Description

technical field [0001] The invention belongs to the technical field of oxygen production, and in particular provides a device and method for realizing oxygen enrichment in air by utilizing magnetic force generated by a gradient magnetic field. Background technique [0002] The oxygen content in the air is 20.9%, and the air with an oxygen content higher than this value is called oxygen-enriched air. Oxygen-enriched air can be used in medical treatment, fermentation and oxidation process; used in air-conditioned bedrooms and rooms in plateau areas to improve the air quality in the house; used in agriculture to achieve intensive fish farming; used in internal combustion engines, when the circulating oil supply remains constant Under the premise, it can promote the full combustion of fuel and improve the energy conversion efficiency. Under the premise that the excess air coefficient remains unchanged, it can improve the working ability of the internal combustion engine. In addi...

Problems solved by technology

The cryogenic method has high efficiency, complex equipment and large investment, and is suitable for large-scale oxygen production equipment; the adsorption method cannot continuously produce oxygen-enriched air, which cannot meet the requirements of combustion work, and the molecular sieve used for adsorption is also expensive; the membrane method Although oxygen-enriched air can be supplied continuously, the promotion of oxygen-enriched combustion technology is limited due to the high cost of oxygen-enriched membranes, and the fact that they are prone to failure when exposed to water and oil, and their service life is short.
