In order to achieve the above object, the utility model has been taked following technical scheme: a kind of energy-saving distilling tower, and this energy-saving distilling tower is combined by the boiler of two or more destilling towers and heating conduction oil; Destilling tower is made up of body of the tower, tower courage distilling apparatus and tower bottom heating device, its tower courage distilling apparatus is linked in sequence by the alcohol input and output channel respectively, its tower bottom heating device forms the loop by conduction oil input and output channel and boiler, it is characterized in that: described destilling tower is connected with cooling tower by the alcohol efferent duct, and the cooling tower bottom is connected with next destilling tower by the alcohol input pipe.
Described destilling tower tower bottom heating device is a tubular structure.
Described destilling tower comprises wine with dregs tower, aldehyde tower and the rectifying column that is linked in sequence.
Alcohol input and output channel between described wine with dregs tower and the aldehyde tower, between aldehyde tower and the rectifying column is provided with cooling tower.
Described cooling tower is provided with one-level or more than the one-level.
Described rectifying column top is connected to form the loop by alcohol output intake line and cooler.
Described wine with dregs tower is provided with feeding mouth, and rectifying column is provided with alcohol finished product efferent duct.
The utility model adopts multi-tower structure, alcohol raw material enters destilling tower from top to bottom from feeding mouth, heating is from bottom to top, so the sinking of the raw material of the destilling tower by layer by layer and constantly heating, there is not the loss heat, reached the purpose of distillation layer by layer, improved the utilization rate of heat energy, moreover, also be not easy evaporation because conduction oil is not easy heat radiation, almost there is not heat energy loss, 250 ℃ of boiler control conduction oil temperature, and 100 ℃ of temperature that alcohol distillation needs, 170 ℃ of last waste heat return boiler temperature, therefore 1 ton of alcohol of the utility model production only consumes about 0.5 ton of coal, save greatly and use coal, the about 40-50% of electricity reduces waste water simultaneously, the liquid waste processing expense, thus production cost reduced, and conduction oil has significantly reduced the service life of using the dangerous of boiler and having improved boiler as heater.
