Abstract
The utility model discloses an amino glycerine dehydration removes salt system, including stills, condenser and vacuum pump, still including reboiler and vapour and liquid separator, the liquid outlet that stills's lateral wall lower part was seted up is continuous with the inlet of circulating pump, the import that the liquid outlet of circulating pump was equipped with bottom the reboiler links to each other, export that the reboiler top was equipped with links to each other with the import that vapour and liquid separator lateral wall upper portion was equipped with, export that vapour and liquid separator bottom was equipped with links to each other with the inlet that the stills top was seted up, export that the vapour and liquid separator top was equipped with links to each other with the import at condenser top, the export of condenser bottom links to each other with the import of receiving the jar, it links to each other with the vacuum pump to receive the jar. Simple structure can improve the dehydration rate greatly, thereby the amino glycerine after the separation obtains the dehydration desalination is accomplished with solid -state salt to the amino glycerine in the stills under the separation of centrifugal separator, and distilling efficiency improves greatly.
Description
Technical field
The utility model relates to the preparation field of amino-glycerol, is specifically related to a kind of amino-glycerol dehydration desalting system.
Background technology
Amino-glycerol (C
3h
9nO
2) be not only and produce X-CT non-ionic contrast agent ioversol, Schering AG), the irreplaceable raw material of iopamidol, also can be used as pesticide intermediate, emulsifying agent, organic synthesis intermediate, there is purposes widely.
The preparation of current amino-glycerol mainly contains propylene oxide method, glycerin chlorohydrin method, Racemic glycidol method, Glycerose method, Ammonia Process etc.The amino-glycerol crude product of above-mentioned preparation technology's gained all needs through the operation of dehydration desalination, because the boiling point of amino-glycerol is higher than water, existing dehydration desalination is all by distillation method, but there is a large amount of NaCl in crude product, evaporation NaCl concentration along with moisture uprises gradually to saturated, boiling point also raises to become gradually and not easily evaporates, and causes dehydration not exclusively, is unfavorable for follow-up purification operations.
Utility model content
The utility model overcomes existing defect provides a kind of amino-glycerol dehydration desalting system, and structure is simple, accelerates amino-glycerol and reclaims speed, enhance productivity.
The utility model is achieved through the following technical solutions:
Amino-glycerol dehydration desalting system, comprise still kettle, condenser and vacuum pump, also include reboiler and gas-liquid separator, the liquid outlet that the lower sidewall of described still kettle is offered is connected with the fluid inlet of recycle pump, the liquid outlet of described recycle pump is connected with the import be provided with bottom described reboiler, the import that the outlet that described reboiler top is provided with is provided with described gas-liquid separator side wall upper part is connected, the fluid inlet that the outlet be provided with bottom described gas-liquid separator is offered with described still kettle top is connected, the outlet that described gas-liquid separator top is provided with is connected with the import of described condenser overhead, outlet bottom described condenser is connected with the import of receiving tank, described receiving tank is connected with vacuum pump.
The further improvement project of the utility model is that described gas-liquid separator is positioned at the top of described still kettle, reboiler.
The further improvement project of the utility model is that described condenser is positioned at the top of described receiving tank.
The further improvement project of the utility model is that the outlet be provided with bottom described still kettle is connected with whizzer, and the top of still kettle is also provided with the opening for feed entered for material.
Compared to the prior art the utility model has the following advantages:
The utility model structure is simple, material under the effect of recycle pump in still kettle, reboiler, gas-liquid separator cycle operation, the moisture evaporation that material is vaporized after the intensification of reboiler under the effect of gas-liquid separator is reclaimed by follow-up receiving tank, the amino-glycerol of liquid phase is then got back in still kettle, circulation like this, can continue to be distilled to dewater completely, greatly improve dehydration rate, amino-glycerol in still kettle and solid-state salt complete the amino-glycerol be separated thus acquisition is dewatered after desalination under the separation of whizzer, and the efficiency of distillation improves greatly.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
