China High Purity Oxygen Gas Generator for Medical

Oxygen Generator
1. High Purity
2. Excellent Energy-Saving
3. Steady-going, Long life-span
4. Highly Automated Operation
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.
Technical Features
1).Full Automation
All systems are designed for un-attended operation and automatic Oxygen demand adjustment.
2).Lower Space Requirement
The design and Instrument makes the plant size very compact,assembly on skids,prefabricated from factory.
3).Fast Start-up
Start-up time is only 5 minutes to get desired Oxygen purity.So these units can be switched ON&OFF as per Oxygen demand changes.
4).High Reliabiity
Very reliable for continuous and steady operation with constant Oxygen purity.Plant availability time is better than 99% always.
5).Molecular Sieves life
Expected Molecular sieves life is around 15-years i.e. whole life time of Oxygen plant.So no replacement costs.
6).Adjustable
By altering flow,you can deliver nitrogen with precisely the right purity
Oxygen generator applications
smelting of nonferrous metal,chemical production, cement production, paper pulp and paper making, glass kiln, solid waste incineration, sewage treatment, waste gas treatment, etc. industries.
