How the equipment works


The raw air will be removed its particle by inlet filter and then be pressurized to about 40Kpa. 


The air temperature from the air blower is about 75℃, after to be cooled by cooling water, it will flows into one of adsorption tower which filled with adsorber.When the raw air flows from the bottom tower to upper tower, the nitrogen will be adsorbed, oxygen will be oncentrated at the top of tower and be delivered out as product gas.


When the adsorber almost reaches to saturation, in the action of controller, the valves will be switched, the raw air flows into another adsorption tower to adsorb. Saturated adsorption tower will be decompressurized to atmosphere pressure and then be vacuumized to about -60Kpa,product gas will be introduced into the tower to pruge the adsorption bed , thereby, the adsorber will be desorbed, and  prepare for the next cycle.


The two adsorption towers adsorb and desorb alternately to produce oxygen gas continuously.


Raw air shifting from one adsorption tower to another tower is controlled by pneumatic valves, the action process of valves is realized by PLC controller. Centralized control system enables the whole system to work automatically.

Uses of PSA Oxygen Generator

Oxygen is a tasteless gas. It has no smell or color. It comprises 22% of the air. The gas is part of the air people use to breathe. This element is found in the human body, the Sun, oceans and the atmosphere. Without oxygen, humans will not be able to survive. It is also part of the stellar life cycle.


Common Uses of PSA Oxygen Generator

This gas is used in various industrial chemical applications. It is used to make acids, sulfuric acid, nitric acid and other compounds. Its most reactive variant is ozone O3. It is applied in assorted chemical reactions. The goal is to boost reaction rate and oxidation of unwanted compounds. Hot oxygen air is required to make steel and iron in blast furnaces. Some mining companies use it to destroy rocks.


PSA Oxygen Generator Usage in the Industry

Industries use the gas for cutting, welding and melting metals. The gas is capable of generating temperatures of 3000 C and 2800 C. This is required for oxy-hydrogen and oxy-acetylene blow torches. A typical welding process goes like this: metal parts are brought together.


A high temperature flame is used to melt them by heating the junction. The ends are melted and solidify. To slice metal, one end is heated until it turns red. The oxygen level is augmented until the red hot component has oxidized. This softens the metal so it can be hammered apart.


Atmospheric Oxygen - PSA Oxygen Generator

This gas is required to produce energy in industrial processes, generators and ships. It is also used in airplanes and cars. As liquid oxygen, it burns spacecraft fuel. This produces the thrust needed in space. Astronauts’ spacesuits have close to pure oxygen.


PSA Oxygen Generator Use in Medicine and Health

In healthcare institutions like hospitals, oxygen supplies are kept in stock. These are provided to patients who have difficulty breathing. This breathing apparatus is also used by astronauts walking in space, scuba divers and mountaineers. Oxygen gas is used to destroy bacteria. The same oxygen gas is used to treat victims of carbon monoxide poisoning.


PSA Oxygen Generator usage in Respiration

Of all the uses of oxygen, sustaining life is the most important. Oxygen is needed by all living organisms. Through a process known as aerobic respiration, energy from food is generated. This allows humans and animals to perform their daily activities.


Other PSA Oxygen Generator Applications

This gas is used in water treatment and chemical combustion. Scientific researchers use the oxygen-18 and oxygen-16 isotopes in fossils to determine Earth’s climate millennia ago. This gas is also used in polyester polymers and antifreeze production. These polymers are used to create fabrics and plastics. You will also find oxygen tanks in aircraft and submerge vessels.


Chemical Properties - PSA Oxygen Generator

Oxygen comprises a fifth of air volume, two-thirds of the human body and 87% water. In its natural form it is all over the atmosphere. Commercial preparation involves fractional distillation of air and liquefaction and water electrolysis. Of the group 16 of the periodic table, it is the primary member. Oxygen can be used to make compounds with all elements minus inert gasses.


Oxygen may be dissolved. This gas supports combustion. However, it does not conduct electricity or heat well. Oxygen in the air is known as diatomic gas. Ozone O 3 is an allotrope. It is composed of ultraviolet light or electrical discharge.


Oxygen is paramagnetic whether it is gaseous, liquid or solid. Oxides are generated when oxygen joins with other elements. It is part of hydroxides and various acids. Oxygen can be cooled under boiling point. It will turn light blue. This color is retained even when in a solid state.


Oxygen Toxicity

This condition takes place when someone breathes excessive pure oxygen. The gas is essential for living, but only up to a point. Humans can only breathe 21 percent oxygen. The other elements are composed of nitrogen and other elements. When too much oxygen is inhaled, humans will experience difficulty breathing. Other symptoms will manifest. These include inflammation of the airways, nausea and tunnel vision.


Toxicity can be due to elevated oxygen levels or other causes. High pressure, short duration exposure can lead to central nervous system damage. Long term exposure may cause ocular or pulmonary problems. Central nervous system oxygen toxicity is usually experienced by divers. Those who spend time at high altitudes are also susceptible. Toxicity can occur when a diver goes in deep enough. This is because the diver takes in more oxygen than usual.


Symptoms include twitching, dizziness and nausea. In extreme cases, seizures or death occur. However, toxicity can take place in normal atmospheric pressure. This can occur when air oxygen is higher than 21%. At 50%, toxicity will occur.


The uses of oxygen are varied. Aside from those mentioned here, it is used in pulp and paper manufacturing, ceramic creation, glass making and petroleum processing. It is also part of pharmaceuticals, metal refining and other elements.


Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O2. This is an important part of the atmosphere and diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. Additionally, as oxides the element makes up almost half of the Earth's crust.


Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. Conversely, oxygen is continuously replenished by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O3), strongly absorbs ultraviolet UVB radiation and the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation. But ozone is a pollutant near the surface where it is a by-product of smog. At low earth orbit altitudes, sufficient atomic oxygen is present to cause corrosion of spacecraft.


Oxygen was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first. The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion.


Common use of oxygen includes residential heating, internal combustion engines, production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
