Nitrogen generators have many names, such as nitrogen generators, nitrogen generators, nitrogen generators, nitrogen generators, etc. There are also several conventional production technologies, generally pressure swing adsorption and membrane separation technology. Process flow of nitrogen generating device The compressed air provided by the air compressor is treated by the air purification system and enters the pressure swing adsorption nitrogen generating device for oxygen and nitrogen separation. Normally, qualified nitrogen can be obtained.
When it comes to customized nitrogen generators, which route do you choose? Is it PSA pressure swing adsorption or membrane separation technology? Regarding how to choose a nitrogen generator (also known as a nitrogen generator), which nitrogen generation technology is the best?

It can be said that at present, from a technical point of view, there are basically three nitrogen production technologies for nitrogen generators, including carbon molecular sieve pressure swing adsorption, hollow fiber membrane separation method, and electrochemical nitrogen production method. These three technologies have their own advantages and disadvantages. More broadly, there are two types of PSA pressure swing adsorption and membrane separation. Nitrogen generators (also known as nitrogen generators) use more of these two technologies. Today, I will share with you the nitrogen-generating principles of these two technologies and their respective characteristics. If there is any inaccuracy, please leave a message to add. : Pressure swing adsorption technology Pressure swing adsorption is a nitrogen production technology that uses air as raw material and carbon molecular sieve as adsorbent. It is a kind of porous and loose carbon particles. When compressed air passes through carbon molecular sieve, different gas molecular diameters and The molecular properties of the gas itself will be adsorbed by carbon molecular sieve, such as water vapor and oxygen in the air, but nitrogen will not be adsorbed, so as to achieve the purpose of being separated and collected; the process of pressure swing adsorption is adsorption decompression-re-adsorption decompression process of rebirth. Membrane separation technology However, membrane separation technology also uses air as raw material. Compressed air passes through hollow fiber membranes. Due to the different molecular diameters of different gases, when air passes through the membrane, oxygen, carbon dioxide and water vapor with smaller molecular diameters will pass through the hollow fiber membrane. Small holes in the pipe, and then exhaust to the atmosphere. At the outlet of the membrane, nitrogen molecules with large molecular diameters and inert gas argon are collected to complete the nitrogen extraction process.
Comparing the two technologies of nitrogen generator:
1. Purity nitrogen plays different roles in different analytical instruments, so the requirements for purity are also different. Under the same conditions, such as intake air volume, pressure, gas source quality, filtration system, etc., pressure swing adsorption can achieve The purity of the membrane separation technology is much higher than that of the membrane separation technology; the current market technology membrane separation technology has a purity of 99.5%, and the carbon molecular sieve pressure swing adsorption can basically reach the purity of 59, which is infinitely close to the cylinder gas.
2. Flow rate and volume size Regardless of whether it is a nitrogen generator using carbon molecular sieve or membrane separation technology, its size is related to the nitrogen flow rate. Predominant, if the flow rate is large, the pressure swing adsorption of molecular sieve should be more dominant.

3. Dew point or water content From the theoretical point of view, the water removal ability of pressure swing adsorption is better than that of membrane separation. For pressure swing adsorption of carbon molecular sieve, if the front-end treatment is improper, not only the water removal ability will decrease, but also the carbon molecular sieve will be pulverized. Weakening or even losing the adsorption capacity. For membrane separation, it is particularly afraid of water and oil. If the fiber membrane is not handled properly, the adsorption capacity will also be lost, and the fiber membrane must be discarded.
4. The noise is between PSA pressure swing adsorption or membrane separation nitrogen production technology, which uses air source as raw material to extract nitrogen, so it is the same in terms of noise or air compressor maintenance, and the quality may depend more on the air quality of the compressor.
Laboratory nitrogen generator custom price Nitrogen generators are more and more used in all walks of life, which is the result of the upgrading and substitution of the industrial chain; the role of nitrogen: often used as a protective gas to prevent certain objects from being exposed to oxygen by oxygen Oxidation can make the grain not rotten and germinate, and it can be stored for a long time. In industry, it is used as a protective gas for laser welding, integrated circuits, heat treatment metallurgy, etc. Compared with traditional steel cylinders, nitrogen generators are more convenient and safer. Needless to say, many styles have different purities and dosage configurations for various industries and industries. The price is as high as hundreds of thousands, which is a pressure for the use cost of small enterprises. , The application of small nitrogen generators in our lives has gradually increased. Now as long as it is a commodity, it needs to be packaged, and nitrogen-filled packaging has become the main packaging method. Packaging machinery makes our packaging attractive, and miniature nitrogen generators are more Make our products more secure. Now with the fierce social competition, people also put forward higher requirements for the performance of micro nitrogen generators, and efficient equipment is more favored by customers. It also makes up for the deficiencies of many packaging methods. So how does our micro nitrogen generator conquer our customers? The micro nitrogen generator is an ideal choice for many enterprises, because the equipment is small in size, small in gas volume, low in energy consumption, fast in nitrogen production, and very convenient for installation and maintenance. , favored by all walks of life
