Detailed Explanation of the Principles, Characteristics, and Applications of Industrial Oxygen Generators

     Industrial Oxygen GeneratorIndustrial oxygen generators are used in industrial settings. They separate nitrogen and oxygen using the principle that nitrogen and oxygen have different diffusion rates in the micropores of zeolite molecular sieves. Relatively pure oxygen is obtained through the evaporation of liquid nitrogen. They feature convenient installation, long service life, economical oxygen supply, and online oxygen concentration monitoring and adjustment. They are widely used in non-ferrous metallurgy, papermaking, and oxygen-enriched combustion industries. Let's take a look at the principles, characteristics, and applications of industrial oxygen generators.

　  What is the principle of an industrial oxygen generator?

　　The industrial production method of oxygen utilizes the fact that the boiling point of liquid nitrogen is lower than that of liquid oxygen. The method used is a physical method. Air is liquefied under low temperature and high pressure. Then, the temperature is adjusted, and the liquid nitrogen evaporates because its boiling point is lower than that of liquid oxygen, leaving mainly liquid oxygen.

　　Industrial oxygen generators use zeolite molecular sieves as adsorbents. They utilize the principle of pressure adsorption and pressure swing adsorption to adsorb and release oxygen from the air, thereby separating oxygen. Due to slight differences in the kinetic diameters of nitrogen and oxygen, nitrogen molecules diffuse faster in the micropores of the zeolite molecular sieve than oxygen molecules. Therefore, oxygen and nitrogen can be separated to produce relatively pure oxygen.

　　What are the characteristics of industrial oxygen generators?

　　1. More economical compared to other oxygen supply methods. The process used by industrial oxygen generators is a simple oxygen production method, using air as a raw material and only consuming the electricity of the air compressor. It has the advantages of low operating cost, low energy consumption, and high efficiency.

　　2. The zeolite molecular sieve uses a "snowstorm" method for loading, ensuring uniform distribution without dead angles and preventing pulverization; the adsorption tower uses a multi-stage airflow distribution device and an automatic pressure-tightening device; the adsorption performance of the zeolite molecular sieve is maintained in a compressed state, and no fluidization occurs during adsorption, effectively extending the service life of the zeolite molecular sieve.

　　3. Provides an ideal purity selection range. Oxygen purity is easily adjustable, and it can be adjusted arbitrarily between 21%-93.2% according to user needs.

　　What are the main applications of industrial oxygen generators?

　　1. Non-ferrous metallurgy industry

　　With the adjustment of the national industrial structure, non-ferrous smelting has developed rapidly in recent years. In the oxygen bottom-blowing smelting of lead, copper, zinc, and antimony, and in the oxygen leaching smelting of gold and nickel, many manufacturers have begun to use industrial oxygen generators.

　　2. Papermaking industry

　　With the upgrading of national environmental protection requirements for papermaking processes, the requirements for pulp (including wood pulp, reed pulp, and bamboo pulp) are also becoming increasingly stringent. Pulp production lines using chlorine bleaching should be gradually transformed into chlorine-free bleached pulp production lines. New pulp production lines require chlorine-free bleaching processes. Pulp bleaching requires high-purity oxygen. The oxygen produced by pressure swing adsorption oxygen generators meets the requirements and is economical and environmentally friendly.
