The oxygen generator is a machine that produces oxygen. The principle is to use air separation technology to first compress the air with high density, and then use the difference in the condensation point of each component in the air to separate it from the gas or liquid at a constant temperature. After rectification, it is separated into oxygen and nitrogen. Due to the widespread use of oxygen and nitrogen, oxygen generators have been widely used. Especially in metallurgy, chemical industry, petroleum, national defense and other industries, it is most widely used.
1. Industrial
Oxygen Production Equipment The principle of industrial oxygen production equipment is to use air separation technology to compress air with high density and separate gas and liquid at a specific temperature. Industrial oxygen is usually obtained through this physical method.
2. Medical oxygen production equipment
All medical oxygen production equipment adopts the world's most advanced PSA (Pressure Swing Adsorption) air separation oxygen production technology. This is based on the difference in the adsorption capacity of the attractant (zeolite molecular sieve) for oxygen and nitrogen in the air to separate oxygen and nitrogen. When air enters the floor full of adsorbent, nitrogen has a strong adsorption capacity and is adsorbed, but does not adsorb oxygen, so a high concentration of oxygen can be obtained at the outlet end of the adsorption bed.
3. Household oxygen production equipment
The adsorption performance of molecular sieve is based on physical principles. A large-displacement oil-free compressor is used as a power source to separate nitrogen and oxygen in the air to obtain high-concentration oxygen. This oxygen production mechanism has fast oxygen speed and high oxygen concentration, and is suitable for oxygen therapy and oxygen health care for all kinds of people.
At present, the most common type of oxygen concentrator on the market is a household oxygen concentrator. This is because ordinary household oxygen generators are easy to use, easy to carry, and the oxygen content can reach medical levels.
Oxygen concentration
According to national regulations, the oxygen concentration of medical-grade oxygen generators should be stabilized at (90±3)%. That is, the oxygen concentration is stable between 87% and 93%. The oxygen concentration standard of the imported oxygen concentrator is slightly higher than the oxygen concentration standard stipulated by Japan. The oxygen concentration is generally stable at (93±3)%. That is, the oxygen concentration is 93% to 96%. Many oxygen generators are marked as medical grade, but the oxygen concentration is less than 50%, and as the use time increases, the oxygen concentration seems to be getting lower and lower. If the oxygen level cannot be stabilized between 87% and 90%, there is no point in treating respiratory diseases such as chronic obstructive pulmonary disease and emphysema.
