Description of drawings
Fig. 1 is the structural representation of continuous extraction apparatus of the present invention.
Mark in the above-mentioned accompanying drawing is following:
Distillation still 2, extract import 21, solute outlet 22, extractant steam mouth 23,
The specific embodiment
See Fig. 1, the continuous extraction apparatus of present embodiment comprises extraction kettle 1 and distillation still 2.
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.
