Description
Technical field
The utility model relates to the transformations to extraction device, belong to chemical field, specifically design a kind of extraction device heat exchange
Device improves structure.
Background technique
The heat exchanger of extraction device is usually used in the heat exchange to lean solvent and water stripping, and heat exchanger original design type is to raise the nose above water to breathe
Formula, enclosure interior tube bank are in gas liquid film position, and tube side dielectric solvent is sulfolane, shell side medium high-temperature water.In shell
Superheated vapor turns to steam and send to solvent regeneration tower, the heat exchanger tube of gas liquid film position, and high-temperature water is vaporized in sparging process, led
Cause heat exchange tube vibration big, bubble-break generates stress corrosion.Because of process flow reason, chloride ion is in lean solvent/stripping in system
Enrichment, can not be discharged in water- to-water heat exchanger shell, and aggravation corrosion causes heat exchanger that tube bank leakage occurs, restrains actual life
It only about 12 months, causes the unplanned property of device to stop work, influences device and be steadily safely operated.
Summary of the invention
According to defect of the existing technology, the purpose of this utility model is by lean solvent/stripping water- to-water heat exchanger knot
Configuration formula and process flow are transformed, and effectively extend heat exchanger tube service life.
In order to achieve the above objectives, the technology employed by the present utility model is a kind of extraction device heat exchanger improves knot
Structure, the heat exchanger are autoclave heat exchanger, including shell, tube bank and bobbin carriage, and bobbin carriage is connected to the side of shell, and tube bank setting exists
In shell, the end for restraining one end is arranged in bobbin carriage, and heat exchanger tube all impregnates in the liquid phase, and exchanger base is provided with
Several condensate drain points.
Further, the condensate drain point is three, and three condensate drain points connect solvent regeneration tower by pipeline.
Further, the shell is connected by stud with nut with bobbin carriage, and junction is provided with gasket.
Further, the inner walls are provided with slideway.
Further, lean solvent import is set at the top of the bobbin carriage, and bobbin carriage bottom is arranged lean solvent and exports.
Further, the exchanger base is provided with fixed saddle and movable saddle.
Further, the heat exchanger shell is provided with liquid level meter mouth far from the side of bobbin carriage, and liquid level meter mouth is two groups, point
It She Zhi not be in upper and lower two parts.
Further, heat exchange of the heat exchanger for extraction device lean solvent or water stripping.
The utility model has the following beneficial effects: lean solvent/water stripping heat exchanger pattern transform autoclave as, improves and control shell
Body inside liquid level guarantees that tube bank is all impregnated in the liquid phase, and reduction tube bundle vibration can effectively reduce corrosion, and extending tube bank makes
Use the service life.

Hot device tube bank is all impregnated in the liquid phase, and exchanger base is provided with several condensate drain points 4.
Further, the condensate drain point is three, and three condensate drain points 4 connect solvent regeneration tower 10 by pipeline.
Further, the shell 1 is connected by stud with nut with bobbin carriage 3, and junction is provided with gasket.
Further, the inner walls are provided with slideway 5.
Further, lean solvent import 7 is set at the top of the bobbin carriage, and bobbin carriage bottom is arranged lean solvent and exports 8.It is set on bobbin carriage
It is equipped with lifting lug, lifting lug is only applicable to swing pipe case weight.
Further, the exchanger base is provided with fixed saddle and movable saddle.
Further, the heat exchanger shell is provided with liquid level meter mouth 9 and level control mouth, liquid level far from the side of bobbin carriage
It counts mouth and level control mouth is two groups, heat exchanger shell is respectively arranged with one group of liquid level meter mouth and level control in upper and lower two parts
Mouthful.Liquid level meter mouth and level control mouth stretch out shell, and are stabilized on shell by tilt stand.
Lean solvent/water stripping heat exchanger pattern transform autoclave as, improves and control enclosure interior liquid level, guarantees tube bank all
It impregnates in the liquid phase, reduces tube bundle vibration, effectively reduce corrosion.Housing bottom newly increases three condensate drain points, periodically by high-temperature water
It arranges to solvent regeneration tower, by solvent regeneration tower periodical blowdown, solvent system is discharged in a part of chloride ion.After transformation, tube bank
Service life greatly prolongs, and service life improves 3-4 times.
Listed above is only the most preferred embodiment of the utility model.Obviously, the utility model is not limited to above embodiments,
It is acceptable that there are many deformations.Those skilled in the art directly can export or associate from content disclosed by the utility model
