Organizing air change in dyeing shops and cleaning of the exhaust air are of great importance for providing the technological and comfortable parameters of indoor climate, and for protecting the environment from polluting emissions. The article considers the methods of painting metal products and gives characteristics of the used paints. A list of noxious substances, evolved at painting metal products, and their influence on human’s health, is presented. Through an example of a dyeing shop at the ОАО «Belagromash-Servis named after V.М. Ryazanov», the existing general-dilution and local ventilation systems are analyzed. With account of the technological process and the location of paint stations an exhaust ventilation system has been developed. The designs and arrangement of exhaust hoods are suggested, which prevent hazardous substances from getting from a metal products painting station to work area. For the aspiration system a centrifugal bubble unit (CBU) with the exhaust air cleaning efficiency is selected. The motion model of air, removed from a paint station, and the distribution of noxious substances in it, is calculated in Solid Works.
