RESEARCH OF HYDRAULIC RESISTANCE OF VORTEX RECTIFICATION STAGES

The article deals with the issue of studying the hydraulic resistance of vortex contact stages for rectification equipment used for separation of alcohol-containing solutions obtained on the basis of hydrolysate of vegetable raw materials. Based on the conducted research, the dependences for determining the hydraulic resistance coefficient for axial and tangential swirlers are obtained. It is shown how the design parameters affect the change in the coefficient of hydraulic resistance. Hydraulic resistance is an important hydrodynamic characteristic of contact stages, which characterizes the energy consumption of the gas flow for the mass transfer process and determines the scope of its application in practice. Knowledge of the amount of hydraulic losses in the device is also necessary when calculating the schemes of technological strapping of the device. Currently, there are numerous data on the study of regularities in the domestic and foreign literature.
