Abstract
This paper describes the benefits of a regular structured zigzag packing. The task of further research has been determined. To carry out the experiment and further comparison, three types of zigzag packing were developed, the difference of which was in the length of the side of the cross section of the cell channel. Each of the packages was installed with a twist of twenty degrees from each other. For comparison, one of them was aligned coaxially. The research aims to study fluid dynamics and mass transfer efficiency. Based on the experimental data, graphical dependences of the hydraulic resistance of the dry and irrigated packing, as well as the efficiency of mass transfer for the gas-liquid system, were constructed. The hydrodynamic modes of operation of the nozzles and at what speed the entrainment of liquid drops is achieved are determined. Based on the results of the experiment, the height of the transfer unit was calculated. A conclusion is made about the influence of the length of the side of the cross-section of the cell channel on the hydraulic resistance, the efficiency of mass transfer and the height of the equivalent theoretical plate of regularly-structured zigzag nozzles.
