PSA Oxygen Generator
Process Principle
PSA oxygen generator uses clean compressed air as raw material and zeolite molecular sieve (ZMS) as sorbent, to produce oxygen gas with Pressure Swing Adsorption (PSA) technology in normal temperature. Comparing with oxygen, nitrogen is preferentially adsorbed by ZMS while at high pressure. ZMS releases adsorbed nitrogen at low pressure, which is called regeneration. The oil-free and dust-free compressed air enters one of the two adsorption towers filled with ZMS. Nitrogen is adsorbed ZMS micro pores and then retained and leaves oxygen as product gas. When ZMS in one tower is saturated with nitrogen, the adsorption tower is depressurized and ZMS is regenerated for next cycle. While one tower finishes the cycle, the other adsorption tower starts to work. With control on/off state of the pneumatic valve by PLC, to separate nitrogen and oxygen gas, and create continuous flow of oxygen with required purity.
Main Characters
1, Adopt human-based man-machine interface and intelligent control to make simple operation and supply qualified oxygen gas quickly.
2, High-efficiency filling of molecular sieve makes tighter, firmer and longer service life.
3, Adopt SIMENS and OMPON PLC controller and automatic switch system with German BURKERT pneumatic valves make the operation more stable.
4, Pressure, purity and flow are stable and adjustable can meet different requirements of customers.
5, Totally enclosed design, compact structure, nice appearance, and small occupation area.
