The invention discloses a three-tower series connection pressure swing adsorption device and an adsorption process, which adopt a mode of simultaneous adsorption of one set of pressure swing adsorption device and three adsorption towers, and obviously improve the yield and reduce the energy consumption and the equipment investment on the premise of ensuring the quality of product gas. When the three-tower series pressure swing adsorption process provided by the invention is used for performing pressure swing adsorption hydrogen extraction, the yield of the product hydrogen is obviously higher than that of the existing primary pressure swing adsorption hydrogen extraction device on the premise of ensuring that the purity and impurity content of the product hydrogen meet the requirements of high-purity hydrogen; when the three-tower series pressure swing adsorption process provided by the invention is used for producing oxygen and nitrogen through pressure swing adsorption, the unit oxygen production power cons
