Application of dispersal analysis of dust in the air of working zones in examination of physicochemical properties of ventilation emissions of asbestos-cement enterprises

Abstract

Abstract The authors implemented a dispersion analysis of dust of asbestos cement, selected from the process equipment, aspiration systems of molding shop, general exhaust ventilation and from the air of sanitary protection zone. Were researched aerodynamic performance characteristics of dust. Established the dependence of dust subsidence in relation to the median particle diameter in the logarithmic grid as a random variable. Performed a comparative analysis of the main indicators of technological emissions of dust in the atmospheric air, while using the standard methodology in dispersion of harmful in the atmospheric air, accepted in Russia, and methods for calculating emissions from unorganized sources. Obtained the ratio of dust subsidence for asbestos-cement dust by two methods.
