FIELD: process engineering.
SUBSTANCE: invention relates to gas cleaners and can be used for removal of black stock particle from flue gases and for separation of the other aerodispersed systems. Claimed process comprises the feed of aerosol from above downward via filtering granular ply of carbon block pellets sized to 0.5-3.0 mm, with bulk density of 300-1000 kg/m3 and filtering ply height of 100-200 mm. Prior to feeding from above downward said aerosol is forced through filtering granular ply of carbon block pellets from below upward at the rate of 0.5-1.5 m/s for 20-40 seconds at intervals of 3-20 min.
EFFECT: higher efficiency of cleaning, lower costs.
