Abstract：Based on the analysis method of fluidized bed,the structure of adsorption tower of PSAoxygen concentrator was designed,and the structure of three-dimensional axial fluid molecular sieve bed with Skarstrom cycle was selected,the proper height of the adsorption column is studied by controlling the inner diameter of the bed according to the flow rate of the bed in the adsorption column,and according to the influence of the existence of gas in the column,the reserved space and the splitter plate in the adsorption column were analyzed and designed,and the gas storage capacity of the gas storage tank to the adsorption column system was analyzed and designed.In this paper,the proposed adsorption tower design enhances oxygen production efficiency by more than 40％compared to the current stereoscopic axial flow adsorption tower designs.
