Paper shows theoretical and experimental analysis of the aerosol wet dedusting process, realised in the apparatus of dispersive and barbotage working regime. The construction, operation principle and process efficiency equations have been shown. Fractional dedusting efficiency and the ability to seaprate condensating fractions hard to remove. Exploatation tests carried out in the metalurgical plants have proved the design usefulness for concurrent dedusting and demisting of exhaut gases.
