According to the principle of pressure swing adsorption, the small nitrogen generator uses high-quality carbon molecular sieve as adsorbent
to extract nitrogen from the air under certain pressure. The purified and dried compressed air is adsorbed under pressure and desorbed under pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of oxygen
in the micropores of carbon molecular sieve is much higher than that of nitrogen. Oxygen is preferentially adsorbed by carbon molecular sieve, and nitrogen is enriched in the gas phase to form finished nitrogen. After decompression
to atmospheric pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to realize regeneration. Qi.

Product features of small nitrogen generator
1. The operation cost is low, the raw air is taken from nature, and nitrogen can be generated only by providing compressed air and power. The equipment has low energy consumption and low operation cost.
2. The whole machine operates reliably and the nitrogen purity is easy to adjust. The purity of nitrogen is only affected by nitrogen emissions. The purity of common nitrogen is adjusted between 95% and 99.99%; The nitrogen purification unit can be installed in
Adjust between 99.99% and 99.9995%.
3. Stable continuous production, high degree of equipment automation, fast gas production and unattended. Just press the button to start and shut down. Nitrogen can be generated within 10 to 15 minutes after start-up.
4. The advanced control system adopts Mitsubishi PLC control system of Japan and Baode pneumatic valve of Germany, and the switching life is 3 million times. It is efficient and durable, which can ensure the continuous and reliable operation of the equipment.
5. The nitrogen quality of small nitrogen generator is stable, and the special cylinder compression device avoids the pulverization of molecular sieve caused by the impact of high-pressure air flow. The adsorption process with adjustable nitrogen flow and pressure is equipped with automatic interlock protection
Empty device can ensure the purity of nitrogen gas and long-term pressure stability.
6. The equipment has small floor area, simple equipment process, small equipment structure, small floor area and strong equipment adaptability.

The process flow of small nitrogen generator is that the air enters the polymer membrane filter after being compressed and

filtered by the compressor, resulting in different relative permeation rates of different gases in the membrane.
Under the action of the pressure difference on both sides of the membrane, gases with fast penetration rate such as water,

hydrogen, helium, hydrogen sulfide and carbon dioxide are enriched on the penetration side of the membrane, while gases with

slow penetration rate such as methane, nitrogen, carbon monoxide and argon are intercepted and enriched on the penetration

side of the membrane, so as to achieve the purpose of mixed gas separation.
