Abstract
The mathematical model of hydro vortex inertial kinematic coagulation is proposed; the model largely improves energy efficiency of coal dust blast isolation. The graphical model of interaction between liquid drop and explosive aerosol particle at the contact zone at the moment of collision in the liquid-solid system is refined using the theory of added vortexes. The hypothesis on weakening of the wedge effect of a gas medium in the zone of contact between the explosive aerosol particle owing to an added vortex caused by the drop and particle rotation, is put forward and proved. The equations are obtained for calculating energy required for total absorption of explosive aerosol particles, minimum diameter of the particles and wetting angle in hydro vortex inertial coagulation.
