specific Embodiment approach 1

[0024] Specific implementation mode 1: see figure 1 Illustrating this embodiment, a device for producing oxygen-enriched air by magnetic multi-radial separation of air described in this embodiment includes an air blower 1, an air filter 2 and a multi-layer magnetic separation mechanism 3;

[0025] The air blower 1 pumps the air into the air filter 2, and after being filtered by the air filter 2, it enters the multi-layer magnetic separation zone in the multi-layer magnetic separation mechanism 3. The multi-layer magnetic separation zone makes the oxygen in the air in the electromagnetic field and Under the combined action of the gradient magnetic field generated by the permanent magnets, the outermost magnetic separation zone enters the innermost magnetic separation zone in turn, and the oxygen concentration increases layer by layer to realize the separation of oxygen and complete the preparation of oxygen enrichment.

[0031] Specific implementation two: see Figure 1 to Figure 3 Describing this embodiment, the difference between this embodiment and the device for producing oxygen-enriched air by magnetic multi-radial separation described in Embodiment 1 is that the multi-layer magnetic separation mechanism 3 includes a buffer cover 3-1, a sealing cover 3-2, the sleeve unit 3-3 and the coil 3-4;

[0032] The sleeve unit 3-3 is composed of a plurality of coaxial sleeves that are nested in each other, and a layer of annular cavity is formed between any two adjacent sleeves. The annular cavity is a layer of magnetic separation area. The annular cavity of the layer and the cylindrical cavity 3-8 formed by the innermost sleeve constitute a multi-layer magnetic separation zone, wherein the annular cavity of the outermost layer is the nitrogen separation zone 3-5, and the remaining annular cavities and The cylindrical cavity 3-8 constitutes an oxygen-enriched separation zone 3-6;

[0038] Specific implementation three: see Figure 1 to Figure 3 Illustrating this embodiment, the difference between this embodiment and the device for producing oxygen-enriched oxygen by magnetic multi-radial separation of air described in Embodiment 2 is that the inner wall of the sleeve in each layer of the magnetic separation zone is provided with steel The wool 3-7-2, the steel wool 3-7-2, the permanent magnet magnet group 3-7 and the coil 3-4 work together to change the magnetic field gradient in the magnetic separation zone.

[0039] In this embodiment, a magnetic field with radial gradient changes is formed around the permanent magnet magnet group 3-7. After the coil 3-4 is energized, a magnetic field with radial gradient changes is formed around it. The steel wool 3-7-2 acts to strengthen the magnetic field gradient. At the same time, a radial gradient magnetic field will also be formed. The radial magnetic field strengths generated by the three are superimposed, whi...

Abstract

The invention provides a device for preparing rich oxygen from air through magnetic-method multi-radial separation and relates to the field of preparation of the rich oxygen, aiming at solving the problems of an existing magnetic-method rich oxygen device that the occupied area is large and the efficiency of preparing the rich oxygen is low. The device comprises an air blower, an air filter and amultilayered magnetic separation mechanism, wherein the air blower is used for pumping the air into the air filter; after the air is filtered through the air filter, the air enters a multilayered magnetic separation region of the multilayered magnetic separation mechanism; oxygen in the air sequentially enters an innermost layer magnetic separation region from an outermost layer magnetic separation region in the multilayered magnetic separation region under the common effect of a gradient magnetic field generated by an electromagnetic field and a permanent magnet; the concentration of the oxygen is gradually raised layer by layer so that the separation of the oxygen is realized and the preparation of the rich oxygen is finished. The device provided by the invention can be widely applied tothe field of rich oxygen preparation including combustion, metallurgy, military, chemical industry, medical treatment, domestic application and the like.

Description

technical field [0001] The present invention relates to the field of preparing oxygen enrichment. Background technique [0002] Oxygen-enriched air is widely used in industry and daily life. Replacing ordinary air with oxygen-enriched air in industrial production such as power generation, cement, and metallurgy can significantly reduce energy consumption in the production process, save costs, and improve product quality. The introduction of oxygen-enriched air into the engine compartment at certain stages can significantly improve its performance. In medical treatment, it is safer to use high-pressure gas cylinders by directly separating air as an oxygen-enriched source. [0003] Among the existing devices and methods for preparing oxygen enrichment, the magnetic adsorption separation method has broad prospects. The basic principle is that oxygen in the air is paramagnetic, nitrogen is diamagnetic, and the magnetic susceptibility of the two differs by several orders of ma...
