Abstract. The deposition of aerosols from process gas streams are the basis of many technologies in the chemical, petrochemical, coke, oil, gas, food etc. Industrial gases, containing aerosols of different nature of origin polydisperse solid particles (dust, smoke) or liquid particles (fog), must be cleaned. The idea of the author is to develop a mathematical model of the process of trapping waste gases, fogs in intensive nozzles with a developed surface of contact of phases. The vortex flow of the gas-liquid flow and its pulsating nature of the movement contribute to the intensification of the crushing process and coagulation of the drop gas-liquid flow in the layer of a regular moving nozzle. Methods of mathematical modeling of the process of movement of a polydisperse aerosol in a turbulent gas-liquid flow have been used. It was determined that condensation of steam in the cell occurs on the surface of the nozzle and also the formation of new germs of aerosol particles. The size distribution of aerosol particles is due to centrifugal forces. In this case, large particles are removed from the vortex region into a continuous flow, while small particles rotate in a vortex. Coagulation equation describing the change in the particle size distribution function with time, undergoing condensation and coagulation growth. The obtained results of differential and integral-differential equations can be used to describe the formation process and aerosols. Environmental and economic efficiency, as well as the optimal choice of environmental and auxiliary equipment took into account.

Keywords: “wet” cleaning technologies, regular moving nozzle, polydisperse aerosol, gas-liquid flow, condensation-coagulation integration.
