Abstract. The paper is dedicated to reducing the technogenic impact on the environment of using highly efficient apparatus for the complex exhaust gas treatment, operating in the advanced turbulence regime – an apparatus with a regular pulsating nozzle (RPN). Devices with on-load tap-changers are characterized by high efficiency of capturing solid particles of different dispersion (e.g., fog, dust, and smoke), the possibility of self-cleaning of contact elements from sticky dust, low material consumption, and high reliability in operation. Purpose of the study – to obtain analytical solutions for assessing the efficiency of capturing polydisperse aerosols in an apparatus with an on-load tap-changer due to diffusion and inertial mechanisms. The paper proposes a new solution for the minimum effective diameter of aerosol particles that can be captured in devices with an on-load tap-changer and can be used for a wide range of diameters of absorbing liquid droplets and their number in the volume of the apparatus. The calculations allow us to say that the minimum effective diameter of aerosol particles captured by liquid drops in an apparatus with an on-load tap-changer is less than 0.3 microns.

Keywords: high-efficiency equipment, environment, dust and gas emissions, phase contact surface, movable plug, drop, condensation.
