The article is devoted to the improvement of environmental safety while reducing dust emissions by decreasing dusting schemes of aspiration in construction industry. The use of high-performance devices with combined scrubbing circuit, reducing leakage’s degree of dust particles throw out from aspiration cutting dust schemes is one of the most promising and effective ways to implement environmental-protection policy processes in environmental safety of a number of dispersion-bulk construction materials. Perspective approach to reduce dust emissions in cement producing enterprises is described in this article. Data on industrial study of aspiration systems and the results of tests of experimental industrial installations in cement production are presented, as well as summary results of full-sized determination of power of dust emission, dust of expanded clay and sand produced by the equipment, workplaces and aspiration schemes of expanded clay and cement manufacturing enterprises. The results of analysis of variance dimension dust particles and experimental determination of the degree of slipping and leaking out of collecting dust devices were used for elaboration, design and development of the new wet dust cleaner-separator. The article provides the description of one of the offered structures of experimental industrial installations with wet cleaning of dust collector that were tested at the industrial plants. Experiments to get leakage's degree of dust particles are carried out. On the basis of statistical processing of the experimental results were obtained the dependences of the coefficient of leakage of dust’s particles in these wet dust cleaners-separators within the studied work range of aerodynamic modes.
