Abstract
A kind of glycerine rectifying distilling apparatus, relate to rectification process technical field, comprise destilling tower, reboiler, the first and second storage tanks, first, second, and third packing layer is set in destilling tower from the bottom to top, first group, second group and the 3rd group of distributor are set respectively above first, second, and third packing layer; The first product collector is set below the second packing layer, below the 3rd packing layer, the second product collector is set; The lower end of reboiler is connected by circulating line with the cavity bottom of the lower end of the first packing layer at destilling tower, and the cavity top of the upper end of reboiler and the lower end of the first packing layer is connected by another pipeline.Crude glycerine upwards successively by first, second, and third packing layer, just can collected and obtain the glycerine sterling that rectifying goes out at the bottom of the tower of destilling tower below the second packing layer.The utility model can be saved energy consumption greatly, reduces production costs, and the quality of the glycerine that rectifying is made is improved, and content reaches more than 99.5%.
Description
Technical field
The utility model relates to the rectifying of rectification process technical field, particularly glycerine with structure technology is set.
Background technology
In the tower of existing glycerol distillation tower, establish reboiler, tower peripheral hardware return tank arranges respectively from the bottom to top three layers of filler in destilling tower, and three layers of filler all adopt 304 stainless steel metal structured packings.
Crude glycerine is carried out to refining distillating method is: at the bottom of liquid phase glycerine is pumped into destilling tower, in tower, directly with reboiler, liquid phase glycerine is changed into gas phase glycerine, temperature is that the gas phase glycerine of 180～200 DEG C passes three layers of filler in destilling tower, arrive overhead condenser, after overhead condenser condensation, enter return tank, a return tank part refluxes, a part gathers, and what gather out is refining glycerine.
Above distillating method can make to distill glycerine institute calorific requirement and increase, and causes distilling column bottom temperature and raises, and temperature raises favourable to forming polyglycerol, can make like this glycerine level of residue increase, and reduces the production capacity of smart glycerine.
Utility model content
The utility model object is a kind of glycerine rectifying distilling apparatus that proposes to overcome above prior art defect.
The utility model comprises destilling tower, reboiler, the first storage tank and the second storage tank, and the first packing layer, the second packing layer and the 3rd packing layer are set respectively from the bottom to top in destilling tower, at the top of destilling tower, vacuum access port is set; It is characterized in that: first group of distributor is set above the first packing layer, second component cloth device is set above the second packing layer, the 3rd group of distributor is set above the 3rd packing layer; The first product collector is set below the second packing layer, below the 3rd packing layer, the second product collector is set; Described reboiler, the first storage tank and the second storage tank are separately positioned on outside destilling tower; The lower end of described reboiler is connected by circulating line with the cavity bottom of the lower end of the first packing layer at destilling tower, and the cavity top of the upper end of reboiler and the lower end of the first packing layer is connected by another pipeline; Between one end of the first storage tank and the first product collector, connecting pipe is set, connects another pipeline at the other end of the first storage tank by threeway, the other end of this pipeline is connected to the entrance point of first group of distributor; Between one end of the second storage tank and the second product collector, connecting pipe is set, be connected to one end of one group of condenser at the other end of the second storage tank, the other end connecting tee of condenser, another two interfaces of threeway are connected by the distributor entrance point of pipeline and second component cloth device and the 3rd group respectively.
In three layers of packing layer, add respectively corresponding filler, content is not less than to 90% crude glycerine and is warming up to after 155～160 DEG C at the bottom of the tower of destilling tower upwards successively by the first packing layer, the second packing layer and the 3rd packing layer, just can obtain the glycerine sterling that rectifying goes out in collection below the second packing layer.The utility model advantage is mainly manifested in the following aspects:
1, the column bottom temperature of distillation significantly reduces, and can greatly save energy consumption, reduces production costs.
2, glycerine production capacity increases substantially.
3, due to the design of above technique, the diameter of destilling tower and height can significantly decline, and reduce glycerine vaporization height, reduce the glycerine required energy consumption of vaporizing.
4, owing to adopting special filler, make the pressure drop of tower top and tower top remain on less scope, make vacuum at the bottom of destilling tower remain on-more than 0.092.
The quality of the glycerine that 5, rectifying is made is improved, and content reaches more than 99.5%.
