Principle of Medical Oxygen Concentrator

The working principle of the medical oxygen generator can be divided into four categories according to the oxygen generation principle of the oxygen generator, mainly including: the principle of molecular sieve, the principle of polymer oxygen-enriched membrane, the principle of electrolysis of water, the principle of chemical reaction oxygen production, etc. The following will give you the details. introduce.

The early principle of oxygen production is chemical oxygen production, that is, using chemical reagents to produce oxygen, because this method cannot continuously supply oxygen for a long time, and the chemical reagents are expensive and the cost of oxygen production is high, which has been eliminated by the market. Molecular sieve oxygen generator uses air as raw material, only consumes electricity, and the raw material is air, without cost, convenient and inexhaustible. , transportation costs and other factors.

Molecular sieve oxygen generator is a rare oxygen generator with international and national standards. The working principle of molecular sieve oxygen generator mainly adopts PSA (molecular sieve physical adsorption and desorption) technology.

The air enters the compressor after being filtered by the intake filter device, and then enters the molecular sieve tower for oxygen and nitrogen separation after compression. Oxygen smoothly passes through the molecular sieve tower and enters the fine sieve tower, while nitrogen is adsorbed by the molecules and discharged into the atmosphere through the separation valve. After the oxygen concentration in the fine sieve tower is further increased, the flow is controlled by the flow control valve, and then humidified by the humidification water tank, and finally flows through the oxygen transmission pipe for the user to supplement oxygen.
