Sterling amine technique is unstable, and cost of manufacture is high, so supplying without sterling amine.Prior art can only be with aqueous solution as molten
Agent, without solvent selectivity, in technique can only hydrous water produced as solvent, there are many anhydrous responses only to rest on small
The examination stage can not amplify production.Many anhydrous response process routes have been got through, and being only stuck in raw material level can not be pushed away
Into；In previous production, when needing anhydrous amine raw material, we can heat aqueous solution and evaporate by amine, remove by aeration tower
Water is reacted being led directly in reaction system by pipeline, and the sterling boiling point of common amine is generally taken the photograph at 16 degrees Celsius to -10
Between family name's degree, sterling raw material under aeration tower often condenses in venting process in turn results in the loss of sterling, also brings waste liquid
The increase of amount.Reaction system, no standard measure are passed directly by the amine of gas washing；Being passed through amine can only be excessive, former by sampling monitoring
Material reaction progress is to determine whether stop being passed through for amine；Due to the big excess of amine, post-processing difficulty is caused to increase；To washing, extraction
The subsequent processing taken increases many workloads.
Summary of the invention
The utility model makes up the shortcomings of the prior art aiming at the above problem, provides a kind of efficient, low-risk
Sterling amine acquisition system；The utility model is suitable for various methylamines, the amine of ethylamine solution, and water separation is suitble to be put in big
Production.
To achieve the above object, the utility model adopts the following technical solution.
A kind of sterling amine extraction system of the utility model, it is characterised in that: including heating reaction kettle, the first cooler, add
Hot caustic bath, the second cooler, sterling low-temperature storage tank, diaphragm pump, tail gas recycle bucket；In the exit of heating reaction kettle upper end side

Alkali piece；The outlet of hot caustic bath is added to connect by pipeline with the second cooler, the outlet of the second cooler connects sterling by pipeline
The outlet of low-temperature storage tank, sterling low-temperature storage tank is connected by pipeline with diaphragm pump, and the outlet of diaphragm pump connects tail gas by pipeline
Recycling bin.
As a kind of preferred embodiment of the utility model, first cooler uses serpentine coil formula condenser.
As another preferred embodiment of the utility model, second cooler uses plate type condenser；It is described
Plate type condenser be a kind of high efficient cryogenic cooler, compared to its active cooling surface of common cooler product become larger, cooling effect
It is extremely excellent.
As another preferred embodiment of the utility model, liquidometer is installed on the sterling low-temperature storage tank.
As another preferred embodiment of the utility model, the diaphragm pump is technical grade diaphragm pump.
The utility model beneficial effect.
1, a kind of sterling amine extraction system provided by the utility model, has been efficiently obtained amine sterling, reaction dissolvent
Anhydrous sterling can be directly used, the amine aqueous solution of respective concentration, organic solvent selectivity can also be obtained by dilution means
Extensively；Meanwhile the amine aqueous solution of designated solvent can be obtained further through tail gas recycle.The utility model has efficiently controlled the production of the three wastes
It is raw, it improves efficiency, reduces risk, reduce operation difficulty, be further reduced control point.
2, the second cooler described in the utility model uses plate type condenser, and compared to common cooler, it is effectively cooling
Area becomes larger, cooling effect is extremely excellent, and the diaphragm pump job specification of the diaphragm pump is simple, the ginseng without this medium of water oil
With；By using the sterling amine extraction system of the utility model, the cost of manufacture of sterling amine is reduced, and compensates for the sky in industry
It is white.
Detailed description of the invention
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with the drawings and the specific embodiments, the present invention will be further described in detail.It should be appreciated that tool described herein
Body embodiment is only used to explain the utility model, is not used to limit the utility model.
Fig. 1 is a kind of overall structure diagram of sterling amine extraction system of the utility model.
Marked in the figure: 1 is heating reaction kettle, 2 be the first cooler, and 3 is add hot caustic bath, and 4 be the second cooler, and 5 be pure
Product low-temperature storage tank, 6 be diaphragm pump, and 7 be tail gas recycle bucket, and 8 be pipeline, and 9 be liquidometer.
Specific embodiment
In conjunction with shown in attached drawing, a kind of sterling amine extraction system of the utility model, it is characterised in that: including heating reaction kettle 1,
First cooler 2 plus hot caustic bath 3, the second cooler 4, sterling low-temperature storage tank 5, diaphragm pump 6, tail gas recycle bucket 7；It is anti-in heating
Answer the exit of 1 upper end side of kettle that the first cooler 2 is installed, the outlet of the first cooler 2 adds hot caustic bath 3 by the connection of pipeline 8,
Solid base piece is equipped in described plus hot caustic bath 3；The outlet of hot caustic bath 3 is added to connect by pipeline 8 with the second cooler 4, second
