Specific embodiment
A kind of glycerol distillation device of the utility model is made further specifically with reference to the accompanying drawings and detailed description
It is bright.
Shown in Fig. 1, a kind of glycerol distillation device of the utility model includes destilling tower 1, hot water storgae 6 and overheats sink 7, described
Upper heat exchanger 2, lower heat exchanger 3, upper take-up reel 4 and lower take-up reel 5 are equipped in destilling tower 1；The import and heat of the upper heat exchanger 2
The outlet at bottom pipeline of sink 6 is connected, and outlet is connected with the top entry pipeline of hot water storgae 6；The import of the lower heat exchanger 3 with
The outlet at bottom pipeline for overheating sink 7 is connected, and exports and is connected with the top entry pipeline of overheat sink 7；The upper take-up reel 4 is set
