| 摘 要： | 为了研究柱塞式气力输送气固两相流的输送特性,对实际的工业气力输送系统进行1∶1实验台改造,首先进行了粉煤灰在输送管内的流动模式试验;然后进行粉煤灰输送压力、输送质量流量特性试验;最后考察了主进气流量、补气流量、助吹气流量对粉煤灰输送量、固气比的影响.研究表明:柱塞式气力输送流动模式以密相栓柱流为主,其灰栓长度为0.8-2.3m,移动速度约为2.8-11.3m/s;输送压力与输送流量成双曲线特性,且随着气量的增加输送量增大;主进气流量起主导作用并与输送粉煤灰质量流量成单调上升抛物线关系,与固气比成上凸抛物线关系即先增大后减小.研究结果对柱塞式气力输送系统的工程设计、运行和理论研究提供依据并具有指导作用.
