Abstract
Mathematical description of the effectiveness of dust suppression with low-grade cultivation in the floor shops of enterprises of the construction industry
Incoming article date: 20.09.2020According to the World Health Organization (WHO), air pollution from solid particles, which causes numerous diseases, leads to several hundred thousand premature deaths in the European Union and up to three million in the world, is one of the most serious problems for humanity. This article presents the oldest and most commonly used dust control method in the industry for the transport of bulk materials, which is the use of wet liquid spraying systems. The key factors contributing to the fight against dust are indicated, the possibility of using surfactants is considered. The authors investigate such an urgent problem today as the further development and study of methods of dust removal in industrial construction. The main place in the article is occupied by the issue of increasing the efficiency of the process of air dedusting by low-pressure irrigation. A method for a mathematical description of this process is proposed. The work contains tables and formulas that allow tracing the process of mathematical transformations. The authors of the article present the results of their research, the final result of which is a mathematical description of the dependence of the efficiency of the dedusting process with low-pressure irrigation, taking into account the accepted assumptions and boundary conditions. At the end of the work, it is concluded that formulas have been obtained for improving the applied method of transportation using bulk materials by a belt conveyor.
