Abstract

Abstract This study uses the CFD technique to investigate the influence of a twisted inverted hybrid solid cone (TIHSC) placed at the gas cyclone dustbin on the separator performance. This new design improves the stability and reduces the length of the vortex finder, resulting in a stronger swirl in the cyclone with a higher tangential velocity. The study showed that an increase in the height of the TIHSC increases the maximum tangential velocity up to 2.9 times the inlet velocity. Overall, using TIHSC leads to a significant increase in particle separation efficiency compared to the conventional cyclone. In addition, with an increase in the height of TIHSC, the pressure drop significantly decreases while the separation efficiency increases. For the optimized model, the particle cut size improves from 0.97 to 0.85 µm at 50% separation and from 6.2 to 4.7 µm at 100% separation, while the pressure drop is reduced by 12.7%.

垃圾箱倒置混合固体锥体气体旋流器的性能分析

摘要本研究采用CFD技术研究了放置在气体旋流器垃圾箱中的扭转倒置混合固体锥体（TIHSC）对分离器性能的影响。这种新设计提高了涡流探测器的稳定性并缩短了其长度，从而使旋流器中的涡流更强，切向速度更高。研究表明，TIHSC高度的增加使最大切向速度增加到入口速度的2.9倍。总体而言，与传统旋风分离器相比，使用TIHSC可显著提高颗粒分离效率。此外，随着TIHSC高度的增加，压降显著降低，分离效率提高。对于优化模型，颗粒切割尺寸从0.97提高到0.85 µm，分离度为50%，从6.2到4.7 µm，同时压降降低12.7%。版权所有©2023美国气溶胶研究协会

期刊介绍： Aerosol Science and Technology publishes theoretical, numerical and experimental investigations papers that advance knowledge of aerosols and facilitate its application. Articles on either basic or applied work are suitable. Examples of topics include instrumentation for the measurement of aerosol physical, optical, chemical and biological properties; aerosol dynamics and transport phenomena; numerical modeling; charging; nucleation; nanoparticles and nanotechnology; lung deposition and health effects; filtration; and aerosol generation. Consistent with the criteria given above, papers that deal with the atmosphere, climate change, indoor and workplace environments, homeland security, pharmaceutical aerosols, combustion sources, aerosol synthesis reactors, and contamination control in semiconductor manufacturing will be considered. AST normally does not consider papers that describe routine measurements or models for aerosol air quality assessment.
