional graphs in the form of surfaces with the involvement of some of the technological indicators. The obtained results make it possible to optimize the production indicators to increase the efficiency of the desulfurization of gaseous emissions of the industrial enterprise. At the same time, additional aspects of the relationship between filtration indicators and the degree of purification from harmful components in flue gases are revealed, which allows to establish the most favorable process conditions and can be used not only in the metallurgical industry, but also in the thermal power industry.
