Abstract

Air pollution by industrial dust at agricultural enterprises has a multifaceted negative impact, posing a direct threat to personnel health, reducing the service life of equipment and increasing the risk of environmental emergencies. Existing cleaning methods, especially for particles smaller than 10 µm, are often ineffective or energy-intensive. The aim of this study is to provide a comprehensive theoretical justification and develop analytical models for evaluating the efficiency of a new gas-liquid vortex separation device with a tangential vane swirler, combining centrifugal and inertial cross-flow separation mechanisms. Based on an analysis of particle trajectories and mass transfer equations, analytical relationships were developed that allow us to predict the fractional separation efficiency depending on the gas (G) and irrigating liquid (L) flow rates. It was found that efficiency of centrifugal separation is critically dependent on the L/G ratio: increasing the liquid feed reduces flow swirl. Thus, for particles with a diameter of 10 µm, with an L/G ratio of 0.12, the efficiency reaches 80%, but drops to 18% at L/G = 0.47. At the same time, the efficiency of inertial sedimentation on liquid droplets depends on the liquid load, demonstrating a positive correlation with particle size. Increasing the liquid flow rate from 21 to 168 kg/h increases the efficiency of the inertial mechanism for 10 µm particles from 56% to 94%. Calculation of the overall separation efficiency confirms the high potential of the device for capturing a wide fractional composition of industrial dust. The developed models and obtained results provide the basis for designing highly efficient dust removal systems specifically tailored to the conditions of the agro-industrial complex, particularly for feed production and grain processing plants.
