2,Brief introduction of process principle:Pressure swing adsorption nitrogen production is based on clean, dry compressed air as raw material, and uses a high-efficiency and highly selective solid adsorbent (carbon molecular sieve) to selectively adsorb nitrogen and oxygen to reduce the nitrogen and oxygen in the air. separate from. Carbon molecular sieves are non-polar molecules and preferentially adsorb oxygen. The separation effect of carbon molecular sieve on oxygen and nitrogen is mainly based on the different diffusion rates of these two gases on the surface of carbon molecular sieve. Gas with a smaller diameter (oxygen) diffuses faster, and more enters the solid phase of the molecular sieve. Gas with a larger diameter ( Nitrogen) diffuses slowly and less enters the solid phase of molecular sieve. In this way, nitrogen-rich components can be obtained in the gas phase. After a period of time, the adsorption of oxygen by molecular sieve reaches equilibrium. According to the different characteristics of carbon molecular sieve for adsorbing gas under different pressures, the pressure is reduced to release carbon molecular sieve from adsorbing oxygen. This process is called regeneration. The PSA method usually uses two towers in parallel, alternately performing pressure adsorption and decompression regeneration, so as to obtain a continuous nitrogen stream.
3,Main features of PSA nitrogen generator·
Provide maximum commercial value1. The filling and compaction of molecular sieve is done in a professional environment in a professional way.
The density is greater and the efficiency is higher.
2. The design of process and structure is optimized, and the system can exert its maximum potential.
·
Higher reliability1. Adopt a special valve that is frequently switched over 1 million times without failure to ensure the system's
Stable operation.
2. The system design is more reasonable, and the equipment is safer and more reliable.
More convenient to use1. Nitrogen can be automatically recorded, which is convenient to find the working status at any working time.
2. The system runs fully automatically, and the whole process can be unattended.
