Coal Mine Nitrogen Generator

Nitrogen has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable.

Specifications:

1) Capacity: 1 - 5000Nm3 / hr

2) Purity: 90 - 99.9995%

3) Outlet Pressure: 0.05 - 1.0 Mpa

4) Dew point: - 50 oC

 

Principles:

PSA nitrogen generator uses carbon molecular sieve as sorbent, produces nitrogen by making use of the PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity.PLC controls pneumatic valve on/off to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity.
