The utility model discloses an apparatus for recovering potential heat from alcohol screenings. The utility model is characterized in that a screening discharging opening of a topping still is communicated with a buffer tank, and the top of the buffer tank is communicated with the topping still; the bottom of the buffer tank is communicated with a first stage vacuum tank, and the first stage vacuum tank and a second stage vacuum tank are respectively communicated with a first stage jetting pump and a second stage jetting pump; the first stage jetting pump and the second stage jetting pump are respectively communicated with a steam source, and the first stage vacuum tank and the second stage vacuum tank are communicated through a U-shaped pipe; an outlet of the first stage jetting pump and an outlet of the second stage jetting pump are communicated with the topping still; the bottom end of the second stage vacuum tank is communicated with an alcohol screening pool after the bottom end of the second stage vacuum tank passes through a liquid sealing tank. Through the utility model, heat energy in the alcohol screenings, which is discharged by the topping still, can effectively return to the topping still to be recovered and utilized for realizing the task of energy saving.
