Notice of Adsorbent in Pressure swing adorption:
The adsorbent should have the characteristics of being porous, strong in activity, strong in acid absorption, etc., in order to adsorb moisture, peroxygen compounds, organic acids, hydroxyl groups, etc. in the oil, which are harmful to the transformer and the oil. The commonly used and inexpensive ones are acid-free silica gel (coarse, fine-pored silica gel) and activated alumina. They are spherical and rod-shaped irregular porous solid materials, and have the following requirements for their properties. Therefore, before the adsorbent is added to the oil purifier, it should be dried and sieved.
The amount of adsorbent is determined by the total mass of the oil. When using silica gel, it is about 0.75%-1.25% of the total mass of the oil, the smaller capacity transformer uses a large number; the large container transformer uses a small number. At the time, when using activated alumina, it was about 0.5% of the total mass of the oil.
