Abstract
The utility model discloses a solvent condensing device for producing hexabromocyclododecane. The solvent condensing device comprises a distilling still, a solvent gas outlet is arranged at the top of the distilling still and communicated with a condensing device, the condensing device comprises a glass lining sheet type condenser and a plate type condenser which are serially connected with each other, and a solvent liquid outlet of the plate type condenser is communicated with a solvent storage tank. The solvent condensing device for producing the hexabromocyclododecane is good in condensing effect, high in work efficiency and capable of saving circulating water and chilled water.
Description
Technical field
The utility model relates to fire retardant production equipment technical field, relates in particular to be used for the solvent condenses device that HBCD is produced.
Background technology
HBCD (HBCD), molecular weight 642, white crystals; Multiple isomers is arranged, and LMP type fusing point is 167-168 ℃, and high melting temperature type is 195-196 ℃.HBCD (HBCD) is the alicyclic additive flame retardant of a kind of high bromine content (can reach 74.7%); It has that consumption is low, good flame retardation effect, little to the material physical property influence, to heat and the good advantage of ultraviolet light stability; Be mainly used in EPS (expanded polystyrene (EPS); With reference to consumption 2%), in polypropylene (with reference to consumption 2%HBCD, 1% antimony oxide) and other styrene resin.In addition, it is applicable to knitted fabric, butadiene-styrene rubber, adhesive and coating, and unsaturated polyester resin carries out flame treatment.
At present, most HBCD (HBCD) is by 1,5, and 9-cyclodoecatriene (CDT) and bromine the bromination addition reaction take place in several types of mixed solvents such as isobutanol and chloroform make.The production of HBCD (HBCD) is mainly carried out in agitated reactor, and reaction makes to be carried out behind the HBCD solution centrifugally with centrifuge, get into distillation still after centrifugal and wash, and gets into the bipyramid drying machine drying after the washing and obtains finished product.Solvent in the HBCD solution is through the centrifugal distillation still that gets into afterwards of centrifuge; Distillation still is communicated with enameling glass chip condenser and solvent storage tank; Be condensed at enameling glass chip condenser internal solvent gas and cooling water generation heat exchange, the sheet spacing of enameling glass chip condenser is little and even; Medium spreads times without number, and it is slower to lower the temperature, and condensation effect is not good, has influenced the organic efficiency of solvent, is unfavorable for the raising of production efficiency yet.
The utility model content
The utility model technical problem to be solved is: to the deficiency that prior art exists, the solvent condenses device that is used for HBCD production of the good and high efficiency of a kind of condensation effect is provided.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Be used for the solvent condenses device that HBCD is produced; Comprise distillation still; Said distillation still top is provided with the solvent gas outlet, and said solvent gas outlet is communicated with condensing unit, and it is characterized in that: said condensing unit comprises the enameling glass chip condenser and the plate-type condenser of mutual series connection.
As a kind of scheme, the outlet of the solvent liquid of said plate-type condenser is communicated with the solvent storage tank.
As a kind of scheme, said distillation still bottom is surrounded with chuck.
Owing to adopted technique scheme, the beneficial effect of the utility model is:
1, the distillation still solvent gas outlet of the utility model is communicated with enameling glass chip condenser and plate-type condenser in proper order; Solvent gas at first gets into enameling glass chip condenser;, enameling glass chip condenser inside gets into plate-type condenser after carrying out condensation again; Adopt such structure, increased heat exchange area, improved operating efficiency.
2, solvent gas is condensed into liquid in the inner major part of enameling glass chip condenser, and the solvent after being condensed gets into plate-type condenser and continues to be condensed into liquid.Adopt the condenser of two-part, can control condensation water and freezing water easily, energy savings, and condensation effect is good.
