Problems solved by technology

The problem with the former is that it is difficult to achieve continuous enrichment, while the problem with the latter is that gas turbulence and molecular diffusion can easily cause remixing of oxygen and nitrogen, which greatly reduces the enrichment efficiency of oxygen.

Embodiment Construction

[0030] 1 to 5 are specific embodiments of the present invention.

[0031] As shown in Figure 1, the gap formed between the magnets of the laminated magnet array is the required magnetic field space and also the air passage.

[0032]It can be seen from Figure 2 that the magnetic field inside each layer of air channel (or magnetic field space) is symmetrically distributed in the width direction of the magnet, and the magnetic field is almost uniform in the center of the magnetic field space and nearby areas, and drops sharply near the boundary of the magnetic field space. Therefore, there is a magnetic field gradient pointing to the interior of the magnetic field space near the boundary of the magnetic field space. As shown in Figure 3, the magnetic force received by oxygen molecules in this gradient magnetic field area points to the interior of the magnetic field space, while the magnetic force received by nitrogen molecules and other gas molecules points to the interior of the ...

Abstract

A laminated magnet array architecture device for gathering oxygen of air through magnetism and a method thereof belongs to gas separation technique field. The device comprises: a laminated magnet array, a magnetic field space, fluid damping layer on opened border of the magnetic field space, a air source, a buffer, a air delivery pipe, an inlet transition section, an outlet transition section, oxygen enriched air delivery pipe, valves, nitrogen enriched air delivery pipe, a shell and an electric heater of oxygen enriched air outlet. The method is that air is injected into a magnetic field space with an opened border and a gradient magnetic field which gradient direction points to inside on the border, when air outflows from the opened border, oxygen molecules of air are constrained in the magnetic field by that the gradient magnetic field acts force on oxygen molecules. The invention has advantages of simple structure, large amount of treated air, low energy consumption, long service life and wide adaptability.

Description

technical field [0001] The invention belongs to the technical field of gas separation, and provides a laminated magnet array structure device and method for realizing oxygen enrichment in air by using magnetic force. Background technique [0002] In the 1980s, foreign scholars began to study the oxygen enrichment technology based on the behavior of magneto-induced gas flow. Domestic reports on this research began in the mid-1990s, but the progress has been very slow. To sum up, there are two main methods of using magneto-induced gas flow behavior for oxygen enrichment: one is to use the high gradient magnetic field existing near the surface of the magnetized magnetic wire to capture oxygen molecules to achieve oxygen enrichment; the other is to enrich oxygen by A gradient magnetic field is arranged in the gas flow channel, relying on the magnetizing force generated by the gradient magnetic field to separate the travel trajectories of oxygen and nitrogen to achieve oxygen enr...
