When the carbon molecular sieve is loaded into the adsorption tower, special filling technology must be adopted, otherwise it is easy to pulverize and lose efficacy. From the process, we can see that in the process of entering compressed air at high speed from the bottom of the adsorption tower, due to the lack of special gas distribution device, the molecular sieve is strongly impacted by the air flow, resulting in friction, which is easy to cause the pulverization of molecular sieve.
In addition, it is impossible for molecular sieves to be completely packed in the adsorption tower. After using for a period of time, the gap between molecular sieves will gradually narrow and sink slowly. If there is no automatic filling device and pressing device, obvious gaps will appear on the upper part of the adsorption tower. With the compressed air entering the lower part of the adsorption tower, the molecular sieves move rapidly in a short time under the impact of the air flow, causing the molecular sieves to collide and rub with each other, and collide with the wall of the adsorption tower, so that the pulverization of molecular sieves is invalid.
