Working Principle Of Medical Oxygen Generator

Working Principle Of Medical Oxygen Generator

The common type of medical oxygen concentrator is pressure swing adsorption oxygen concentrator, which uses pressure swing adsorption technology to produce oxygen, and can extract oxygen from the air. 

Fill in the medical Oxygen Generator with molecular sieve, molecular sieve surface area per gram can reach 800-1000 m2 / g, in the case of pressure, using molecular sieve technology of physical adsorption and desorption, adsorption of nitrogen in the air, not will be collected by adsorption of oxygen, through carries on the purification treatment, can get high purity of oxygen. 

In the case of reduced pressure on the molecular sieve, the previously adsorbed nitrogen gas is discharged back into the air. When pressurized again, nitrogen can be adsorbed for oxygen production. Therefore, the medical oxygen concentrator can realize periodic cycle oxygen production, which is a dynamic process.

Medical oxygen generator (pressure swing adsorption oxygen generator) oxygen producing process, as shown by psa raw material is the air, the air after filtering (oil, dust, moisture in the air and solid impurity removal) into the compressor compressed, compressed high-pressure air after cooling into the adsorption tower is the adsorption separation, equipped with molecular sieve adsorption tower.

The nitrogen and carbon dioxide will be adsorbed by the molecular sieve, and the gas flowing out of the adsorption tower is oxygen with high purity, which can be used as medical oxygen. Part of the separated oxygen enters the gas storage tank through the one-way valve, decompress by the pressure reducing valve, and then flow out through the flow meter and humidification bottle for user use; The other part of oxygen is in the desorption state of the adsorber for back-blowing cleaning, desorption of nitrogen gas through the muffler discharge.
