Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It further include that liquid feeding pump 1, condensed water are pre- refering to Figure 1, a kind of energy-saving rectifying tower, including rectifying column main body 14
Hot device 3, reboiler 7, separator 8, raffinate preheater 9, stripping tower 12, distributor 13, condenser 16, recooler 17, cooler
18, liquid feeding pump 1 connect by inlet tube 2 with the inlet of condenser 16, the liquid outlet of condenser 16 pass through materail tube 1 and
The upper end import of raffinate preheater 9 connects, and raffinate preheater 9 is connect with separator 8, and 9 side wall of raffinate preheater is equipped with raffinate
The lower end outlet of delivery pipe 10, raffinate preheater 9 is connect by materail tube 26 with the lower end import for condensing water preheater 3, is condensed
3 upper end of water preheater is equipped with condensate pipe 4, and the upper end outlet of condensation water preheater 3 passes through materail tube 35 and 13 side wall of distributor
Import connection, 13 lower end of distributor are equipped with stripping tower 12, and 12 lower end of stripping tower is equipped with separator 8, and separator 8 and reboiler 7 connect
