Abstract

To date, the problem of creating an effective technology for the extraction of fine dust pollution from cotton has not been solved. This article provides a solution to this problem. The socio-economic significance of the study lies in the fact that the proposed device is associated with significant savings in energy costs for cleaning cotton from dust. After the contaminated cotton enters the threshing floor, under great pressure, fine trash settles firmly inside the cotton. It makes it very difficult to process and clean it in cotton factories. Therefore, the cleaning process of cotton has to be repeated several times. The cost of energy consumed during cleaning increases significantly and the cotton fiber quality is reduced. The device proposed in the article cleans the collected cotton from impurities during machine harvesting. The process of cleaning cotton at this stage is very effective. As a result, the cost of harvested cotton is reduced, which increases the income of cotton farmers and workers employed in cotton factories. In addition, it causes an increase in the quality of textile products. Another socio-economic significance of the device proposed in the article is that it can be installed on a cotton harvester and in other places. In addition, it can be used not only to clean cotton but also to clean other substances from fine dust. As a result of practical research, technology has been developed to extract small contaminants from cotton.
