PSA Oxygen Generator Plays an Important Role in the Industrial Industry

  • 2021-05-21

PSA oxygen generator uses zeolite molecular sieve as 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 of O2 and N2 by zeolite molecular sieve is based on the small difference in the dynamic diameter of these 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.

 

For applications in the field of oxy-fuel 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 oxygen in the boiler combustion 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%.

 

Application in papermaking. 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 Chlorine-free bleached pulp production line; the new pulp production line requires 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.

 

Application in non-ferrous smelting, 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 sieve is the core of pressure swing adsorption. The excellent performance of molecular sieve and the length of service life have a direct effect on the stability of yield and purity.
