Industrial Large-Scale Nitrogen Generator Nitrogen Generator
Equipment
Working principle: According to the principle of variable pressure
adsorption, high quality carbon molecular sieve is used as
adsorbent to produce nitrogen from air under a certain pressure.
After purified and dried compressed air, it is adsorbed under
pressure and desorbed under reduced pressure in the adsorber. Due
to the aerodynamic effect, the diffusion rate of oxygen in the
micro-pores of the carbon molecular sieve is much larger than that
of nitrogen, and oxygen is preferentially adsorbed by the carbon
molecular sieve, while nitrogen is enriched in the gas phase to
form the finished nitrogen gas. Then by reducing the pressure to
atmospheric pressure, the adsorbent desorbs the adsorbed oxygen and
other impurities, is to achieve regeneration. Generally, two
adsorption towers are set up in the system, one tower adsorption
nitrogen production, the other tower desorption regeneration,
through the PLC program controller to control the start and close
the pneumatic valve, so that the two towers alternate cycle, in
order to achieve the purpose of continuous production of nitrogen.
