The basic principle of preparing oxygen-enriched air by utilizing magnetization and adsorption separation is that the oxygen molecules in the air have paramagnetism, the nitrogen molecules have diamagnetism, and the magnetic susceptibility of the two molecules is different by several orders of magnitude. When air flows through the gradient magnetic field, oxygen molecules are gathered towards the magnet direction under the magnetization effect, nitrogen molecules escape towards the opposite direction of the magnet under the magnetization effect, the flow directions of the oxygen molecules and the nitrogen molecules are opposite, and the kinetic energy difference between the oxygen molecules and the nitrogen molecules is extremely large, so that an oxygen enrichment area and a nitrogen accumulation area are formed, and further, the air is separated to prepare oxygen-enriched air. However, in the existing device and method for preparing oxygen-enriched gas by magnetic method, there are many problems such as low separation efficiency, low oxygen concentration, high oxygen production cost, large power consumption, large resistance, large noise, large occupied area, high operation cost, difficult maintenance and the like, so there is a need to improve and enhance the existing oxygen production device by magnetic method.
