The nitrogen generator produced by Huitong Xinda adopts the principle of pressure swing adsorption. The molecular sieve nitrogen generator uses clean compressed air as the raw material and carbon molecular sieve as the adsorbent. It uses the principle of pressure swing adsorption to obtain nitrogen at room temperature. Molecular sieve nitrogen generators generally use PSA carbon molecular sieve as the adsorbent. The adsorption speed of carbon molecular sieve to oxygen and nitrogen varies greatly.
A large amount of adsorption, but little adsorption of nitrogen molecules, using this feature to complete the separation of oxygen and nitrogen. The adsorption capacity of carbon molecular sieve to oxygen decreases with the decrease of pressure. When the pressure is reduced, the adsorbed oxygen molecules escape from the carbon molecular sieve, enter the muffler through the lower part of the tower, and then discharge into the atmosphere to desorb and complete the regeneration of carbon molecular sieve. . In addition, carbon molecular sieves also have the ability to adsorb carbon dioxide and water, and are easier to decompress and desorb. Usually, the PSA nitrogen generator adopts double adsorption parallel connection alternately to generate nitrogen by adsorption, desorption and regeneration, realizes the separation of oxygen and nitrogen, and continuously supplies gas.
Since nitrogen is widely used in chemical production, Huitong Xinda continues to improve the production and supply methods of nitrogen to improve the efficiency of chemical processing, reduce costs, and make applications easier. Now, Huitong Xinda has developed various forms of nitrogen generators, which can meet the requirements of different users, including the requirements of purity, gas consumption, mobility, floor space and energy consumption.
