Nitrogen making machine is based on the principle of pressure swing adsorption, first of all, the air is compressed by the air compressor to the required pressure into the air storage tank, so that the air pressure change is relatively stable and relieved into static pressure, by the air storage tank to remove a large number of liquid water and oil in the compressed air, and then through the air treatment system cold dry machine, four-stage filtration to remove the water, oil, dust in the compressed air. The raw air is changed into clean and stable compressed air, and then through PSA pressure swing adsorption nitrogen production device, more than 99.5% pure nitrogen is produced. Using high-quality carbon molecular sieve as the adsorbent, in a certain mechanical effect, the diffusion rate of oxygen in the carbon molecular sieve micropores is much higher than that of nitrogen, when the adsorption does not reach equilibrium, nitrogen is enriched in the gas phase to form finished nitrogen. Then reduce the pressure to normal pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally, two adsorption towers are set up in the system, one tower is adsorbed to produce nitrogen, and the other tower is desorption and regeneration, which is automatically controlled by PLC program to make the two towers work alternately to achieve the purpose of continuous production of high-quality nitrogen. Under pressure, the purified and dry compressed air is subjected to pressure adsorption and decompression desorption in the adsorber.

The company can provide output from 3-3000Nm3/h, purity from 95% to 99.9995% of nitrogen, can be widely used in chemical, electronics, textile, coal, oil, natural gas, medicine, food, glass, machinery, powder metallurgy, magnetic materials and other industries.
