What’s the application of Molecular Sieves in Industrial Oxygen generators?
Industrial oxygen generators are indispensable important equipment in modern production. Their main function is to separate oxygen and nitrogen in the air to obtain high-purity oxygen. In industrial oxygen generators, molecular sieves are one of the core materials for achieving this separation process.
一、The structure and principle of molecular sieves
Molecular sieves are highly porous substances, with pore sizes generally ranging from 1 to 10 nanometers. The pore size of molecular sieves can be adjusted within a certain range, which enables it to screen the size of molecules. Only small molecules can pass through the sieve pores. The commonly used molecular sieve materials mainly include zeolite, aluminosilicate, calcium sodium water glass, etc.
In industrial oxygen generators, molecular sieves mainly separate oxygen molecules and nitrogen molecules by taking advantage of their different sizes through physical adsorption and desorption techniques. Specifically, the air first enters the pretreatment system to remove water, oil and impurities, etc., and then is compressed and enters the molecular sieve device. Inside a molecular sieve device, there are usually two layers of separation screens. The first layer is used to filter out impurities such as organic substances, while the second layer is used for the separation of oxygen and nitrogen. In the second separation layer, the molecular sieve sieves oxygen molecules and nitrogen molecules, capturing oxygen molecules on the sieve layer while retaining nitrogen molecules within it. At this point, pure oxygen can be obtained from the other side.
二、The Application of Molecular Sieves
The application of molecular sieves in industrial oxygen generators mainly achieves the preparation of high-purity oxygen through their separation effect on oxygen and nitrogen. Industrial oxygen generators usually have high requirements for oxygen production and purity, which demands that molecular sieves must have efficient, stable and reliable separation performance. The following will introduce in detail the application of molecular sieves in industrial oxygen generators:
1.Improve the purity of oxygen
In industrial oxygen generators, the main function of molecular sieves is to separate oxygen and nitrogen to achieve the preparation of high-purity oxygen. The screening efficiency and separation efficiency of molecular sieves play a crucial role in improving the purity of oxygen. At present, the screening accuracy of molecular sieve materials has reached below 0.1nm, which can achieve efficient separation of oxygen and nitrogen and improve the purity of oxygen.
2.Increase oxygen production
The application of molecular sieves can also increase the oxygen output of industrial oxygen generators. Under normal circumstances, the molecular sieve materials used in industrial oxygen generators have a high adsorption capacity and a fast adsorption speed, which can effectively increase the oxygen output and enhance the production efficiency of industrial oxygen generators.
3.Save energy
Molecular sieves can also save energy in the oxygen production process through their separation effect on oxygen and nitrogen. Compared with traditional separation methods, molecular sieves can achieve more efficient separation of oxygen and nitrogen, reduce energy loss in the oxygen production process, and improve the energy utilization rate of industrial oxygen generators.
三、The advantages of molecular sieves
The application of molecular sieves in industrial oxygen generators has the following advantages:
1.Efficient, stable and reliable
Industrial oxygen generators need to have efficient, stable and reliable performance to meet production requirements. Molecular sieves have a high porosity and efficient separation performance, which can effectively separate oxygen and nitrogen, ensuring the purity and output of oxygen.
2.Energy conservation and environmental protection
Molecular sieves do not require chemical reagents. They only need compressed air to separate oxygen and nitrogen, without consuming a large amount of chemical reagents and energy. Therefore, they have the advantages of energy conservation and environmental protection.
3.Long service life and easy maintenance
Molecular sieves have the characteristics of long service life and easy maintenance, and can maintain stable separation performance for a relatively long time. Moreover, the maintenance cost of molecular sieves is relatively low. They only require regular cleaning and replacement, which significantly reduces the operating cost of the equipment.
In conclusion, as one of the core components of industrial oxygen generators, molecular sieves have advantages such as high efficiency, stability, reliability, energy conservation and environmental protection, and can achieve the preparation of high-purity oxygen and the separation of oxygen and nitrogen. With the continuous development of industrial technology, the application prospects of molecular sieves in industrial oxygen generators will be even broader.
