Industrial carbon dioxide (CO₂) emissions from sugar factories are significant in volume and need to be urgently reduced. The analysis of possible strategies for minimizing the anthropogenic impact on the environment indicates the feasibility of modernizing the first and second carbonization equipment. In particular, installing ejection devices with a dispersed jet of liquid in the suprajuice space of carbonizers is promising. This approach to modernizing devices allows not only to reduce CO₂ emissions by 20%, but also to increase the efficiency of purifying diffusion juice from unwanted impurities. Computer modeling was key in designing and optimizing the proposed technical solution. The flow dynamics and the efficiency of phase mass transfer in various configurations of ejection devices were simulated using CFD analysis. This made it possible to determine the optimal parameters of the active nozzle and ensure a uniform distribution of the gas phase in the reaction volume. The results of experimental studies indicate a significant dependence of the volumetric ejection coefficient on the design of the active nozzle. The highest value of the ejection coefficient, up to 7, is achieved by using an innovative centrifugal-jet nozzle with open supply channels inclined to the nozzle axis at a nominal liquid supply pressure of 0.2 MPa.

摘要

Industrial carbon dioxide (CO₂) emissions from sugar factories are significant in volume and need to be urgently reduced. The analysis of possible strategies for minimizing the anthropogenic impact on the environment indicates the feasibility of modernizing the first and second carbonization equipment. In particular, installing ejection devices with a dispersed jet of liquid in the suprajuice space of carbonizers is promising. This approach to modernizing devices allows not only to reduce CO₂ emissions by 20%, but also to increase the efficiency of purifying diffusion juice from unwanted impurities. Computer modeling was key in designing and optimizing the proposed technical solution. The flow dynamics and the efficiency of phase mass transfer in various configurations of ejection devices were simulated using CFD analysis. This made it possible to determine the optimal parameters of the active nozzle and ensure a uniform distribution of the gas phase in the reaction volume. The results of experimental studies indicate a significant dependence of the volumetric ejection coefficient on the design of the active nozzle. The highest value of the ejection coefficient, up to 7, is achieved by using an innovative centrifugal-jet nozzle with open supply channels inclined to the nozzle axis at a nominal liquid supply pressure of 0.2 MPa.
