By using the device provided by the utility model, the whole extracting process can be guaranteed to be carried out continuously, and the manual operation is not needed. Furthermore, due to the design, the height of the whole extracting device can be decreased, and the requirements on a work site are not high.
Description
Technical field
The utility model relates to a kind of chemical engineering unit operation equipment, is specifically related to a kind of continuous extraction apparatus.
Background technology
At present a lot of extraction equipments all need manually-operated, and can't carry out continuous extraction, greatly reduce extraction efficiency like this.The height of whole extraction equipment is very high in addition, has relatively high expectations for the production place.
The utility model content
The purpose of the utility model is to address the above problem, and provides a kind of and need not manually-operated, to the less demanding continuous extraction apparatus in production place.
The technical scheme that realizes the utility model purpose is: a kind of continuous extraction apparatus comprises extraction kettle and distillation still; Said extraction kettle is provided with charging aperture, extract outlet and extractant liquid return hole; Said distillation still is provided with extract import, solute outlet and extractant and steams mouth; The extract outlet of said extraction kettle is connected with the extract import of said distillation still through liquid extraction pipe; The extractant of said distillation still steams mouth and is connected with the extractant liquid return hole of said extraction kettle through the extractant pipe; The ratio of the distance H 1 between the distance H 2 between the liquid level in outlet of said extract and the extraction kettle and outlet of said extract and the said extract import equals the density ratio of high density extractant and the former solvent of low-density.
The extractant liquid return hole of said extraction kettle is provided with cooling sprayer.
The good effect that the utlity model has: the device of the utility model makes the ratio of the distance between the extract import of extract outlet and distillation still of extract outlet and distance between the liquid level in the extraction kettle and extraction kettle of extraction kettle equal the density ratio of the lower former solvent of the higher extractant of density and density; Make that like this pressure of extraction kettle and distillation still is identical; Thereby guarantee that whole extraction process can carry out continuously, and need not manually-operated.And this design can be so that the height of whole extraction equipment be minimized, and is less demanding to the production place.
Description of drawings
Fig. 1 is the structural representation of the continuous extraction apparatus of the utility model.
Mark in the above-mentioned accompanying drawing is following:
Extraction kettle 1, charging aperture 11, extract outlet 12, extractant liquid return hole 13,
Distillation still 2, extract import 21, solute outlet 22, extractant steam mouth 23,
Liquid extraction pipe 3, extractant pipe 4, cooling sprayer 5.
The specific embodiment
See Fig. 1, the continuous extraction apparatus of present embodiment comprises extraction kettle 1 and distillation still 2.
Extraction kettle 1 is provided with charging aperture 11, extract outlet 12 and extractant liquid return hole 13.Distillation still 2 is provided with extract import 21, solute outlet 22 and extractant and steams mouth 23.
The extract outlet 12 of extraction kettle 1 is connected with the extract import 21 of distillation still 2 through liquid extraction pipe 3.The extractant of distillation still 2 steams mouth 23 and is connected with the extractant liquid return hole 13 of extraction kettle 1 through extractant pipe 4.
The ratio of the distance H 1 between the extract outlet 12 of distance H 2 between the liquid level in outlet 12 of the extract of extraction kettle 1 and the extraction kettle 1 and extraction kettle 1 and the extract import 21 of distillation still 2 equals the density ratio of high density extractant and the former solvent of low-density.
The extractant liquid return hole 13 of extraction kettle 1 is provided with cooling sprayer 5.
Adopt method that the continuous extraction apparatus of present embodiment carries out continuous extraction (is example with the bromine in the chloroform extraction water) as follows:
1. chloroform (extractant) and brominated water (feed liquid) are together joined the extraction kettle 1 from charging aperture 11; Make bromine and layering in the chloroform extraction water, the ratio of the distance H 1 between distance H 2 between the liquid level of chloroform that is added and brominated water and the extract outlet 12 and extract import 21 and the extraction kettle outlet 12 equals the density ratio of chloroform and water.
2. the brominated chloroform (extract) of lower floor is discharged from extract outlet 12, and feed the distillation still 2 from extract import 21 through liquid extraction pipe 3.Keeping simultaneously joins brominated water the extraction kettle 1 from charging aperture 11, and remains the density ratio that ratio that distance H 2 and extract import 21 and extraction kettle between liquid level in the extraction kettle 1 (water and a small amount of undischarged brominated chloroform by being positioned at the upper strata after initiate brominated water, the extraction are formed) and the extract outlet 12 export the distance H 1 between 12 equals chloroform and water.
3. the brominated chloroform in the distillation still 2 is distilled; The chloroform that distills out is steamed mouthful 23 discharges from extractant; And feed cooling sprayers 5 from extractant liquid return hole 13 through extractant pipe 4, after supercooling, get back in the extraction kettle 1 recycling through spray equipment.This process remains the density ratio that ratio that distance H 2 and extract import 21 and extraction kettle between liquid level in the extraction kettle 1 (chloroform by being positioned at water, a small amount of undischarged brominated chloroform on upper strata after initiate brominated water, the extraction and getting back to extraction kettle 1 is formed) and the extract outlet 12 export the distance H 1 between 12 equals chloroform and water.The bromine that obtains after the distillation is then discharged from solute outlet 22.
