dc.description.abstract | 本研究使用長140 mm、寬70 mm、高140 mm的迴路壓封閥與內徑52.9 mm的固體下降管。固體粒子採用平均粒徑230 μm,密度2458 kg/m3的玻璃砂。與一般循環式操作不同,僅以迴路壓封閥與下降管進行實驗,以量測固體流量與壓力訊號的方式,探討物料供給室結構、通氣量、通氣位置對迴路壓封閥的固體流量、壓力降所造成之影響。
由實驗結果顯示,固體流量隨通氣量增加而增加,且與通氣位置有關。以迴路壓封閥之供給室底部與側壁為主要通風口時的實驗結果較佳,以輸送室底部為主要通氣口之結果較差。迴路壓封閥內物料供給室體積對固體流量的影響明顯,降低閥內物料供給室體積時,需要較大的通氣量才能達到相同的固體流量。測量迴路壓封閥各點之壓力與觀察實驗過程,發現閥內粒子順暢流出,且閥內壓力高於出口,因此推論迴路壓封閥具有壓封效果。 實驗結果顯示迴路壓封閥單獨操作時仍然能以通入氣體的方式調節固體流量,且具有壓封效果。迴路壓封閥之固體流量與壓力降隨閥內通氣量增加而增加,與循環式操作類似。 | zh_TW |
