1. The pipe connection between each system shall be made by the user according to the site layout. 2. Floor area: The final equipment drawing shall prevail, and can be designed according to the user's actual position. 3. The main standards and specifications for the design, manufacture and inspection of this equipment project shall be implemented according to the current industry standards in China.The main components in the air are nitrogen and oxygen. Therefore, adsorbents with different adsorption selectivity for nitrogen and oxygen can be selected and appropriate technological process can be designed to separate nitrogen and oxygen to produce oxygen. Both nitrogen and oxygen have quadrupole moments, but nitrogen's quadrupole moment (0.31 A) is much larger than oxygen's (0.10 A), so nitrogen has A stronger adsorption capacity on zeolite molecular sieves than oxygen (nitrogen exerts A stronger force with ions on the surface of zeolite). Therefore, when air passes through the adsorption bed containing zeolite adsorbent under pressure, nitrogen is adsorbed by the zeolite, and oxygen is less absorbed, so it is enriched in the gas phase and flows out of the adsorption bed, making oxygen and nitrogen separate to obtain oxygen. When the molecular sieve adsorbs nitrogen to near saturation, the air is stopped and the pressure of the adsorption bed is reduced, the nitrogen adsorbed by the molecular sieve can be desorbed out, and the molecular sieve can be regenerated and reused. Oxygen can be produced continuously by switching between two or more adsorption beds. The boiling point of argon and oxygen is close to each other, so it is difficult to separate them, and they can be enriched together in the gas phase. Therefore, the psa oxygen production device usually can only obtain the concentration of 80% ~ 93% oxygen, compared with the concentration of 99.5% or more oxygen in the cryogenic air separation device, also known as oxygen-rich. Note: 1, the choice of pneumatic valve for Bolei or cover rice valve, the supporting cylinder for the import brand. 2. The control system is indoor. The control cable is connected from the equipment site to the operating room with a distance of less than 100m.General industrial air should be free of dust, chemical components, carbon monoxide, hydrocarbons and corrosive gases. dust content： Max. 5mg/m3 SO2: Max. 0.05mg/m3 NOX: Max. 0.05mg/m3 CO2: Max. 400ppm(vol.) In addition, the total amount of acidic gases such as hydrogen sulfide and hydrogen chloride in the air should be less than 10 parts per million.
