In recent years, many hospitals have begun to adopt their own oxygen production and supply mode to effectively meet the oxygen consumption in medical rescue. PSA medical oxygen generator has the advantages of simple oxygen supply operation, fast oxygen production and high purity, which reduces the burden of medical work and facilitates medical staff and patients.

 

In order to ensure the oxygen purity and efficiency of medical oxygen generators, and to ensure the smooth oxygen production during the large-scale use of medical oxygen generators, NEWTEK group has conducted research and analysis on the use and maintenance process through years of continuous after-sales return visits to global customers using equipment, grasped the key points of possible problems in use, solved them in time and carried out subsequent maintenance work.

 

 

Pressure swing adsorption (PSA) is based on the different adsorption of oxygen and nitrogen by molecular sieves. Zeolite molecular sieves are used as adsorbents to separate oxygen and nitrogen in the air, thereby selectively adsorbing oxygen in the air.

 

The components of PSA oxygen generator include: air compressor, main line filter, air balance tank, oxygen generator host, sterilizing filter, oxygen pipe installation, etc. On this basis, the oxygen generator needs to be equipped with 2 sets of 10-bottle busbars as emergency backup oxygen sources during use. Molecular sieves are specifically composed of many tiny granular components. The mass fraction and surface area of molecular sieves are not low. Generally speaking, the surface area of each gram of molecular sieve can reach 800-1000㎡/g. After being compressed, the air passes through the air purification system to remove impurities such as oil, water, and solid dust, and then enters the adsorption tower equipped with zeolite molecular sieves. Nitrogen, carbon dioxide, and water vapor are adsorbed by the molecular sieves in large quantities. Oxygen passes through the adsorbent due to its high diffusion rate to achieve separation, and oxygen is directly obtained from the compressed air. In order to ensure that the amount of oxygen provided is continuous and stable, the equipment generally sets up two or more adsorption towers, one of which plays the role of adsorption, and the other is used for analysis to regenerate the adsorbent and reuse it repeatedly. Switching is carried out at appropriate times to ensure continuous production of oxygen with a concentration of 90% to 94%.
