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 10cm,regeneration mass of packed material whose density is 34.68m2/m3 is more than that of 17.34m2/m3.However,the effect of density on Sh is different.When the air flow...
