Medical oxygen machine, commonly used as pressure swing adsorption oxygen machine, adopts pressure swing adsorption technology to produce oxygen, can extract oxygen from air. The medical oxygen machine is filled with molecular sieve, and the surface area of each gram of molecular sieve can reach 800-1000m2/g. Under pressure, the physical adsorption technology and desorption technology of molecular sieve are used to absorb nitrogen in the air, and the oxygen not adsorbed will be collected. Through purification treatment, oxygen with high purity can be obtained. With the molecular sieve depressurized, the nitrogen previously adsorbed will be discharged back into the air. When pressure is again applied, nitrogen can be adsorbed for oxygen production. Therefore, the medical oxygen generator can realize periodic circulation oxygen production, which is a dynamic process.
The oxygen production flow of medical oxygen generator (PSA oxygen generator) is shown in the figure. The oxygen raw material is air. After filtration (remove oil, dust, water, solid impurities, etc.) of air, the compressed high-pressure air enters the adsorption tower for adsorption and separation. The adsorption tower is equipped with molecular sieve, and nitrogen and carbon dioxide will be divided The gas from the adsorption tower is the oxygen with high purity, which can be used as medical oxygen. The separated oxygen enters the air storage tank through a one-way valve, and then flows out to the user through the flowmeter and humidification bottle after pressure reduction by the pressure reducing valve; the other part of oxygen reverses the desorption adsorber, and the desorption nitrogen is discharged through the muffler
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.
In order to get access easily for the O2 continuously for the hospital, an onsite PSA oxygen generation system is a fast response and convenient solution.
A PSA oxygen generation system for ONLY
one-time investment, costing merely for the simply maintain and the electricity fee to generate the O2 gas by yourself.
The outlet pure O2 gas can supply both of the pipes and the cylinder filling applications.
1.What is the purity of the PSA oxygen machine?
The average PSA oxygen machine is 90%-93% pure.
Our PSA oxygen machine can reach 95%,98%,up to 99%
The daily maintenance of the oxygen machine is relatively simple:
A,Air compressor to regular maintenance, air filtration, oil concerns, oil in accordance with the instructions to regularly call manufacturers to replace.
