New Industrial Eco-Technologies Using the Effects of Hydro-vortex Dedusting

Abstract

The genesis of industrial ecology, the analysis of the main stages in development of technology and eco-technology, allows to confirm that they are not effective enough in ensuring safety and sanitary-hygienic conditions. The introduction of promising innovative technologies, the growth of labor productivity is often limited by parameters of ensuring controllability of technogenic processes, in particular, localization of explosions of aerosol dust mixtures. A method of hydro-vortex dedusting is suggested based on the principle of circulating orthokinetic hetero-coagulation in the system “liquid-solid”, graphical-analytical model of hydro-vortex inertial orthokinetic hetero-coagulation. Expressions for effective values of the Stokes and Reynolds criteria under conditions of hydro-vortex hetero-coagulation were modified. Equations are obtained for calculating the amount of decrease in the total energy consumption required for absorption of dust particles, the effective wetting contact angle and minimum diameter of dust particles to be absorbed during hydrovortical heterocoagulation in a function of angular velocity of liquid droplet rotation. A decrease in the energy barrier under conditions of hydro-vortex coagulation is established, being caused by an increase in the effective values of the Stokes criterion in comparison with the values obtained without taking into account rotation of the liquid drops. It is shown that hydro-vortex dedusting increases efficiency of dust suppression, localization of dust mixture explosions, significantly reducing the size of dispersed dust composition, ensures the growth of resource efficiency of eco-technology due to reducing of water consumption.
