<p><P>PROBLEM TO BE SOLVED: To provide an air dryer provided with an oil-water separation apparatus and which is space-saving type, low cost, and convenient for use and is capable of saving the energy by recycling waste heat in the apparatus as a heat source for vacuum distillation. <P>SOLUTION: This air dryer is a refrigeration type air dryer for cooling compressed air in a heat exchanger and compressing water contained in the compressed air as drain to be separated from the compressed air, and the air dryer is provided with an oil-water separation apparatus which is capable of evaporating and separating water in the drain from oil components by heating the drain from the heat exchanger in a reduced pressure in a vacuum distillation tank connected to the heat exchanger and recovering the evaporated water as purified water. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
