    PSA Nitrogent ( N2) Generator/ Plant for Coal Mine

    Quantity Order:
    Origin:
    China
    Payment Method:
    Telegraphic Transfer (T/T), L/C

    Specification :

    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.
