What is the method of Industrial Oxygen Generator?
The Industrial Oxygen Generator, as its name implies, is a device for producing oxygen in industrial production. Industrial Oxygen Generator is roughly composed of air compressor, pre-cooling device, purification device, air separation tower, etc.
Generally, the method of producing oxygen by decomposition of hydrogen peroxide or potassium permanganate is commonly used in the laboratory. It has the characteristics of fast reaction, simple operation, and easy collection of the industrial oxygen concentrator, but the cost is high, and mass production is not possible. It can only be used in the laboratory in. Industrial production needs to consider whether the raw material oxygen generator is of a good brand, whether it is easy to obtain, whether the price is cheap, whether the cost is low, whether it can be mass-produced, and the impact on the environment. The air contains about 21% oxygen, which is a cheap and easily available raw material for making oxygen.
1. Air freezing separation method
The main components in the air are oxygen and nitrogen. Using the different boiling points of oxygen and nitrogen, the preparation of oxygen from air is called air separation. First, the air is pre-cooled and purified (to remove a small amount of moisture, carbon dioxide, acetylene, hydrocarbons and other gases and dust and other impurities in the air), and then compressed and cooled to make it into the top ten brands of industrial oxygen generators as liquid air.
Then, using the difference in the boiling points of oxygen and nitrogen, the liquid air is evaporated and condensed many times in the rectification tower to separate the oxygen and nitrogen to obtain pure oxygen (up to 99.6% purity) and pure nitrogen ( Can reach a purity of 99.9%). If you add some additional devices, you can also extract argon, neon, helium, krypton, xenon and other rare inert gases in the air with very little content. The oxygen produced by the air separation device is compressed by a compressor, and finally the compressed oxygen is stored in high-pressure steel cylinders, or directly transported to factories and workshops through pipelines for use.
2. Molecular sieve oxygen production method (adsorption method)
Taking advantage of the fact that nitrogen molecules are larger than oxygen molecules, a special molecular sieve is used to separate the oxygen in the air. First, the compressor is used to force the dry air through the molecular sieve into the vacuumized adsorber. The nitrogen molecules in the air are adsorbed by the molecular sieve, and the oxygen enters the adsorber. When the oxygen in the adsorber reaches a certain amount (the pressure reaches a certain level) ), you can open the oxygen valve to release oxygen.
After a period of time, the nitrogen adsorbed by the molecular sieve gradually increases, the adsorption capacity is weakened, and the purity of the oxygen produced decreases. It is necessary to use a vacuum pump to extract the nitrogen adsorbed on the molecular sieve, and then repeat the above process. This method of producing oxygen is also called adsorption. A small PSA oxygen generator using adsorption method to produce oxygen has been developed, which is convenient for household use.
The above is about the preparation methods and skills of PSA oxygen generator. It needs to be used with some professional equipment. You can choose YG PSA oxygen generator, compressor and other oxygen generation equipment.
