Nitrogen making machine N2 producing machine
Introduction of PSA nitrogen generator
PSA nitrogen production principle: the main components in the air are nitrogen and oxygen. Therefore, adsorbents with different adsorption selectivity for hydrogen and oxygen can be selected, and scientific process can be designed to separate nitrogen and oxygen to produce nitrogen.
Both nitrogen and oxygen have quadrupole moments, but the quadrupole moment of nitrogen is much larger than that of oxygen, The adsorption capacity of oxygen in carbon molecular sieve is much stronger than that of nitrogen (the force between oxygen and ions on the surface of molecular sieve is strong. Therefore, when air passes through the adsorption bed equipped with carbon molecular sieve adsorbent under pressure, oxygen will be adsorbed by molecular sieve. Due to less adsorption, nitrogen will be enriched in the gas phase and flow out of the adsorption bed to separate oxygen and nitrogen to obtain nitrogen. When the molecular sieve adsorbs oxygen to near saturation, stop the air well to reduce the pressure of the adsorption bed, and the oxygen adsorbed by molecular sieve can be desorbed, and the molecular sieve will be recovered To regenerate and reuse. When more than two adsorption beds are switched in turn, nitrogen can be produced continuously.
Brief description of PSA nitrogen production process: each adsorption bed generally goes through the steps of adsorption, original pressure relief, decompression and regeneration, flushing and replacement, pressure equalization and pressure rise, and the operation is repeated periodically. At the same time, each adsorption bed is in different operation steps. Under the control of the computer, it is switched regularly to make several adsorption beds operate together and stagger each other in time steps, so that the pressure swing adsorption device can operate smoothly and continuously obtain product nitrogen.

Nitrogen is mainly used in packaging, sintering, annealing, reduction and storage of electronic products. It is mainly used in wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper tape, battery, electronic alloy materials, etc. According to different purposes, the requirements for nitrogen purity also vary. Generally, it is required not to be lower than 99.9% or higher. Some use 99.99% purity. Nitrogen purification equipment will be used in special industries to obtain high-quality nitrogen with purity greater than 99.995% and dew point lower than - 65 ºC. Nitrogen is also used to fill the voltage gas in circuit breakers, large-scale integrated circuits, protective gases for semiconductor and electrical appliances, laser drilling and other protective gases for electrical components.

The product adopts pressure swing adsorption nitrogen making technology, which can provide high-purity nitrogen with purity ≥ 98%. The produced nitrogen has high purity and extremely low content of oil, water and dust. It is suitable for filling nitrogen in tires of automobile service industry, military engineering vehicles and other industries. In developed countries such as the European Union and the United States, nitrogen filling of automobile tires has become a mandatory national standard. The product integrates air compression, nitrogen manufacturing, nitrogen pressurization, tire vacuum pumping and nitrogen filling.

Grain storage:
The green nitrogen filled grain storage technology is to fill the grain pile with high-purity nitrogen with a concentration of 9.5%, and replace the oxygen in the granary by using special equipment to keep the grain storage environment in a high nitrogen concentration, low oxygen concentration or oxygen free state for a long time. Under this gas concentration, the stored grain pests will suffocate and die due to hypoxia, and inhibit the reproduction of molds, so as to maintain the grain quality and ensure the safe storage of grain. Compared with the traditional fumigation technology, the green grain storage technology filled with nitrogen is safer and more green. It is a green grain storage method that integrates the advantages of killing insects, inhibiting mold, keeping fresh, storage, safety and green environmental protection, and is easy to implement.
