FIELD: the invention refers for controlling disperse compound of pulverized blow-outs and definition of fractional compound of powdered materials.
SUBSTANCE: a dust-gas flow goes past a cascade of three installed in series single-pass small low-pressure areas where it is subjected to twisting with the aid of propellers. The density of powdered material, mass of captured dust in each single-pass small lower pressure area is determined, integral effectiveness of dust catching in small lower pressure areas is calculated. These data and also data about the diameter of the small low pressure areas and spending velocity of the passing dust-gas flow through the cascade of the single-pass small low pressure areas are introduced into a computer. Using these data disperse compound of powdered material is determined by deciding retroactive task with the aid of a numerical method.
EFFECT: accuracy and rapidity of definition of disperse compound of powdered material.
