AI Technical Summary

Technical Problem

The existing evaporation equipment for brine bromine extraction has problems such as low heat utilization rate of water vapor, low heating efficiency of liquids and short contact time of primary acid and chlorine, resulting in low bromine extraction rate, serious energy waste and low oxidation rate.

Method used

The primary acid solution is directly heated by steam-free evaporation technology, so that the heated primary acid and chlorine are fully in contact with each other in the separation tank and are oxidized. The alternating current and coil coil windings generate eddy current to heat the metal heating plate, and the liquid is heated by reciprocating the metal heating plate, increasing the contact time between the primary acid solution and chlorine.

Benefits of technology

It improves heat utilization, reduces energy waste, increases the extraction rate of bromine and the oxidation rate of bromine ions in primary acids, accelerates the heating rate of liquids, and improves the contact effect between liquids and gases.

Abstract

An efficient energy-saving evaporation system for extracting bromine from brine relates to the technical field of bromine production and comprises a horizontally arranged supporting base, a vertically arranged separation tank is fixedly arranged at the top of the supporting base, a mixing assembly and a gas inlet assembly which are communicated with each other are vertically arranged in the separation tank, and the gas inlet assembly is communicated with an external chlorine source. A heating assembly is arranged at the top of the supporting base, the mixing assembly is communicated with the heating assembly, and a discharge pipe and a waste discharge valve which are communicated with an inner cavity of the separation tank are fixedly arranged at the top and the lower outer wall of the separation tank; the heating assembly comprises a vertically-arranged rectangular supporting frame, a vertically-arranged supporting ring is fixedly arranged on the inner wall of the rectangular supporting frame, and a coil disc type winding is coaxially arranged in the supporting ring. The problems that existing evaporation equipment for extracting bromine from brine is low in bromine extraction rate and serious in energy waste are solved; the heat conduction efficiency of the liquid heating assembly is low, so that the heating speed is low; the oxidation rate of bromide ions in the primary acid is low due to short contact time and poor contact effect of the primary acid and chlorine.
