Today let’s talk about how the molecular sieve oxygen generator
produces oxygen. Many customers who plan to buy an oxygen concentrator still do not understand the oxygen production principle of the molecular sieve oxygen concentrator. They think that water needs to be added to produce oxygen. Some customers even think that adding water can only produce oxygen for 99 minutes at a time.
In fact, molecular sieve oxygen generators, that is, PSA oxygen generators, do not need to add water during the oxygen process. The principle of the oxygen generator is to separate oxygen and nitrogen in the air through molecular sieves through the action of a compressor. . The mechanism of action is that oxygen
and nitrogen have different adsorption capacities on the molecular sieve surface, and nitrogen is easier to adsorb. Therefore, the oxygen production itself does not require any additives, let alone water.
The reason for the misunderstanding may be that many customers see a bottle filled with water in front of the oxygen concentrator, called a humidification bottle. When inhaling oxygen, distilled water or purified water must be added to the humidification bottle. The function of the humidification bottle is to humidify the oxygen gas coming out of the oxygen generator. Because the air entering the oxygen generator must be filtered by a triple filtration system to filter out impurities in the air, such as dust, bacteria, water vapor, etc., because molecular sieves are relatively delicate, water vapor or dust
Attaching to molecular sieves will seriously affect their lifespan. Because the filtration is very clean, the oxygen coming out of the oxygen generator is very dry. Inhaling it directly into the human body will cause irritation to the respiratory tract, so it must be humidified through a humidification bottle first.
Another reason for misunderstanding is that there is indeed a type of oxygen concentrator on the market that requires adding water during the oxygen production process. That is the famous Oxylide oxygen concentrator. This kind of oxygen generator is very cheap, only one or two hundred yuan. Its principle of oxygen production
is the reaction of potassium permanganate and water to generate potassium manganate, manganese dioxide and oxygen. During the reaction Water is required, but the cost of subsequent use of this type of oxygen concentrator is high. Each time it is used, a medicine pack needs to be added, and one pack of medicine can only produce oxygen for about 20 minutes. It is used for daily health care. However, it cannot be used for patients and elderly people.
