Device
Configuration
1.
Air Compression System: Air be compressed to 0.5-0.7 Mpa by air
compressor, Imported centrifugal air compressor, high efficiency,
low consumption, stable and reliable operation.
2. Pre-cooling System: The air is pre-cooled to 5-10ºC in the
pre-cooling unit, and the moisture is separated. The original
imported screw refrigeration compressor and the air-conditioning
unit combined with all imported refrigeration components are
equipped with a water separator, manual and imported automatic
drains to drain water regularly.
3. Air Purification System: Removing the remained moisture,
carbon dioxide and hydrocarbons of compressed air in the
molecular sieve purifier. The purifier adopts a vertical
single-layer bed with simple and reliable structure and low
resistance loss; built-in filter, blowing off and purifier
regeneration at the same time; high-efficiency electric heater
ensures complete regeneration of molecular
sieve.
4. Fractionating Column System (Cold Box): accumulation and
purification of the fractionating tower can be completed in one
way, and the operation is simple, quick and easy. Adopt aluminum
plate-fin heat exchanger, aluminum convection sieve plate tower,
the entire fractionating tower equipment pipeline adopts argon
arc welding, the tower body and main pipeline in the cold box are
made of high-strength aluminum alloy or stainless steel to
increase the strength , Reduce the torsion damage of the
pipeline. The equipment brackets, pipes and valve brackets in the
cold box shall be made of stainless steel or aluminum alloy. The
cold box is insulated with pearl sand and slag wool to ensure
that the loss of cold capacity is minimized. The cold box
structure guarantees the overall strength and the requirements of
anti-seismic and wind resistance, and guarantees the load-bearing
capacity of the cold box. When the cold box is running, it is
equipped with airtight protection and safety devices. The main
equipment in the cold box is equipped with electrostatic
grounding. The cold valve and pipeline in the cold box all
connections are welded, and flange connections are
avoided.
5. Turbo Expander System: The air expands and cools in the turbo
expander and provides the cooling capacity required by the
device.The turbo expander adopts gas bearing, which is simple and
reliable, easy to operate, and high efficiency. The cold box of
the expander is set separately for easy
maintenance.
6. Heat Exchange System: The air exchanges heat with the
refluxing oxygen, nitrogen, and dirty nitrogen in the heat
exchanger of the fractionation tower, and is cooled close to the
liquefaction temperature, and the refluxed oxygen, nitrogen, and
dirty nitrogen are repeatedly heat exchanged to the ambient
temperature.
7. Filling System: Single gas production: Internal compression
process ( Cryogenic liquid pump, High pressure vaporizer, Filling
manifold).
Multi-gas production: External compression process (Oxygen &
nitrogen & argon booster, Filling manifold).
8. Instrument and Electric Control System: Siemens imported
brand, Fully automatic production system, Digital control
system.
9. Others: Equipment layout drawing (according to civil
engineering design), Process pipe design drawings, Instrument
electrical design drawings, etc.

PSA OXYGEN GENERATOR
Following the principle of pressure swing adsorption zeolite
molecular sieve is used as the adsorbent. A full set PSA oxygen
plant consists of 5 parts. Fresh air as raw material, passing
through air compressor abtain 5-10 Bar compressed air. After
compressed air purification system the waste gas, water, oil,
dust will be filted and exhausted You can connect with hospital
tube or another pipes to use directly, but also you can fill into
cylinders.if so, we can supply oxygen booster and filling
manifold
CRYOGENIC LIQUID STORAGE TANK
Designing of cryogenic liquid storage tank is done in way to
ensure that it is sturdy, compact and easy to operate. Top end
liquid filling decreases the pressure inside the tank and the
bottom filling increases the pressure. The pressurizing system is
used for increasing the pressure when the liquid oxygen is
uploaded to tanks or gas line vaporizers. As the pressurizing
system is used for regulating the opening of both top and bottom
filling valve, there is almost no change of pressure during
liquid delivery. It enables constant liquid supply to vaporizer.
GAS COMPRESSOR
The equipment does not need to add lubricating oil, and the
exhaust gas does not contain oil and oil vapor, so it can be
protected from pollution, eliminating the need for complex
filtration and purification systems, saving equipment costs and
maintenance costs, and has significant features such as safety,
reliability, and easy operation.
