Description
Technical field
This utility model relates to xylitol preparation field, is specially a kind of xylose desalination and concentration device.
Background technology
Xylitol is a kind of sweet substance with nutritive value, is also the intermediate of human body carbohydate metabolism, is to be best suitable for
The sugar substitutes of the trophism of patients with diabetes mellitus.Industrialized production xylitol is mainly hydrogenated with by chemical catalysis at present
Method, this method is mature and stable, but xylose production process concentration section uses distillator to concentrate, and its shortcoming is that distillation technique is complicated multiple
Miscellaneous, still-process steam usage amount is big, and production cost is high, distillation efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of xylose desalination and concentration device, is taken off by electrodialysis and membrance separation
Salt and concentration, improve production efficiency.
For achieving the above object, this utility model is by the following technical solutions:
A kind of xylose desalination and concentration device, including the electrodialysis plant being sequentially connected with, head tank, high temperature reverse osmosis membrane group
Part, dialysate tank, the freshwater room of described electrodialysis plant has conveying pipeline with being connected between head tank, and described head tank is anti-with high temperature
Connecting before permeable membrane element and have feed pipe and reflux line, described high temperature reverse osmosis membrane assembly and dialysate tank are by dialysis
Pipeline connects.
Further, described electrodialysis plant includes being positioned at the freshwater room at middle part, the dense hydroecium of freshwater room both sides and setting
The anode chamber at standby two ends and cathode chamber, described conveying pipeline is connected with freshwater room.
Preferably, described feed pipe is provided with valve and dehvery pump.
Preferably, described reflux line is provided with heat exchanger.
After using technique scheme, this utility model has the advantages that this utility model uses electrodialysis to set
Then standby desalination uses high temperature reverse osmosis membrane to carry out separating concentration, and desalination and concentration is effective, simple in construction, workable, raw
Produce low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Primary clustering symbol description:
1: electrodialysis plant, 2: head tank, 3: high temperature reverse osmosis membrane assembly, 4: dialysate tank, 5: conveying pipeline, 6: feed pipe
Road: 7: valve, 8: dehvery pump, 9: reflux line, 10: heat exchanger, 11: dialysis pipeline.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with the accompanying drawings and tool
This utility model is described in further detail by body embodiment.
As it is shown in figure 1, the utility model discloses a kind of xylose desalination and concentration device, set including the electrodialysis being sequentially connected with
Standby 1, head tank 2, high temperature reverse osmosis membrane assembly 3, dialysate tank 4.Electrodialysis plant 1 includes the freshwater room being positioned at middle part, freshwater room
Both sides are dense hydroecium, and the two ends of equipment are respectively anode chamber and cathode chamber.Connect between the freshwater room of electrodialysis plant 1 and head tank 2
Being connected to conveying pipeline 5, head tank 2 has feed pipe 6 and reflux line 9, high temperature reverse osmosis with being connected before high temperature reverse osmosis membrane assembly 3
Permeable membrane assembly 3 is connected by dialysis pipeline 11 with dialysate tank 4.Feed pipe 6 is provided with valve 7 and dehvery pump 8.Reflux line 9
It is provided with heat exchanger 10.
Operation principle of the present utility model is: the xylose feed liquid needing desalination and concentration is squeezed into the fresh water of electrodialysis plant 1
In room, after energising, in solution, zwitterion directional migration to dense hydroecium makes the xylose solution salinity of freshwater room reduce, light after desalination
Feed liquid, in conveying pipeline 5 enters head tank 2, Open valve 7, is pumped into height by dehvery pump 8 through feed pipe 6 by the xylose of hydroecium
In temperature reverse osmosis membrane assembly 3, the moisture permeate after separation enters in dialysate tank 4 through dialysis pipeline 11, and xylose solution then passes through
Reflux line 9 is back in head tank 2, is circulated filtration.When feed temperature is too high or too low, then entered by heat exchanger 10
Row cooling or intensification.
To sum up, this utility model device first uses electrodialysis plant to carry out desalting processing, then uses high temperature reverse osmosis membrane
Xylose and moisture is made to separate the purpose reaching to concentrate.The flow of this device is big, and cost is relatively low, and desalination and concentration is effective, suitable
Preferably popularization and application.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.
