Specific introduction of chemical oxygen generator

A chemical oxygen generator is a device that can separate nitrogen from the air to generate high-concentration oxygen. Such devices are widely used in medical, industrial and scientific research, especially in the treatment of serious diseases such as respiratory failure. In this article, we will explore the principle, construction and application of chemical oxygen concentrators.

 

 

The principle of the chemical oxygen generator is based on the selective adsorption of nitrogen and oxygen molecules on molecular sieves. This molecular sieve is usually a porous material made of aluminosilicate or other substances, with a pore size of about 3 to 5 angstroms (1 angstrom = 10^-10 meters). When air passes through a molecular sieve, nitrogen molecules are more easily adsorbed on the surface of the molecular sieve than oxygen molecules. By adjusting parameters such as pressure and temperature, the residence time of nitrogen and oxygen molecules in the molecular sieve can be controlled, thereby realizing the separation of nitrogen and oxygen.

 

The chemical oxygen generator is mainly composed of the following parts: compressor, cooler, molecular sieve and oxygen storage tank. When the air enters the compressor, it is compressed into a high-pressure gas and flows through the cooler to cool it down. Next, the gas enters the molecular sieve, where nitrogen is adsorbed on the surface of the molecular sieve, while oxygen flows out through the molecular sieve. Finally, the oxygen is collected in an oxygen storage tank and supplied to equipment or patients that require high concentrations of oxygen.

 

Chemical oxygen concentrators have many advantages. First of all, it can achieve high-purity oxygen production, usually up to 90%. Secondly, compared with traditional liquid oxygen systems, chemical oxygen generators are more portable, space-saving, and easier to operate. In addition, in some special environments, such as extreme conditions such as mountains and deep seas, chemical oxygen generators can provide sufficient oxygen supply to ensure human life, health and safety.

 

The application fields of chemical oxygen generators are very wide. The most important application is in the medical field, for the treatment of respiratory failure, pneumonia, bronchitis and other diseases, and it can also be used as an oxygen source for operating rooms, ambulances, ambulance helicopters and other equipment. In addition, chemical oxygen generators are also widely used in industrial fields, such as the use of oxygen in glass, metal processing, chemical synthesis and other industries. In addition, chemical oxygen generators are also widely used in scientific research, such as material science, energy research and environmental protection and other fields.

 

 

A chemical oxygen generator is a device that can be used at home or other places where oxygen is needed, which can generate pure oxygen through a chemical reaction. The advantages include ease of use, high stability, simple operation and purer oxygen, but there are corresponding disadvantages, including the need to periodically replace the materials in the chemical reactor, the limited flow of oxygen produced, and the space occupied by larger models Many and noisy, and can not meet the needs of some patients with special conditions. Therefore, when choosing to use a chemical oxygen generator, you need to make a trade-off and choose according to your personal needs and specific circumstances.
