FIELD: process engineering.
SUBSTANCE: invention relates to method of dedusting to be used in heat engineering, ferrous and nonferrous metallurgy. Proposed method comprises feeding gas to be cleaned into cyclone with top axial exhaust branch pipe, gas cleaning by centrifugal forces in forward motion of revolving flow from top to bottom and reversing cleaned flow upward, collecting entrapped dust in dust collector, spraying additional coagulating fluid jets onto collected dust flow to make mix of dust and fluid, pelletising entrapped dust and fluid mix at roller press arranged at dust collector bottom. Note here that linter finer particles of 0.01-1.0 mm-dia are fed in amount of 0.01-0.5 kg/m3 into cyclone top, in gas being cleaned.
EFFECT: higher degree of cleaning, higher strength of pellets.
