Complex dispersed analysis of particles applying in output hydrodynamic criteria decreasing dust leakage'throw collectors of aspiration in construction industry

摘要

The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems using additive-complex dispersive analysis of variance of dust emissions 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 approach to the evaluation of characteristics - equivalent sizes and speeds of sedimentation- soiling of dust particles make it possible to determine the ranges of their changes with a higher degree of accuracy of the results.The distributions of the hydrodynamics criteria values allow us to obtain reliable meanings for sedimentation velocities and equivalent particle's sizes for the studied dust samples of building materials.Analytical approach to determining the density distribution of the numerical values of the criteria allowed clarifying the values of sedimentation-soiling velocities and hydraulic equivalent sizes of particles to get more reliable of their changes ranges.The authors present the most essential regressions and mark to method determining hydraulic work regimes for design dust collectors.This approach is one of the most effective ways to improve the environmental safety of the construction industry.
