Study on Unpowered Adsorption Treatment Technology for VOC Exhaust Gas Based on CFD
为应对石化企业各场景产生的随机、间歇性挥发性有机物(VOCs)无组织排放问题以及固定式处理装置成本高、场地受限的挑战,拟提出并设计了一种基于原位无动力吸附技术的移动式吸附装置.通过计算流体动力学(CFD)仿真模拟,分析了关键参数对吸附装置内部流体特性的影响规律.探究了VOCs体积分数(0%～5%)、环境风速(0～10级)、流量(10,40 m3/h)及直径(0.8,1.2 m)对吸附装置床层压降、速度分布和风阻的变化规律.结果表明:压降、速度、风阻受VOCs浓度(密度1%～5%、黏度1%～5%)、环境风速(0～10级)、流量(10,40 m3/h)及直径(800,1 200 mm)影响.该研究为移动式吸附装置的设计优化和运行参数控制提供了理论依据,有助于实现低成本、安全的VOCs治理.
To address random and intermittent fugitive VOCs emissions in petrochemical scenarios,as well as the high costs and site constraints of fixed treatment units,this study proposes and designs a mobile adsorption device based on in-situ unpowered adsorption technology.Using Computational Fluid Dynamics(CFD)simulations,the impact of key parameters on the internal fluid characteristics of the device was analyzed.Specifically,the study explored how VOCs volume fraction(0%-5%),ambient wind speed(Level 0-Level 10),flow rate(10 m³/h&40 m³/h),and device diameter(0.8 m&1.2 m)affect bed pressure drop,velocity distribution,and wind resistance.The results confirm that these factors significantly influence the device's performance.This research provides a theoretical foundation for optimizing the design and operational control of mobile adsorption units,facilitating low-cost and safe VOCs management.
