Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a digital intelligent oxygen generator system and a control method. Background technique [0002] With the development of economy and society, oxygen generators are not only widely used clinically as a common medical equipment, but also gradually become a common modern medical care method. Clinically, the use of high-concentration oxygen from an oxygen concentrator can treat some symptoms, such as discomfort in the respiratory system and cardiovascular system, symptoms of altitude sickness, distress in pregnant women and fetuses, and sleep hypoxemia. Oxygen concentrator insists on inhaling oxygen to relieve mental fatigue, maintain vigorous energy, improve work efficiency, and improve learning efficiency; at the same time, to a certain extent, it can reduce pollution and harm to the body in harsh environments, delay aging, and enhance body functions.

Problems solved by technology

[0003] The oxygen generator adopts the pressure swing adsorption process at room temperature, and uses molecular sieves to separate oxygen and nitrogen in the air, thereby extracting oxygen. Using molecular sieve physical adsorption and desorption technology, the oxygen generator is filled with molecular sieves, and the air can be compressed when pressurized. Nitrogen is adsorbed in the medium, and the remaining unabsorbed oxygen is collected, and it becomes high-purity oxygen after purification. The molecular sieve discharges the adsorbed nitrogen back into the ambient air during decompression, and can be adsorbed again during the next pressurization. Nitrogen and oxygen are produced. The whole process is a periodic dynamic cycle process. Molecular sieves are not consumed. The molecular sieve oxygen production system absorbs nitrogen in compressed air through molecular sieves, and then sends oxygen to the pipeline to produce oxygen. Molecular sieves Molecular sieve is the key material in the whole system. Molecular sieve is filled in the absorption tower. Because molecular sieve is very sensitive to water molecules, oil molecules and dust, it will cause non-renewable damage to molecular sieve. In addition, due to the limitation of volume and weight of oxygen generator equipment, relatively The oxygen flow rate and concentration of light oxygen generators are not stable enough, and the proportions of carbon monoxide, methane, and carbon dioxide in the oxygen-enriched gas produced by the oxygen generator are also relatively different. Therefore, to eliminate the toxicity of carbon monoxide, it is necessary to ensure the oxygen content in the oxygen-enriched gas Stable, and the existing oxygen generators have a wide range of applications and regions. From plains to high altitudes, atmospheric pressure changes with altitude will have a greater impact on the oxygen generation system. How to ensure the effective use of oxygen generators and apply to Different altitudes are also technical problems to be solved in this field
