[0006] Patent CN101020569A discloses a magnetic oxygen-enriched air machine, which is mainly composed of an oxygen-permeable layer and an oxygen-enriched air pump. The air pump is provided with a shroud with a rotating magnetic field, and the magnetic force generated by the rotating magnetic field is used to gather the air in the oxygen-gathering device. The oxygen on the surface is effectively introduced into the air pump, but there are problems such as the low concentration of enriched oxygen and the small amount of enriched oxygen.
[0007] Patent CN101857200A discloses a new type combined magnetic oxygen enrichment device. The oxygen enrichment device adopts three-stage series oxygen enrichment to increase the oxygen purity step by step. However, in the actual operation process, the higher the oxygen concentration, the more difficult it is for oxygen to escape from the magnetic field.

Abstract

The invention discloses air separation equipment, the air separation equipment comprises an air entraining section and an oxygen-enriched separation section according to the gas flowing direction, anair inlet is formed on one side of the air entraining section, an oxygen-enriched flow outlet and a nitrogen-rich flow outlet are formed in the shell of the oxygen-enriched separation section; an airfilter and an air blower are arranged in the air entraining section; a fixed shaft and one or more than one ionization separation barrel are arranged in the oxygen-enriched separation section, and theionization separation barrel is fixedly connected with the shell of the oxygen-enriched separation section through a connecting plate. The air separation equipment improves the separation effect of oxygen in a magnetic field, and the problem that the oxygen is difficult to separate from the magnetic field in the oxygen-enriched process of the magnetic method is solved.

Description

technical field [0001] The invention relates to the field of gas separation, in particular to an oxygen separation device in air. Background technique [0002] The traditional oxygen production method is air cryogenic fractional distillation, which can produce high-purity oxygen and nitrogen. However, in many occasions, such as wastewater treatment, metal smelting, and chemical waste gas treatment, high-purity oxygen like cryogenic fractionation is not needed, and the amount of enriched oxygen is relatively large. For this reason, people have been pursuing more economical and simple oxygen enrichment methods, such as molecular sieve pressure swing adsorption method and membrane oxygen enrichment technology. [0003] Membrane oxygen enrichment is the use of oxygen-enriched membranes for air separation. Oxygen-enriched membrane technology is advanced and mature. The working principle of membrane separation air is the selective permeability function of the polymer membrane, s...
