The PSA Process : A High Technology Perfectly Known Medical

The PSA Process : A High Technology Perfectly Known Medical The oxygen generator is based on a patented implementation of the Pressure Swing Adsorption (PSA) which uses ambient air as raw material. Ambient air contains 21% oxygen, 78% nitrogen, 0.9% argon and 0.1% rare gases. The PSA process is a static separation of air gases via a specific molecular sieve designed to adsorb nitrogen under pressure, to produce oxygen-enriched air composed of 93% oxygen and above. The oxygen generator is mainly composed by 2 separation vessels filled with molecular sieve adsorbers (zeolites), one complete pneumatic system (valves, filters, pressure regulator...) monitored by an automatic device, and an oxygen tank.

WHAT IS PSA ?

Pressure swing adsorption Pressure swing adsorption (PSA) is a technique used to separate some gas species from a mixture of gases (typically air) under pressure according to the species' molecular characteristics and affinity for an adsorbent material. It operates at near-ambient temperature and significantly differs from the cryogenic distillation commonly used to separate gases. Selective adsorbent materials (e.g., zeolites, (aka molecular sieves), activated carbon, etc.) are used as trapping material, preferentially adsorbing the target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed gas. Process Pressure swing adsorption process (PSA) is based on the phenomenon that under high pressure, gases tend to be trapped onto solid surfaces, i.e., to be "adsorbed". The higher the pressure, the more gas is adsorbed. When the pressure is dropped, the gas is released, or desorbed. PSA can be used to separate gases in a mixture because different gases are adsorbed onto a given solid surface more or less strongly. If a gas mixture such as air is passed under pressure through a vessel containing an adsorbent bed of

The Different of Medical Oxygen Generators and Household Oxygen Generators

The functions of medical oxygen generators and household oxygen generators are as follows: The first is used for medical purposes. Some respiratory diseases or chronic obstructive pneumonia may require oxygen. Of course, other patients with severe hypoxia, such as gas poisoning, also need medical oxygen generators. The second is health care functions, such as middle-aged and elderly people, pregnant women and college students with high pressure. Short-term hypoxic responses may be present after severe physical exertion or severe cerebral energy expenditure. The use of a medical oxygen concentrator can prevent the sequelae caused by short-term hypoxia. The third category is the main equipment of some small and medium-sized hospitals. For example, some remote mountainous areas and plateaus, these areas are relatively hypoxic. If the medical hypoxia machine is not prepared, it may cause unnecessary damage when it needs to be used. A common type is a pressure swing adsorption oxygen generator, which extracts oxygen from the air. The medical oxygen generator is filled with molecular sieve, and the surface area of each gram of molecular sieve can reach 800-1000m 2/g. In the case of decompression of the molecular sieve, the previously adsorbed nitrogen gas is discharged into the air again. When repressurized, nitrogen can be adsorbed for the production of oxygen. Therefore, the medical oxygen generator can realize periodic cyclic oxygen generation, which is a dynamic process.

PSA Pressure Swing Adsorption Nitrogen Generator Installation Requirements

PSA Pressure Swing Adsorption Nitrogen Generator Installation Requirements 1. A large enough site should be selected according to the actual size of the nitrogen generator. The distance between the machine and the surrounding environment should be kept more than 1 meter for the convenience of operation. 2. The installation site must have good ventilation and less dust. 3. Cannot be installed in a corrosive environment. 4. The muffler (the exhaust gas outlet of the PSA nitrogen generator) can be installed indoors or outdoors. When the air compressor and the nitrogen generator are in the same room, the muffler should be installed outdoors to avoid affecting the nitrogen production. 5. The nitrogen generator should be placed in a place with poor ventilation, and the muffler should be installed outdoors. 6. If the muffler is installed outdoors, the muffler installed outdoors should be equipped with rainproof facilities. Pay attention to the height of the muffler not higher than the exhaust gas outlet. Otherwise, the sewage from the pipeline will not only be unable to be discharged, but it will easily cause the sewage to be poured back. 7. Notes on power supply installation: The power supply should be configured according to the calibrated voltage (V), current (A) and number of phases. The grid voltage should be within the range of AC ±10%. The installation of the nitrogen generator must be carried o

Main Technical Characteristics and Performance Description of Explosion-proof Nitrogen Generator

