Abstract

One of the most important ways to increase the efficiency of technological processes is to improve the column heat-mass transfer apparatuses. The design of a jet-film contact device for carrying out the heat-mass transfer processes within gas-liquid systems has been developed. The advantage of this device is a low hydraulic resistance and high mass transfer efficiency with relatively low energy demands. The development of a new technical solution has been carried out with the software module. The separation efficiency of the contact device with its different geometrical dimensions and diameters of the collected drops has been studied. It is established that the greatest separation efficiency of the contact device is provided when its geometrical constant is equal to 0.5, and medium dispersed aerosol particles with a diameter of 20 µm are collected by 99.5%. The high collecting efficiency at small geometrical constant of contact device is explained by the creation of large centrifugal forces due to small radii of gas flow vortices.
