PSA nitrogen making facility used in rubber tires industry
PSA Nitrogen Generator
1, Working principle of PSA nitrogen Generator:
Pressure swing adsorption nitrogen production device is a new type
of air separation equipment, with compressed air as the raw
material and carbon molecular sieve as the adsorbent.Using PSA
process under the normal temperature and low pressure, the pressure
swing adsorption (PSA) oxygen and nitrogen in carbon molecular
sieve using the air diffusion rate is different, through the
programmable controller control valve opening and closing, realize
the pressure adsorption and vacuum stripping process, complete
separation oxygen, nitrogen, get high purity nitrogen, nitrogen
purity and gas production rate can be adjusted according to the
customers' needs.
Our company produces the ordinary nitrogen type nitrogen making
device, nitrogen purity is 98 ~ 99.99%, nitrogen production volume
is 5 ~ 1000 Nm3 / h, the ordinary nitrogen type nitrogen making
device with nitrogen gas purification device becomes a high purity
nitrogen type of nitrogen making system, nitrogen purity can reach
to 99.9995%, the oxygen levels in the nitrogen is less than or
equal to 5 PPM, dew point less than or equal to - 60 ℃.

- Low cost: the advanced PSA process is a simple nitrogen production
method. Nitrogen is generated within a few minutes after starting
up, with low energy consumption. The cost of nitrogen is lower than
that of cryogenic air separation nitrogen production.
- Reliable performance: imported microcomputer control, automatic
operation, no special training operators, just press the start
switch, can automatically operate, to achieve continuous production
of nitrogen.Nitrogen purity is stable and is monitored and
displayed by the instrument to ensure the required nitrogen purity.
- Excellent imported carbon molecular sieve: it has the
characteristics of large adsorption capacity, high compression
resistance and long service life.
- High quality control valve: excellent imported special pneumatic
valve can ensure the stable and reliable operation of nitrogen
production equipment.Strong technical force and excellent
after-sales service.Equipment is containerized, and only gas
source, power source and water source need to be connected during
field installation.Excellent electrical and mechanical assembly
technology, provide continuous technical service, be responsible
for site commissioning and training operation.
- Fast start-up speed, 15-30 minutes to provide qualified nitrogen.
- Fully automatic operation of the equipment, the whole process can
be realized unattended.
- High efficiency molecular sieve filling, more compact, more solid,
longer service life.
- Stable and adjustable pressure, purity and flow to meet different
needs of customers.
- Reasonable structure, advanced process, safe and stable, low energy
consumption, compared with bottled nitrogen, liquid nitrogen
operation of high cost, nitrogen production mechanism to take the
lowest cost of nitrogen, for long-term engaged in food, chemical
products, hardware products, pharmaceutical products and other
production and processing enterprises, the use of nitrogen machine
is the most cost-effective.
Main Application Fields: PSA Nitrogen Generator widely used in
Electronic industry, metallurgy industry, petrochemical industry,
food industry, pharmaceutical industry, chemical fiber industry,
heat treatment industry, rubber tires etc.
3,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.
- Air tank system: The purpose of the air storage tank system is to
ensure the stability of the gas used in the oxygen and nitrogen
separation system. When the oxygen and nitrogen separation system
is switched, it can prevent the instantaneous airflow velocity from
going too fast, affect the air purification effect, improve the
quality of compressed air entering the adsorber, and help to extend
the life of the molecular sieve.Air tank system consists of air
tank, protective valve, globe valve, ball valve, pressure gauge,
etc.
- Body of Nitrogen making machine:Oxygen and nitrogen separation
system is the core part of air separation. Its main body is two
adsorption towers filled with carbon molecular sieve. When the
clean compressed air enters the adsorption tower, oxygen, carbon
dioxide and trace water are absorbed by the carbon molecular sieve,
and nitrogen is output from the outlet end. When nitrogen is
adsorbed in one column, oxygen, carbon dioxide and water adsorbed
in the molecular sieve can be discharged from the pores by
decompression in the other column to achieve biodesorption of the
molecular sieve.The two columns adsorb and regenerate alternately
and continuously output nitrogen.The main body of nitrogen making
machine is composed of adsorption tower, carbon molecular sieve
filled in the tower, pneumatic valve, muffler, throttle valve,
compression cylinder, pressure gauge and so on.
- Nitrogen buffer system : The main function of nitrogen buffer
system is to balance the pressure and purity of nitrogen separated
from the main body of nitrogen making machine and ensure the
continuous supply of nitrogen.At the same time, when the adsorption
tower is transformed from regeneration to adsorption, it will
recharge the partially qualified nitrogen stored in the adsorption
tower to protect the molecular sieve bed, and also help the
adsorption tower boost pressure.At the same time, when the
adsorption tower is regenerative to adsorption, it will recharge
the partially qualified nitrogen stored in the protective bed of
the adsorption tower, and also help the adsorption tower boosting
pressure. Nitrogen buffer system consists of buffer tank, flow
meter, dust filter, pressure regulating valve, throttle valve,
protective valve, etc.
- Electrical Control System :The main functions of the electrical
control system are equipment start and stop operation, working
status indicator light display, fault sound-light alarm indication,
purity display and drive pneumatic valve according to the set
program.The electrical control system is composed of programmable
controller, air source triplex, solenoid valve, indicator light,
micro oxygen meter, etc. It is mainly installed in the electric
control cabinet.
