Runoff: 200-1200Nm3/ h
Purity 99-99.9%
Pressure 0.05-0.65Mpa
Dewpoint -20- -45
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.
Applications:
Inject nitrogen into the oxidation space of mining empty zone or fire zone to reduce the proportion of oxygen to less than 10% or 3% , to achieve fireproofing and blast-proof, such as:
1. Eliminate danger of fire damp explosion.
2. Reduce air leak effect.
3. Reduce temperature
4. Prevent the coal from heating and self-ignite.Reduce burning intensity.
