It is novel, it is not intended to limit the scope of the utility model.
A kind of recoverable apparatus for mixed solvent, including raw material storage tank 1, distillation still 2 and distillate drum, the distillation still
2 are located at the right side of raw material storage tank 1, and the distillate drum is located at the upper right side of distillation still 2, sets between the distillation still 2 and distillate drum
There is rectifying column 4,4 upper end of rectifying column is connected with collector 5, and 5 upper end of collector, which is connected with, collects device 6, the rectifying
Cooler 7 is connected between tower 4 and fraction tower, the fraction tower includes tails tower 8, front-end volatiles tower 9 and filtering fraction tower 10.
Agitating shaft 11 is equipped with inside the distillation still 2, the agitating shaft 11 uses explosion-proof agitating shaft.
Centrifugal pump first 12 is connected between the raw material storage tank 1 and distillation still 2.
The tails tower 8, front-end volatiles tower 9 connect and connect the lower end of cooler 7, institute with the upper end of filtering fraction tower 10
The lower end connection distillation still 2 of tails tower 8 is stated, 9 lower end of front-end volatiles tower is connected with centrifugal pump second 13, the filtering fraction tower
