Abstract
The article describes the solution to the problem of environmental protection from the impact of the machine assembly department of a shipbuilding production in the Upper Volga basin. The purpose of this work is to study the pollution sources and to design an engineering protection for the atmosphere from this impact, as well as the economic justification of the proposed measures. The problem of environmental protection is particularly relevant in industrial manufacturing. Pollutants have a harmful effect on the environment and especially on people working for heavy industry. Therefore, engineering protection of workers during the production is an urgent task. In this work, the mass of harmful substance emissions was determined, their concentration was calculated and the maximum permissible concentrations were identified. The calculation of the required purification from all contaminations of the machine assembly department was performed. The height of the release point above the ground is calculated. Based on the calculations, the necessary equipment was selected and an aerodynamic calculation of the exhaust ventilation system was performed. The amount of prevented economic damage due to the implementation of the designed environmental measures for the machine assembly department of the shipbuilding industry was determined.
Highlights
Environmental pollution is a global problem of the present time, which is regularly discussed in the news and scientific communities [1,2]
In the machine assembly department, harmful emissions of oil and emulsifier vapours, dust, wastewater, as well as waste intended for general and underground disposal are generated during production activities
The study was conducted based on the machine assembly department of the mechanical workshop of the shipbuilding plant in the Upper Volga basin
Summary
Environmental pollution is a global problem of the present time, which is regularly discussed in the news and scientific communities [1,2]. Most negative environmental consequences of human activity cause atmosphere change - its physical and chemical composition. This leads to an increase in the number of people suffering from chronic bronchitis, asthma, allergies, ischemia, and cancer, especially among the urban population [6,7]. Man-made impacts on the atmosphere have caused such global changes as the "greenhouse effect", ozone layer depletion, and acid rain. The environmental situation is unfavourable in cities where the largest industrial facilities are located [10]
