Description
Technical field
This utility model relates to a kind of shell and tube continuous liquid-liquid countercurrent extraction equipment, and the liquid-liquid extraction being mainly used in the fields such as hydrometallurgy, chemical industry, medicine, food, waste water process separates, belongs to field of chemical equipment.
Background technology
Liquid-liquid extraction is to utilize the difference of material partition coefficient in the two-phase solvent of immiscible (or slightly soluble) to realize the unit operation that mixture separates.Needing two kinds of density differences in extracting operation, the solution of immiscible (or slightly soluble) separates after being sufficiently mixed again, to reach to separate or purify the purpose of target compound.The most conventional extraction equipment extraction efficiency is low, it is difficult to realize continuous extraction operation, it is therefore necessary to provide a kind of easy to operate, it is possible to realize the countercurrent extraction equipment of continuous extraction.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction to overcome above deficiency, with extraction efficiency intensifier, the shell and tube continuous liquid-liquid countercurrent extraction equipment that is capable of continuous countercurrent extraction.This utility model simple in construction, easy and simple to handle, it is adaptable to industrialized production.
A kind of shell and tube continuous liquid-liquid countercurrent extraction equipment, including extraction column, it is characterized in that the light phase solvent feed mouth being arranged over being connected of described extraction column with light phase solvent tubulation, lower section is provided with the heavy phase solvent feed mouth being connected with heavy phase solvent tubulation, top is provided with the light phase solvent discharging opening being connected with light phase solvent collecting region, and bottom is provided with the heavy phase solvent discharging opening being connected with heavy phase solvent collecting region；Described light phase solvent tubulation and heavy phase solvent tubulation are the most longitudinally positioned at described extraction column, and its port not being connected with charging aperture is respectively close to bottom and the top of described extraction column.
Described light phase solvent tubulation and heavy phase solvent tubulation are several and are spaced in described extraction column.
Described extraction column can be high according to the different post footpath of separation requirement different designs and post, can add filler, arranges liquid re-distributor and increase its extraction efficiency in extraction column.
Described light phase solvent feed mouth, in upper end, arrives bottom extraction column by light phase solvent tubulation, the most naturally rises, the light phase light phase solvent discharging opening discharge from upper end；Heavy phase solvent feed mouth, in lower end, arrives extraction column top by heavy phase solvent tubulation, the most naturally declines, and heavy phase is discharged from bottom heavy phase solvent discharging opening；By this design, thus light in realizing extraction column, weight two phase countercurrent flow extraction process and add strong solvent in mixing radially, improve extraction efficiency.
In described extraction column, spaced multiple light, heavy phase solvent tubulations improve two-phase solvent in distribution radially and mixing, it is achieved light, weight is biphase carries out counter-current extraction around tubulation, it is to avoid the short circuit of solvent and mix uneven problem, improve extraction efficiency.
This utility model realizes counter-current extraction by tubulation in extraction column, makes all can keep between light, the weight two-phase solvent of same level position in whole extraction column certain target compound concentration difference.
In equipment described in the utility model, target compound can dissolve with light phase, uses heavy phase solvent extraction；Heavy phase can also be dissolved in, use light phase solvent extraction.
This utility model compared with prior art has the advantage that simple and reasonable, easy and simple to handle, it is possible to ensures that light, weight two-phase solvent is fully contacted in extraction column, improves mass transfer separation efficiency, it is easy to obtain highly purified target compound product.

Detailed description of the invention
As shown in Figure 1, a kind of shell and tube continuous liquid-liquid countercurrent extraction equipment, including extraction column 9, the light phase solvent feed mouth 1 being arranged over being connected with light phase solvent tubulation 6 of extraction column 9, lower section is provided with the heavy phase solvent feed mouth 2 being connected with heavy phase solvent tubulation 5, top is provided with the light phase solvent discharging opening 3 being connected with light phase solvent collecting region 7, and bottom is provided with the heavy phase solvent discharging opening 4 being connected with heavy phase solvent collecting region 8；Light phase solvent tubulation 6 and heavy phase solvent tubulation 5 are all longitudinally positioned at extraction column 9, and its port not being connected with charging aperture is respectively close to bottom and the top of extraction column 9.
Light phase solvent tubulation 6 and heavy phase solvent tubulation 5 are several and are spaced in extraction column 9.
During use, light phase solvent is after light phase solvent feed mouth 1 pumps into, being entered in extraction column 9 from extraction column bottom by light phase solvent tubulation 6, naturally rise and contact with the heavy phase solvent flowed down from top and start to extract, after light phase solvent collecting region, top 7 is collected, from top, light phase solvent discharging opening 3 flows out；And heavy phase solvent is after heavy phase solvent feed mouth 2 pumps into, enter in extraction column 9 by heavy phase solvent tubulation 5 from extraction column top, naturally the light phase solvent declined and rise with bottom contacts and extracts, flow out from bottom heavy phase solvent discharging opening 4 after heavy phase solvent collecting region, bottom 8 is collected, thus complete whole counter-current extraction process.During extracting operation, target compound can be dissolved in gently, in a phase solvent in heavy phase, use another phase solvent to extract, pump into biphase liquid by lasting and collect the two-phase solvent after extracting on extraction column top and bottom respectively, it is possible to achieve continuous countercurrent extracting operation.
