Principle of Operation
Under the balance of adsorption, when any kind of adsorbent adsorbs
the same gas, the higher the gas pressure, the greater the
adsorption capacity is. Otherwise, the lower the pressure, the
smaller the adsorption power
carbon molecular sieve shows difference in adsorbing oxygen and
nitrogen. Carbon molecular sieve is a substance with a lot of
micropores inside. The PSA principal is to achieve the separation
goal of oxygen and nitrogen which based on the adsorption quantity
difference in the carbon molecular sieve when the pressure is
certain.
When the pressure rises, the carbon molecular sieve adsorbs the
oxygen and produces the nitrogen gas. When the pressure decreases,
the carbon molecular sieve starts to desorb the oxygen until the
pressure equals to the ordinary pressure. At that time, the carbon
molecular sieve desorbs the oxygen completely. The PSA nitrogen
generator is usually equipped with adsorption towers. It controls
the pneumatic valve by PLC, thus the two adsorption towers can
produce the nitrogen gas alternatively. One tower adsorbs the
oxygen and produces nitrogen gas, the other desorbs to regeneration
to produces the required nitrogen.
Process Flow Brief Description
Composition of PSA nitrogen making machine
Compressed air purification system:Carbon molecular sieve is the
key material to determine the production capacity of nitrogen
machine. Since the compressed air provided by air compressor
usually contains oil and water, oil and water will reduce the
adsorption capacity of carbon molecular sieve, so the compressed
air needs to remove oil and water before entering the oxygen and
nitrogen separation system. Firstly, the air is compressed by the
compressor to be 0.75-1.0 MPa and enter air purification system,
the pipeline filter will remove most of the water, oil and
mechanical impurities, and then the freeze drying machine dewaters
by cooling and make the pressure dew point to be 2 ℃ to 10 ℃,
furthermore, the air is processed by the precision filter, super
precision filter and activated carbon degreaser, the air with
pressure 0.75-1.0 MPa, pressure dew point with 2 ℃ to 10 ℃, and the
oil content less clean 0.01 PPm will be got. Compressed air
purification system is composed of pipeline filter, freeze-drying
machine, fine filter, ultra-fine filter, activated carbon deoiler,
automatic sewage valve, ball valve and so on.
