Dry Air Generator



Dry air generator is suitable for providing dry air required during maintenance of large power equipment such as transformers and reactors in power systems, and can replace the traditional hot oil circulation drying method for transformers. It is also suitable for air drying and circulating drying in warehouses, packaging, electronics and other industries. In addition, it is particularly suitable for drying hydrogen in the hydrogen cooling system of generator sets, as well as drying SF6 gas in SF6 equipment. AD dry air generator for power equipment maintenance is not affected by changes in external climatic conditions. Especially for overnight operations, just seal the flanges and fill with dry air at 0.02-0.03Mpa, and transformers and reactors without oil injection will not be affected by moisture. This reduces the workload of daily oil extraction and injection, achieving the effect of shortening maintenance cycles and improving maintenance quality. During the oil filtration process, the equipment box and oil can be inflated and dried. When filtering oil in rainy or humid environments, it can ensure the improvement of oil insulation and reduction of moisture. When idle, it can be used as an indoor air conditioner at the construction site.



1. Product Introduction



      Dry Air Generator is specially designed to provide high-purity dry air with a dew point as low as -40℃ to -70℃ for large power equipment such as transformers and reactors during installation and maintenance. It can replace traditional drying methods such as hot oil circulation, nitrogen supplementation, and vacuum extraction, and is more efficient, economical, safe, and environmentally friendly. It comprehensively utilizes the advantages of cold dryers, adsorption dryers, coalescing oil-water separators, and ultra-precision filtration, scientifically combining the three drying and purification processes of freezing, adsorption, and filtration. Through reasonable pipeline connections and capacity matching, it achieves optimal economic operation and produces high-quality dry air with low dew point. Moreover, with integrated design, PLC automatic control, automatic detection of various operating parameters, compact and reasonable structure, good drying effect, low regeneration gas consumption, long working life, and effective use of composite desiccants, its service life is more than three times longer than ordinary adsorbents. It adopts microcomputer program control, which is efficient, energy-saving, safe, and reliable.



2. Working Principle



      Atmosphere enters the air storage tank through the air compressor, most of the moisture is compressed and liquefied and discharged through the drain valve, and the air undergoes the first drying; then it enters the refrigerated dryer, where water vapor is condensed into water, and the air undergoes the second drying; then it enters the adsorption dryer for the third drying, adsorbing the remaining trace moisture, and finally passes through a high-precision air filter and is transported to the equipment requiring dry gas.
