The utility model relates to a drainage apparatus for a refrigerating-type compressed-air drying machine, which is composed of a drain outlet connected with a pipeline of a drying machine, a water storage tank, a front valve positioned between the drain outlet and the water storage tank, a back valve positioned on the water storage tank and the water outlet, and a control device for controlling the time sharing start and stop of the front valve and the back valve, wherein, the control device comprises a central processing unit, a detection circuit for the liquid level of the drain outlet and an acoustic-optic alarm circuit; the control device can carry out the timing and can alternatively control the start and the stop of the front and the back valves, for eliminating condensed water in the type of segments; the leakage of the compressed air can be avoided. When the water outlet is blocked, the detection circuit for the liquid level can start the alarm circuit through the central processing unit.
