Minnuo, on-site PSA nitrogen generator manufacturer and supplier leader in China, has 36 years of experience in PSA nitrogen generator system and equipment, served more than 2,000+ nitrogen generator equipment, we can provide molecular sieve with purity up to 99.9997% purity up to 10 years warranty and 20 years warranty for main valve equipment.
PSA full name: Pressure Swing Adsorption, PSA is a new gas separation technology, the principle is to use the molecular sieve on the different gas molecules “adsorption” performance differences in gas mixtures will be separated, which is based on the air as raw material, the use of a high-efficiency, high-selective solid adsorbents It takes air as raw material and utilizes a high-efficiency and highly selective solid adsorbent to selectively adsorb nitrogen and oxygen to separate the nitrogen and oxygen in the air.
PSA nitrogen gas generator takes clean compressed air as raw material and carbon molecular sieve as adsorbent, and utilizes the principle of variable pressure adsorption to obtain nitrogen at room temperature. According to the difference of the adsorption amount of oxygen and nitrogen in the air on the surface of carbon molecular sieve and the diffusion rate of oxygen and nitrogen in the carbon molecular sieve, the opening and closing of the programmable controller controls the programmed valve, realizing the process of adsorption under pressure and desorption under reduced pressure, completing the separation of oxygen and nitrogen, and obtaining the nitrogen with the required purity.
Nitrogen generator is based on the principle of variable pressure adsorption, using high quality carbon molecular sieve as adsorbent, and extracting nitrogen from air as raw material under certain pressure. The purified and dried compressed air is adsorbed under pressure and desorbed under reduced pressure in the adsorber. Due to the aerodynamic effect, the diffusion rate of oxygen in the micropores of the carbon molecular sieve is much larger than that of nitrogen, and oxygen is preferentially adsorbed by the carbon molecular sieve, while nitrogen is enriched in the gas phase to form finished nitrogen. Then after depressurization to atmospheric pressure, the adsorbent desorbs the adsorbed oxygen and other impurities to realize regeneration. Generally, two adsorption towers are set up in the system, one tower adsorbs nitrogen, the other tower desorbs and regenerates, and the opening and closing of the pneumatic valve is controlled by PLC program controller, so that the two towers circulate alternately to realize the purpose of continuous production of high-quality nitrogen.
PSA on-site nitrogen generator has the features of simple process, high degree of automation, fast gas production (15-30 minutes), low energy consumption, product purity can be adjusted according to user’s needs in a wide range, easy operation and maintenance, low operation cost, and strong adaptability of the device, etc. Therefore, it is quite competitive among the nitrogen generating equipments below 1,000Nm3/h, which is more and more welcomed by the medium-sized and small-sized nitrogen users, and the PSA nitrogen generator has become the preferred method of medium-sized and small-sized nitrogen users.
The drilling and milling machine has advanced and reasonable structure, light and flexible operation, easy maintenance, and can generally meet the requirements of IT8 level accuracy and roughness.
