Abstract
The evaluations of the complex analysis’ results of dispersed dust particles using hydrodynamic criteria for decreasing dust leakage out from decreasing dust systems of aspiration’ emissions in the production of building industry
Incoming article date: 02.12.2018The article is devoted to the issue of improving the environmental safety of the construction industry by improving the systems of decreasing dust emissions by aspiration systems using a comprehensive dispersive analysis. There was proposed to develop a promising approach using the criteria of hydrodynamic similarity in the output functions of the complex analysis of variance to increase the efficiency of aspiration decreasing dust systems in this article. The article focuses on the environmental problems of building construction industry. The volume and different kinds of mixtures of bulk building materials and cements to produce various types of concrete construction units and materials are in stable demand every year. It means that average amount of dust particles substances in emissions at the manufacturing production of building materials every year too. The results of studies show that a significant content of fine particles, for example, 10 microns or less is concern in dust emissions systems of aspiration at the building construction enterprises. One of ways to increase the environmental safety is reduction of dust emissions to design dust capturing devices that have low values of slippage out from aspirations’ decreasing dust systems. It was achieved by special complex integrated analysis’ method of variance dust that applies hydrodynamic sedimentation of particles. It is the way to obtain distribution of dimensionless numerical complexes — the hydrodynamic similarity criteria for the dust studied samples. There presented results of experiment that gave more reliable approach to get evaluations of the complex analysis of particles sedimentation velocity’s distributions.
