The medical oxygen generator is a medical device suitable for oxygen therapy and health care in medical institutions and families. It uses pressure swing adsorption and other technologies to extract the oxygen we need from the air. The medical oxygen generator is in use. After the air enters the equipment, it is filtered to remove moisture, dust, oil, solid impurities, etc., and then enters the compressor for compression to obtain high-pressure air. After cooling, it enters the adsorption tower for adsorption and separation, and high-purity air can be obtained. oxygen.

The working principle of the medical oxygen generator is to use pressure swing adsorption technology to produce oxygen, which can extract oxygen from the air. The medical oxygen generator is filled with molecular sieve, and the surface area of ​​each gram of molecular sieve can reach 800-1000m2/g. Under pressure, the physical adsorption technology and desorption technology of molecular sieve are used to adsorb nitrogen in the air. The oxygen will be collected, and by purifying it, oxygen with a relatively high purity can be obtained.

In the case of depressurizing the molecular sieve, the previously adsorbed nitrogen gas is re-emitted into the air. When pressurized again, nitrogen can be adsorbed to produce oxygen. Therefore, the medical oxygen generator can realize periodic oxygen production, which is a dynamic process.
