Pressure swing adsorption device for hydrogen purification

The utility model discloses a pressure swing adsorption device for hydrogen purification, which belongs to the field of hydrogen purification and comprises a pressure swing adsorption tower, a hydrogen purification tower, a mounting net, a metal palladium block layer, a sliding net and a uniform distribution plate. The pressure swing adsorption tower is used for adsorbing miscellaneous gas in gas, the metal palladium block layer in the hydrogen purification tower is used for adsorbing hydrogen, during use, the metal palladium block layer expands after adsorbing the hydrogen, then the metal palladium block layer located above the mounting net expands and rises, the sliding net is pushed to rise, and the hydrogen purification device is used for purifying the hydrogen. The amount of hydrogen adsorbed by the metal palladium block layer can be judged by arranging the detector for detecting the rising height of the sliding net, when gas flows into the hydrogen purification tower, the uniform distribution plate forc
