Abstract
The utility model discloses a solvent recovery and water removal device for sucralose production. The solvent recovery and water removal device for the sucralose production includes an evaporator, a condenser and a water separating tank, wherein the evaporator is communicated with the inlet of the condenser through a pipeline, the water separating tank is communicated with the outlet of the condenser through a pipeline, the water separating tank is communicated with the evaporator through a backflow pipe, and a backflow valve is arranged on the backflow pipe. The solvent recovery and water removal device for the sucralose production can continuously and automatically subject trichloroethane to water removal, greatly improves water removal efficiency, and is simple in structure and convenient to operate.
Description
Technical field
The utility model relate generally to trichloroethanes and water in the sucrose trichloride production process mixture separate water removal device.
Background technology
Sucralose trichloroethanes solvent recovery in process of production all is to carry out branch water by the mode of static layering at present, has not thorough, moisture the exceeding standard that dewater, and consuming time longer, can not realize problems such as continuous dewatering esterase, influences production efficiency greatly.
Summary of the invention
Goal of the invention: at problem and the defective of above-mentioned existence, the utility model provides a kind of solvent recovery de-watering apparatus for Sucralose production, can realize the trichloroethanes solvent is dewatered continuously automatically by this device, and water content can be controlled at 100～500ppm, has improved the efficient that dewaters greatly.
Technical scheme: to achieve the above object of the invention, the utility model is by the following technical solutions: a kind of solvent recovery de-watering apparatus of producing for Sucralose, comprise evaporating kettle, condenser and water distributing can, described evaporating kettle is communicated with condenser inlet by pipeline, described water distributing can is communicated with condensator outlet by pipeline, described water distributing can is communicated with by reflux line with evaporating kettle, and this reflux line is provided with return valve.
Further improve, described water distributing can is provided with visor.
Technique scheme is further improved, also be provided with return duct on the described water distributing can, this return duct one end stretches in the water distributing can, and upper end edge is concordant with the visor center, and the part of exposing of this return duct is provided with draining valve simultaneously.
Beneficial effect: compared with prior art, the utlity model has following advantage: this device can be realized trichloroethanes is dewatered continuously automatically, has improved the efficient that dewaters greatly; And it is simple in structure, easy to operate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, evaporating kettle 1, condenser 2, water distributing can 3, pipeline 4, return valve 5, visor 6, draining valve 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of solvent recovery de-watering apparatus for Sucralose production, it comprises evaporating kettle 1, condenser 2 and water distributing can 3, the top of evaporating kettle 1 is connected with condenser 2 suction flanges by the DN125 pipeline, and the outlet of condenser 2 utilizes the DN50 pipeline to be connected with the top flange of water distributing can 3 equally; Described water distributing can 3 is communicated with formation with evaporating kettle 1 by reflux line and refluxes, and this reflux line is provided with return valve 5.In addition, be provided with visor 6 and return duct at water distributing can 3, this return duct one end stretches in the water distributing can 3, and front end is bent upwards, and the control upper end edge is concordant with visor 6 centers, and return duct exposes the part of water distributing can 3 and is provided with draining valve 7.Equal like this return duct has been done individual water seal, can guarantee that again the stratification line of water and solvent can be controlled all the time in visor 6 scopes.
For example: reclaiming trichloroethanes solvent processing procedure:
1, checks whether all valve situations of distillation still state of living in is normal;
2, distillation still charging, volume is at 2.48m
3About;
3, open jacket steam and heat up, control chuck pressure 2 ~ 3Mpa opens 7 of water distributing can 3 charging valves and emptying draining valves; Equitemperature rises to 95 degree when above, because after reaching trichloroethanes and water higher boiling, produce pressure, and formation steam, steam is gone into water distributing can 3 by condenser 2 condensations, notice that water distributing can 3 liquid levels begin to rise, at this moment will open draining valve 7, it is normal to control branch water canister liquid level by draining valve 7, in time water is discharged by 7 of emptying draining valves;
4, owing to the density of trichloroethanes density greater than water, the water-fast characteristic of trichloroethanes, below the very fast layering of trichloroethanes sinks to, form tangible layering with water, this moment, water distributing can 3 following trichloroethanes reached moisture maximum saturation, trichloroethanes by 3 li of water distributing cans constantly is back in the still, the water of trichloroethanes constantly has trichloroethanes to take out of in the still, constantly remove by water distributing can 3, because the water of trichloroethanes constantly reduces in the still, trichloroethanes and water ratio change, and their higher boiling also rises thereupon, so temperature in the kettle can progressively rise;
5, after temperature in the kettle reaches 116 ℃ of degree, the moisture of material in the still that dewaters surveyed in sampling, can accomplish substantially moisture below 400ppm, sampling detect qualified after, can stop water removal operation, turn off all valves, wait for and change the material operation.

| 3002 | 145 |
| 3561 | 100 |
| 2569 | 123 |
| 2645 | 214 |
With this equipment operation cycle be 3 hours stills, therefore can provide extensive Batch Process, can significantly pass through production efficiency, adopt stable that this equipment can ensure the quality of products, it is the same with the maintenance of outsourcing quality to reclaim quality.
