摘要
为研究氩气流在水平携带床热解管中的运动,设计了水平携带床透明冷态模拟装置.以油雾粒子为示踪粒子,利用PIV技术对示踪粒子在水平携带床管内的速度分布和加速距离进行了实验研究,并对管内气流的速度分布进行了分析.研究结果表明,油雾粒子加入管道后的加速距离约为400mm,在大于400mm的区域内已经较为稳定,速度变化很小;气流在进入管内400~600mm时,处于过渡段的后期或已经进入稳定段.
In order to investigate the movement of argon in pyrolysis pipe of horizontal entrained flowreactor, a transparent apparatus was set up. With oil fog used as tracer particles, velocity distribution and accelerating distance of tracer particles were studied using PIV, argon flow velocity distribution in the pipe reactor was analyzed too. The results showed that the accelerating distances of tracers particle were about 400mm and the change of velocity was very little beyond 400mm. Argon flow was at the end of transition stage or at stable stage after it enter the pipe for 400mm - 600mm.
