preparation
Medical oxygen generator is a new type of equipment based on pressure swing adsorption (PSA) technology to extract oxygen from the air. It uses molecular sieve physical adsorption and desorption technology to fill molecular sieve in the oxygen generator, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The specific working process is that the compressed air enters the adsorption tower through the switching valve after being purified by the air purification dryer. In the adsorption tower, nitrogen is adsorbed by molecular sieve, and oxygen is accumulated at the top of the adsorption tower and enters the oxygen storage tank, and then filtered by odor removal, dust removal filter and sterilization filter to obtain oxygen. The main components are: air tank, air compressor, cold dryer, oxygen generator, oxygen tank, etc.
Oxygen purity
The purity of bottled medical oxygen is ≥ 99.5% according to the national standard. Whether the oxygen generator adopts molecular sieve oxygen production or oxygen enriched membrane oxygen production; The purity of oxygen (about 90%) is lower than that of bottled medical oxygen.
purpose
The oxygen generator is suitable for small hospitals, clinics, health stations, sanatoriums, family oxygen therapy, sports training centers, plateau military stations and other oxygen consuming places in cities, villages, remote areas, mountainous areas and plateaus.
Oxygen enriched membrane oxygen generator
Oxygen enriched membrane oxygen generator this kind of oxygen generator adopts membrane oxygen production mode, through the filtration of nitrogen molecules in the air by the membrane, it can reach the concentration of 30% oxygen at the outlet, and has the advantages of small volume and small power consumption.
However, the machine using this oxygen production method produces 30% concentration of oxygen, which can be used for long-term oxygen therapy and health care, while the first aid required in the state of severe hypoxia can only use medical high concentration oxygen.
Molecular sieve oxygen generator
Molecular sieve oxygen generator generally adopts pressure adsorption and atmospheric pressure desorption (HP) method, and the same cycle process is carried out by two adsorption towers respectively.
(the process consists of two towers. After the feed air is pressurized by the compressor, the oil, dust and other solid impurities and water are removed through the air pretreatment device and cooled to normal temperature. The treated compressed air enters the adsorption tower equipped with molecular sieve through the inlet valve, the nitrogen and carbon dioxide in the air are adsorbed, and the outgoing gas is high-purity oxygen. When the adsorption tower reaches a certain saturation After, the inlet valve is closed, the flushing valve is opened, and the adsorption tower enters the flushing stage. After that, the flushing valve is closed, and the desorption valve is opened to enter the desorption regeneration stage, which completes a cycle)
Oxygen concentration: ≥ 90%
Chemical oxygen generator
Chemical oxygen generator adopts reasonable reagent formula and can be used in specific occasions. Indeed, it can meet the urgent needs of some consumers. However, due to the simple equipment, troublesome operation and high use cost, each oxygen inhalation needs to invest a certain cost, which can not be used continuously and many other defects, so it is not suitable for family oxygen therapy!
Electronic oxygen generator
Electronic oxygen generator is common in pharmacies. It adopts the process of oxidation and reduction of oxygen in the air in the solution, so it will not produce dangerous hydrogen like electrolytic water oxygen production. The whole machine runs quietly.
The product is strictly required in the process of handling and use. Tilting and inversion are not allowed, otherwise the solution will flow into the oxygen delivery pipe and spray into the nasal cavity, causing serious damage to the user.
At the same time, it is easy to produce other oxides in the process of oxygen production. The oxygen produced contains chemical substances. This kind of oxygen production method consumes a lot of power, and the service life of the electronic oxygen generator is difficult to exceed 1000 hours. In the process of use, it must ensure that the solution has an appropriate concentration, otherwise it cannot produce oxygen normally.
