Abstract
In the article, the object of research is the mode of operation of the existing and created at the cotton cleaning enterprise dust collection equipment and the degree of change in the amount of dust in the air. The methods of research in which modern methods of determining the parameters and aerodynamics of dust collecting equipment, experiments to determine the degree of pollution of the dust flow and statistical data, the development of a mathematical model of the dust flow in the networks of dust collecting equipment, the trajectory of droplets and dynamics, based on the technical characteristics of dust and gas cleaning chamber are presented.
