oxygen PSA

PSA oxygen generator

The 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. 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 this equipment plays an important role in the industrial industry.

 

 

JLOX-500 series high-efficiency oxygen generation molecular sieves are mainly used in pressure swing adsorption (PSA) oxygen generation devices. It has the advantages of high purity of oxygen production, high yield of oxygen production, fast adsorption rate and long service life. It is the best substitute for 5A (CaA) molecular sieve for oxygen production. JLOX-500 products are mainly used in PSA industrial oxygen production and medical center oxygen supply systems.

medical oxygen concentrator

PSA medical oxygen generators project

Pressure swing adsorption oxygen production equipment (also known as PSA oxygen production equipment) uses PSA special molecular sieve to selectively adsorb impurities such as nitrogen, carbon dioxide and water in the air under normal temperature and pressure conditions to obtain higher purity oxygen (93 %±2).

 

Household oxygen generators use molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The molecular sieve discharges the adsorbed nitrogen back into the ambient air when it is decompressed, and can adsorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process, and the molecular sieve is not consumed.
