How to solve the problem of carbon molecular sieves constantly emitting ash?
一. The necessity of ash spraying treatment
Ash spraying not only leads to a decrease in nitrogen purity, affecting subsequent production processes, but also poses potential damage to equipment. For example, in the filter screen of a nitrogen generator, if carbon molecular sieves that have been used for a long time are not promptly treated, the ash they produce may clog the filter, thereby reducing the efficiency of the equipment. In severe cases, it may also cause equipment failure, increase maintenance costs, and reduce production safety.
二、Common methods for ash spraying treatment
1. Regular replacement of carbon molecular sieves: Maintaining the normal operation of the equipment, regular replacement or cleaning of carbon molecular sieves is an effective preventive measure.
2. Utilizing high-temperature cleaning: Heating the carbon molecular sieves at a certain temperature can effectively remove the impurities adsorbed, but attention should be paid to temperature control to avoid damaging the sieve body.
3. Improving the filtration device: Setting up an anti-ash-spraying filtration device during nitrogen production and adding additional physical filtration steps to improve the purity of nitrogen.
4. Optimizing process parameters: Adjusting the inlet flow rate, pressure, etc. according to production needs and equipment characteristics to reduce the generation of ash.
