Introduction: The HTN pressure swing adsorption nitrogen generator is designed using the PSA pressure swing adsorption principle. The high-quality carbon molecular sieve is used as the adsorbent to obtain a steady stream of nitrogen under a certain pressure. Nitrogen generators can be widely used in electronics industry, heat treatment, food industry, coal industry, chemical industry, natural gas industry, cable industry, metallurgical industry, rubber industry, aerospace industry, etc. In response to the different requirements for the use of nitrogen by different users in different industries, Hunter Gas provides personalized and professional nitrogen production equipment and installation and application solutions, and provides after-sales service during the operation of the equipment, fully meeting the gas requirements of different users, and quickly Solve user problems and ensure long-term, stable and reliable operation of nitrogen-making equipment.

Working principle: Pressure swing adsorption (PSA gas separation technology for short) uses high-quality carbon molecular sieves as adsorbents to produce nitrogen from the air under a certain pressure. The cleanliness from the air buffer tank Compressed air enters the pressure swing adsorption separation system filled with adsorbent in the adsorption tower, where pressure adsorption and decompression desorption are carried out in the adsorber. Due to the kinetic effect, the diffusion rate of oxygen in the micropores of the carbon molecular sieve is much greater than that of nitrogen. When the adsorption has not reached equilibrium, the nitrogen is enriched in the gas phase to form the finished nitrogen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to achieve regeneration. Generally, two adsorptions are set in the system One tower is used to adsorb nitrogen and the other is desorption and regeneration. The two towers are automatically controlled by PLC program to make the two towers work alternately to achieve continuous production of nitrogen with a purity of ≥99.99%. The output is 2000Nm3/h, and the nitrogen dew point is at normal pressure. -40°C.