Main technical features of explosion-proof nitrogen generator: The explosion-proof industrial nitrogen generator uses air as the raw material, carbon molecular sieve as the adsorbent, using the principle of pressure swing adsorption, and the method of separating nitrogen and oxygen by the selective adsorption of oxygen and nitrogen by carbon molecular sieve, commonly known as PSA nitrogen production. The structure design of the adsorber used in the nitrogen generator has its own unique features. The upper and lower parts of the adsorber have reliable filtering devices, and a special pressing device is designed, so that the adsorber does not need to add molecular sieves during use. Due to the unique structural design of the adsorber, the distribution of the air flow is quite uniform, thus ensuring the excellent performance of the machine to a large extent. Main technical performance of explosion-proof industrial nitrogen generator: 1. The whole machine is explosion-proof: explosion-proof industrial nitrogen generator, the whole machine can be manufactured not only as underground mobile type, but also as ground fixed type or ground mobile type. 2. Small size, easy installation and movement: The explosion-proof industrial nitrogen generator can be easily moved to any nitrogen injection site, especially suitable for random use in multiple working faces or mines. 3.

Why does the Oxygen Concentration Drop in the PSA Oxygen Generator?

As an industrial equipment, the PSA oxygen production system can avoid mechanical wear and tear during the perennial operation, which will lead to the decline of product performance. Among them, the decline of oxygen concentration is a more important problem, especially in the field of medical PSA oxygen production. Therefore, this article has sorted out several common factors that lead to low oxygen concentration, which are summarized as follows: 1. The intake air volume of the PSA oxygen generation system is too large or too small. Using the PSA pressure swing adsorption method to produce oxygen, the adsorption capacity of the core component molecular sieve is relatively fixed. Too large or too small intake air may prevent the molecular sieve from producing sufficient oxygen, so the oxygen concentration will be low. The key is to strictly carry out product selection and system planning, and select appropriate pipelines and regulating appropriate valves to control the intake air volume. 2. The compressed air pressure is unstable. When the compressed air enters the molecular sieve, the pressure cannot be within the specified range. The sudden high and low air pressure will affect the working efficiency of the molecular sieve and cause insufficient oxygen production. The more common treatment method is to add an air storage tank before the air enters the molecular sieve. . 3. Molecular sieve quality. Although molecular sieves can work continuously for 8-10 years under normal use conditions, molecular sieves will suffer natural loss during use. When the loss reaches a certain level, sufficient oxygen will not be produced, resulting in a decrease in oxygen concentration. Therefore, it is necessary to check the molecular sieve regularly to ensure the normal and efficient operation of the molecular sieve. 4. Filter element. The filter of the PSA oxygen production system is mainly to filter out impurities, moisture and oil in the air to make th

PSA oxygen system precautions

Precautions when filling oxygen cylinders 1. The operator's hands, labor protection supplies and tools should avoid oil. When there is grease, it is forbidden to contact with oxygen cylinders and oxygenation valves. 2. The valve should be opened and closed slowly, and it should be fully opened or closed at a time to avoid generating excitation energy. 3. When the empty bottle is placed on the platform to equalize the pressure, if there is a strong airflow sound, it should be stopped immediately, and the gas bottle should be removed for inspection. 4. Check the temperature of the gas cylinder during the filling process. When the temperature is found to be abnormal, stop the inflation and remove it for inspection. 5. The gas cylinder must be protected by an anti-fall chain. 6. When filling the bottle, if air leakage is found, the power supply should be cut off first, and no maintenance under pressure is allowed. 7. When the inflation pressure is greater than 10MPa, it is strictly forbidden to refill the empty bottle halfway, and all personnel are not allowed to enter the filling room. 8. Gas cylinders must be filled with anti-misfit joints to prevent other gas cylinders from being filled with oxygen. 9. When the gas cylinder is transported, a safety helmet and shockproof ring should be installed, and it is strictly forbidden to throw, throw, roll or touch. 10. The filling site should have obvious fire signs, and no fireworks are allowed. 11. The filled gas cylinders should be affixed with warning labels and filling labels that comply with national standards. 12. If the gas cylinder catches fire during filling, the main gas source should be cut off immediately, the filling branch valve should be closed, and corresponding fire fighting measures should be taken.

What are the Factors that Affect the Performance of Oxygen Generators by the Environment?

