Performance of carbon molecular sieve: B. nitrogen production a hardness (m3 / th) C recovery (N2 / air)%, bulk density. The above indicators of carbon molecular sieve manufacturers have been marked in the factory, but only as a reference data. How to maximize the efficiency of carbon molecular sieve is directly related to the nitrogen manufacturer and the ratio of height to diameter in this process, which is very important in ensuring the service life of molecular sieve
Technology of filling carbon molecular sieve: the adsorption tower of carbon molecular sieve has a special filling technology, otherwise it is easy to powder and cause failure. We can find that in this process, when the compressed air flows from the bottom of the high-speed adsorption tower, if there is no special gas distributor,
Through the influence of air, friction of molecular sieve, easy to cause molecular sieve powder. When the molecular sieve in the adsorption tower is not tight, after a period of use, the zeolite sinking slowly decreases, and the gap between molecular sieves, if there is no automatic filling device and pressing device, the adsorption tower will appear obvious space. When the compressed air enters into the lower part of the tower for adsorption, the molecular sieve will impact force flow and move rapidly in a very short time. Because of collision, friction, collision and adsorption of the tower wall, the molecular sieve powder is easy to fail.
Influence of oil, gas and water on Molecular Sieves: due to the presence of water and oil in the air, if there is no strict air purification treatment after the compressor, the oil and water carbon molecular sieves will be adsorbed, desorbed and difficult to fill the pore size of molecular sieves, and the molecular sieves will fail due to "poisoning". Therefore, the strict air purification device is set before the compressed air enters the adsorption tower, which is an important molecular sieve with long service life.
In molecular sieve water, although not fatal, but molecular sieve adsorption load increase, affect the adsorption capacity of O2, CO2, make compressed air dry to remove water, is to improve the adsorption capacity and stability of molecular sieve can not be ignored.
