Oxygen Mechanism of Zeolite Molecular Sieve

Domestic oxygen generators have a variety of brands in the market, and their branding results in different principles. The principles of use are of course different. Nowadays, the most used home oxygen generator is the molecular sieve oxygen generator. What is the principle of molecular sieve oxygen generator? Here's a brief introduction to the principle of home oxygen generator.

The principle of home oxygen generator can be roughly divided into the following four types:
 
Molecular sieve principle
Polymer oxygen-enriched film principle
Electrolysis water principle
Chemical reaction oxygen production principle
     
Under the above four principles of oxygen generators, only molecular sieve oxygen generators are relatively mature at present, and are the only ones that meet international and national standards.
 
I. Workflow of molecular sieve oxygen generator:
    The process of molecular sieve oxygen generators can be divided into two towers. After the raw material and air are compressed by the compressor, the air pretreatment device is used to remove dust, oil, water, and some solid impurities, and then it is cooled to a normal temperature. After the treatment is completed, air enters from the intake valve to be installed. Molecular sieve adsorption tower, the incoming air is removed carbon dioxide and nitrogen, it is high purity oxygen. After the adsorption tower reaches a certain degree of saturation, the inlet valve is closed and the flush valve opens. The adsorption tower then enters the flushing stage. After the flushing is completed, the flush valve is closed, and then the desorption valve is opened, and the desorption regeneration phase is entered, and a cycle period is completed using this principle.

Second, the characteristics of molecular sieve oxygen generator
1. Advanced principle: Zeolite molecular sieves are used in molecular sieve oxygen generators. Pressure swing adsorption (PSA) is used to strictly separate the oxygen in the air from nitrogen and filter out other substances and some harmful substances in the air. In this way, high-purity oxygen conforming to the medical oxygen standard is obtained for use in various places.
2. Oxygen production costs are relatively low: As can be seen from the above process, molecular sieve oxygen generators use air as raw material, do not require any additives and other raw materials, and have no residue and pollution emissions, thus meeting the requirements of environmental protection.
3, small power consumption and easy to use: just plug in the power supply can generate oxygen, the operation is extremely simple, the oxygen concentration is very stable, and high purity. The flow rate of oxygen can be appropriately adjusted, ready for use at any time, without limitation of time and place, and oxygen can be continuously provided for 24 hours.
4. Safe and reliable: All gas paths of the molecular sieve oxygen generator are controlled by low-voltage system procedures, no radiation, no pollution, stable performance, low noise, and good protection for producers and environmental protection.
