Description
Technical field
The utility model relates to fire retardant production technical fields, and in particular to a kind of hexabromo ring 12 with dehydration device
Alkane production system.
Background technique
Hexabromocyclododecane (abbreviation HBCD) is a kind of high-quality bromide fire retardant of addition type, the low, flame retardant effect with dosage
Well, advantage small, good to heat and ultraviolet light stability is influenced on material physical property, is mainly used as polystyrene foam, Gao Chong
The materials such as polystyrene, binder and coating it is fire-retardant.Currently, most hexabromocyclododecane (HBCD) is by 1,5,9- ring ten
Two carbon triolefins (CDT) and bromine occur bromination addition reaction in the in the mixed solvent of isobutanol and chloroform and are made.Hexabromo ring 12
The production of alkane (HBCD) mainly carries out in reaction kettle, reacts and is centrifuged after hexabromocyclododecane solution is made with centrifuge,
Hexabromocyclododecane crude product enters washing kettle and is washed after centrifugation, and centrifugation obtains hexabromocyclododecane fine work after washing,
It finally entering bipyramid drying machine drying and obtains finished product, mother liquor after centrifugation enters distillation still with solvent and is distilled to recover, and
At present for the recycling of solvent, it is impure more that there are solvents, the low problem of recovery efficiency.
Utility model content
In view of the above technical problems, the utility model provides a kind of hexabromocyclododecane production system with dehydration device
System is carried out dehydrating mixed solvent by increasing dehydrating kettle, improves dehydration rate, reduce the generation of by-product, improves
Solvent recovery efficiency.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of hexabromocyclododecane production system with dehydration device, bromination reaction kettle and crude product including sequential communication
Centrifuge, the crude product centrifuge are equipped with crude product outlet and solvent outlet, and the solvent outlet sequential communication has distillation still, condensation
Device, dehydrating kettle and solvent tank.
Preferably, the condensing unit includes the enameling glass chip condenser and plate-type condenser being serially connected.
Preferably, agitating device is equipped in the dehydrating kettle.
Preferably, temperature sensor is equipped in the dehydrating kettle.
Preferably, the outer wall of the dehydrating kettle is equipped with collet, after thermal medium enters collet, transfers thermal energy in dehydrating kettle
Portion realizes the heating to material, improves dehydrating effect.
Preferably, multiple flow-stopping plates are along the circumferential direction equipped on the inner wall of the dehydrating kettle.
The beneficial effects of the utility model are shown: adding dehydrating kettle, dehydrating kettle water-bearing media is added appropriate water-soluble
After demulsifier under the conditions of certain temperature, make its water-oil separating by the regular hour, improve dehydration efficiency, be dehydrated it is time saving,
It is laborsaving, it is easy to use；By using the condensing unit that enameling glass chip condenser and plate-type condenser combine, heat-transfer surface is increased
Product, improves work efficiency, condensation effect is good；In dehydrating kettle internal flow whipping process, fluid and flow-stopping plate generate collision,
To enhance mixing effect, dehydrating effect is improved.
