摘要:基于FLUENT软件,使用欧拉-拉格朗日法作为基本框架,对某钢厂1、4期7 m大型焦炉炭化室压力控制管道进行数值模拟研究。高温荒煤气为连续相,喷雾液滴为离散相,考察不同荒煤气入口速度、翻板倾斜角度α等对管内流场的影响,以及荒煤气流速、温度对喷雾液滴蒸发时间的影响。此外,在无喷雾液滴喷洒时,对翻板处局部阻力系数ζ与α的关系进行探究。结果表明:α越大,ζ越大,当α=87°时,ζ可达到34.59;荒煤气入口速度越大、喷雾液滴质量流量越小,监测点温度越高,最高温度为876.69 K;荒煤气入口速度以及α越大,监测点压力越大,最大压力为1799.24 Pa;荒煤气入口速度越大、温度越高,喷雾液滴最大蒸发时间越短,最短时间为0.350 s。
Pressure control pipeline for the 7 m coke oven carbonization chamber in steel phaseⅠandⅣwas numerically simulated using FLUENT,and the Euler-Lagrange method was used as the fundamental framework.With the high-temperature waste gas as the continuous phase and the spray droplets as the dispersed phase,the effects of different waste gas inlet velocities and flap tilt anglesαon the flow field in the pipeline were investigated,and the influence of the flow velocity and temperature of the waste gas on the evaporation time of the spray droplets were investigated.Furthermore,the investigation was conducted into the relationship between the local resistance coefficientζat the baffle andαin the absence of spray droplet spraying.The results indicate that asαincreases,ζalso increases.Whenαis 87°,ζcan reach 34.59.Moreover,higher raw gas inlet velocities and smaller mass flow rates of spray droplets result in elevated temperatures at the monitoring point,with the highest temperature recorded at 876.69 K.The larger the raw gas inlet velocity andα,the greater the pressure at the monitoring point,reaching a maximum of 1799.24 Pa.Additionally,higher raw gas inlet velocities and temperatures lead to shorter maximum evaporation times for spray droplets,with the shortest recorded time being 0.350 s.
