10nm3 20nm3 50nm3 80nm3 PSA VPSA Cryogenic Nitrogen Oxygen
Generator
Product description
VPSA (Vacuum Pressure Swing Adsorption)
It separates nitrogen and moisture from the air, efficiently
producing oxygen with a purity of 80% to 95%. VPSA oxygen
production equipment plays a significant role in traditional
industries such as steel, glass fiber and special materials, paper
making, wastewater treatment, cement, ceramics, and glass furnaces,
as well as in non-ferrous smelting, solid waste recycling, and
other fields.
GNEE VPSA oxygen production equipment is an energy-saving and
environmentally friendly product.
Compared to traditional technologies, the blower and vacuum pump
can save energy by 8-12%, with low noise and intelligent control,
reducing the overall cost of equipment oxygen production.

Working Principle
The VPSA Oxygen Generator is an air separation unit which is based
on molecular sieves selective adsorption of nitrogen from air and
can continuously generate gas oxygen with a purity 90~ 94% at
ambient temperature, and the adsorbed nitrogen can be desorpted by
decreasing the adsorbed bed pressure resulting cyclical
adsorption-desorption operation.
The filtered air is conveyed by the blower and enters the
adsorption tower A or B which is equipped with molecular sieves and
activated alumina. When the air flows through the fixed bed layer
of molecular sieves inside the tower, the nitrogen molecules in the
air diffuse into the solid of the molecular sieve under the
adsorption force. The oxygen molecules and nitrogen atoms then pass
through the bed layer to the buffer tank and are pressurized by the
oxygen compressor to the user's usage pressure, and then sent to
the storage tank for user's use.
After a period of adsorption, the molecular sieve particles are
filled with nitrogen molecules, reaching the saturation stage of
adsorption. At this point, the air inlet valve is closed, and the
oxygen-rich air in the tower is used to flush the other tower that
has just been evacuated of air. When the pressure drops to a
certain value, the equal pressure valve is closed, and at the same
time, the vacuum pump inlet valve is opened to evacuate the vacuum
from the tower.
After reaching a certain vacuum level, the oxygen-rich gas from
another tower and a portion of the product gas from the middle
section of the buffer tank are used to flush the molecular sieve,
thereby completely desorbing the adsorbent. After the desorption
process of the adsorbent is completed, the tower is pressurized
with the product gas. When the pressure reaches a certain low
vacuum level, the buffer valve is closed, and the outlet valve of
the blower is opened to pressurize the adsorption tower, preparing
for the next adsorption process.
