Description
Technical field
The invention belongs to field of chemical engineering, and in particular to a kind of small-sized Liquid-liquid equilibrium kettle.
Background technology
Liquid-liquid equilibrium kettle is a kind of less Liquid-liquid equilibrium kettle of capacity, for determining Liquid-liquid equilibrium data.Changing
Learn in industry, extraction, the technique of distillation process and equipment design are required for accurate Liquid-liquid equilibrium data, the offer of this data
Exact Design is extracted or the process operation parameter and equipment size of rectifying are most important, is widely used in extracting and dephenolizing, purification
Etc. various fields.Although many data can be estimated using simulation softward, obtaining accurate Liquid-liquid equilibrium data can return
Return the key parameter for obtaining thermodynamical equilibrium equation so that process simulation is more accurate.With the exploitation of new technology, new extractant is not
Disconnected discovery and the continuous extension of abstraction technique application field, also non-someone of many Liquid-liquid equilibrium data determine, and are required to pass through
The mode of measuring is to obtain design parameter to meet the demand of engineering calculation.
Either scientific research institutions, research institution's research and development or student experimenting operation are single to extraction to strengthen for Liquid-liquid equilibrium kettle
The many-side such as understanding of member is all in daily use.Liquid-liquid equilibrium data are determined, phasor, analysis temperature, concentration on extraction is drawn out
Influence of energy etc., is required to lot of experimental data.Experimentation needs to control the minor variations of concentration in temperature, liquid phase all to lead
Biphase equilibrium is caused to produce movement.Some equilibrium stills can cause lower floor's sample sampling contaminated through upper strata sample when may remove layer sample；
Some equilibrium stills clamp lower floor's sample using interface export closed with flexible pipe again, have one section of dead angle in outlet section, stirring is not
Uniformly, and the flexible pipe easy leakage of inserting needle sampling repeatedly.Some equilibrium stills can not set stirring and layering time of repose, it is impossible to and
When sample so that particularly under conditions of the experiment of high temperature due to sample place evaporate too long influence liquid-liquid equilibrium result
Etc..
The content of the invention
For solve prior art shortcoming and defect in place of, it is an object of the invention to provide one kind control when, temperature control stirring
Rationally, accurately and conveniently small-sized Liquid-liquid equilibrium kettle is sampled.

Higher than more than stirring magneton and avoiding being stirred magneton collision.During sampling extraction phase and extraction can be directed respectively into using plastics small hose
Yu Xiang so that sampling is not interfere with each other.
The glass port grinding bottle is connected with thermometer, continuous observation temperature beyond the Great Wall, and accurately obtains temperature information in sampling.
The outer layer of the vial of the jacketed is provided with circulation water inlet and circulating water outlet, circulation of the recirculated water from lower end
Water inlet enters, from the circulating water outlet outflow to upper end.Made in mixing using recirculated water temperature control and using magneton is stirred
It must stir, stirring stops the agitation of stirring magneton and temperature control stratification after terminating.
The inner bag distance from bottom raffinate phase sample tap bottom distance of the vial of the jacketed need to be more than cylindricality and stir magnetic
1.5 times of sub- diameter, to avoid causing impact damage to raffinate phase sample tap bottom during stirring magneton stirring.
The extraction phase sample tap bottom both can be more than two liquid phases, can also be in the extraction phase of upper strata.Can during sampling
Plastics small hose is stretched into upper strata extraction phase and obtains the uniform fluid sample of typical hybrid.
The raffinate phase sample tap bottom is necessarily in lower floor's raffinate phase, but higher than stirring magneton.It will can be moulded during sampling
Material small hose stretches into lower floor's raffinate phase and obtains the uniform fluid sample of typical hybrid.
A kind of described small-sized Liquid-liquid equilibrium kettle, although temperature can produce fluctuation in Liquid-liquid equilibrium continuous mode,
But finally it is defined by sampling chronothermometer reading.
Compared with prior art, the present invention has advantages below and beneficial effect：
(1) can be closed by two sample taps with a conduit, it is to avoid two-phase is lost.
(2) can either it be stirred or stratification with temperature control all the time.
