摘　　要：使用一种新型多层波纹纤维叠合物填料进行再生实验,在固定溶液流量、密度及温度,空气进口状态下研究风量以及填料层高度、填料层密度等结构因素对再生量,Sh数的影响趋势,并分析了各因素对再生性能的控制机理。研究结果表明:当填料高度为10 cm时,填料密度为34.68 m2/m3的再生量以及Sh数都比密度为17.34 m2/m3的要高。当填料高度为20 cm时,填料密度为34.68 m2/m3的再生量仍然比密度为17.34 m2/m3的要高;但是Sh数则有所变化,在风量较小的情况下,高密度的Sh数比低密度的要高,但随着风量的增大,低密度的变化趋势比高密度的更为明显,风量超过220 m3/h时,低密度的Sh数要比高密度的要高,原因是随着风量的增大压损亦相应增大,从而影响再生效果。A set of experiments were carried out to investigate its regeneration performance varying with air flow and height and density of the honeycomb paper when the inlet air states, solution concentration and flow rate are fixed. The result and analysis are also presented in this paper. From the result of experiment, when height of packed material is 10 cm, regeneration mass of packed material whose density is 34.68 m^2/m^3 is more than that of 17. 34 m^2/m^3 However, the effect of density on Sh is different. When the air flow is low, Sh of high density is more than that of low density. While the air flow is more than 220 m^3/h, the result is opposite. That is because pressure drop would be larger with the air flow increasing.
