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.