The same oxygen generator will have different performance in different environments, because a suitable environment can exert the performance of the oxygen generator, and an unsuitable environment will reduce the performance of the oxygen generator and increase the cost of production and consumption. Specifically, the environment in which the oxygen generator is located has four factors that need to be carefully considered, including atmospheric pressure in the air, ambient temperature, atmospheric humidity and carbon dioxide. 1. The influence of atmospheric pressure will increase the compression ratio of the air compressor. If the atmospheric pressure decreases by 001MPa, the compression ratio of the air compressor will increase by 6%~8%, and the compression energy consumption will increase. In addition, the reduction of atmospheric pressure will reduce the displacement of the air compressor, the corresponding oxygen production will also decrease, and the power consumption of the oxygen generator will also increase. 2. When the ambient temperature increases, the displacement of the air compressor will also decrease, which means that the shaft power will increase. The data shows that for every 3°C increase in ambient temperature, the shaft power increases by about 1%. At the same time, the increase of the ambient temperature will also lead to the increase of the exhaust temperature of the air compressor, which requires more cooling capacity to balance the cooling loss, and ultimately leads to an increase in energy consumption. 3. The influence of air humidity means that the humidity in the air is high, and the air compressor will consume more power when dealing with water vapor, thereby increasing the energy consumption of the air compressor. 4. The influen

Factors Affecting Oxygen Concentrator Stability

Nitrogen generator is a nitrogen generator designed and manufactured according to pressure swing adsorption technology. So, what factors will affect the stability of the nitrogen generator? From the composition of nitrogen generator, only two main factors affect its stability, namely control valve and carbon molecular sieve. The performance of PSA nitrogen generator: an excellent material, good sealing, no air leakage. It can accept frequent opening and closing actions to ensure the service life, and can quickly complete the switching action within receiving the control signal (about 0.02 seconds). The valve cycle (every 60 seconds) must open and close. The nitrogen generator works 300 working days a year, 24 hours a day. The adsorption and desorption cycle is 4 minutes, so each valve needs to be opened and closed more than 200,000 times per year. time. As soon as one of the valves fails, the entire plant is affected. Therefore, the continuous service life of the valve is an important part of the stability and reliability of the nitrogen generator.

How to Maintain an Industrial Oxygen Generator?

1. The outlet pressure of the filter pressure reducing valve is not within the normal range. At this time, it is necessary to adjust the filter pressure reducing valve. Adjustment method: Pull up the knob on the upper part of the filter pressure reducing valve, turn it clockwise to increase pressure, and turn counterclockwise to reduce pressure. When the required pressure is reached, press the knob to lock. The user should clean the filter body of the filter pressure reducing valve regularly to ensure air quality. Cleaning method: Rotate and pull down the bayonet cup at the bottom of the valve body, and clean the filter element and cup with a neutral detergent. The filter pressure reducing valve is an automatic drainage method, and the user should install the drainage pipe to an appropriate position. 2. During the regeneration process of the dryer, the pressure in the regeneration drying tower shall not exceed 0.02MPa. If it exceeds this value, after confirming that the valve is not faulty, it can be considered that the muffler is blocked. At this time, the muffler should be removed and the blockage should be cleared. If the blockage is severe and cannot be cleaned, the muffler should be replaced. 3. After the loaded desiccant has been running for a period of time, the drying bed will sink slightly, and the desiccant needs to be checked and refilled or replaced in time. The desiccant should be screened before loading to remove dust and make its particles uniform. 4. Regularly check the working status and sealing status of each valve. Regularly check whether the electrical components are in good contact, and often remove the dust inside and outside the distribution box. The above is the main content of how to maintain the industrial oxygen generator. Industrial oxygen generators are favored by the majority of users due to their remarkable advantages.

Precautions for the Purchase of Oxygen Concentrators

The oxygen generator is a machine that produces oxygen. The principle is to use air separation technology to first compress the air with high density, and then use the difference in the condensation point of each component in the air to separate it from the gas or liquid at a constant temperature. After rectification, it is separated into oxygen and nitrogen. Due to the widespread use of oxygen and nitrogen, oxygen generators have been widely used. Especially in metallurgy, chemical industry, petroleum, national defense and other industries, it is most widely used. 1. Industrial oxygen production equipment The principle of industrial oxygen production equipment is to use air separation technology to compress air with high density and separate gas and liquid at a specific temperature. Industrial oxygen is usually obtained through this physical method. 2. Medical oxygen production equipment All medical oxygen production equipment adopts the world's most advanced PSA (Pressure Swing Adsorption) air separation oxygen production technology. This is based on the difference in the adsorption capacity of the attractant (zeolite molecular sieve) for oxygen and nitrogen in the air to separate oxygen and nitrogen. When air enters the floor full of adsorbent, nitrogen has a strong adsorption capacity and is adsorbed, but does not adsorb oxygen, so a high concentration of oxygen can be obtained at the outlet end of the adsorption bed. 3. Household oxygen production equipment The adsorption performance of molecular sieve is based on physical principles. A large-displacement oil-free compressor is used as a power source to separate nitrogen and oxygen in the air to obtain high-concentration oxygen. This oxygen production mechanism has fast oxygen speed and high oxygen concentration, and is suitable for oxygen therapy and oxygen health care for all kinds of people. At present, the most common type of oxygen c

What are the Contents of Periodic Maintenance of Oxygen Production Equipment?

