There are many brands of household oxygen generator in the market, different brands lead to different principles. The principle of use is of course different. Nowadays, the commonly used household oxygen generator is molecular sieve oxygen generator. So, what is the principle of molecular sieve oxygen generator? The principle of household oxygen generator is briefly introduced below.
The principle of household oxygen generator can be roughly divided into the following four types:
Principle of molecular sieve
Principle of polymer oxygen enriched membrane
Principle of electrolytic water
Principle of chemical reaction
Among the four principles mentioned above, only molecular sieve oxygen generator is relatively mature.
Working process of molecular sieve oxygen generator:
The process of molecular sieve oxygen generator can be divided into two towers. After the compressor pressurizes the raw materials air, the air pretreatment device removes dust, oil, water some solid impurities, then cools to room temperature. After processing, air enters the load the intake valve. In the adsorption tower of molecular sieve, the incoming air is removed carbon dioxide nitrogen, high purity oxygen is produced. After the adsorption tower reaches a certain saturation, close the inlet valve open the flushing valve. Then, the adsorption tower enters the washing stage. After flushing, close the flushing valve, then open the desorption valve to complete the desorption regeneration stages, use this principle to complete the cycle.
Characteristics of molecular sieve oxygen generator
1. Advanced principle: zeolite molecular sieve is used in molecular sieve oxygen generator, pressure swing adsorption technology (PSA) is used to strictly separate oxygen nitrogen in the air, other substances some harmful substances in the air are filtered out. In this way, high purity oxygen meeting the medical oxygen standard can be obtained in various places.
2. The production cost of oxygen is relatively low: it can be seen the above process that the molecular sieve oxygen generator is based on air, does need any additives other raw materials, has no residues pollution emissions, so it meets the environmental requirements.
3. Low power consumption, easy to use: as long as you plug in the power supply, you can produce oxygen. The operation is very simple, the oxygen concentration is stable the purity is high. The flow rate of oxygen can be adjusted properly can be used at any time without time limit. Oxygen can be supplied continuously for 24 hours.
