由于氮分子筛对氧的吸附容量随压力的不同而有明显差异，降低压力，即可解吸碳分子筛吸附的氧分子，使碳分子筛再生，得以重复循环使用。
采用两个吸附塔工艺，一塔吸附产氮，一塔解吸再生，循环交替，连续产出高品质氮气。
QBN PSA Nitrogen Generator
The Working Principle
PSA nitrogen generating equipment use the high quality carbon molecular sieve as adsorbent, and utilize PSA principle , acquiring nitrogen gas from compressed air directly.
Under the certain pressure , the spread rate of oxygen and nitrogen on carbon molecular sieve has big differences . Because of the oxygen molecules is adsorbed by carbon molecular sieve , nitrogen molecules enriches at gaseous phase , so nitrogen and oxygen get separated .
Choose two adsorption tower processes ,one tower adsorption produce nitrogen , the other desorption regenerate , the two circulation alternate , continuously output high quality of nitrogen.
