摘要：Non-thermal cyclonic separation, driven by particle self-rotation and revolution, revolutionizes energy efficiency and pollution reduction. However, understanding fluid oscillation separation remains incomplete in terms of mechanism. In this study, the liquid oscillation separation characteristics in particle macro-channels in the cyclone were analyzed by mathematical models and high-speed cameras. The coupled centrifugal acceleration of the liquid in the particle macro-channel can reach 579.3 m/s2 and oscillate with a period as short as 8.2 ms. At 25°C, the non-thermal separation efficiency of liquid in particle macro-channel reached 92% in just a few seconds in cyclone. The rate at which the liquid in the particle was separated by the cyclone can be up to 19,377 times the rate at which it was separated by evaporation. The feasibility of non-thermal oscillatory separation by cyclone is confirmed, offering a theoretical foundation for the separation of liquid in porous particles, like sludge, biomass, and lignite. ? 2023, The Authors.