The maintenance of the equipment in the oxygen generation system mainly includes the maintenance of air compressors, refrigeration dryers, filters, and oxygen generators. The periodic maintenance of the oil screw air compressor is mainly the periodic replacement of the air inlet filter, as well as the replacement of the lubricating oil and oil separator every year. The maintenance of the compressor also includes regular oil replenishment and replacement (if necessary). In order to ensure the stable and reliable operation of the oxygen production system and the long-life operation of the compressor, the compressor must be maintained in accordance with the periodic maintenance methods and measures recommended by the compressor manufacturer. The periodic maintenance of the air-cooled refrigeration dryer is mainly to periodically purge and clean the sewage outlet; the water-cooled refrigeration dryer is to regularly clean the water condenser to prevent the clogging of scale deposits. Please carefully read the operation and maintenance manual of the refrigeration dryer, and strictly follow the periodic maintenance methods and measures recommended by the refrigeration dryer manufacturer to maintain the refrigeration dryer. The periodic maintenance of the filter is mainly based on the regular replacement of the filter element according to the use of the filter. If you find that the pressure difference of the filter is too large, please replace the filter element in time. Please refer to the periodic maintenance methods and measures recommended by the filter manufacturer for maintenance. Basically, the oxygen generator does not require periodic maintenance. The user can check whether the oxygen generator is operating normally once a year.

Analyze the Working Principle of Oxygen Generator Equipment

With the continuous improvement and improvement of people's economic living standards, the demand for health has gradually increased, and more and more people are actively buying oxygen generators for home oxygen therapy and health care. First, let us understand the important parameters of the oxygen concentrator. Before buying, please make sure that these important parameters meet your requirements. The main types of oxygen generator equipment What is an oxygen generator? As the name suggests, it is a machine that produces oxygen. At present, there are many types of oxygen generators on the market, but due to different oxygen evolution principles, their use characteristics are also different. According to the oxygen evolution principle of the oxygen generator, there are mainly molecular sieve principle, polymer oxygen-enriched membrane principle, electrolysis water principle, chemical reaction oxygen production principle, etc. The early principle of oxygen production was chemical oxygen production, that is, the use of chemical reagents to produce oxygen. This method cannot supply oxygen continuously for a long time, the chemical reagents are expensive, and the cost of oxygen production is high. This is excluded by the market. Molecular sieve oxygen generator is not only superior to other oxygen generators, because it is made of air and only consumes electricity, but also because the raw material is air, it does not need to be expensive, convenient, and inexhaustible. It is superior to liquid. Oxygen tank and cylinder oxygen. It also has the advantages of being easy to use and not being affected by factors such as market oxygen price increases and transportation costs. The molecular sieve oxygen generator device is currently the only mature oxygen generator with international and national standards. Therefore, it is recommended to buy an oxygen generator based on the principle of molecular sie

Air Separation Method Of Nitrogen Generator

Pure nitrogen cannot be directly derived from nature, so air separation is the first choice. Air separation methods include: cryogenic method, pressure swing adsorption (PSA), membrane separation method. With the rapid development of industry, nitrogen has been widely used in chemical, electronics, metallurgy, food, machinery and other fields. my country's demand for nitrogen is increasing at an annual rate of more than 8%. The chemical nature of nitrogen is not vivid, it appears lazy under ordinary conditions, and it is not easy to chemically react with other substances. Therefore, nitrogen is widely used as a maintenance gas and sealing gas in the metallurgical industry, electronics industry, and chemical industry. Generally, the purity of the maintenance gas is 99.99%, and some require high-purity nitrogen above 99.998%. Nitrogen generator liquid nitrogen is a relatively convenient cold source, and it has been more and more widely used in food industry, work, and animal husbandry semen storage. In the production of synthetic ammonia in the chemical fertilizer industry, if the raw material gas of synthetic ammonia-hydrogen-nitrogen mixed gas is washed and refined with pure liquid nitrogen, the content of inert gas can be extremely small, and the content of carbon monoxide and oxygen does not exceed 20 ppm. The above is about the difference between ventilators and oxygen concentrators. Our company has a large number of oxygen concentrators. If you are interested, you can come and have a look.

