Briefly describe the significance of PSA oxygen generator in industry

Back Source: 超级管理员 Date: 2021.07.23

Do you know the industrial significance of PSA oxygen generator?


PSA oxygen generator uses zeolite molecular sieve as the adsorbent, and uses the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating oxygen from the automatic equipment.


The separation effect of zeolite molecular sieve on O2 and N2 is based on the small difference in the dynamic diameter of the two gases. N2 molecules have a faster diffusion rate in the micropores of zeolite molecular sieve, and O2 molecules have a slower diffusion rate. With the continuous acceleration of the industrialization process, the market demand for PSA oxygen generators continues to increase, and the equipment plays an important role in the industrial industry.


1. Oxygen-enriched combustion


The oxygen content in the air is ≤21%. The combustion of fuel in industrial boilers and industrial kilns also works under this air content. Practice has shown that when the amount of gas and oxygen burned by the boiler reaches more than 25%, the energy saving can be as high as 20%; the boiler start-up heating time is shortened by 1/2-2/3. The oxygen enrichment is the application of physical methods to collect the oxygen in the air, so that the oxygen enrichment content in the collected gas is 25%-30%.

2. Papermaking field


With the country's upgrading of environmental protection requirements for papermaking processes, the requirements for white pulp (including wood pulp, reed pulp, and bamboo pulp) have become higher and higher. The original chlorine bleached pulp production line should be gradually transformed into a chlorine-free bleached pulp production line; The new pulp production line requires the use of a chlorine-free bleaching process, and pulp bleaching does not require high-purity oxygen. The oxygen produced by the pressure swing adsorption oxygen generator meets the requirements, which is economical and environmentally friendly.


3. Non-ferrous smelting field


With the adjustment of the national industrial structure, non-ferrous smelting has developed rapidly in recent years. Many manufacturers in smelters that use oxygen bottom blowing lead, copper, zinc, and antimony smelting processes and oxygen leaching gold and nickel smelting processes have begun to use pressure swing adsorption oxygen generators. The market for the use of PSA oxygen generators has been expanded.


The quality of molecular sieve used in PSA oxygen generator occupies a major position. Molecular sieves are the core of pressure swing adsorption. The superior performance and service life of molecular sieves have a direct impact on the stability of yield and purity.
