Product Description

Working principle of PSA nitrogen generator

Pressure Swing Adsorption (PSA) is a new type of gas adsorption and separation technology. It has the following advantages:

1. The product has high purity.
2. It can work at room temperature and common pressure (0.8mpa), without heating during bed regeneration, which is energy-saving and economical.
3.  The equipment is easy to operate and maintain.
4. Continuous cycle work, which can be fully automated.

PSA is a new type of gas adsorption and separation technology, which has the following advantages: High product purity. It can work at room temperature and common pressure (0.8mpa), without heating during bed regeneration, which is energy-saving and economical. The equipment is easy to operate and maintain. Continuous cycle work can be fully automated. With 5A zeolite molecular sieve adsorbent, a two-bed PSA device is used to separate oxygen enrichment from the air and separate O2 and N2 in the air to obtain nitrogen. Carbon molecular sieve is a kind of ink-colored particles which are specially processed from coal powder. Its surface is covered with numerous micropores. The principle of air separation depends on the different diffusion speeds of oxygen and nitrogen in the pores of carbon molecular sieve. The diffusion speed of oxygen into the pores of molecular sieve is much faster than the diffusion speed of nitrogen, so that oxygen molecules are adsorbed in the pores of carbon molecular sieve. , And nitrogen molecules are enriched in the gas phase. At the same time, the capacity of carbon molecular sieve to adsorb oxygen increases due to its pressure increase, and decreases due to its pressure drop. In this way, the carbon molecular sieve adsorbs when pressurized, and desorbs the oxygen component under reduced pressure, forming a cycle operation to achieve the purpose of separating air. Referred to as PSA Nitrogen.

Equipment installation diagram


Δ Advanced inequality pressure equalization process improves the utilization of carbon molecular sieve and directly reduces compressed air consumption
Δ Advanced internal structure, air flow deceleration, uniform distribution, reduce the impact force on the molecular sieve, and improve the service life of the molecular sieve
Δ We cooperate with well-known molecular sieve manufacturers at home and abroad, and can choose the most energy-saving and efficient ratio according to actual working conditions.
Δ  Reliable air source treatment accessories ensure the stable operation and service life of the equipment.
Δ  Adopting the blizzard filling method, the molecular sieve is filled more evenly and densely, the friction coefficient is reduced to the minimum, and the whole machine is improved
 Reliability of long-term operation.
Δ  It adopts Siemens PLC programmable controller for automatic control, one-key start without special personnel operation, and can be reserved for computer, mobile phone, etc.
Remote device connection, real-time observation of operation.
Δ  The valve is the key to the stable operation of the equipment, with fast opening and closing speed, low energy consumption, simple structure, good sealing performance, installation and maintenance
 Convenient and long service life.
Δ  Using a special spring compression device, when the molecular sieve in the adsorption tower decreases, it will automatically compensate to eliminate the problem of molecular sieve powdering.
 Extended service life.
Δ Automatic emptying of unqualified nitrogen/manual emptying (optional)
Δ The original components of famous brands at home and abroad are selected to ensure the operation of the equipment and the quality of nitrogen.Δ
