What is the principle of household oxygen generators?
Oxygen is a colorless and odorless gas and an important substance on which the human body depends for survival. The application of oxygen is very wide, and all walks of life cannot do without oxygen, including the medical and health care industry. And household oxygen generators are suitable for the use of the majority of health care providers due to their convenient use and lightweight portability. Nowadays, there are various household oxygen generators on the market. Due to different principles of oxygen production, the usage characteristics of each household oxygen generator are also different. The principles of oxygen production of household oxygen generators include:
The first type: The principle of chemical reaction for oxygen production. Probably we all learned a lot of chemical knowledge about oxygen production in middle school. What the teacher taught us at that time was to use potassium permanganate for heating and decomposition, and use manganese dioxide as a catalyst for oxygen production. This is the chemical oxygen production we first came into contact with. There are also similar oxygen generators on the market now, which cannot be called oxygen generators. Because it is just a container with an inhalation function, and it is necessary to continuously buy reagents to produce oxygen. The biggest advantage of this kind of oxygen generator is that it is cheap when bought for the first time, but the subsequent cost is expensive, and only 15 minutes of inhalation can be done each time the reagent is put. In addition, it is chemical oxygen production, and there will be more or less some side effects of generating other gases. However, its oxygen concentration is very high, which can reach 90%. For those who need first aid, oxygen can be replenished in time. But due to the simple equipment, troublesome operation, high usage cost, and the need to invest a certain amount of money for each oxygen inhalation and cannot be used continuously, and many other defects are not suitable for home oxygen therapy.
The second type: The principle of electrolyzing water. Electrolyzing water, as the name suggests, is to extract oxygen by electrolyzing water with electricity. There must be an electrode decomposition device inside, and water needs to be continuously added. This kind of oxygen generator is expensive, but the service life is shorter, and the machine cannot be tilted and cannot be moved casually. The power consumption is also very large, otherwise it will be damaged and the stability is poor. This kind of oxygen production method is generally rarely used in household oxygen generators, and is used more in industry.
The third type: The principle of oxygen-enriched membrane. The oxygen-enriched membrane is based on the principle of selective permeation of organic polymer membranes. By using the characteristic that oxygen molecules in the air can pass through preferentially by the oxygen-enriched membrane, oxygen is制取 through physical devices for centralized concentration. The oxygen production technology of the oxygen generator based on the oxygen-enriched membrane is relatively simple and the technical level is low. However, the oxygen produced by the machine using this oxygen production method is about 30% concentration, which can be used for long-term oxygen therapy and health care, while first aid required in a severe oxygen-deficient state can only use medical high-concentration oxygen.
The fourth type: The principle of molecular sieve. This kind of oxygen generator is the currently popular oxygen production technology, and the oxygen production effect depends on the quality of the molecular sieve and the compressor. A molecular sieve is a particle with many pores of different diameters, and these pores are only a few microns, so it is possible to choose which molecules can pass through and which cannot according to the size of molecules in the air. This oxygen production technology is to inhale oxygen from the air by this physical method of the diameter of molecules, and there is completely no side effect. This kind of oxygen generator can be used for physical therapy and health care. The oxygen concentration is generally about 30%-90%, and the oxygen concentration and flow can be adjusted. It is also more convenient to use, and the appropriate oxygen concentration can be selected according to the improvement of one's own condition.
