摘要

摘要: 以軸向流吸附器內部流場為研究對象,采用CFD軟件對其內部氣體流動特性進行數值模擬.比較軸向流吸附器內無氣體分布器、僅加裝單一多孔板氣體分布器、加裝多孔板氣體分布器與單級擋板相結合等3種方式對吸附器內部流場均勻分布的影響.未加裝氣體分布器的軸向流吸附器內部氣流分布嚴重不均;僅加裝單一多孔板氣體分布器的軸向流吸附器內部流場的氣體流動稍有改善,但氣流分布仍不均勻;加裝多孔板氣體分布器與單級擋板相結合的方式,吸附器內部流場的氣體流動得到明顯改善.多孔板氣體分布器與單級擋板組合使用時,保持氣體分布器開孔率不變,開孔孔徑為0.003 m時氣流分布最為均勻,效果最好;保持開孔孔徑不變,氣體分布器的開孔率為0.388時氣流分布最為均勻.

Abstract: The internal flow characteristics of axial flow absorbers were numerically studied by the computational fluid dynamics(CFD) method. The influences of three absorber models on the internal flow uniformity were compared: absorber without a flow distributor,absorber with a single flow distributor,and absorber with the combination of a flow distributor and a baffle. The results show that the flow is severely uneven without a flow distributor,is slightly meliorated with a single flow distributor,and is significantly improved with the combination of a flow distributor and a baffle. For the combined configuration,the best flow uniformities are obtained with the pore diameter of 0.003 m as the pore opening ratio remains unchanged and with the pore opening ratio of 0.388 as the pore diameter does not change.
