Product Description

Pressure swing adsorption oxygen production is to use zeolite molecular sieve as adsorbent, using the principle of pressure adsorption and pressure desorption to adsorb and release nitrogen from the air, so as to separate oxygen. Zeolite molecular sieve is a kind of spherical granular adsorbent which is processed by special pore type treatment process, and its surface and interior are full of micropores. The characteristics of its pore make it possible to realize the kinetic separation of O2 and N2. The separation of O2 and N2 by zeolites is based on the small difference of the kinetic diameters of the two gases. N2 has a faster diffusion rate in the micropores of zeolites, while O2 has a slower diffusion rate. The diffusion of water and CO2 in compressed air is similar to that of nitrogen. Finally, oxygen molecules are enriched from the adsorption tower.

Oxygen generators produce gaseous oxygen from compressed air on site and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid. Oxywise Oxygen Generators are available in 40 standard models with capacity ranging from 1 to 200 Nm3/hour at 90-99% purity. The design is made for round the clock 24/7 operation. Each generator is equipped with automatic start&stop function, enabling the generator to start and stop automatically according to the consumption. 

Oxygen generator incorporated with oxygen high pressure compressor for filling cylinders creates a system called Oxygen generating and filling station.  System consists of essentials such as air compressor, dryer, filtration etc. and standard features including molecular sieve protection, stainless steel piping and many more. 

2,The technical features of the oxygen generator after PSA are as follows

(1) Imported PLC control system and imported pneumatic angle seat valve with switching life up to 3 million times are adopted to ensure the continuous and reliable operation of the device.

(2) Imported PLC intelligent controller, easy to operate, stable operation, high degree of automation. Can choose touch screen control system, computer industrial control system.

(3) Reasonable internal components, uniform airflow distribution, reduce the impact of high-speed airflow.

(4) Special molecular sieve protection measures extend the service life of zeolite molecular sieve.

(5) The automatic interlock oxygen emptying device ensures the oxygen quality of the product.

(6) The operation of the whole machine can be: depending on the organic combination of advanced oxygen production process design, scientific gas distribution structure, adsorption tower with compound bed structure, unique molecular sieve filling process, unique molecular sieve protection measures and automatic compression compensation device of cylinder, it is conducive to the long-term use of oxygen molecular sieve.

4,Compressed air pretreatment
Because the molecular sieve in the main oxygen generator has high requirements for the quality of compressed air, and the gas temperature in the compressed air is high, and it contains a lot of water, certain dust and oil mist, so before the compressed air enters the oxygen generator, it must be treated with water, oil and dust removal, and this part of the equipment is mainly for this purpose.

The purification of compressed air is very important, please do not ignore this point! Because the quality of compressed air purification treatment is directly related to the service life of molecular sieve, which is directly related to the long-term effective use of oxygen generator.

Adsorption dryer or freezing dryer are mainly used to remove water from compressed air.

Different types of multi-stage filters with different filtering accuracy are mainly used for oil, water and dust removal of compressed air. Generally speaking, for oil-free air compressors, one to two-stage filters are required, mainly for dust removal and water removal; for oil-bearing air compressors, three to four stage filters are required, mainly for oil removal, water removal and dust removal.

In high humidity environment, it is recommended to install special blowdown tank to filter a large amount of water vapor in compressed air.
