psa nitrogen machine core performance:

Properties of carbon molecular sieves: B. nitrogen production A hardness (m3 / TH) C recovery (N2 / air) % bulk density. The above indicators have been in the factory logo, but only as a reference data, how to maximize the efficiency of carbon molecular sieve, this process of nitrogen manufacturers and adsorption ratio has a direct relationship, in ensuring the service life of molecular sieve is very important:

Filling carbon molecular sieve technology: the adsorption tower of carbon molecular sieve must have a special filling technology, otherwise it is easy to powder and lead to failure, we can find in this process, when compressed air from the bottom of the high-speed adsorption tower, if there is no special gas distributor,

Through the influence of air, the molecular sieve is easily caused by friction, molecular sieve powder. In the adsorption tower molecular sieve is not tight, after a period of use, the zeolite subsidence slowly decreases, the gap between the molecular sieve, if there is no automatic filling device and compression device, the adsorption tower will appear obvious space. When the compressed air enters the lower part of the tower adsorption, the molecular sieve will impact the flow, in a very short period of time rapid displacement occurs, the molecular sieve due to collision, friction and collision, adsorption of the tower wall, it is easy to make the molecular sieve powder failure.

The effect of oil, gas and water on molecular sieve: because the air contains water and oil, after the compressor, if there is no strict air purification treatment, oil and water carbon molecular sieve adsorption, desorption and difficulty in filling the molecular sieve pore size, molecular sieve due to "poisoning" failure. Therefore, a strict air purification device is set up before the compressed air enters the adsorption tower, which is an important molecular sieve for the service life of the ring. In molecular sieve water, although not fatal, but the molecular sieve adsorption load increases, affects the adsorption capacity of O2, CO2, so that the compressed air dry water removal, is to improve the sieve adsorption capacity and stability of the molecules can not be ignored.
