Product Details

Principle of medical molecular sieve oxygen generator:

    Pressure swing adsorption (PSA) medical oxygen generator is an automatic equipment for separating oxygen from the air by adsorbing and releasing nitrogen from the air by using zeolite molecular sieve as adsorbent.

    Zeolite molecular sieve is a spherical granular adsorbent which is processed by a special pore processing process and has micropores on its surface and inside. It is white. Its pore shape makes it possible to achieve the dynamic separation of O2 and N2. The separation of O2 and N2 by zeolite molecular sieves is based on the small difference in the kinetic diameter of the two gases. The N2 molecule has a faster diffusion rate in the micropores of the zeolite molecular sieve, and the O2 molecule has a slower diffusion rate. The diffusion of water and CO2 in the compressed air is not much different from that of nitrogen, and finally the oxygen molecules are enriched from the adsorption tower.



Comparison of medical molecular sieve oxygen generator and traditional oxygen supply

Compared with traditional liquid oxygen and bottled oxygen supply, medical molecular sieve oxygen generator has obvious advantages such as safety, environmental protection, economy and convenience, so it has become the best choice for oxygen supply in modern hospitals.

1Safety

The working pressure of liquid oxygen storage tank is 1.6MPa, the working temperature is -183°C, belonging to medium pressure and ultra-low temperature equipment; the pressure of bottled oxygen is 150MPa, which belongs to high-pressure equipment; the working temperature of oxygen generator is 540°C, working pressure1.0 MPa, belonging to low pressure, normal temperature equipment. Therefore, among various oxygen supply modes, the safety of liquid oxygen is the lowest, and the safety of the oxygen generator is optimal.

The liquid oxygen storage tank is double-layered, and the interlayer is filled with an insulating material (perlite or magnesium carbonate) and then pumped to a vacuum. The liquid oxygen storage tank stores a large amount of liquid oxygen, and the temperature of the liquid oxygen is extremely low (-183 ° C). The vaporization ratio of liquid oxygen is about 1:800, which means that if one cubic meter of liquid oxygen is vaporized instantaneously, the volume will rise to more than 800 cubic meters, and the pressure of Peng is enough to break the bone body.

At the same time, at ultra-low temperatures, everything, including steel, becomes brittle and vulnerable. In addition, liquid oxygen has strong oxidizing properties, and once it leaks, it can cause frostbite and deoxidation of the human body. It is extremely corrosive and the consequences are very serious.

Oxygen is also a powerful gas. It is dangerous to place a liquid oxygen tank in a densely populated hospital. It is easy to leak during liquid oxygen transportation and dispensing. Even if a small amount of grease is encountered, fire may occur. There is a safety hazard and its strong combustion-supporting performance is increased. The burden of fire. Therefore, the liquid oxygen system needs regular strong inspection. If the rupture disk explosion or the exhaust valve on the liquid oxygen tank starts to vent, the vacuum of the interlayer of the liquid oxygen tank is destroyed, and the vacuum should be re-examined after inspection. The insulation performance of the tank is generally about two years. Once the vacuum is lowered or the insulation material is damp, the heat preservation property is subject to the threat. The user has to increase the vacuum pump to continuously vacuum the tank interlayer to maintain its insulation performance.

The medical molecular sieve oxygen generator works under normal temperature and low pressure, and there is no unsafe factor in principle. It is the safest among various oxygen supply methods. The oxygen generator system has an automatic monitoring system. If there is an unsafe factor, the system can automatically alarm and automatically shut down the system when needed. At the same time, the oxygen generator is generally equipped with a backup bus oxygen source to ensure the supply of oxygen in the event of power outage, shutdown or oxygen consumption for a certain period of time suddenly exceeding the oxygen production capacity of the oxygen generator.

2Environmental Friendly

The oxygen generator uses air as a raw material to separate oxygen from the air at the use site by physical means, and no pollutants are generated.

3Convenience

Liquid oxygen needs frequent filling and needs long-distance transportation. The oxygen generator is on-site oxygen production. Therefore, the oxygen supply of the oxygen generator is much more convenient than that of liquid oxygen, and it is not affected by weather and traffic.

The liquid oxygen storage tank needs to be filled 1 or 2 times a week. The operation requirements are very high when filling, and the operator needs to be certified to work, the output pressure is detected every day, and the equipment is regularly checked and repaired. The oxygen program is cumbersome. It is necessary to have a professional manufacturer's low-temperature tanker to deliver liquid oxygen in order to use it. Its use must rely on outsourcing, without the autonomy of oxygen use. Each time the filling is done, the liquid oxygen supplier charges the total capacity of the liquid oxygen storage tank, regardless of the actual amount of the filling, regardless of how much liquid oxygen remains in the tank, according to the filling of the whole tank. Therefore, hospitals that use liquid oxygen often face such troubles. If the manufacturer is informed to fill the liquid oxygen, there is still a lot of liquid oxygen in the tank, which will cost a lot of money. If the notice is late, there is a risk of gas shortage.

The oxygen generator realizes the local oxygen production, establishes its own independent oxygen station, does not need oxygen transport, is not restricted by the region, and automatically produces oxygen according to the needs, free from human factors, weather, traffic and other factors. And the equipment realizes automatic operation, no need to adjust frequently, the operation is safe, simple and convenient; without other auxiliary equipment, qualified medical oxygen can directly enter the pipeline system, making the management of the hospital more scientific and modern.

4Economical

Among all oxygen supply methods, the cost of oxygen supply to the oxygen generator is the lowest, and economics is one of the largest and most prominent advantages of oxygen supply.
