硅胶转轮是实现环境空气湿度控制的主要除湿技术,优化转轮尺寸、降低运行能耗是转轮除湿技术发展的必然趋势。本文基于计算流体力学(CFD)理论研究方法,首先建立并优化了高精度的三维动态仿真模型,针对桥梁缆索保护用的硅胶除湿转轮进行动态仿真,分析讨论了转轮厚度、风速、再生风的风量与温度对转轮除湿量(MRC)和比能耗(SEC)的影响规律,以达到优化转轮设计的目的。研究结果表明:不同风速运行条件下转轮存在最佳厚度,且最佳厚度随风速的增加而增大;相较于原转轮,优化后的转轮可以平均提升10%的MRC,并降低15%的SEC,表明了尺寸优化的有效性。同时发现转轮的SEC会随着再生温度的升高而降低,因此在进行转轮设计时要结合除湿需求,尽量降低再生温度以提高经济性。
Silicone rotor is the main dehumidification technology to realize humidity control of ambient air; optimizing the rotor size and reducing the operating energy consumption are inevitable trends in rotor dehumidification technology development. In this study, based on the theoretical research method of computational fluid dynamics (CFD), we first established and verified a three-dimensional dynamic simulation model of the dehumidification and regeneration process of the rotor, and we conducted a dynamic simulation for the silica gel dehumidification rotor used for the protection of bridge cables, and we then analyzed and discussed the influence of rotor thickness, wind speed, and regeneration wind volume and temperature on the moisture removal capacity (MRC) and specific energy consumption (SEC) of the rotor to optimize the design of the rotor. The purpose was to optimize the rotor design. The results showed that the optimal thickness of the rotor existed under different wind speeds, and the optimal thickness increased with the increase in the wind speed. Compared with the original design, the optimized wheel improved the average MRC by approximately 10% while reducing the SEC by approximately 15%, demonstrating the effectiveness of dimensional optimization. Notably, the SEC decreased with increasing regeneration temperature. Therefore, in practical design, the regeneration temperature should be selected in accordance with the dehumidification requirements and maintained as low as feasible to enhance the overall economic performance.
