Principle: The industrial production method of oxygen is to use the boiling point of liquid nitrogen to be lower than that of liquid oxygen to produce industrial oxygen.
Method: Firstly, the air is liquefied by low-temperature pressurization. Then adjust the temperature, utilize the boiling point of liquid nitrogen to be lower than that of liquid oxygen, the liquid nitrogen will be evaporated, and the rest will be mainly liquid oxygen. oxygen is a simple substance formed by oxygen element. Its chemical formula is O2. Its chemical properties are relatively active, and it can react with most elements. It is not very active at room temperature, and it is not easy to interact with many substances. However, it is very active at high temperatures and can directly combine with various elements, which is related to the electronegativity of oxygen atoms second only to fluorine.
The method of industrial oxygen production
Industrial oxygen production mainly uses physical methods to compress the air and then separate the gas through air separation equipment to obtain gases such as oxygen and nitrogen. The basic principle of industrial oxygen production equipment or oxygen generator is to use the oxygen and nitrogen in the air to separate, and to separate the nitrogen and oxygen in the air through the air separation unit, so as to obtain oxygen.
- Air compressor: mainly used to separate oxygen and nitrogen in the air. The working principle of the air compressor is to work by compressing the air, and then transport the high-pressure gas to the workplace, and separate the nitrogen and oxygen to obtain oxygen. At present, the most used compressor in our country is the automobile compressor, which is mainly used in automobile engines.
- The liquid oxygen storage tank mainly stores liquid oxygen in a pressure vessel, and then transports it to the place where oxygen production is needed through pipelines. This method can make the production process more efficient, and the operation is more simple and convenient. However, because this method consumes more energy, it is not widely used in our country.
- Pressure swing adsorption method: This method mainly uses pressure swing adsorption (PSA) technology to separate nitrogen and oxygen in the air. It can separate nitrogen and oxygen in the air. This method of oxygen production is available in many areas of our country.
- Cryogenic distillation: Cryogenic distillation refers to the removal and purification of molecules at low temperatures. It mainly extracts gases such as oxygen and nitrogen by removing water vapor in the air, and then performs rectification treatment on the obtained gas, and then obtains oxygen.
The principle of industrial oxygen production
Industrial oxygen generators are mainly produced by ionizing nitrogen and oxygen molecules in the air at low temperatures. These ionized molecules undergo a series of chemical changes to form oxygen molecules that can be absorbed. And the air containing nitrogen will produce oxygen after a series of treatments. The oxygen will be separated and then enter the corresponding storage tank. In this way, industrial oxygen production can be realized.
In the process of industrial oxygen production, in order to ensure the normal operation of the oxygen generator equipment, it is necessary to carry out regular inspection and maintenance. Among the more important maintenance tasks are:
- Regularly check whether each component is operating normally to ensure that the oxygengenerator equipment can operate normally;
- Regularly check the amount of oxygenin the storage tank and the storage of liquid oxygen;
- Regularly check whether there are leakage problems in pipelines and valves;
- Regularly check and clean the dust in the cryogenic storage tank of the oxygengenerator;
- Regularly clean and replace filters and filter elements, etc.
The above are the points that need to be paid attention to in the normal operation of industrial oxygen generating equipment. Only by maintaining the above aspects can we ensure the normal operation of industrial oxygen equipment and provide us with high-quality oxygen.
Industrial oxygen generating equipment is a relatively complex mechanical equipment, and there are many precautions that need to be paid attention to during its operation. If you do not operate in accordance with the correct operating specifications, it will bring a lot of adverse effects to the equipment, so we must strictly follow the requirements specified in the instructions during the operation.
