Abstract
In order to solve the problem of increasing the efficiency of purification of industrial gas emissions from aerosol particles, the authors developed a jet-film contact device, described the principle of its operation. The results of numerical studies to determine the efficiency of aerosol deposition on a fluid film of a jet-film contact device are presented. The study was carried out in the ANSYS Fluent software package, using the turbulence model of the k-ω SST model. Different variants of the ratio of the height to the width of the structure of the device are considered. The velocity of the gas flow and the sizes of the dispersed particles are changed. It is shown that to achieve high technical and economic performance of heat and mass transfer devices with jet-film contact devices, they should be designed taking into account the choice of optimum values for the height of the downcomer (kb = 0,46÷0,53).
