METHOD FOR CLEANING AIR FROM DUST Russian patent published in 1995 - IPC

FIELD: mining industry. SUBSTANCE: fed to straight-flow bag filter is dust-air flow. Velocity of dust-air flow is maintained above critical values by factor of dust settling over entire surface of filter. Value of critical velocity is determined by the conditions of equality of forces of breaking away the particle from surface of bag filter and forced applied depending on diameter of dust particles. EFFECT: higher efficiency of air cleaning due to autoregeneration of filter in course of air cleaning. 2 dwg