Process Flow of Industrial Oxygen Generator

After compressed by the air compressor, the air enters the air storage tank after dust removal, oil removal, and drying, and enters the left adsorption tower through the air inlet valve and the left inlet valve. The tower pressure increases, and the nitrogen molecules in the compressed air are zeolite With molecular sieve adsorption, the unadsorbed oxygen passes through the adsorption bed and enters the oxygen storage tank through the left gas production valve and oxygen gas production valve. This process is called left suction and lasts for tens of seconds. After the left suction process is over, the left adsorption tower and the right adsorption tower are connected through a pressure equalizing valve to balance the pressure of the two towers. This process is called pressure equalization, and the duration is 3 to 5 seconds. After the pressure equalization is over, the compressed air enters the right adsorption tower through the air intake valve and the right intake valve. The nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve, and the enriched oxygen enters the oxygen storage through the right gas production valve and oxygen gas production valve. Tank, this process is called right suction, and the duration is tens of seconds. At the same time, the oxygen adsorbed by the zeolite molecular sieve in the left adsorption tower is released back to the atmosphere through the left exhaust valve. This process is called desorption. On the contrary, when the left tower is adsorbing, the right tower is also desorbing at the same time. In order to completely discharge the nitrogen released f

Not only that, in order to reflect the diversification of our business, we also have SMT Cleaning Machine, PCB Cleaning Machine, PCB Separator, Reflow / Wave Soldering Machine, SMT Nozzle / Feeder.Next, I will introduce the classification of nitrogen generators. 1. Cryogenic Air Separation Nitrogen Generator: Cryogenic Air Separation Nitrogen Generator is a traditional nitrogen production method with a history of several decades. Air is used as raw material, compressed and purified, and the air is liquefied into liquid air through heat exchange. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. The boiling point of liquid oxygen and liquid nitrogen is different (under 1 atmosphere, the boiling point of the former is -183 and the boiling point of the latter is -196), and nitrogen is separated by liquid-air rectification. Cryogenic batch nitrogen production equipment is complex, covers a large area, high construction cost, one-time investment in equipment, high operating cost, slow gas production (12) 24h), high installation requirements, and long cycle. Comprehensive equipment, installation and construction of many factors, equipment below 3500Nm3/h, the investment scale of PSA devices of the same specification is 20% to 50% lower than that of cryogenic air separation devices. The cryogenic split nitrogen production device is suitable for large-scale industrial nitrogen production, but it is not economical for medium and small-scale nitrogen production. 2, mo

Use Cases of Oxygen Generator Equipment in the Breeding Industry

Oxygen concentrators are generally considered to be more medically used. However, in daily life, oxygen concentrators are also used more frequently. The most common ones are small oxygen concentrators used by pregnant women and small oxygen concentrators used by the elderly. But today I To talk about the oxygen generators used in our industry, which industries are industrial oxygen generators mainly used for? 1. Breeding oxygen generators: generally used in the breeding industry. For example, fish and shrimp lack of oxygen in the water can be solved by the oxygen generator's oxygen. Breeding species in the plateau are like pigs, cattle and sheep. They generally suffer from insufficient oxygen absorption on the plateau. Equipped with oxygen generator equipment, can better increase production, 2. Industrial oxygen generators are used in the chemical industry: the general use of industrial oxygen generators is still conventional. Industrial oxygen generators are mainly used for the combustion of chemical products and combustion in the glass industry. After the glass is dissolved at the high temperature of the oxygen generator Pour into the designated custom container, so as to form our common crafts in life. 3. Plateau oxygen concentrator: In plain areas, we cannot feel the uncomfortable lack of oxygen in the plateau, but there will be altitude sickness in the plateau area. Many tourists will feel unwell after arriving at the site. Therefore, it is necessary to configure the plateau oxygen concentrator equipment. The plateau oxygen concentrator produced can be widely used in the hypoxia caused by insufficient oxygen content in the plateau area. For example, hotels in the plateau area can use the Shenyue Plateau oxygen concentrator equipment, so that our plain area travel to the plateau will be omitted. A lot of trouble! There are many applications of oxygen generators. Like the recent new crown virus, the dema
