Working principle of PSA nitrogen generatorPressure Swing
Adsorption (PSA) is a new type of gas adsorption and separation
technology. It has the following advantages:The product has high
purity.It can work at room temperature and common pressure
(0.8mpa), without heating during bed regeneration, which is
energy-saving and economical. The equipment is easy to operate
and maintain.Continuous cycle work, which can be fully automated.
PSA is a new type of gas adsorption and separation technology,
which has the following advantages: High product purity. It can
work at room temperature and common pressure (0.8mpa), without
heating during bed regeneration, which is energy-saving and
economical. The equipment is easy to operate and maintain.
Continuous cycle work can be fully automated. With 5A zeolite
molecular sieve adsorbent, a two-bed PSA device is used to separate
oxygen enrichment from the air and separate O2 and N2 in the air to
obtain nitrogen. Carbon molecular sieve is a kind of ink-colored
particles which are specially processed from coal powder. Its
surface is covered with numerous micropores. The principle of air
separation depends on the different diffusion speeds of oxygen and
nitrogen in the pores of carbon molecular sieve. The diffusion
speed of oxygen into the pores of molecular sieve is much faster
than the diffusion speed of nitrogen, so that oxygen molecules are
adsorbed in the pores of carbon molecular sieve. , And nitrogen
molecules are enriched in the gas phase. At the same time, the
capacity of carbon molecular sieve to adsorb oxygen increases due
to its pressure increase, and decreases due to its pressure drop.
In this way, the carbon molecular sieve adsorbs when pressurized,
and desorbs the oxygen component under reduced pressure, forming a
cycle operation to achieve the purpose of separating air. Referred
to as PSA Nitrogen. Equipment installation diagramΔ Advanced
inequality pressure equalization process improves the utilization
of carbon molecular sieve and directly reduces compressed air
consumptionΔ Advanced internal structure, air flow deceleration,
uniform distribution, reduce the impact force on the molecular
sieve, and improve the service life of the molecular sieveΔ We
cooperate with well-known molecular sieve manufacturers at home and
abroad, and can choose the most energy-saving and efficient ratio
according to actual working conditions.Δ Reliable air source
treatment accessories ensure the stable operation and service life
of the equipment.Δ Adopting the blizzard filling method, the
molecular sieve is filled more evenly and densely, the friction
coefficient is reduced to the minimum, and the whole machine is
improved Reliability of long-term operation.Δ It adopts
Siemens PLC programmable controller for automatic control, one-key
start without special personnel operation, and can be reserved for
computer, mobile phone, etc.Remote device connection, real-time
observation of operation.Δ The valve is the key to the stable
operation of the equipment, with fast opening and closing speed,
low energy consumption, simple structure, good sealing performance,
installation and maintenance Convenient and long service
life.Δ Using a special spring compression device, when the
molecular sieve in the adsorption tower decreases, it will
automatically compensate to eliminate the problem of molecular
sieve powdering. Extended service life.Δ Automatic
emptying of unqualified nitrogen/manual emptying
(optional)Δ The original components of famous brands at home
and abroad are selected to ensure the operation of the equipment
and the quality of nitrogen.ΔPSA N2 generator (Purity 99.5%
