An oxygen concentrator is a device used to separate and purify oxygen from the air before outputting pure oxygen. Its working principle is to separate oxygen from other gases such as nitrogen in the air through physical and chemical means, and then output the separated pure oxygen through the output port. Oxygen generators are widely used in industries such as healthcare, metallurgy, energy, food, and semiconductors, and have been widely recognized and applied due to their convenience, safety, and stability.
Oxygen concentrators are essential medical and healthcare equipment that can purify and output oxygen from the air to patients for treatment of respiratory diseases such as acute respiratory distress syndrome, pulmonary heart disease, pulmonary fibrosis, asthma, and other respiratory diseases. It can also help people adapt to high altitude and low oxygen environments, and provide a large amount of oxygen supply in extreme environments such as high and low temperatures. In addition, oxygen generators are also widely used in civilian places, such as hotels, entertainment venues, offices, etc., providing people with safe and convenient oxygen supply.
There are various types of oxygen generators on the market today, and there are various classification methods based on their purpose and working principle. Among them, according to their usage, they can be divided into medical oxygen generators, industrial oxygen generators, and civilian oxygen generators; According to the working principle, it can be divided into compressed air oxygen generator, adsorption separation oxygen generator, molecular sieve adsorption oxygen generator, etc; According to the way of outputting oxygen, it can be divided into fixed flow oxygen concentrators, adjustable flow oxygen concentrators, etc.
Compressed air oxygen generator is a device that uses high-pressure gas to compress, cool, dehumidify, and process a mixture of gases, and then performs membrane separation to obtain high-purity oxygen. This type of oxygen generator has the characteristics of simple and easy operation, long service life, and no external interference. However, due to the involvement of high-pressure gas in its working process, it has a high risk.
The adsorption separation method of oxygen machine utilizes the affinity difference between oxygen and nitrogen to separate the mixed gas on the macromolecular sieve through adsorption and selective adsorption, achieving the separation of oxygen and nitrogen. This type of oxygen generator has simple operation, stable treatment effect, and long service life, but it occupies a large area and requires periodic replacement of large molecular sieves.
The molecular sieve adsorption oxygen generator uses a molecular sieve oxygen generator to separate the size characteristics of gas molecules, separating oxygen and nitrogen from the air to produce pure oxygen. This type of oxygen generator has the characteristics of simple structure, long service life, safety and reliability, and low energy consumption, and is currently a widely used oxygen production equipment.
Overall, oxygen concentrators are a convenient, safe, and stable oxygen supply equipment with a wide range of application prospects and market demand. In the future, with the development of technology and people's emphasis on health, oxygen generators will continue to develop new technologies and equipment, making them more portable, compact, and accurately meeting the needs of different fields for pure oxygen.
