    refrigerated and adsorption type air dryer Compressed air treatment Hongjinli

    Adsorption Air Dryer

    Freezing-adsorption combined air dryer Hongjinli Company's BC series energy-saving freezing-adsorption combined low dew point compressed air drying device is a new type of compressed air drying device. It is an organic combination of a freezing dryer and a microthermal regeneration dryer. The two There is a close and inseparable internal connection with the word flow setting.
    The combined dryer adopts the newly developed drying process. It is different from the simple process of connecting a cold dryer and an absorbing dryer in series. The process flow is: the air compressor sends compressed air through the rear cooler, and the first choice is to change the drying process. It exchanges heat with the dried low-temperature compressed air in the heater to lower the temperature, and then enters the evaporator to be further cooled to about 2°C. At this dew point, most of the water in the compressed air has become liquid and is discharged, reducing the water content to very little. The compressed air enters the adsorption tower for further drying and water removal. Finally, the low-temperature dry compressed air enters the heat exchanger to cool the high-temperature humid air. At the same time, its temperature also rises, which can prevent condensation on the outer wall of the compressed air delivery pipeline. After heating, A small part of the compressed air is used as regeneration gas for the adsorbent to improve regeneration efficiency and reduce energy consumption.
