  • On the evaluation of dust characteristics using dispersed analysis of variance of additive-simplex type to reduce particle leakage out from the dust in the dust aspiration’ collectors building industry

    The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems for the aspiration schemes of the construction industry/ It was proposed use additive-integrated dispersive analysis of variance of dust particles emissions throw out into the atmosphere by aspiration systems. The article proposes the improvement of complex analysis of variance using hydrodynamic criteria in output functions. Modified output data and additive-simplex allows getting approach to evaluate characteristics - equivalent sizes and speeds of sedimentation-soiling of dust particles with a higher degree of accuracy of the results. It makes possibility to determine the ranges of size’s and velocities’ changes with real ability. It is possible to obtain more reliable data of sedimentation rates and equivalent particle sizes for the studied dust samples of building materials using the distributions of the hydrodynamics criteria. Analytical approach to determining the density’ distribution of the numerical values of the hydrodynamics criteria in the output function allowed us to clarify the more real values of sedimentation rates and the equivalent particle sizes and the range of their changes both. This way analysis of variance of dispersed dust particles could call additive-complex or simplex approach. The obtained regressions in processing the research results were used in the development of devices for capturing dust of dispersed building materials from emissions. This way could significantly reduced dust leakage out from aspiration collectors of decreasing dust systems while purifying emissions at the building enterprises. This approach is one of the most effective ways to improve the environmental safety of the building industry.

  • Experimental evaluation effectiveness of wet dust separator in the cutting dusting aspiration system of kiln expanded clay oven

    This article describes a way of reducing dust emissions of pollutions exhausted in the atmosphere in the manufacture of building construction materials (expanded clay aggregates, asbestos cement, etc.) applying by approach of desire and the development of precipitators. This promising method based on the results of analysis of variance expanded clay dust, and other building materials proposed generalized approach to the definition of the hydraulic size (effective size' diameter) of dust particles. Proposed method was tested and applied in practice to determining the functional dependence of the integral (cumulative) distribution of dust particles on the equivalent size (effective size). It was mentioned to need to make rationing (norm of containing) dust РМ2.5 и РМ10 fractions in exhausting emissions of pollutions of building construction materials in atmosphere based on the results of analysis of variance volume' data fractions of dust РМ2.5 и РМ10. It is reasonable to use the results of analysis of variance for determination and evaluate equivalent size of dust particles for modeling dispersion and stratification in atmosphere. There described a practical way to determine the critical (minimum) is equivalent to the size of dust particles, maximal potential degree of dust separation in trapped dust cleaners (cyclones, inertial collectors and etc.) from powder and gases flows in decreasing dust aspiration and ventilation schemes in this paper. It were presented some principles of the development of new designs and highly efficient dust different kinds of precipitators (cyclones, inertial collectors) with significant meaning' of separation' degree using the results of analysis of variance of captured dust.
