Problems solved by technology

[0002] At present, the methods for producing oxygen from air separation mainly include deep freezing method, pressure swing adsorption method and membrane method. The medium deep freezing method is the most mature and widely used in industry. The oxygen production process by this method is complicated, the equipment is huge, and the investment is large.
The pressure adsorption method and the membrane method still have a certain distance from industrial application due to the problems of high energy consumption for oxygen production, expensive separation elements (molecular sieves and membranes), and short service life.

Abstract

The present invention relates to method and device for magnetizing air and separating oxygen. The device consists of mainly permanent magnet to constitute inhomogeneous magnetic field, oxygen passage, electric oxygen heater and other basic parts. After air enters inhomogeneous magnetic field, oxygen is magnetized to raise the bulk magnetic susceptibility, attracted by the magnetic poles into the oxygen passage, and heated to lower bulk magnetic susceptibility. The latter cold oxygen is attracted by much greater magnetic force to push oxygen to move forward continuously, forming heat magnetic convection and separating out oxygen from air. The present invention is air separator with low cost, low oxygen making power consumption and long life, and may be used in producing cheap oxygen or oxygen-rich air for industrial and medical use.

Description

Technical field: [0001] The invention relates to a method and equipment for magnetizing air to separate oxygen, especially suitable for air separation to produce low-purity oxygen or oxygen-enriched air. Background technique: [0002] At present, the methods for producing oxygen from air separation mainly include deep freezing method, pressure swing adsorption method and membrane method. Among them, the deep freezing method is the most mature and widely used in industry. The oxygen production process by this method is complicated, the equipment is huge, and the investment is large. The pressure adsorption method and the membrane method still have a certain distance from industrial application due to the problems of high energy consumption for oxygen production, high price of separation elements (molecular sieves and membranes), and short service life. Invention content: [0003] The object of the present invention is to provide a method and equipment for magnetizing air to...
