Abstract: An air-liquid separating method and apparatus for compressed air. The high pressure air output from an air compressor is transferred through a transfer tube to pass through the cooling tube of a cooling tank. The cooling tube has a diameter larger than that of the transfer tube so that the high pressure air goes from a smaller room into a larger room and the pressure is relieved. The temperature of the high pressure air is lowered due to relief of the pressure and the pressure of the vapor is, approximately the saturated vapor pressure. The cooled high pressure air is further transferred to an air-liquid separating tank. The temperature of the air is lowered to the dew point due to further relief of pressure. At this time, the vapor contained in the high pressure air is condensed into liquid water which drops onto the bottom of the air-liquid separating tank and separates from the air.
