How To Filling Molecular Sieve And Activated Alumina? Xintao provides you with the precautions for loading molecular sieves and activated alumina
If you are a user using an adsorption dryer, you should pay attention to the following points when filling on site:
- The original adsorbent (the absorbent is generally two types of absorbents, activated alumina and molecular sieves) must be cleaned up. There is no residual adsorbent in the adsorption tower.
- During the filling, the method of “vibration filled” plus “layered tiny” method. The specific operation can be filled with one side to vibrate the tower wall to ensure that the adsorbent is filled with densely.
- Check the inspection after the filling, and you cannot leave the corner of the dead. Pay special attention to the fillers and places where the attached tower is attached.
- It can be added once every 5-7 days. (If the filling volume of the device is less than 1000kg, it is necessary to add it every 30 days. If the filling amount is less than 500kg, it can be divided into three supplements. Seven, 30 days, and 45-60 days are checked and filled 3 times respectively. This can indeed ensure the use time and effect of activated alumina).
Material of particles, with the increase in running time, the density of the adsorbent will increase, so that the gap will occur in the adsorption tower. Once the gap appears, the adsorbent will produce friction in the adsorption tower. Fan phenomenon, if it is not treated in time, will become more and more serious, resulting in the blockage or damage of subsequent accessories.
Summary of Precautions for Loading Adsorbent into Dryer
The filling of molecular sieve and alumina adsorbent shall follow the principle of uniformity, compactness and no dead corner. Uneven filling is easy to generate air flow “tunnel” in the adsorption cylinder, which shortens part of the compressed air and affects the air dew point. The method of “vibrating filling” and “layered tamping” is generally used to fill the adsorbent in the factory, and the operation results can basically meet the requirements.
The best way to remedy the filling defects of adsorbent is to supplement it on site after a period of use.
