Description

Technical Field

[0001] The utility model relates to the technical field of chemical process equipment, in particular to an octabromoether solvent distillation device. Background Art

[0002] Octabromodiphenyl ether is a polybrominated compound, which is widely used as an important organic solvent in organic synthesis, pharmaceutical manufacturing and other fields. It is a colorless to pale yellow liquid with high stability and volatility at room temperature and pressure, making it one of the indispensable chemicals in many industrial and scientific research fields.

[0003] In the traditional production process of octabromoether, the distillation of solvent is an important process link, which is directly related to the quality and output of the product. The traditional distillation device performs static heating on the original solvent during use. The static heating method takes a long time to heat the solvent above the boiling point, resulting in low heating efficiency. This will prolong the time of the entire distillation process and increase energy consumption. During the static heating process, due to the limited contact area between the heating source and the solvent, it is easy to cause uneven heating of the solvent. This may cause part of the solvent to be overheated while the other part is still at a lower temperature, affecting the distillation effect and product quality.

[0004] Therefore, it is necessary to provide an octabromoether solvent distillation device to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide an octabromoether solvent distillation device to solve the problems raised in the above background technology.

[0034] In one of the embodiments, symmetrically distributed universal wheels 2 are fixedly installed on both sides of the bottom of the base plate 1 to facilitate the movement of the device and improve the convenience of people's use.

[0035] In one of the preferred embodiments, the guide plates 18 are alternately installed with tilts in different directions from top to bottom, so that the cooling water can flow more comprehensively inside the cooling box 8, thereby improving the cooling efficiency.

[0036] In one embodiment, the insulation shaft 14 is made of a nickel-based superalloy having relatively low thermal conductivity, which reduces the heat generated by the heated solvent and directly transfers it to the motor 10 through the stirring mechanism without excessively affecting the working stability of the motor 10.

[0037] In one of the preferred embodiments, an inspection door is provided below the front surface of the distillation tower 4 to facilitate inspection and maintenance of the equipment.
