Description
Technical Field
The utility model relates to the technical field of bromine extraction experimental equipment, in particular to a bromine extraction device for experiment distillation.
Background
The natural sources of bromine are found primarily in seawater, underground concentrated brine, and salt lake water. Bromine and bromide derived from the bromine are widely applied to industries such as pesticides, medicines, petroleum, dyes and the like, and are also one of basic chemical raw materials for producing flame retardants, fire extinguishing agents and photosensitive materials. The bromine production method comprises the following steps: a steam distillation method, an air blowing method, a continuous double-process vacuum bromine extraction method, a resin method, a semi-permeable membrane method, a solvent extraction method and the like. Among them, the steam distillation method and the air blowing method are most commonly used.
The air blowing method is a bromine production method mainly used in China at present, and the principle is as follows: bromine ions in brine are changed into bromine after being oxidized by chlorine, then the bromine is blown out of the brine by air, the blown bromine is absorbed by an acidic or alkaline absorbent, then chlorine is added into an absorption liquid for reoxidation, and then under the action of water vapor, the absorption liquid is distilled to distill free bromine, and the distilled liquid is condensed to obtain bromine. The air blowing method has the advantages of strong applicability to bromine-containing raw materials, convenient automatic control, applicability to large-scale production and the like, and has the defects of having requirements on the feeding temperature of brine, limiting the feeding temperature range to 15-20 ℃ generally, more equipment needed by the whole set of bromine extraction device, further improving the purity of distilled products through rectification, lower industrial blowing rate and larger energy consumption of the whole set of device.
The other method is that bromine is extracted by steam distillation, chlorine is adopted to directly oxidize brine, the characteristic that bromine has higher relative volatility to steam is utilized, the oxidized brine is distilled by steam, distilled distillate is subjected to standing delamination, and a bromine layer is rectified to obtain finished bromine. The steam distillation method is more efficient than the air blowing method, but has the following disadvantages: the requirement on the initial concentration of bromine-containing brine is higher, and in addition, the distilled liquid is required to be rectified to further improve the purity of the product, so that the energy consumption is higher.
Therefore, there remains a need for practitioners in the art to design more optimal solutions and devices to further increase the level of bromine extraction technology. However, the distillation device used in the existing chemical experiments (such as small test and pilot test links) is usually heated at the bottom of the distillation tower to provide water vapor, the water vapor is used for heating the feed brine besides evaporating free bromine, and the side reaction usually consumes chlorine at high temperature due to higher reaction temperature in the distillation tower, so that the consumption of the chlorine is increased; the distilled liquid discharged from the tower top is mostly a mixture of water vapor, chlorine and bromine, and still needs multiple rectification to separate and purify, so that the problems of high water vapor and chlorine consumption, high energy consumption, inconvenient regulation and control and the like exist when the whole set of distillation device is subjected to experimental operation, the experimental effect is influenced, the experimental efficiency is reduced, and the practicability is poor.
