Description

How it works:
Under some pressure due to dynamic effects, oxygen diffusion rate of nitrogen in carbon molecular sieve differences, within a short time, the oxygen molecules of carbon molecular sieve a large number of adsorption of nitrogen molecules in the gas phase enrichment to achieve the separation of oxygen and nitrogen.
Significant difference due to the adsorption capacity of the carbon molecular sieve oxygen with different pressure, reduce stress, to desorption of oxygen molecules adsorbed by carbon molecular sieves, carbon molecular sieve regeneration, able to repeat the cycle. Two adsorption tower in a tower adsorption capacity of nitrogen, another tower desorption regeneration cycles of the continuous output of high quality nitrogen.
Features:
Low energy consumption, equipment operation, cost, adaptability, and gas production is fast, easy to adjust purity;
Improve the process design, optimal results;
Modular structure designed to save floor space;
Easy operation, stable performance, high degree of automation can realize unmanned operation;
The internal structure of design, to improve the efficiency of the carbon molecular sieve adsorption;
Special air diffusion device, reduce the airflow speed impact, and to extend the life of the carbon molecular sieve;
Automatic interlock shorting device to ensure the quality of the finished product nitrogen;
Multiple fault diagnosis, alarm and automatic processing capabilities;
Optional touch screen display, dew point detection, energy-saving control, DCS communications
