The compressed air enters the interior of the device and is first subjected to an internal condensation treatment. A plurality of copper tubes are installed inside the condensation chamber, and a condensation tube is installed inside the copper tube to reduce the internal temperature. When the compressed air passes through the condensation chamber, the low temperature condenses the moisture inside the compressed air. The condensed moisture is retained on the surface of the copper tube and then discharged from the drain port. After the compressed air is initially condensed, it is subjected to an oil removal treatment and then transmitted to a mixing chamber. Dry compressed air is continuously input into the mixing chamber to mix with the condensed compressed air, so that a small amount of moisture retained inside is removed, thereby increasing the drying effect of the compressed air.

In order to increase the oil removal effect, after secondary treatment, multiple cold liquid plates are installed inside the oil removal bin. The interior of the cold liquid plates is filled with coolant and vents are opened. Oil absorption layers are installed between the cold liquid plates. When the compressed air passes through, the internal oil is absorbed to increase the treatment effect of the compressed air. BRIEF DESCRIPTION OF THE DRAWINGS
