The principle of PSA Nitrogen Generator and PSA Oxygen Generator
PSA Nitrogen Generator making device is according to the pressure swing adsorption (PSA) technology, using high quality carbon molecular sieve as adsorbent separation oxygen nitrogen directly from the compressed air. After dry compressed air purification, under the effect of pressure, the use of oxygen diffusion in PSA Nitrogen Generator carbon molecular sieve pores adsorption rate greater than the diffusion of nitrogen in carbon molecular sieve pores adsorption rate, this feature in ad
sorption equilibrium has not been achieved, the enrichment of nitrogen in the gas phase was up and form a finished product nitrogen. Then via vacuum to atmospheric pressure, adsorbent adsorption by stripping of impurities such as oxygen, realize regeneration. In the system is set in the two adsorption tower, a tower adsorption nitrogen production, another stripping tower regeneration, controlled by PLC program controller of pneumatic valve opening and closing, make the two tower cycle of work, realize the continuous production of high quality nitrogen.
PSA Nitrogen Generator Features:
- Specific pressure protection measures of molecular sieve, molecular sieve is difficult of pulverization, long service life.
- Low energy consumption, the product of high oxygen purity.
- Reasonable internal components, air distribution uniformity, reduce air high-speed impact.
- The PSA Nitrogen Generator of a high degree of automation.
- Multifunctional monitoring system, realize gas, purity, pressure LCD online display, equipment failure warning, maintenance tips, fully grasp equipment running states.
- Can be fully integrated skid mounted design, easy installation and rapid debugging.
- Optional oxygen flow, remote monitoring system, etc.
Pressure swing adsorption principle:
PSA technology (Pressure Swing Adsorption, referred to as the PSA technology): is an advanced gas separation technology to the adsorbent (porous solid matter) on the inner surface of the physical adsorption of gas molecules based on the use of adsorbent at the same pressure and easy absorption high-boiling gas, easy to absorb low-boiling gases, and high pressure is increased adsorption of gas absorption, adsorption of low pressure is absorbed by the gas reduction features to achieve the separation of gases. Such impurity adsorption under pressure and desorption under reduced pressure impurities to regenerate the adsorbent in the process is pressure swing adsorption cycle.
PSA is a new gas separation technology, PSA Oxygen Generator principle is to use molecular sieves for differences gas molecules "absorption" properties and the gas mixture is separated, which is based on the air as raw material, using a high-performance, high selected solid adsorbents the performance of selective adsorption of nitrogen and oxygen, the oxygen and nitrogen in the air is separated.
Overall PSA Oxygen Generator can be divided into:
- compressed air system (air compressor, air dryer, air tank and filter)
- PSA
- oxygen tank
- oxygen cylinders and oxygen booster
