MODIFICATION OF THE TECHNOLOGY OF HYDRO VORTEX COAGULATION FOR A STEADY GROWTH OF THE EFFICIENCY OF LOCALIZATION OF FINE DISPERSED COAL DUST EXPLOSIONS

Nosyrev M. B., Makarov V. N., Ugolnikov A. V., Makarov N.V.

Sustainable development of mining regions, new technologies implementation providing the effective extraction and advanced processing of mineral raw materials is being constrained by the imperfection of dust suppression technologies, localization and liquidation of dust-and-gas aerosols explosions. Based on the Helmholtz theorem, the hypothesis of the uniformity of the traditional and vortex coagulation equations, the Biot-Savart formula, the Fourier rule, criteria equations of hydro vortex coagulation are developed. The influence of the liquid droplets rotation in the process of hydro vortex heterogoagulation, reducing the energy requirement for the total absorption of explosive aerosols. The tests have confirmed the validity of similarity criteria of hydro vortex inertial orthokinetic heterocoagulation, the reduction in the minimum size of the absorbed dust by four times, the efficiency increase in dust catching up to 99 under simultaneous reduction of 20 % in water discharge in comparison with the traditional high pressure wet dedusting.
